ELEVåTOR WÅRLDIndia ™

Time To Soarby Kanika Goswami

The developing world of Southeast Asia is moving fast. Cities like Tokyo, Singapore and Hong Kong rank in the top 10 in the “2014 Global Cities Index” by A.T. Kearney. Supported by a rich past and looking forward to a brilliant future, even smaller countries, like Bangladesh, despite their political turmoil and economic issues, are firmly set on the

path of industrial development. If the recently held International Elevator and Escalator (IEE)

Expo in Dhaka was any indication, that city and other urban centers in Bangladesh are all set to grow very fast, vertically. A government regulation mandating a certain amount of open space to be left during construction of buildings in the country is the reason. Pushed by the momentum of urban migration, habitation spaces in the country are changing swiftly and need to become more affordable. This is the cue the building and real-estate industry has waited for and needed. With a good number of global brands exhibiting at the IEE Expo held at the tasteful International Convention City in Bashundhara, Dhaka (p. 22), the field seems to be open for brisk business in the sector.

In the meantime, a positive budget and even more optimistic plans for high-tech changes to the way Indians live is driving every sector of the industry toward growth. The prime minister’s call to “Make in India,” a 100% financial commitment from at least 10 tier-II cities across the country, is having an impact. The elevator market is set to grow at a fast rate, and even more than domestic consumption, Indian brands of elevators and escalators (as well as component manufacturers) are set for takeoff.

Encouraging standard operating procedures and investment structures for foreign organizations that want to set up manufacturing in India will certainly allow for savings on foreign exchanges and get the quality of every elevator and escalator component, as well as the complete units, closer to global standards.

India is forecasted to reach 100,000 new elevator installations per year in 2018. Is the industry ready to deliver? Certainly, say the players. The biggest hurdle, however, is an interesting one. In a country that produces brains that have a majority stake in Silicon Valley, California, there aren’t enough educational courses for elevator engineering. That seems to be the challenge, and the industry wants to meet it before the deluge starts. Hopefully, we will be in time.

This issue of ELEVATOR WORLD India talks about the changing skyline in some lesser-known, but nonetheless, beautiful and optimistic parts of the world, with hope looming up like a mammoth silver cloud for the future. 🌐

Three Dozen Additional Escalators for Railway Stations

Railway stations at New Delhi, Nizamuddin and Shahdara are among those scheduled to have escalators installed in the current fiscal year, the Business Standard reports. In all, 36 escalators are planned for an array of stations to help ease traffic flow. They are in addition to 12 already in place at stations such as New Delhi, Old Delhi, Nizamuddin and Vihar.

Escalators, Elevators for Bengaluru Skywalks

Twenty-two of the 25 new skywalks planned in Bengaluru will be outfitted with up escalators, with the remaining three outfitted with elevators, the New Indian Express reported. The Bangalore

Development Authority solicited bids in the spring and planned to award work in early summer. Each unit will be built according to the height of the skywalk. The parts of the city where officials observed the most foot traffic are receiving skywalks. The work is expected to be finished in June 2016.

Monorail Escalators Go LiveNearly 30 escalators at seven monorail

stations along the Chembur-Wadala route in Mumbai were scheduled to be operational by the end of February, Hindustan Times reported. There are four escalators — two from ground to concourse and two from concourse to platform — at each station. Those at Wadala station were first to go live in

January, the Mumbai Metropolitan Region Development Authority said. Other stations that have or should soon have escalators are Chembur, VN Purav Marg, Fertilizer Colony, Bharat Petroleum, Mysore Colony and Bhakti Park.

Escalators Replace Foot Overbridge at Chennai Station

Chennai Metro Rail Ltd. planned to replace a steep foot overbridge connecting Park Station and Moore Market with escalators in February, The Hindu reported. The work was scheduled to take place in February. Many people had been reluctant to use the steep bridge, leading to heavy foot traffic in the street and accidents. The escalators are expected to help that situation.

Puranik Receives Global Wittur Award

Vivek Puranik, head of Sales for Wittur India, was awarded the “Individual Contributor Award” by the Wittur Group. A presentation was held in Brixen, a small skiing city in the French Alps. The award is presented annually to five individual contributors chosen by the Wittur executive management team within the global Wittur Group. Puranik was awarded for his significant contribution in introducing Wittur products in India and increasing market share of the company.

Vivek dedicated the award to the hard work of the entire Wittur India team. The company increased sales by more than 100% year-on-year since its inception in 2012. Its customer base now exceeds 300. In its three years, the company has successfully introduced many variants in elevator doors and cabins made in India. It has also established service support teams across the country to help customers in technical support, training and product information. It has future plans to introduce more products for sales in India, including full kits for machine-room-less elevators.

Unlicensed Units Persist in Kerala

Despite passage of a 2013 law requiring operators of lifts and escalators to apply for and obtain licenses, 1,558 units continue to operate without them in Kerala, The Hindu reports. In January 2015, the state’s department of electrical inspectorate had granted 1,248 licenses. Unlicensed units are mostly in apartment complexes, where property owners and managers are reluctant to invest in required changes, such as the replacement of collapsible doors. Authorities, meanwhile, are reluctant to disconnect unlicensed units’ power — another provision of the law — for fear it will inconvenience residents.

Hitachi Outfitting Mumbai’s Crescent Bay with 58 Units

Hitachi Lift India has been hired to outfit the six-tower residential development Crescent Bay in Mumbai with 58 energy-efficient elevators. The towers range from approximately 40 to more than 50 stories. L&T Parel LLP placed the order, which consists of 47 passenger lifts: 35 4-mps, 1150-kg units and 12 1.5-mps, 630-kg units; and 11 4-mps, 1600-kg service lifts. The system will utilize destination control, and the units will feature etched stainless steel and mirrors. The elevators will have seismic-detecting functionality, and they will travel quickly to the nearest floor to allow passengers to evacuate during an earthquake. 🌐

Nepal a Booming Market; OEMs Tap DistributorsReal-estate prices are rising, and infrastructure is being built in Nepal, making it a

booming elevator/escalator market, the Nepali Times reported. Schindler and ThyssenKrupp Elevator are among the first to enter the market, tapping authorized dealers Techno Trade Pvt. Ltd. and Infratech, respectively. Bharat Vishnani, ThyssenKrupp Elevator (India)’s managing director for India, said he is optimistic about Nepal’s continued growth. As of March, ThyssenKrupp Elevator had already sold 20 units to housing projects and expected its market share to grow. High-rise buildings are multiplying in the capital city Kathmandu, which has few elevator-company representatives. Sumit Agrawal, Techno’s Business Development director, said he is optimistic Schindler products will be in high demand among Nepali customers.

ThyssenKrupp Elevator to Outfit Iconic Chinese Tower

ThyssenKrupp Elevator is providing 34 elevators and 16 escalators for Cube Tower in Foshan, China, a unique 143-m-tall building made of nine vertical cubes of varying sizes. Intended to be the new cultural center of the city, Cube Tower will house a theater, exposition hall, and leisure and conference areas. ThyssenKrupp Elevator intends to complete the project in July. The company states:

“The unusual shape and structure of the building presents numerous engineering challenges, which require ingenious solutions. As a testament to the company’s customer-centric focus, ThyssenKrupp will supply custom-designed cabs to suit the specific requirements of the tower, including two doors per cabin to allow evacuation of passengers via an elevator in an adjacent shaft, while still meeting all elevator safety codes.”

Schindler System for Indonesia’s Tallest Tower

Schindler is outfitting what will be Indonesia’s tallest skyscraper, the 330-m-tall, 81-story Thamrin Nine Tower 1 in Jakarta, with a complete vertical-transportation system that includes 32 elevators and 34 escalators. Installation is underway, and the building, which will house offices and a Hilton hotel, is scheduled for completion in 2017.

Units being installed include several panoramic, 8-mps elevators, as well as a 280-mT-capacity elevator capable of carrying vehicles up 280 m in less than 2.5 min. The system will utilize Schindler’s PORT destination-control technology and be monitored by Schindler’s Lobby Vision® security system. The elevators are Schindler’s electricity-regenerating 7000 Series. The 5.5 million-sq.-ft. building, part of a larger, mixed-use development, is expected to house up to 25,000 tenants. The vertical-transportation system is expected to serve approximately 6,000 passengers daily.

Potential in AfricaTall buildings are planned for Casablanca and Lagos.

Africa’s Tallest Building ProposedA 540-m-tall tower has been proposed by

Dubai-based company Middle East Development LLC. According to Arabian Business, it would have 114 stories and cost US$1 billion. Located in Casablanca, Morocco, it would achieve the title of Africa’s tallest building, dwarfing the 223-m-tall Carlton Centre in Johannesburg, South Africa. Tentatively named “Al Noor Tower” (“Tower of Light” in Arabic), the moniker is expected to be changed to honor Mohamed VI, king of Morocco.

Overt symbolism plays a big part in the design: the height of 540 m comes from Africa’s 54 countries, the 114 floors corresponds to the number of chapters in the Koran, and the pattern adorning the façade will represent Africa’s 1,000 languages. The building will include a seven-star hotel, a business center and a shopping mall. Work on the edifice is to begin in June and be complete in June 2018.

Nigeria’s UNILAG To Build High Rises in ExpansionThe University of Lagos (UNILAG) intends to begin building “skyscrapers” in the

coming years as part of its efforts to mitigate the effect of land shortages, the Nigerian Tribune reported. Five buildings have been scheduled for construction, with the first being a 10-story library block to be underway this year.

Located in Nigeria’s most populous city, the institution feels it needs to maximize the use of its available land while expanding. UNILAG Vice Chancellor Dr. Rahamon A. Bello explained:

“Being a city school and being already closed in by development, we don’t really have anywhere else to expand to. And, quite a large portion of the land that was acquired for the University of Lagos (up to 40%) is marshy and cannot easily be developed. . . . So, we are going to begin to grow vertically. Most of the buildings you will be seeing in the coming years will be vertical buildings; our major buildings will henceforth be high-rise buildings.”

46-Story-Tall Resort Planned on Dubai ArchipelagoBold design looks to return to Dubai after a post-2008 lull in the form of the US$1.4-

billion, 46-story Royal Atlantis Resort and Residences, The National reports. Designed by New York’s Kohn Pedersen Fox and developed by Investment Corp. of Dubai on the manmade archipelago Palm Jumeirah, the massive concrete and glass structure features overhangs and sky gardens, as well as a swimming pool 90 m in the sky. It is set to include 800 hotel rooms, 250 residences and retail, and is scheduled for completion by 2017.

MitsubishiAsian elevator branch establishes Thailand presence, installs eye-catching escalators in Shanghai.

AMEC Building US$20-Million Thailand FacilitiesMitsubishi Elevator Asia Co. Ltd.

(AMEC) is investing US$20 million in a new production facility and test tower in Chonburi Province, Thailand, to increase annual production capacity there by more than 50% to 20,000. The three-story, 4,800-m2 facility and 59-m-tall test tower are scheduled to be operational by May 2016 and December 2016, respectively. AMEC Managing Director Yoshikatsu Hayashi stated:

“Together with our new R&D center, which we established in October 2014 to develop and evaluate elevator and escalator parts, the new factory and test tower will enable us to increase our procurement of parts in the local Thai market for enhanced cost competitiveness and reduced manufacturing lead times.”

Unique Spiral Escalators Part of Mitsubishi Electric OrderMitsubishi Electric has delivered a 51-unit order to Shanghai New World Daimaru

Department Store, a new 12-story mall scheduled to open in May. The order includes panoramic elevators and 12 of Mitsubishi Electric’s proprietary spiral escalators located in the central atrium and serving six floors. It is the largest spiral-elevator order for a single project the company has ever received.

Developed in 1985, the spiral escalators’ “highly sophisticated design and wide perspective give passengers the astonishing feeling of gliding through the air in graceful arcs.” Mitsubishi Electric opines:

“The challenge to building a curved escalator is that horizontal speed decreases as it moves along the slope, making circular designs impractical. Mitsubishi Electric’s engineers overcame this dilemma by inventing the Center Shift Method, shifting the center of the circle around which the escalator rotates in response to the degree of gradient, realizing smooth rotational movement in perfect harmony with vertical movement.” 🌐

Turkish Governor Bans Short Elevator Trips

Dursun Ali Şahin, governor of Edirne, Turkey, has banned elevator trips of up to three floors for the able bodied in the city’s public and private buildings, various outlets, including the Daily Sabah, reported. Aimed at fighting obesity and having gone into effect on January 1, “Let’s Take the Stairs Instead of the Elevator” exempts elderly and disabled persons. An elevator attendant is to supervise the process in institutional buildings. Şahin is the same lawmaker who has enforced health-oriented rules in the past, such as requiring cafés to serve tea with only one sugar cube, rather than the traditional two.

Escalator-Equipped Foot Overbridge Opens in Myanmar

A third foot overbridge outfitted with a pair of escalators was set to open earlier this year in Yangon, Myanmar, Eleven Myanmar reported. Intended by the city to ease pedestrian traffic in busy locations, the foot overbridge stands 16 ft. off the ground near Kaba Aye Pagoda and a bus stop. Two escalator-equipped foot overbridges opened in 2014 in Mingalardon and on Strand Road.

by Kanika GoswamiBangladesh is a small country, but with rapid growth in its population over the

last few decades and an inordinate amount of urbanization, its need for urban dwellings has gone up manifold. Over the last 15 years, the demand for real estate in its capital of Dhaka has pushed up real-estate prices and, consequently, concentrated good housing in the hands of a small percentage of the population. Estimates say that only 12% fall into the category of “well off ” in the country.

The 160 million people who inhabit the 147,570 km2 of the country need homes, and they are not coming cheaply. The most feasible housing solution for a burgeoning population centered in the four major urban centers of Chittagong, Dhaka, Rajshahi and Khulna was multilevel homes in high rises. Additionally, government regulations are very strict about keeping at least 40% of the land area free of construction. So, the only way to grow is upward. As a result, the pressure is on the real-estate industry to provide affordable multistory housing in the urban centers.

This, then, is the boom time for the elevator industry in Bangladesh. Recognizing the opportunity for the country’s real-estate industry, Virgo Communications organized an event that would open its doors to simple components of the business – good building materials at competitive prices, business partnerships and networking. The company presented the International Elevator and Escalator (IEE) Expo 2015 on February 10-12 at the under-construction International

Convention City in Bashundhara, Dhaka, Bangladesh. This was the first time the IEE Expo was held outside of India.

The event was graced by Mosharraf Hossain, minister, Ministry of Housing and Public Works, Bangladesh. It included enthusiastic participation by the Real Estate & Housing Association of Bangladesh (REHAB) and more than 70 vendors from India, China, South Korea, Italy, Spain, Greece, the U.A.E., Saudi Arabia, Kuwait, Switzerland, Germany, the U.S. and France.

The expo served to represent a new beginning of the elevator industry for Dhaka and was received enthusiastically by the builder’s industry of the country. Many local businesses participated, reporting benefits in terms of business, as well as contacts for networking. An annual recurrence of the event was requested by several participating vendors.

The expo showcased the latest elevators, escalators and related components from leading industry players. It spread across two halls over approximately 3,000 m2 and welcomed more than 2,000 visitors. The rapid growth of the building and construction industry in Bangladesh is driving the market for the emerging elevator and escalator industry. Organizers feel the country’s sector is growing rapidly and that the time, nature and scale of the expo were ideal. Participants found that the delicate political situation in Bangladesh did not deter the expo’s success.

Speaking on the occasion, Anitha Raghunath, director of Virgo Communications, said:

“It was an excellent beginning and definitely brought to light the immense opportunities that exist in the elevator and escalator industry of Bangladesh. We saw an extremely enthusiastic response from both participants, as well as visitors. I am really happy to say that the whole environment was extremely conducive for the development of this sector.” The builders and real-estate community in Bangladesh said they saw an

opportunity to grow and offer their own products at a quality comparable to that of global leaders. Alamgir Shamsul Alamin, president, REHAB, and director, Shamsul Alamin Group, one of the leading builders of Dhaka commented, “I

warmly welcome the first IEE Expo to Dhaka. This event supports the real-estate developers in Bangladesh to come across newer and quality products, which will be cost effective and add more value to the customers.”

IEE Expo Dhaka 2015 helped create brand presence and explore partnerships and joint ventures by providing a global opportunity for building and construction industry players. It also promoted the interaction and networking of elevator experts and brands. Tarunesh Mathur, manager, exports, Schindler, said of the event:

“This is a first for Dhaka, and the first for me, as well. The response was quite good – more than what we expected. People have been showing interest in our stalls, and. . . our brand is getting a lot of footfalls. I think this is a very strong platform in Dhaka, I have been pleasantly surprised with the mix of visitors, a lot of vendors, a lot of architects who are coming in, and a lot of interest from the public works department, so we have been very happy. There have also been lots of people who are end users. For me, it’s all the same, because at the end of the day, they are customers. I think we are in the right industry in the right time. Bangladesh is booming; we have a city [that] is growing at 3.5% every year. Urbanization creates a need for elevators. Events like this should happen more often, definitely at least once in two years.”Uday Roy, general manager, ThyssenKrupp Elevator

Bangladesh, added:“This has been a good decision, to be part of this

exhibition in Dhaka. There has been a good return on investment for us. I think the quality of visitors is [greater] than our expectations; we were not expecting so many visitors due to the political scenario. But, it was a very good day, and this initiative would be good on a biannual basis. Your initiative to make the awareness program will be very useful for Bangladesh and Dhaka, and we must appreciate this.”Participants from Bangladesh were excited to have an

opportunity they had long awaited, while those from outside were pleased to find a new business opportunity open to them. Biplob Mondal, managing director, Future Powertech Ltd., remarked: “This is the first elevator exhibition in Bangladesh, which makes a great platform for both national and international elevator companies for longer business [relationships] that support our elevator industry.”

The well-received event was supported across the allied industries, as well as the governance. Enthusiastic visitors and participants have indicated they would like an event on this scale with similar organization to be held in Dhaka at least annually. 🌐

Observations from the Show

“First of all, this event will help to develop our local market. Next year, we will see the world business in [Bangladesh’s] local market. Yesterday, we sold five units, so it has been good for us. You must have this visit annually.”

“To be honest, when we heard this event was to be held in Dhaka, we

thought we would be here for a day or so. But, when we are here, it’s a

wonderful experience, this kind of crowd. [Over the] last three to four

months, I have been attending various exhibitions and [have been] very

impressed. All visitors are very positive, and I am very happy. The event should

be on a regular basis.”

“This is the first international expo in Bangladesh. We have never had this

kind of exhibition before. We have been expecting it for a long time, but,

unfortunately, it didn’t happen. We are happy that you have got it now, and we are expecting more in the future. What

we learn here is because we interact with our competitors, as well as our clients. Now, we know these are the

kind of companies [this type of event will draw], and this is what they offer.”

Toward the 100,000 MarkHow well the Indian elevator industry is prepared for reaching the sky of new installations

The Indian elevator industry is soaring toward the 100,000 new-installations mark in the next three to four years. Are we ready for the ride? The rapidly growing real-estate sector, the fast-aging population and the recently introduced innovative technologies, aided by Prime Minister Narendra Modi’s “Make in India” program combine to benefit the elevator industry.

A recent report prepared by Netscribes is very optimistic about the elevator market, both in India and worldwide. While the global elevator market is poised to grow at a compound annual growth rate (CAGR) of 6.5% (fiscal years 2013-2018), the Indian market will grow at almost three times that rate. Standing as the second-largest elevator market in the world, India’s CAGR is estimated to be 16% for the same period, touching 89,000 units in 2018. Driven by a rapid growth in real estate, rapid urbanization, higher disposable incomes and optimistic foreign direct investments (FDI) flow, this number could be even higher. Fueled by the push towards infrastructure development in the country, the sky is the limit.[1]

Composed of two segments, the new-equipment installations and maintenance and modernization segments of already-installed equipment, there is a clear geographic divide in specializations. While emerging markets are driving the new-equipment installation market, the maintenance and modernization segment is still dominated by Europe and some North and South American countries. The faster-growing sector is, of course, the emerging markets – China, India and Brazil – while the European and American segments show stable growth.

Sreelakshmi Menon, director – Marketing & Communications, KONE, commented:

“The Indian real-estate sector is an integral part of the economic performance and is expected to be a major beneficiary in the coming economic growth. The country’s growing urban population is equivalent to the total population of certain advanced economies. It is estimated that the size of the real-estate sector may increase fivefold to reach US$700 billion by 2025.”Newer government initiatives, such as

massive plans to set up “Special Economic Zones” and welcoming FDIs and private-equity investments in real estate will only add to the bottom line here and create the boom for the real-estate sector that will push for an increase in allied sectors, like elevators and escalators.

A big factor has been exposure, as the Indian industry, especially information-technology (IT), has opened up. Said B.S. Kumaraswamy, director – Monteferro India Guiderails and Elevator Parts Pvt. Ltd.:

“Today, exposure is much more, so lifestyle demands are higher. Also, there is much more awareness: exhibitions and expos that are being conducted, are also adding to information. Earlier, it was a sellers’ market – we could sell anything – but now, the range of products needs to be bigger; customers ask questions. In the future, there will be real-time technology; brands like Mitsubishi

are putting up factories in Bangalore; they will bring [the] best of products, and the market is aware and willing to pay.” The next big driver is the rapid urbanization in India. Over the

last eight to 10 years, approximately 2,700 new cities have been added to the urban areas list, taking the number of cities in India to 7,900. A growing IT; IT enabled services; banking, financial services and insurance; and manufacturing sector based on office complexes together constitute 75% of the total office space available in India, and the demand for elevators is rising with their growth. Future cities and developing economies hold a lot of potential for infrastructure growth; therefore, urbanization is a major driver for the elevator segment in India.

As Sebi Joseph, managing director, Otis India, said:“340 million people, or 30% of the country’s population,

currently live in cities. According to a recent McKinsey report, by 2030, it is expected that cities will house 590 million people, or 40% of the population, and that India will have 68 cities with populations of more than 1 million. As urbanization continues and the need for housing grows, India’s elevator industry will continue to grow just as rapidly.” In addition, as the population of cities

grows, demand for malls, shopping areas and hypermarkets is growing, as well. So, at 100 million sq. ft., the retail industry is also a big consumer of elevators.

To ensure a competitive urban infrastructure, metros and international airport projects have also been planned in most tier-I cities, and this has only added glitter to the real-estate boom. At an average cost of INR300,000 (US$4,798) for buying and installing an elevator, the market is not really extremely price conscious, either.

A small but significant reason for demand is also the aging Indian population, though it is a slow process. Today, India is one of the youngest countries in the world. But, over the next five years, the trend may slow down, with advancements in medical support. While India had approximately 61.1 million people aged 60 plus in 2010, that number is touching 300 million this year. At this rate, this will be a big reason for residential, as well as public, elevator demands. In the next five years, elevators could become a standard fixture for every apartment.

Industry StandpointIn the Indian industry, every brand’s portfolio has a mix of

maintenance packages and new products. Since the market still has a large number of lifts using old technology, the opportunity for technology upgrades is huge. Bigger companies have their own technology modernization departments that will be profit centers by themselves, sometimes with bigger revenues than new sales.

Then, there are the next-generation products that will add value to the market, and there are quite a few new products in the market that will focus on advanced technologies, environmental awareness and higher safety compliances. Most of these brands will also have stronger R&D and training arms, as well, which will add more value to the industry for future growth.

“India is the world’s second-largest elevator market,” explains Antony Parokaran, CEO – Schindler India. He continues:

“Our new supply-chain unit in Pune represents a key platform for our growth strategy and will enable us to continue offering

competitive products to our Indian customers with even shorter delivery times. The Schindler factory campus is 200,000 m2, which includes an elevator plant and R&D center with future plans for [an] escalator plant. The elevator plant was certified by Bureau Veritas Quality International for ISO 9001: 2008 quality management system and was awarded the ‘IGBC GOLD’ rating. The new factory is integral to Schindler’s growth strategy in India and makes it more competitive in the market, enabling a higher market share and bringing better service for its [customers].” “Knowing our market, customers and consumers is very

important in any industry, and KONE is no different,” said Menon, continuing:

“Since our inception in India, we have been manufacturing in Chennai. . . . We are also developing a new state-of-the-art facility to cater to this growing demand. Our history of innovation is one of our success factors, and we always believe in being closer to the customer and consumer to innovate better. [This is the] main reason for [us] having our Indian Technology and Engineering Center (ITEC) in Chennai. ITEC has been playing a key role in supporting KONE India’s market development. We have always made systematic and long-term investments into our R&D capabilities to strengthen our innovation leadership in the elevator and escalator industry. This has certainly benefited the industry, and we have [been] featured for the fourth time in the Forbes list of 100 most innovative companies. With stronger R&D, engineering collaboration and an expanded facility here in India, we can serve the growing Indian market with even more innovative People Flow solutions.” Adds Joseph of Otis:

“Otis India is positioned to deliver to this growing segment, with the recently expanded facility in Bengaluru that has tripled in size and doubled in manufacturing capacity. The facility includes a new elevator test tower, standing at a height of 51.2 m with the ability to test up to six elevators at a time. Co-located with the factory is Otis’ R&D center in India that has also significantly expanded its engineering capacity in recent years.”Sreekumar Nambiar, head of Sales and Marketing for Fujitec

India, said:“There are reports that the Chinese market

is flattening out; therefore, the Chinese companies will aggressively look towards India. We can expect a slew of [unheard-of] Chinese brands to come to India soon. We think that the market demand will be fulfilled by them in supply. Installation is [a] whole different story, as even with the current demand, companies are not able to complete on time. The only way out will be for elevator companies to establish large training centers to ensure a captive manpower base. There will have to be discussions at the legislative level to include [the] elevator-installation trade in industrial training institutes (ITI) in future.”

Make in IndiaModi’s call to “Make in India” seems to have had an impact in

the sector, as well. Said Menon:

“The global manufacturing landscape has been evolving at a fast pace. While continuous change in wages, energy costs, productivity and currency rates are shifting the global standings on cost competitiveness, factors other than cost are becoming more and more important for companies to decide the location for sourcing and manufacturing. Total manufacturing cost is central to decide any manufacturing location. If we were to assess India’s performance on the dimension of cost competitiveness, [we would find] India has the second-lowest manufacturing cost when compared on a global level. The elevator and escalator industry, if it were to propel the growth of its component-manufacturing sector, would need to maintain its cost advantage in this environment of fierce competition by keeping a check on the increase in wages and other factor costs. This is the easiest of the tasks in front of us. The tougher task for our industry is to address the competitiveness in the non-cost factor. This is where the government’s role becomes very critical to gain investor confidence, which has been addressed in this union budget with special impetus given to ‘Make in India.’ If we are able to address these non-cost factors successfully, then most component suppliers will [be] able to better support the growing industry.”However, she added that while cost competitiveness is a critical

criterion for any company to decide its manufacturing location, other factors play a key role, too. Factors like infrastructure, operational ease of doing business, political stability and transparency, tax structure, and access to credit also carry substantial weight. While India scores well on cost competitiveness, the country needs to focus more on these other factors. Added Joseph, “The ‘Make in India’ initiative will enable a deeper focus on what the Indian customer and building segment [are] looking for and match that with our continuing ability to offer the best in technology, quality and safety.”

Indeed, the smartest move for component, as well as elevator, manufacturers would be to step into the country, take advantage of the encouraging environment and set up a manufacturing unit. As Kumaraswamy said, “At Monteferro, we are planning to set up a facility in India in the near future to take advantage of ‘Make in India.’ Research is on, on the ways we can position ourselves in India as a manufacturing setup.”

“Make in India” will be the way to go forward, as customers will have the comfort of dealing with Indian companies, rather than Chinese ones, which are highly unpredictable. Nambiar added:

“Our engineering understands the needs of the Indian markets and, therefore, is able to satisfy customers’ unique technical requirements. Having said this, Indian companies will hugely be dependent on Chinese companies for components, as India still has a long way to go in the manufacture of drives and machines. Though there [are some] multinationals that have set up manufacturing in India, that only suffices for a small percentage of the requirements. The large [percentage] is still important. The drawback India has is lack of quality and the fact that government regulations don’t make manufacturing easy; it is far easier to import.” Unless this scenario changes, Nambiar feels, “Make in India”

may not resolve all issues at hand.

Challenges and SolutionsThis growth, while being the revenue driver for the

manufacturers, will also come with its own set of challenges, the

biggest among them being safety issues, mostly due to badly or hardly maintained equipment; lack of trained manpower; and, in India, the lack of enforceable and stringent regulations. It is common knowledge that elevators in many commercial establishments, as well as residential buildings, are unsafe and becoming more so, largely due to poor or no servicing and maintenance. New machines need maintenance once every two years, which is a dictum not always followed.

Additionally, there are virtually no training institutes for elevator engineering in the country, nor is such training offered as a course. So, the only trained personnel we can expect to have are those with a couple of years of experience, and once this expansion starts, there will be a shortage of trained manpower that may hit the maintenance market hardest.

Adds Kumaraswamy: “The industry needs more manpower; we are not geared up to

meet the surge in demand that’s expected, in terms of trained people. We have no education in elevator engineering, and the only way to learn is at work. Elevator sciences comprise of a lot of sciences and technologies in one place, and no proper education in the field is a huge drawback. Engineering colleges need to add elevator engineering as a curriculum with a full-fledged syllabus and government-approved curriculum so we can produce engineers in the field. Or else, it will become a critical issue, and we will not be able to meet a lot of demand for service, even if the supply orders are met.”As a result of no professional training, operators and

maintenance staff are taken on contract and outsourced another level, which means shorter retention periods, low wages and lack of standardized skills.

Fujitec handles the issue internally, said Nambiar: “As far as the installation readiness goes, we have a full-fledged

elevator and escalator training center in our factory. Here we pick up ITI trainees who undergo classroom and practical training in our test shafts before being sent out to various sites. We will ensure that our training program produces high-quality technicians.” So does Schindler, said Parokaran:

“At Schindler, we have proactively invested in training our employees on elevator installation and maintenance. Our three state-of-the-art training centers, one each in Noida, Bangalore and Mumbai, ensure that each of Schindler fitters and service technicians is trained and certified to work on our equipment and our customers know that their elevators are in safe hands.”“While the sector offers ample opportunities for development

across different verticals, there are certain intrinsic challenges that hinder growth of the sector,” said Menon, continuing:

“Factors such as inadequate funding channels, shortage of skilled manpower and technology, slow development of urban infrastructure, land-related issues and [a] prolonged regulatory process for clearances are some of the key challenges facing this sector. Realizing the challenge at hand, several key reforms have been introduced recently, and many more are lined up to improve [the] global inflow of funds and promote growth of the sector.”

The Way AheadFinally, what does this growth mean to India’s leading brands?

Menon said that most prefer to give a better direction to their products:

• Issue 2, Volume 8 • elevatorworldindia.com 31

“While most of the elevator manufacturers are on an expansion mode to cater to this growing demand, [the] importance of safety and concern for the environment need to be addressed. At KONE, we constantly develop products and solutions that contribute to sustain urban development by developing energy-efficient solutions that move people smoothly and safely in urban environments.”Adds Joseph:

“A natural progression for any growing industry is consolidation. Growth also enables investment and technological innovation. Otis looks forward to delivering advanced technologies as an industry leader. For example, the Gen2® Switch is designed to continue running in power outages. The Gen2 Switch features environmentally sustainable design, can be coupled with alternative energy sources like solar panels and can lower energy use by 80%. In a move to strengthen our presence in the country, we have expanded our Bengaluru manufacturing facility by tripling the size of the factory footprint and doubling manufacturing capacity. We have also recently launched the Gen2 Infinity, which is built on Otis’ flagship Gen2 technology platform and caters to the industry’s need for a faster elevator.”There could be negatives, as well, as Nambiar points out:

“Quality could be the victim when the volume goes up. As the demand goes up, there is a very good possibility of shortcuts being taken in both quality of product and installation. This could be quite dangerous, as elevators can cause fatalities. There needs to be a strong commitment from the companies to ensure that a certain quality level in manufacturing is maintained. We had already foreseen this growth, and, hence, we [built] a factory about three years ago, manufacturing elevators from 1 to 3 mps, which we think will be the most common specifications. We currently suffice our local demands and export to Southeast Asian countries, which talks about our quality. As the volumes [have arisen], we have planned the second phase of our plant, which will double our capacity, ensuring smooth supply to our customers.”Parokaran stated:

“Schindler will continue to grow at a rate faster than the market and maintain the highest standards of safety and reliability. To achieve this level, Schindler continues to develop new products based on market needs, which are energy efficient and provide green mobility. With its full-fledged factory in India and the upcoming R&D test tower, Schindler demonstrates high focus on development and sustainability.”The Indian elevator industry is poised for take-off. Cost

effectiveness and safety innovators, along with green technologies, are the focal points of this growth. The market is hugely unorganized, and only the top 5% is served by known global brands. These, however, are setting the standards of product innovations – Otis and KONE are installing elevators that operate at a speed of 6-7 mps. Also, the trend toward machine-room-less elevators is on the rise, and fitting the traction machine at the top of the shaft, thereby saving space and building construction cost, is becoming more and more popular. The next step is smart elevators with environmentally friendly technologies that will also help cut the carbon footprint.

Company Spotlight

Gen2 Infinity from Bengaluru“Make in India” facilitated at Otis factory, where a 51.2-m-tall test tower is installed.

Otis came to India in 1862, setting up its first elevator in the country in the Viceregal Palace in Kolkata, which is now the West Bengal government’s Raj Bhavan (ELEVATOR WORLD India, 3rd Quarter 2014). Otis, one of the oldest elevator brands in the country, set up a Bengaluru unit at an industrial area on the outskirts of the city called Jigni in 1996. Since then (and mostly since 2010), the factory has grown multiple times – a production facility has more than tripled the size of the factory footprint, while its manufacturing capacity has more than doubled, from 5,000 to 10,000 units per year. An investment in excess of INR10 million (US$160,477) was made over the last four years.

Recently, the factory has undergone a transformation to make it a leaner unit in terms of energy consumption. It incorporates various facets of environment conservation, such as using sunlight for illumination and harvesting rainwater via tanks.

A new landmark was announced at this factory this quarter – the installation of a new elevator test tower. The tower stands at a height of 51.2 m and is equipped to test up to six elevators at a time. It also has mechanical and electrical test labs equipped with high-end equipment and staffed by a technical team to ensure the products meet Otis’ safety, quality and reliability standards. This addition to the facility will give the company the capacity to

produce a wider range of smart, energy-efficient products localized for the Indian residential and commercial segments.

The latest product in the kitty is the Gen2 Infinity elevator model aimed at the mid-rise residential sector of the Indian market. Operating at a speed of 1.75 mps, this passenger elevator has a compact machine room and targets residential buildings up to 30 floors. Built on Otis’ flagship Gen2 technology platform, it is intended to expand the market range of the Gen2, taking it beyond its current applications in the commercial sector. It will be exclusively manufactured at the Bengaluru facility.

Speaking on the occasion of the Gen2 Infinity’s launch, Sebi Joseph, managing director, Otis India, said:

“Otis India is pleased to build upon our 100-year history in India by strengthening our manufacturing presence in Bengaluru. The Bengaluru factory expansion underscores Otis India’s focus on local innovation and continued investment in manufacturing and research activities.” Joseph emphasized the fact that localization

is being increased in a phased manner, explaining, “About 70% of the components are manufactured locally, and we plan to include all the parts in this soon.” Citing India as the second-largest elevator market in the world, he pointed out that the country will soon be seeing double-digit growth in its elevator industry, given the huge growth planned for the infrastructure. While the current Indian market is approximately US$1 billion annually, the Bengaluru market sees around 5,000 units sold each year.

Otis has a double-digit market share and around 60% of the service market as well. The

This addition to the facility will give Otis the capacity to produce a wider range of smart, energy-efficient products, localized for the Indian residential and commercial segments.

company’s expansion is expected to be concentrated in tier-II and -III cities poised for huge growth. Otis has coverage of 80% of the country, and with the urban population mark hitting 40% by 2020 and higher aspirations for standards of living, the demand for elevators is set to go up dramatically. The replacement market is not seeing very fast growth (approximately 10% a year), but it will be poised to increase going forward.

In addition to these numbers, given India’s current small elevator density compared to worldwide figures, there is room for growth. “We stand at 0.16 elevators per 1,000 people, as against a small country like Spain – 19.8 per 1,000 people,” Joseph pointed out. The 100 smart cities planned by the new political regime will only add to this demand, and Otis plans to supply it with its next-generation products.

All of these factors are ensuring that Otis’ new products are geared to meet the evolving expectations of the Indian market that should see serious growth over the next two to three years. 🌐

Dubai Mall Metro Link submitted by Borja Brañanova, ThyssenKrupp Elevator UAE, and Begoña Flores Canseco, ThyssenKrupp Elevator Southern Europe, Africa and Middle East

MovingWalks

C a t e g o r y 5

In 2009, Dubai became the first city in the Middle East to have a fully operational urban train network. With more than 10 million visitors every year, the metro system provides vital transportation infrastructure for the city. The Dubai Mall/Burj Khalifa Metro Station is one of the busiest in the city. It serves the business hub on Emaar Boulevard, the Dubai Mall and the Burj Khalifa. However, it is just far enough to make it very uncomfortable for commuters to walk from the station to these locations in Dubai’s hot climate.

When operation began in 2009, there were several conversations about covering this distance. In 2012, the solution came in the form of an 820-m-long, temperature-controlled glass footbridge that ThyssenKrupp Elevator UAE equipped with moving walks. Called the “Dubai Mall Metro Link,” it draws on traditional Arabian architecture styles, its façade and colorful lighting complementing the architecture and adding to the lively ambience of Emaar Boulevard.

The link provides a comfortable and environmentally friendly alternative for more than 30,000 daily commuters and visitors who would previously have preferred to take a taxi or feeder bus from the Dubai Mall metro station. “I wouldn’t have thought of coming to this place by metro with three kids and my wife if not for the walkway,” said frequent visitor Nicholas Leven from the U.K. “I would have definitely taken a taxi.” It not

only meets the needs of the metro’s passengers, it also reduces vehicular traffic, which contributes to a cleaner environment. This project is, thus, a feather in the cap of ThyssenKrupp Elevator UAE, a firm believer in sustainable efficiency.

Apart from adding to commuter convenience, the link has significantly raised the number of visitors to downtown Dubai, which hosts a series of celebratory events culminating in a spectacular New Year’s Eve gala and fireworks display. Ahmed Al Hammadi, director of buses at the Road & Transport Authority, has said:

“The opening of the link is timely, as it will help people coming in to enjoy New Year’s Eve, when thousands visit the downtown area. In the long run, the walkway will help increase Dubai Metro ridership, as well as customers to the Dubai Mall.”ThyssenKrupp Escalator Co. Ltd. in China manufactured 14 indoor Orinoco

Xtra moving walks with slim balustrades for this project. They each measure 70-120 m long and 1.4 m wide, and move at an average speed of 0.5 mps, carrying 13,500 people per hour at peak capacity. They come with EN 115:2008 certified detailing in line with the latest standards in the region. They are equipped with handrail speed sensors, missing pallet sensors and brake monitoring to ensure passenger safety. There is also a variety of other features, such as additional emergency-stop buttons at handrail level and intermittent operation with a light barrier that includes signal lights. The low-smoke, halogen-free cables and energy control with frequency converter ensure the moving walks meet sustainable efficiency standards.

In August 2012, ThyssenKrupp Elevator UAE began installing these moving walks. They were structured architecturally along the defined pathway of the

pedestrian-link footbridge, with seven sections running in different directions and at different inclinations. Despite difficult conditions, they were manufactured, supplied, installed and commissioned in a record time of five months. The project was completed in December 2012, just in time to handle the high volume of visitors for the New Year’s Eve celebration.

Given the high demands placed on the project in terms of the lengths of the moving walks, the location of the installation and an extremely limited timeframe, this was one of the most challenging projects we have ever encountered. The pedestrian bridge is located in one of the busiest areas of the city, which includes Dubai’s largest mall, tallest tower, busiest metro station and a key business hub. This was another major challenge for product delivery, and for the cranes, forklifts and specially constructed devices that had to be used during the installation period. Additionally:

♦ More than 1,068 m of moving walk was installed and handed over for usage within the short period of five months.

♦ There were major delays due to pending finalization of entry points. ♦ Commissioning was delayed due to the unavailability of permanent power supply. ♦ There were several issues during the construction of the footbridge leading to

slight deflections, which had to be dealt with during installation to ensure the leveling and alignment of pieces and components. 🌐

Asansör Istanbul Preview

The 14th Asansör Istanbul International Lift Exhibition took place on March 26-29 in Istanbul. It saw 28,000 professionals from 73 countries across its four days. Almost 440 exhibitors from 28 countries showcased their latest products and technologies across 50,000 m2. The event is significant in the worldwide elevator industry, having become the intercontinental meeting point for the global markets and acting as a gateway for trade between the East and West. It opens up the markets of North Africa, the Middle East and the Balkans, particularly for the Indian exhibitors, who find it a great opportunity to expand in those markets.

A full report on the event will appear in ELEVATOR WORLD India, 3rd Quarter 2015. In this preview of that story, some of the players who have an established presence in the Indian markets and are now expanding into the global market are quoted below.

“Turkey is the biggest market in the Middle East. We have only one agent, and I feel we should participate in an event of this significance. [The] Middle East is a huge market, and to expand our business here, we needed to participate. I believe if you are consistent in the quality [of] your products, you will have the chance of good business expansion. In the Middle East and North Africa area, we also have a stable business, and after this exposure, we hope to have more than two or three countries added to our markets.

“It has been a good return for us. A couple of order conversions will certainly cover our costs. The Balkans market was well represented there, and this will give us a greater opportunity to expand in Russia, as well. I am very happy we were there.”

– Kaushal Patel, Overseas Marketing manager, Sharp Engineers – Export Department

“This year’s Asansör was a very successful trip for us. We got a lot of enquiries from [the] Middle East, North African and neighboring regions.

“I think this is a very good investment for Indian participants, because with the number of business opportunities we get, the investment will certainly be offset. In addition to these opportunities, we get to see new technologies, receive a lot of incremental suggestions and, to top it all [off], networking is great. International visitors who may not come to India will come to these exhibitions. This gives us a chance to showcase our products to a much larger audience over the larger part of the globe.”– G.D. Patel, Marketing Director at Green

Field Control System I Pvt. Ltd.“We derived great benefit from the Asansör

exhibition at Istanbul this year. We got to expand much more into the North African countries through this exhibition. . . . We already had a good Middle East presence. Exhibitions are always great [as] meeting

• Issue 2, Volume 8 • elevatorworldindia.com 41

points to have face-to-face [contact] with. . . partners. We had a stroke of luck: MARS was negotiating with one client for the last six months, and we could meet them there and clinch this. But, in my opinion, the biggest thing is that the international customers [notice companies’] presence in foreign exhibitions over a period of time, and this gives more confidence to the buyers. For instance, I met one company from Spain, they saw me at Asansör for the third time, and that was the deal clincher -- they gave me an order. By participating continuously, we get the point across that we are quality and delivery conscious. . . . That’s the benefit.”– Mohammed Aslam Mukaddam, chairman, MAS Industries

“It was really a good experience, we got a good response, [and] we get a lot of traction in the Middle East. In terms of seeing new technologies and learning innovative things in the industry globally, I think it is a good idea to participate.”– Sanjeev Kaushal, Fitex industries Ltd.

“I visited Asansör, and as a business opportunity, the exhibition was really nice. We found the product that we are going to import in a couple of days. It definitely allows us better products, technologies, qualities [and] new concepts, especially when it came to cabins, etc. I was looking for trading products and also [learned] some new design ideas. I feel Indian companies are not yet [on] par with the rest of the world in technology and quality, though some, like MARS, have a lot of traction in the global market. Once we can compete in that market, it would make sense to exhibit in exhibitions like this one.”– Punit N. Karelia, liftshop.in and Prakash Metal Works 🌐

South Korea evokes images of Hyundai and Kia cars, LG appliances and Samsung mobile phones. Kimchi has become a popular dish in international circles, and followers of pop music are well aware of South Korean star Psy. It is certainly common knowledge that two sovereign nations occupy the Korean Peninsula: The Democratic People’s Republic of Korea, usually referred to as North Korea, and The Republic of Korea, a.k.a., South Korea. The two countries are separated at the 38th parallel by the 4-km-wide Demilitarized Zone. Most are also aware

that the Korean Conflict exacted a heavy toll on the population of the peninsula. It ended more than 60 years ago with an armistice, not a peace treaty. Approximately 29,000 U.S. troops remain in South Korea to provide support if the country is attacked.

“pursue tangible South/North consultations to resolve the North Korean nuclear problem.” The South Korean government is structured as a well-developed constitutional democracy with separate executive, legislative and judicial functions.

A visit to South Korea is, indeed, an eye opener. It is a clean, efficient, progressive-yet-relaxed country of some 50 million residents, the vast majority of whom enjoy a good standard of living. Approximately 60% of the residents live in apartment buildings, a proportion that is one of the highest in the world. The availability and standard of healthcare are among the highest in Asia, and job security is very favorable. There is a strong emphasis on education at all levels, and the percentage of young people with tertiary degrees is one of the highest in Asia. It is not surprising that South Korea is a very innovative country and a positive environment for conducting business.

With a robust economy and a high rate of economic development, it follows that South Korea has a vibrant elevator industry. It is a credit to the progressive thinking of its citizens that the first elevator was installed in the Bank of Korea building in Seoul more than a century ago. Since then, the population of tall buildings has grown rapidly, to the point where the installed elevator base exceeds 500,000 units, and over 30,000 units are being added each year.

Your author attended the third International Lift Expo Korea 2014, which included the International Lift Safety Seminar.

Lift Expo Korea 2014Lift Expo Korea was held at the COEX

Center in Seoul on October 28-31, 2014. The event was organized by the Korea Elevator Safety Institute (KESI), an

affiliated public organization of the Korean Ministry of Public Administration and Security, which was the event’s sponsor. Ian Todkill, president of the Pacific Asia Lift and Escalator Association (PALEA), was the expo’s honorary chair.

The expo was opened by Kong Chang-seok, president of KESI and chair of the expo organizing committee. Kong welcomed dignitaries and attendees, then mentioned this was the first Lift Expo Korea to obtain the endorsement of the Global Association of the Exhibition Industry (UFI). This indicates the country’s elevator industry is regarded as an important international player. He also said the purpose of the event was to promote the elevator industry and public safety.

Lee Song-ho, vice-minister of Safety and Public Administration, emphasized the commitment of South Korea’s government to public safety and commended the elevator industry for its efforts to enhance safety at all levels. He also endorsed the industry as a whole for its innovative spirit. Several other dignitaries, including Todkill, added to these strong messages. Todkill observed that the input of South Korean delegates to PALEA had greatly strengthened the organization’s credibility and capability.

The ExpoThe exhibition hall was filled with

high-quality displays representing the latest in elevator technology. The major players in the domestic market — Hyundai, Otis, ThyssenKrupp Elevator and Mitsubishi Electric — were there in force, and dozens of small to medium-sized manufacturers of elevator systems and components from both South Korea and around the world displayed their wares to a global audience. The knowledge base of representatives in the various booths and exhibits was impressive. Their insights into the technology behind their products and their willingness to share information were refreshing.

Some of the interesting items featured included:

♦ Hyundai’s NEW YZER machine-room-less (MRL) elevator, which is intended to minimize hoistway space requirements. Hyundai displayed elevators with speeds up to 10 mps.

Such elevators deploy active roller guides to enhance ride comfort.

♦ ThyssenKrupp Elevator’s Mini synergy, an MRL elevator designed to carry four passengers, intended for installation in small buildings. Also featured was TWIN, comprising two elevators in a single hoistway.

♦ Otis bridged the past, present and future with its depiction of Elisha Graves Otis at the Crystal Palace at the 1864 World’s Fair in New York City, while displaying its energy-efficient Gen2® MRL system using coated steel belt (CSB) suspension. Otis also emphasized energy-efficient regenerative drives.

♦ Mitsubishi Electric emphasized green technologies, showcasing double-deck elevators and units with speeds up to 18 mps. Some of the smaller companies also had

interesting exhibits, such as Kumbo with its inclined elevators, which can accommodate slopes of up to 75° with a variety of cable and hydraulic drive systems. Also on display were Higen’s motors and traction machines, and Haisung’s mini elevator cabs and speed-reduction units. A plethora of controllers, transducers, simulators, interface units and dispatch systems were also showcased.

Children at the ExpoIt was very inspiring to witness wave

after wave of elementary school students who visited the expo. A special room was set aside where teachers and industry experts met with the children and explained the basics of elevator and escalator operation and emphasized the need for safety. Models of elevator systems created by older children were on display.

The children were introduced to an educational program called “My Friend, the Elevator!” An elevator safety-education kit for elementary school students was handed out to teachers. The kits contain a CD and full-color, illustrated guidebook for teachers, as well as full-color, illustrated textbooks for students. The kit also includes 3D puzzles that can be assembled to form elevators and escalators, as well as leaflets on escalator safety.

The students were deeply absorbed by the contents of the lesson and seemed to enjoy the experience. Of course, the

hardhats the children received added to the fun! The kit and course material were developed by KESI in consultation with school authorities. Course contents are intended to be delivered by teachers through the school curriculum, rather than by external volunteers, as is the case in similar programs in other parts of the world.

International Seminar on Lift SafetyThe International Seminar on Lift Safety

was an important part of expo activities. It was organized by Choi Il-sub, KESI general manager, Department of Internal and International Affairs. The seminar was chaired by Todkill and was intended to provide an overview of how elevator safety issues are being addressed around the world.

Todkill spoke on the topic “Harmonization of Worldwide Lift Safety Standards.” He summarized progress made over the last 20 years in the rationalization and harmonization of prescriptive standards in many parts of the world. While there were dozens of different standards two decades ago, today most standards are aligned with one of the three mainstream ones: CEN EN 81, ASME A17.1/CSA B44 and the Building Standard Law of Japan/JIS Standards. The major driving force for harmonization is the enhancement of safety coupled with the globalization of the world’s economy. Todkill also described the efforts that have taken place over the years under the International Organization for Standardization (ISO) umbrella to promote convergence of all elevator standards. He described the current initiative aimed at developing an ISO prescriptive standard.

The next speaker was Harry Vyas, technical director, New York City (NYC) Department of Buildings, Elevator Section, who addressed the topic “Lift Safety Policy of NYC.” Vyas described the unique nature of NYC in terms of diversity of equipment with respect to age and technology. Indeed, NYC is a mirror of elevator evolution over more than a century. Vyas described the process of standards development and adoption in NYC, and the process of managing and training inspectors. He also described the organizational structure of the Elevator Section and how it is configured to implement the policies of the Department of Buildings. Vyas also spoke of initiatives to enhance the safety of older elevators, which

• Issue 2, Volume 8 • elevatorworldindia.com 47

constitutes a large proportion of NYC elevators.

The next speaker was Esfandiar Gharibaan, chair of CEN/TC 10, who addressed the topic “Lift Safety System of Europe.” Gharibaan elaborated on the spectrum of standards under the purview of CEN. He discussed the process of achieving consensus under CEN rules in Europe. Gharibaan also explained the Lifts Directive, including the Essential Health and Safety Requirements, as well as the Conformity Assessment process. He explained how EN 81, as a European harmonized standard, could be used to satisfy the requirements of the Lifts Directive, which is a law in Europe. Gharibaan described the process and content of the new EN 81-20/50 code and emphasized that experts from South Korea, China, Japan, the U.S. and PALEA helped in its development. It is anticipated that this standard will be widely adopted around the world.

Your author was the next speaker and addressed the topic “Elevator Safety Code of North America.” This provided an opportunity to review the evolution of buildings since 1860 and the role elevators have played in this process. A pictorial representation of early building construction was presented. It is noteworthy that more than 60 years passed from the time of demonstration of the first safety elevator to the publication of the first elevator code by a consortium of manufacturers. The first consensus-based code was published in 1921. It was only 50 pages thick and evolved through 20 editions to the current, 500-page document. Evolution of the code was driven by expansion of scope to cover various modes of building-transportation

systems, enhanced public expectations regarding safety and advancement of technology. Currently, a suite of codes and standards covering prescriptive codes, codes for existing elevators, performance-based codes that facilitate innovation while ensuring safety, suspension-means standards, etc., are available in North America.

The next speaker was Zhang Lexiang, secretary general of the Chinese Elevator Association (CEA), who addressed “Lift Safety System and Lift Industry of China.” Zhang described the process of adopting and enforcing safety standards in China. China is a large country with many jurisdictions, and much diversity in culture, economic development and population concentrated in cities. The adoption of standards requires consensus at many levels and government approval. Enforcement is centrally mandated and locally controlled. China has a rapidly expanding economy, and its cities are developing at an extremely rapid rate. The demand for elevators keeps increasing such that approximately half of the world’s new installations are in China. With such rapid development, safety is of paramount concern, and the CEA, the Elevator Safety Board, the enforcing authorities and the government continuously review safety requirements.

The next speaker was David McColl, convener of ISO Working Group 4 and leader of the Canadian delegation to ISO. McColl addressed “Evacuation in Building Emergencies.” Traditionally, building occupants were instructed to use the stairs, rather than elevators, during emergencies. However, with the advent of increasingly taller buildings, it is not practical to use stairs as the only means of emergency egress. McColl described the process for occupant evacuation operation (OEO) included in recent versions of A17.1/B44. It was developed by a diverse team of experts, including first responders, who used hazard analysis as a tool. OEO includes such features as water diversion, water-resistant enclosures, redundant power supplies and special operational controls and dispatch functions. In the event of an emergency, the affected floor and two floors above and below are given priority. Dynamic signage that advises the

public when it is safe to use affected elevators is required. For buildings that use OEO, trained floor wardens are required to assist occupants during emergencies.

The final presentation of the seminar was given by Achim Hütter, chair of VFA-Interlift. Hütter spoke of the rapid globalization of the world elevator industry and its effect on suppliers and users of elevator components, systems and subsystems.

The presentations were well received, and Kong closed the seminar with an expression of thanks and appreciation for the hard work and willingness of the presenters to share their knowledge and experience.

Concluding Thoughts Lift Expo Korea 2014 and the

accompanying International Seminar on Lift Safety were very well organized by KESI. The quality of both was excellent. The expo was well attended by both domestic and international visitors. The overall quality of the exhibits, technical presentations and general organization was first class, and the emphasis on education and innovation augers well for the future of the South Korean elevator industry.

System Analysis and Architecture Methodologies to Drive Innovative Electrical Systems

This paper was presented at Paris 2014, the International Congress on Vertical Transportation Technologies, and first published in IAEE book Elevator Technology 20, edited by A. Lustig. It is a reprint with permission from the International Association of Elevator Engineers

(website: www.elevcon.com). This paper is an exact reprint and has not been edited by ELEVATOR WORLD.

Key Words: Electrical, system, architecture, safety, battery, high-rise

ABSTRACTWhen requirements, constraints, or customer

expectations change, it can have a substantial impact on the desired elevator electrical system configuration. These changes could be a result of global or regional trends (e.g. environmental sensitivity), new fundamental system requirements (e.g. super high rise buildings), code (e.g. Programmable Electronic Safety), or technology advancement. By proper use of system analysis and architecture methodologies, innovative electrical system designs can be achieved that meet and exceed customer expectations.

The results of this process will be illustrated through several case studies.1) Super high rise electrical system2) Optimized machine-roomless architecture3) Battery operated elevator

1. INTRODUCTIONThe electrical system architecture of an

elevator product, once established, typically does not change in a rapid manner. As

requirements and customer needs evolve over time, the traditional approach is to introduce these changes in an incremental manner to meet new market demands.

While this “bottoms-up” approach is low risk and minimizes interface changes, the resulting electrical system architectures and products tend to be suboptimal.

The alternative method is to architect the electrical system using a “top-down” approach. While this approach results in products with significantly increased values to the customer, it requires a more structured and analytical process for architecting the system.

Subsequent sections of this paper will give a synopsis of methods and tools useful to the electrical system architecting process. In addition, three resulting elevator electrical systems will be examined in detail as case studies.

2. METHODS AND TOOLSThere are many structured methodologies

and tools that exist to assist in the creation of a desired architecture. Fundamentally, these methodologies espouse a systematic approach over an empirical approach of design. Some of the key steps of these methodologies are:

♦ Understanding of needs from important stakeholders- Riding public- Building owners- General contractors- Code authorities

♦ Identify Functional Requirements from customer needs

Continued

50 ELEVATOR WORLD India • 2nd Quarter 2015 •

♦ Functional Decomposition for identifying more detailed functional needs of the system

♦ Functional Synthesis to group functions together based on a given criteria

♦ Functional to Physical Mapping to allocate functions to physical entitiesA central idea in the above approach is

to think functionally when designing products (Suh 2001). This will help to transform the customer needs into a set of specifications, or functional requirements. The Functional Requirements are “what we want to achieve”, and the act of design is to map these to design parameters in the physical domain (“how will we achieve it”).

Another salient feature of design methodologies is that they are principle-based. That is, general principles or axioms exist that can be applied to design good architectures. An example of this is the Independence Axiom and Information Axiom (Suh 2001). The Independence Axiom states that the design solution must maintain the independence of the functional requirements. A design parameter in the physical domain satisfying one functional requirement cannot affect another functional requirement.

The Information Axiom states that information content of the design should be minimized. Another way to look at this axiom, as applied to the functional synthesis step above, is to group functions together in such a way that the interface with other function groupings is minimized. For multiple designs that satisfy the Independence Axiom, the one that also satisfies the Information Axiom is considered the best design.

The process of functional to physical mapping should also take into

consideration additional physical requirements of the system, such as available space, component access requirements, etc. As this process is being accomplished, there are often additional functions that are found to be required in order to meet the system objective.

For example, it is common in an elevator electrical system to have functionally related items (such as elevator demand fixtures and the dispatcher) required to be in physically different locations. There are then additional functional requirements for additional communication and power connections.

The methods described above are augmented by the use of various computer-based tools in analysis and modeling. As illustrated in the case of Super High Rise Electrical System, modeling is necessary to evaluate system performance because of the radical change in communication architecture of the electrical system. Additionally, building physical prototype of the full scale system is not feasible due to the large number of nodes

3. CASE STUDIES3.1 Super High Rise Electrical System

3.1.1 ChallengeIn high rise elevator systems, the

magnitude of the complexity of the electrical system is very high. The combination of the increased group size, increased rise/number of floors, and speed pose significant challenges, especially as the height of the world’s tallest buildings continues to increase. Some of these challenges are:

♦ Weight and associated system impact of the traveling cable

♦ Number of nodes and total length of communication to hall fixtures and safety devices (e.g. door locks)

♦ Complexity of maintenance and service with size and scope of entire system

3.1.2 Technical ApproachIn traditional elevator electrical

systems, discrete interfaces are still the predominant method of signaling, especially if the information is safety-related. Recent advances in elevator code (Programmable Electronic Safety) and technology (low cost bus communication interface) have allowed for the implementation of a CAN bus-based architecture to eliminate discrete wires used for safety-related signals. While this approach has advantages in solving some of the challenges listed above, the bus-based architecture has potential impact on signal delay and system performance due to shared processing and communication resources.

Figure 1 shows a subset of the bus structure used to transmit both safety and non-safety related messages within the electrical system. The Safety Interface Board at the elevator car collects and processes all the discrete safety-related signals on the car and transmits them to the Safety Subsystem in the Controller. The Safety Subsystem in the Controller qualifies all the safety related signals before sending them to all the other modules.

All the other non-safety modules, such as the load weighing and controller also communicate over the same CAN bus. In order to successfully deploy such an electrical system solution, it is critical to be able to assess the effect of transmitting both safety and non-safety related messages on the same physical bus.

3.1.3 Critical AnalysisA framework for analyzing and

exploring communication system architecture was developed to assess critical parameter performance of the High Rise Electrical System (Ferrari 2012). The framework consists of an event based simulation environment developed using SystemC, libraries of hardware and software communication components, tools to import application model from MatLab®, and a means to define and configure system topology.

The model topology of the Car CAN bus and Drive CAN bus is illustrated in Figure 2. Each module contains a Figure 1. Bus Structure

collection of functional elements representing the application behavior (FUNC_NODE), CAN Stack (CAN_Stack), CAN Driver (CAN_Driver), and CAN controller hardware (CAN_Controller). In addition to the individual modules, each CAN bus is also modelled as a functional element and the connections to the CAN bus from each module is defined by the user. Other parameters defined prior to the execution of the model includes CAN bus speed, input stimuli (car calls), message arrival rate, and message dead line.

The modeling framework allows for a flexible way to explore different system architecture configurations and network topologies. Simulation of actual elevator bus messages allows for a quantitative evaluation of architecture decisions. Furthermore, the limit of the system can be assessed by modeling increasing car speed and building rise (longer bus length). Message arrival rates are increased with increasing car speed resulting in higher bus utilization.

During initial development, the simulation showed potential issues with queue overflow and dropped messages; these issues were then confirmed with lab data. Subsequent modifications to the configuration of the messaging framework that solved these issues were then made and evaluated by using this same modeling framework and verified through lab data.

3.1.4 Customer BenefitsBy having safety functions implemented

in software and using a network topology

for communication of both safety and non-safety related information, many benefits were realized. The significant reduction in discrete wiring allowed for lower traveling cable weight, which has many beneficial system impacts including reduced propulsion power and the resulting higher system energy efficiency. The higher reliability components used in a solid state safety chain improves system availability. Additional functionality was also implemented that made bypassing of devices well controlled. In this system, these “smart jumpers” are implemented via software built to be transient in nature, and therefore not possible to be accidently left in place. A modeling framework provided the ability to model and simulate critical performance parameters, which allowed such an electrical system architecture to be effectively designed and delivered with high confidence and reliability.

3.2 Optimized Machine Room-less Architecture

3.2.1 ChallengeMachine room-less elevators are the

major market in Europe for the low and mid- range application. The control architecture in many elevators is still based on the architecture that had been originally designed for elevators with machine room. Although modifications were made to accommodate the additional requirements of machine room-less elevators, the control architecture was not able to keep up with the changes in the requirements customers are demanding today:

♦ No aesthetic impact of the entrances ♦ Increased use of hoistway space ♦ Sensitivity for power consumption ♦ Capability in black-out situation

resided in the control cabinet inside the

machine room have been distributed within the hoistway and one of the entrances for their application in a machine room-less elevator.

This has led to several points that were identified as major obstacles to match the control architecture with the changed customer requirements.

♦ The signal transmission is done with a mix of different channels and topologies

♦ The former central power supply is split into various transformation points.A back-up power supply for emergency

and rescue operation in case of black-out situation has added complexity to the power architecture

3.2.3 Technical SolutionIn order to define an optimized control

architecture, the tools and methods described earlier were applied. The result is a re-allocation of functionalities between the main components of the electrical system. The optimization strategy was focused on two elements:

♦ Simplification of signal architecture ♦ Simplification of power architecture ♦ Optimization of physical location of

functionalityA simple signal architecture was

achieved by Serialization ♦ Replacing discrete signal wires with a

serial bus system ♦ Defining a serial bus topology ♦ Applying the serial bus to all main

components of the control system ♦ Additional benefits by improved

information interchange between the componentsA simple power architecture was

achieved by:

♦ Establishing a central system power supply

♦ Defining a serial bus topology ♦ Inclusion of the back-up battery as part

of the central system power ♦ Additional benefits by higher efficiency

and size reduction Optimizing the physical location of

functionality resulted in relocating some functionality from the controller to the car. This resulted in:

♦ Reduction in signaling requirements in the traveling cable

♦ Reduction in space required in the controller

3.2.4 Customer BenefitsThe resulting benefits are

♦ Minimal aesthetic impact: The service and maintenance devices are assembled in the small door column; a specific control cabinet is not required.

♦ Improved use of the hoistway space: The package of the hoistway equipment is reduced in both volume and depth.

♦ Reduction of standby power consumption: The focus is to achieve VDI 4707 class A (VDI Standard, 2009).

♦ Integration of automatic and manual rescue: Only minor add-on components are required to provide full automatic rescue operation.

3.3 Battery Operated Elevator

3.3.1 ChallengeOver the last years, there was an

increased focus on the impact of power supply stability on elevator operation.

Figure 5 gives an overview of the System Average Interruption Frequency (SAIFI) for selected European countries (CEER, 2014). As can be seen, SAIFI is in the range of 0.3 to 4 (outages per year).

Even if these values seem low, there were and are products available that provide emergency rescue operation for an elevator. These products traditionally use separate systems that are both space consuming and costly. Driven by the customer focus on this topic, automatic rescue functions were integrated into the newest product releases without requiring significant more space for control components. Main enablers for this integrated approach are:

♦ Gearless drives with Permanent Magnet Synchronous Motors

♦ Extended control capabilities by regenerative drives

♦ Standardization of voltages inside the control/drive system

♦ Using the gravity driven car direction for rescue operation

♦ Limited number of rescue runs/year

Figure 4. Optimized Power and Signal Architecture

Figure 5. Unplanned Interruptions (SAIFI) for selected European countries Continued

56 ELEVATOR WORLD India • 2nd Quarter 2015 •

In other regions, especially in emerging countries, the situation of power supply stability is quite different.

Figure 6 shows data gathered from Otis Field engineers for different regions in India. Even though the study is experiential, it clearly shows some significant differences from the European data.

♦ Power outages in this graph are per day instead of per year ♦ Most areas have single digit power outages per day

3.3.2 Technical SolutionIn order to provide a solution to the increased needs for power

quality concern, a different approach was utilized. Instead of continuing to incrementally improve the battery supported elevator (i.e. Automatic Rescue Operation), the desired architecture is a fully battery driven elevator (i.e. seamless operation).

While this architecture has several challenges such as the compromise between battery voltage level and motor voltage required for driving the elevator, there are many customer benefits that result.

♦ Autonomous, seamless operation in power outage ♦ Single phase supply ♦ Peak shaving (only average power from grid) ♦ Compatible to alternative energy sources

These features make this battery driven elevator an appropriate candidate to fulfill customer expectations in areas with very unstable power grid conditions. Single phase supply and peak shaving also provide cost advantage in some areas compared to standard 3-phase elevators.

In addition, extending the battery driven elevator to use alternative energy sources such as solar cells or windmills is very simple, since energy storage and management capability are already included in the product.

4. CONCLUSIONSBy proper use of system analysis and architecture

methodologies, innovative electrical system designs can be achieved that meet and exceed customer expectations. Based upon the challenges being addressed, there are often fundamentally different solutions required.

Figure 6. Power Outages per Day in India

This has been shown in several case studies, ranging from super high rise elevators, low rise machine room-less elevators, and battery powered elevators. By continuing to use these analysis and architecture methodologies, future requirements, constraints, and customer needs will continue to be successfully addressed.

Building on a policy of innovation and outstanding service, Sharp Engineers is preparing to offer its elevator components to a wider market. The company was launched as an engineering fabrication business by Mukesh and Babubhai Patel nearly 34 years ago. It produced light machinery, such as winding and power loom machines, for India. Between 1981 and 1990, such products were part of a booming business. In 1991, the Patels added chemical and paint machinery, such as dryers and treadmills.

In 1991, as India’s fortunes and economic opportunity grew, increased real-estate investment drove demand for elevator components. The time was ripe for the elevator industry to take center stage and for India to experience growth as it never had before.

As India’s economy grew, global brands entered the market. The elevator industry also took some hesitant steps as newer brands were introduced and fabricators geared up to explore

a new arena: elevator components. Mukesh Patel remembers:

“In 1994, we started producing below-traction (BT) machines for the elevator industry. During this time, there were very few companies producing BT machines. We decided to take another route into the industry. So, along with manufacturing components, we started doing R&D to explore what we could offer new to customers to differentiate ourselves from competitors and gain more traction in the market.” The result was the launch of SL Series drives.

Increasing competition was pushing for something even more original and innovative, so in 2001, Sharp launched its upper-traction machine CAULDRON. The product grabbed attention and became well known, Mukesh Patel states. There were challenges to be met. Mukesh Patel says that after the launch of CAULDRON, the company responded to these challenges with hard work, cooperation and the ability to adapt to changing market needs.

After 2008, a number of foreign companies entered the market, bringing with them immense competition. Sharp Engineers held fast to its policy of innovation, hard work and

strength to succeed. Today, the company has the highest market share in India for elevator traction machines and successfully exports its products to more than 20 countries.

The growth of Sharp may be traced to the launch of the popular CAL-125 model in 2001. Developed by Technical Director Amit Patel as part of the CAULDRON line, it is a traction machine suitable for elevators with a capacity of up to 26 passengers. After successfully selling the CAULDRON series, Amit Patel developed MP-61, BLP-52, SIDERON, MM-79, BISON and, in 2012, the GEARLESS series, in response to market demand. He observes: “These have a huge demand in the international, as well as Indian, markets, because they are versatile, 3D-mounting machines with an extremely user-friendly installation process.”

Mukesh Patel led a successful effort to educate the Indian market about CAULDRON, ensuring it found acceptance and popularity. “Of course,” he says, “I can attribute all our success and growth to our entire team — our employees, suppliers and customers — who worked with us. It is their valuable support that has made our success possible.”

Mukesh Patel feels the company’s best product to date is the CAL-125R1, a variable-voltage variable-frequency (VVVF), six-passenger, 0.65-mps, Conformité Européenne (CE)- and Canadian Standards Association (CSA)- certified drive that is successfully running in more than 75,000 installations across India. Internationally, he says, the SIDERON AC-2/VVVF, six-passenger, 1-mps, CE- and CSA-certified drive is popular.

Additional products of which the company is proud include the: ♦ SEG-10 six-passenger, 1-mps gearless drive, a CE- and CSA-

certified machine that is environmentally friendly and boasts low power consumption

♦ 300-mm, CE-certified overspeed governor designed according to EN 81 and with CE certification from TÜV SÜDSharp Engineers aims to stay focused on providing the best

possible new technology, service and support to its customers. Mukesh Patel states:

“Since 20% of our sales are in the international market, we are planning to establish an export-oriented unit in the next two years and become a part of the “MAKE IN INDIA” campaign, which is driven by Shri Narendra Modi, honorable prime minister of India.” With distributors in New Delhi, Mumbai, Hyderabad,

Vijayawada, Avishakhapatnam, Bangalore, Kolkata and Pune, Sharp Engineers feels business prospects are strong. 🌐

Natural Disasters

Voltage SagsHow these phenomena affect the elevator industry and steps that can be taken to mitigate their effects

Your authors were first inspired to look into the issue of voltage sags in 2004 after a serious sag due to a heavy thunderstorm in Hong Kong caused more than 50 elevators to halt, trapping quite a number of passengers. Normally, when an elevator fails to operate and its passengers are trapped, building management calls the maintenance contractor first. And, if there is any potential passenger injury, help from the police, then firefighters is sought. This practice is, perhaps, usual anywhere around the world. But, if we think about a situation in which hundreds of elevators are tripped at the same time due to an electric power problem (voltage sags and blackouts being two possible causes to consider), is it likely that adequate support from both maintenance contractors and firemen is available to rescue thousands of trapped passengers? Furthermore, after a series of voltage sags followed by immediate elevator stoppages somewhere along the hoistway in Hong Kong from 2004 to 2006, debate began on who should bear the responsibility: the electric utility, elevator manufacturer and/or maintenance contractor?

Power quality issues are of increasing concern, because devices such as computerized controls, variable-speed drives, automated intelligent smart devices and sensors are sensitive to fluctuation in supply voltage. Users and manufacturers are usually not aware of the impact of voltage sags when they purchase or produce new equipment. Once the equipment is in operation and suffers from stoppage due to voltage sags, the utility is usually criticized for poor power quality. This is the reason why users demand zero voltage fluctuations from a utility,

rather than expecting the manufacturer to provide electrical equipment with appropriate power-quality compatibility.

Electric Power Quality and Voltage Sags

Voltage sags caused by adverse weather conditions could be unavoidable. The term “voltage sag” is used by the trade in the U.S., while “voltage dip” is widely used in Europe. One of the best references to the issue of electric power quality is the Institute of Electrical and Electronics Engineers (IEEE) Standard 1159-2009 on the recommended practice for monitoring electric power quality. According to the standard, the term “power quality” refers to a wide variety of electromagnetic phenomena that characterize the voltage and current at a given time and at a given location on the power system. The recent increase in attention to electric power quality has been due to the popularity of active (nonlinear) power electronic devices, such as rectifiers or choppers of high power rating in which the three phases are not equally consumed and/or the current waveform is no longer sinusoidal. The standard makes use of an electromagnetic compatibility (EMC) approach to describe power-quality phenomena.

According to the International Electro-technical Commission (IEC), EMC describes the ability of electronic and electrical systems or components to work correctly when they are close together. In practice, this means that the electromagnetic disturbances to others from each item of equipment must be limited and that each item must have an adequate level of immunity to the disturbances in its environment. The ultimate target is to make sure all equipment

can enjoy a high level of reliability and safety when working together with other equipment.

IEC classifies the principal phenomena that cause electromagnetic disturbances into groups. The “conducted low-frequency phenomena” group is related to harmonics, voltage fluctuations, voltage sags and interruptions, voltage imbalance, power-frequency variations, induced low-frequency voltages, and the existence of DC components in an AC network. While this group usually concerns the elevator industry the most, there are other groups like “radiated low-frequency phenomena” related to magnetic and electric fields, and “conducted high-frequency phenomena” related to induced continuous-wave voltages or currents, unidirectional transients, oscillatory transients, etc.

Such phenomena could be assessed for a steady-state study in accordance with IEC 61000-2-5 by attributes including amplitude, frequency, spectrum, modulation, source impedance, notch depth and notch area. For a non-steady-state study, alternative attributes, such as rate of rise, duration, rate of occurrence and energy potential, are involved.

For example, in the standard, to describe a category of “long duration root-mean-square (rms) variations,” the typical duration of an interruption, undervoltage, overvoltage or current overload is longer than 1 min., while the amplitude of interruption is 0.0 per unit (pu), that of undervoltage is 0.8-0.9 pu, and that of overvoltage is 1.1-1.2 pu. Here, 1.0 pu, being a dimensionless quantity, refers to 100% of the rate value. The duration of power-frequency variations is usually less than 10 s. long, while the amplitude of variation is ±0.1 Hz.

Now, we come to voltage sags. A voltage sag refers to a short duration, usually up to 1 min., when the magnitude of voltage supplied to a system is reduced. The term “swell” is an inverse to sag. In the standard, a category known as “short-duration rms variations” is used to include sags, swells and interruptions. Instantaneous sags (a magnitude from 0.1 to 0.9 pu) and swells (a magnitude from 1.1 to 1.8 pu) have a duration of 0.5-30 cycles (i.e., 0.0083 to 0.5 s. in a 60-Hz system). Momentary interruptions (a magnitude less than 0.1 pu) have a duration from 30 cycles (0.5 s.) to 3 s. Momentary sags (a magnitude from 0.1 to 0.9 pu) and swells (a magnitude from 1.1 to 1.4 pu) have durations from 30 cycles (0.5 s.) to 3 s. Temporary interruptions (a magnitude less than 0.1 pu), sags (a magnitude from 0.1 to 0.9 pu) and swells (a magnitude from 1.1 to 1.2 pu) have durations from longer than 3 s. to 1 min.

Voltage sag is only one issue within the whole family of electric-power-quality problems, which also includes:

♦ Sudden but very short increases in voltage, which are usually called “spikes,” “impulses” or “surges”

♦ Undervoltages, sometimes called “brownouts,” that cause dimming of incandescent lamp bulbs (different from “blackouts” [no voltage])

♦ Harmonics, i.e., the existence of high-frequency components bearing frequencies that are multiples of the fundamental, such as 50 Hz or 60 Hz, that may lead to interference and low energy efficiencyA voltage sag is not considered a power failure or interruption,

which often only lasts up to 0.2 s., after which normal power supply will be restored. (Note that the formal definition, however, allows

a prolonged existence up to 0.5 s. for an instantaneous sag.) There could be many causes of such an event, most of which are associated with bad weather conditions. During a thunderstorm, lightning strikes often hit the overhead transmission lines responsible for the transmission of electric power from the generating plant to substations. Such overhead lines are usually found in the suburbs, across mountain ridges or on plains, where they are the tallest nearby objects. Although the tip of transmission towers is connected by an earthed shielded or guarded wire for protection, while the transmission voltage (say, at 400-800 kV) is a bit closer to the voltage of the lightning strikes, there are still chances of the overhead lines being hit by them.

After hitting a phase conductor, the lightning strike continues its way to the ground, either via the tower itself or immediately downward (Figure 1). In this way, a short voltage sag is caused (Figure 2), because the path of the lightning strike from the phase conductor to the ground is virtually an intermittent short-circuit. In addition to third-party interference due to engineering projects, external interferences, such as plants, animals and flying objects could also cause voltage sags.

At the same time, overvoltages originated by lightning are major causes of flashovers on overhead power lines. These may cause permanent or short interruptions, as well as voltage sags on distribution networks. Additionally, lightning-originated surges

can also damage the power components and electronic devices connected to these networks.

Risks of Voltage Sags or BlackoutsWhen your authors investigated the aforementioned incidents

in Hong Kong, the first stage involved a brainstorming session with representatives from the local elevator industry. Afterward, actual site tests with an artificial voltage-sag generator were conducted. Finally, some proposed solutions were tested onsite.

It was found that most practical voltage sags are within a period of 0.2 s. Their impact could be on the elevator controllers, power electronic drives, doors and safety circuits. Out of these, the motor drives are mostly susceptible. This is because, upon a sudden voltage sag, the drive could automatically boost the transient current supplied to the motor, thus probably damaging the electronic circuitry of the drive. Even if the circuitry remains healthy, there is still a chance the drive and/or controller may be tripped due to current overload. Once tripping occurs, the brake would be applied, and the elevator car would stop somewhere along the hoistway with passengers trapped inside. (Here, “tripping” refers to the electric circuit and has nothing to do with the safety devices mandatorily listed in the safety codes.) There would then be the question of whether these electronic devices could be cold booted automatically. If yes, the car could resume normal operation after a while and bring the passengers to a safety stop.

It was found that during the tripping, some controllers lost record of the current position of the elevator car. After restoration to normal operation, the car would be driven slowly to search for some position indicator along the hoistway. If nothing could be found within 45-60 s., the whole system would be tripped again, resulting in passenger entrapment.

There are several concerns here, from the passengers’ point of view. First, the car experiences sudden braking without any smooth deceleration stage right after the tripping, possibly resulting in personal injury. Second, whether the controller could be reset to send the passengers to a safe landing is still unknown. According to ASME 17.1 and EN 81-1, during emergency braking, under a fully loaded down condition, the deceleration upon braking must not be more than 1 g (9.8 mps2/32 fps2). To a normal and healthy person, such deceleration is not critical, though normal braking deceleration is well below that value. However, to an elderly or unhealthy passenger, his or her weight being suddenly doubled when traveling downward may cause a fall, leading to injury. Even if the car is moving upward, the reaction on the soles of passengers’ feet from the car floor is suddenly reduced significantly during emergency deceleration, which can also cause a fall. Although an elevator emergency braking action is still considered safe, it is totally undesirable.

Another concern is related to passenger trapping. If the controller could not be cold booted or reset to work again, or cannot drive the car to update its current position within 45-60 s. under maintenance speed, the car could continue to stop (or stop again), with passengers needing to wait for rescue. Passenger entrapment, though still considered safe in the elevator industry, can jeopardize passengers, whether due to their age, poor health or propensity to self evacuate. Some passengers may start to feel uneasy after being trapped in an enclosed space for as short as 10

min. This concern is not only a possible result of voltage sag, but a certain result of a blackout.

The reliability of electric power plants is getting higher and higher due to the advancement of technology. Accordingly, some citizens living in metropolitan areas have almost forgotten the risk of blackout. When hundreds of elevators suddenly stop with thousands of passengers trapped within a district, both maintenance contractors and firemen cannot attend all the sites to rescue the passengers on time.

SolutionsFortunately, the probability of a lightning strike directly hitting

a phase wire of an overhead transmission line and causing a voltage sag is not high. Moreover, based on our survey in Hong Kong, most modern elevator controllers can self reset after tripping due to a voltage sag. Also, our test found that under a less serious voltage sag (say, with a voltage of at least 0.8 pu), most elevator controllers and drives are unaffected. While voltage sags due to lightning strikes and blackouts cannot be prevented from happening, something has to be done to mitigate their impact for the sake of passenger safety, health and comfort.

A ride-through device could be installed to tackle the sudden stoppage of the elevator car during a short voltage sag of up to 0.2 s. One such device is a DC backup type able to maintain a more-or-less stable DC bus inside the drive during a voltage sag by temporarily boosting the supply voltage and transferring power from a built-in capacitor inside the device. However, this solution is only applicable to drives with a DC bus, such as a pulse-width-modulated rectifier inverter drive.

Ride-through devices have been installed in escalators in Hong Kong since 2005. According to the region’s Code of Practice on the Design and Construction of Lifts and Escalators Addendum to Amendment No. 8 of 2000 Edition, the braking system of an escalator automatically starts to operate at a lapse of 0.2 s. of a continuous supply voltage sag of more than 10% of the supply voltage, or at a voltage sag exceeding 60% of the supply voltage (without any delay), if the escalator is equipped with such a device to sustain operation during power-supply voltage sags. A sudden stoppage of an escalator could result in the injury of tens of passengers riding on it, which explains why the authority in Hong Kong allows such installation on escalators. Having said that, the authority has had huge concerns about the use of such a device on elevators. The concerns are due to the lack of international standards and product choices in the industry. A delay of braking in 0.2 s. seems to be another concern. Is such a delay that critical?

Whenever something abnormal happens during the operation of an elevator, the brake must be applied on time. Traditionally, the brake is applied by means of a spring when the DC power is removed from the solenoid. Recently, active brake control has been introduced to both elevators and escalators by various researchers and manufacturers.[1 & 2] By using active or intelligent braking, the deceleration rate is under moderate control so that no slipping between the sheave and hoisting ropes is guaranteed. Moreover, if the conventional mechanical brake is used only as a parking brake here, lower wear rates can be sustained. This technology has been applied to automobiles and trains for decades. According to EN 81-1, deceleration under emergency braking

must be 0.2-1 g. It is assumed here that the rated speed of an elevator is 5 mps and the deceleration rate is kept constant at 0.2 g (1.96 mps2). The time needed to bring the car to a stop is given by speed/deceleration = 2.55 s. The delay due to the intervention of the ride-through device only accounts for 8% of the whole action.

Besides the impact on the drive, the controller is also very sensitive to voltage sags. Though it is impractical to install an uninterruptible power supply (UPS) to the whole elevator system, with a view to tens of kilowatts, it is not an unreasonable investment to only back up the electronic controller cards by using a UPS to ensure no tripping due to a voltage sag (and, hence, no resetting) is necessary.

Once the elevator suddenly stops (irrespective of either a voltage sag or blackout), the most important strategy is to bring all trapped passengers to the nearest safe landing to let them leave the car. This could be done by the installation of an emergency rescuing device. This device temporarily takes over the controller, drive and brake of the elevator system once tripping occurs. It then checks which side is heavier (i.e., the car side or counterweight side). If the car side is heavier, the device lowers the car to the nearest landing, opens the car/landing doors, closes them afterward and parks the car at this landing until the maintenance technicians arrive onsite to reset everything. A similar set of operational procedures exists if the car side is lighter, but the car is then raised up to the closest safe landing. In either case, a built-in battery ensures the emergency rescuing device works normally long enough to rescue all trapped passengers. From the authors’

point of view, emergency rescuing devices are particularly useful in tackling both voltage sags and blackouts. They have been installed on a large scale – for example, all elevators serving public-housing estates in Singapore are equipped with them.

Finally, even if passengers are trapped under such an emergency condition, it is important that their summons for help be made known. In commercial or industrial buildings unmanned during weekends, there have been incidents in which a trapped passenger had been left alone for hours before being rescued. A “remote alarming, monitoring and communication” system may be the last resort by which to effectively rescue trapped passengers. The whole Chapter 14 of CIBSE Guide D: Transportation Systems in Buildings, 2010 Edition discusses the reasons for remote alarms and monitoring, the functions of it, the information available from the system and its interface with the building management system. By this system, trapped passengers are able to make a service center aware of them and even communicate with the center’s personnel.

Conclusion Some elevators are sensitive to power-quality issues, and they

stop operating, thus trapping passengers. Different ways to tackle this problem have been discussed, including ride-through devices, UPSes, emergency rescuing devices and remote alarming, monitoring and communication systems. It is hoped that readers do not forget the risks of power-quality issues and prepare for them before a related emergency occurs.References[1] K. Seaborne, L. Al-Sharif and D.

Discovery Bay North Wireless door systems help overcome the logistical challenges of a truly international project in Lantau Island, Hong Kong, China.

Lantau Island is the largest island in Hong Kong, located at the mouth of the Pearl River. Administratively,

most of Lantau Island is part of the Islands District of Hong Kong. Originally the site of fishing villages, the

island has been developed in recent years with the construction of Tung Chung New Town on its northwestern

coast and the completion of several major infrastructure projects next to the Discovery Bay Resort, including

Lantau Link (1997), Hong Kong International Airport (1998), Hong Kong Disneyland (2005) and Ngong Ping

360 (2006).

Discovery Bay covers a land area of 649 ha and is a fully integrated resort-style residential project.

Approximately 18,000 people (with more than 50% non Chinese) reside in its multicultural community. All

aspects of the project, including infrastructure, city planning and transportation connecting Discovery Bay with

central Hong Kong, were developed by Hong Kong Resort International Ltd. (HKRI) from scratch. At present,

24-hr. ferries and buses, plus a privately built tunnel, provide Discovery Bay residents with convenient

transportation services. Fifteen phases of residential development had been completed as of May 2014, and

HKRI continues to develop Discovery Bay’s land bank into residential and commercial facilities.

Since its development in the late 1970s, Discovery Bay has been one of the largest resort-style residential communities in the region and is widely acknowledged as a pioneering model for sustainable integrated residential development in Asia.

ElevatorsTwo inclined lifts were installed to enable the residents of the newly developed apartment

buildings to access the shopping area of Discovery Bay North Plaza. With a 60-m-long structure rising to the height of a 10-story building, they are the latest landmark in Discovery Bay, boasting a stunning panoramic view of Yi Pak Bay.

Support Structure

The elevated rail support structure on the lower bearing is fixed, and the inclined support blocks are mounted for longitudinal displacement. The cross-barred support in the transverse support takes the horizontal forces (due to wind load on the car).

Drive System

A general concern when designing inclined elevators is the ropes. As opposed to those of a vertical lift, the ropes always have to receive some sort of guidance and support. To reduce extra noise and wear, this support mostly consists of rollers, which – especially in great numbers – create a considerable amount of additional noise. Consequently, the length of the ropes should be as short as possible.

orthUnfortunately, the design of the upper platform at

Discovery Bay North could not make enough space available to accommodate the lift machines. But, the machine in the lower platform would – for a traditional traction elevator – result in four sets of ropes on each track: two for the cars and two for the counterweights, one going up, one going down.

A loop system was designed to reduce the number to two sets (Figure 1). In that case, the car is connected via ropes on both sides to the counterweight. At the upper side is a pulley to deflect the ropes, and on the lower side is the sheave. To compensate for the change in load and still achieve traction, the machine slides on its frame along T-shaped guide rails and is tensioned by a 4-mT tensioning weight.

LogisticsAs the construction site encircled a very small

area and the elevator parts (especially the support structure) with its long, massive H-shaped beams consisted of heavy, bulky material, logistical problems were among the major ones to be solved. A mobile crane was placed in the tight, confined area to move complete sections of guide rails combined with H-shaped beams up the slope. A very tight plan for all participating trades was developed to make a continuous workflow possible.

Door SystemUsually, the cabin and landing doors of an inclined elevator are coupled with a mechanical system that allows

the car doors to jointly open the landing doors at every floor. This system envisages a motor and a coupling skate for the cabin door, whereas the landing doors are engaged through their own lock.

The installed wireless system allows the control panel to check both cabin and landing doors when they face each other. It allows communication between cabin and landing doors, even though they operate with independent motorization and mechanics, and the control-panel signal arrives only to the cabin door (as with traditional systems). Once the signal arrives, the cabin door itself transmits it to the landing door, which simultaneously opens. This is possible thanks to two peripheral small-scale and weatherproof infrared receiver/transmitter systems for the data exchange. 🌐

Codes & Standards

by Louis Bialy Louis Bialy and Associates, USA

The Global Relevance of Performance- Based Codes

This paper was presented at Paris 2014, the International Congress on Vertical Transportation Technologies, and first published in IAEE book Elevator Technology 20, edited by A. Lustig. It is a reprint with permission from the International Association of Elevator Engineers

(website: www.elevcon.com). This paper is an exact reprint and has not been edited by ELEVATOR WORLD.

Key Words: Elevator, safety, performance, codes, performance based codes

Abstract As the world economy continues to grow

more global in nature, the demand for innovative products accelerates. The competition in ideas enhances consumer value in terms of safety, quality and performance. The Machinery and Lifts Directives spawned a wave of innovation in the elevator industry and inspired ISO to create documents and processes that could be widely adopted in order to support innovation with safety. The value of this approach has been recognized in several parts of the world and adoption and utilization of this important process is gaining momentum. This paper elaborates the Performance Based approach and describes how it is being embraced in various parts of the world.

1. IntroductionIt is apparent to travelers around the world

that so much of what they have become used to in their home environment is also available wherever they go. This observation is one of the many consequences of increasing globalization. Moreover there is a growing symbiosis between the availability of familiar goods and services

and the expectation that similar levels of quality will be maintained. This expectation is particularly relevant in the area of safety. The transportation industry is a good example of this in that people expect the same level of safety in motor vehicles, rail transport, air transport, etc. as they would enjoy in their home base. The elevator industry has demonstrated a very high level of safety around the world particularly considering the volume of passengers transported on a daily basis. Indeed the expectation of the safety of elevators has become so ingrained in society that any accidents or mishaps receive broad attention.

There are many reasons for the globalization of the world’s economy and it is beyond the scope of this paper to elaborate on all of them. However it should be noted that the increasing pace of communication on a global scale is a major causal factor. Thus when something is available in one market, it is quickly discovered in other markets and spontaneous demand drives its rapid deployment. While, to some extent, this leads to the commoditization of world markets, it also encourages innovation. Thus consumers are always seeking higher value options to meet their needs and providers respond with innovative solutions. The pace of innovation is accelerated by competition as each provider strives to remain relevant in the marketplace of ideas and solutions.

2. The Role of StandardsStandards fulfill several important functions

in products and processes in the elevator industry. Important examples are design standards which ensure that elevators will be compatible with building structures. Examples

include the ISO 4190 series of standards which address elevator car and entrance dimensions, hoistway dimensions, duty loads and standard rated speeds. Sizes of control buttons and their locations in the car or landing are also addressed by this series of standards. Measurement standards to ensure a common basis for comparison such as energy consumption measurement standards and ride quality measurement standards have also been developed under the ISO umbrella.

Principle amongst elevator standards are Safety Codes that address public safety. Prescriptive Safety Codes such as ASME A17.1/CSA B44; CEN EN 81; SAC GB 7588 and the Building Standard Law of Japan (BSLJ) have served the cause of public safety very well for decades. Prescriptive Codes are usually the result of a thorough, comprehensive consensus building process. Such a process requires input from balanced committees comprising different interest groups and a systematic public review procedure. The end result is a high level of safety; however the process by its very nature tends to be slow and deliberate.

This leads to a difficult challenge in addressing the demand for innovative products. Indeed, if the only way to introduce an innovative produce was to change the prescriptive Code; by the time the process was complete the product would no longer be novel. Prescriptive Codes were intended to assure public safety not to restrict innovation.

This is demonstrated by earlier versions of Codes such as A17.1/B44 which recognized that the Code cannot cover all situations, and that alternative technology should be allowed by the Authorities Having Jurisdiction (AHJs), provided that it could be demonstrated that safety equivalent to that required by the Code has been achieved. The Code however did not provide a uniform, structured process for effecting this option. The situation in North America was greatly affected by the advent of the Machinery Directive and Lifts Directive in the EU.

3. The Global Effects of EU DirectivesThe objective of introducing Health and Safety Directives in the

EU was to discourage national standards from becoming technical barriers to trade. Indeed it was recognized at an early stage that free trade agreements would not be effective if differing national standards could be used to prevent products from entering any particular market.

Thus Directives containing Essential Health and Safety Requirements (EHSRs) as well as a Conformity Assessment process were developed under the European Commission (EC) and ultimately transposed into national law by each member country of the EU. The Machinery Directive applies to escalators as well as elevators while the Lifts Directive provides particular requirements for elevators.

Harmonized standards, without national deviations, such as CEN EN 81 and CEN EN 115 were developed to provide a presumption of conformity with the Machinery and Lifts Directives. Thus the terms of the directives could be met by fulfilling the EHSRs directly or by meeting the requirements of the harmonized standards.

In order to ensure conformity assessment with the Directives, competent organizations were accredited in each country in the

EU and notified to the EC. These organizations are referred to as Notified Bodies.

The effects of the Directives in the EU have been dramatic. Uniform standards have been instrumental in improving and harmonizing levels of safety. Moreover the economic effects of uniform standards have been significant. A further result of the Directives has been a major boost in innovative products.

The EHSRs of the Directives are expressed, for the most part, in performance language, thus allowing many different solutions to safety issues. A process of verifying safety using Risk Assessment, and the subsequent validation by the Conformity Assessment process ensures safety while allowing innovation.

As new innovative products emerged in the EU, the demand for such products occurred in markets outside of Europe. The process available under the Directives was not applicable in non-European markets and this became a source of great difficulty.

4. ISO InitiativesIn order to address this need for innovation with safety on a

global scale, the ISO 22559 series of documents was created. These documents provide Global Essential Safety Requirements (GESRs); Global Safety Parameters (GSPs); and requirements for Global Conformity Assessment Bodies (GCABs).

Moreover the ISO 14798 Risk Assessment Methodology provides a tool for ensuring that the proposed design is safe and that all risks have been identified and sufficiently mitigated.

ISO 22559-1 has been updated and is in the process of being published. The update includes clarification of several of the GESRs and related explanations and an annex has been incorporated to review similarities and differences between the ISO GESRs and the EHSRs of the Machinery and Lifts Directives.

This annex is particularly useful for users who wish to ensure that innovative products that meet the requirements of the ISO 22559 series of documents will also satisfy the Machinery and Lifts Directives.

In principle, local adoption and enforcement of the ISO 22559 series of documents, as a parallel method of establishing safety to applicable prescriptive Codes, provides the same opportunity globally that is currently available in the EU.

5. The North American ApproachNorth America has long been recognized as an area of

technological innovation and creativity. Consistent with this ethos, when innovative elevator products became available in Europe, a strong demand rapidly emerged in North America.

The process described in Section 2 above was extensively utilized to deploy such products in North America. This proved to be a very difficult procedure due to the fact that a uniform structured protocol was not available. Thus some authorities required extensive documentation and verification while others preferred minimal information in order to permit identical products. Moreover, many Enforcing Authorities did not have the resources to effectively evaluate the documentation provided, and this caused major challenges for them. The situation also created great difficulties for the manufacturers and providers of innovative equipment, as the resources needed to handle so many differing demands from Enforcing Authorities were severely strained.

It became clear that a process analogous to that available in Europe was needed in North America. This gave rise to the development of the ASME A17.7/CSA B44.7 Performance Based Code. This Code is based on the ISO 22559 series of documents and the ISO 14798 Risk Assessment Methodology. It includes Safety Parameters consistent with existing prescriptive Codes and describes a process for using the A17.7/B44.7 Code to establish safety. Moreover, a process was developed to establish Accredited Elevator/Escalator Certification Organizations (AECOs). These organizations are capable of evaluating Code Compliance Documents produced in support of innovative designs, and certifying such designs.

A section was included in the A17.1/B44 prescriptive Code confirming that A17.7/B44.7 is permitted to be used in lieu of A17.1/B44 and, in effect, establishing equivalence between the two Codes. Similar language was included in A17.7/B44.7.

This action on the Code development front provided a structured approach to establishing the safety of innovative products and a consistent method of deployment in North America. Current activity in Performance Based Code development involves the updating of the standard to reflect recent revisions in ISO 22559-1 and the inclusion of GESRs and examples relating to escalators, based on ISO GESRs recently approved for publication.

Code adoption and enforcement in North America is on a jurisdiction by jurisdiction basis. Thus it is important that the various jurisdictions adopt the A17.7/B44.7 Code. While adoption has been rapid and embraced with enthusiasm in some jurisdictions, others have been rather slow to adopt A17.7/B44.7 and have resisted the process. This is unfortunate as the process is of great help to the authorities, particularly those that do not have the internal resources to evaluate innovative designs on the scale required by the market.

Nevertheless, A17.7/B44.7 is steadily gaining credibility, and even many authorities that have not adopted it require an AECO certificate as a prelude to a jurisdictional equivalent safety ruling process. It is reassuring to observe that thousands of elevators have been installed throughout North America utilizing the A17.7/B44.7 process.

6. Action in ChinaIn recent years China has become the largest new equipment

market in the world in the elevator industry. It is anticipated that this situation will continue for many years into the future. China is also a progressive society with an appetite for innovation and state of the art equipment. It is therefore not surprising that China was relatively quick to utilize the ISO 22559 process for innovative equipment.

Understandably, the Chinese process differs from the European approach in that Directives are not applicable in China. Moreover, although there are some similarities, the North American model does not completely fit the Chinese approach.

The process effective in China requires the submitter/manufacturer to develop and verify the design according to ISO 22559-1 including a risk assessment per ISO 14798. Corresponding documentation and relevant design and testing records are to be included as part of a Code Compliance Document. This document

will also contain inspection and field testing information. The Code Compliance Document is then submitted to one of three engineering and testing organizations recognized by the Standardization Administration of The People’s Republic of China, to evaluate innovative technology.

Once the submission has received preliminary approval it is presented to National Technical Committee TC 196 for further review and approval. This committee has representatives from Code Authorities, Engineering and Testing Bodies, Manufacturers and Inspection Authorities. Once approved at this level the submission is directed to the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) for final approval.

While this is a long and complex process it is very thorough and certainly results in a high level of safety. It is encouraging to note that hundreds of thousands of innovative products have been installed and are operating in China.

7. Action in Other CountriesProcesses consistent with that described by ISO 22559-1 and

the Risk Assessment Methodology, ISO 14798 are being used for the deployment of innovative products in many parts of the world even though these documents have not been formally adopted. Adoption of the former has been inhibited by the fact that it was previously published as a Technical Specification rather than an ISO Standard.

This is not unusual, as ISO documents are often published first as Technical Specifications in order to establish their value and gain experience with their use prior to their becoming full ISO standards. The recently revised version of ISO 22559-1 is a full ISO standard ready for broad adoption, or incorporation into local requirements.

8. Future ConsiderationsIt is anticipated that broader adoption of the ISO 22559 series of

documents and ISO 14798 will occur in the future as the demand for innovative products increases. It is also anticipated that some of the more globally active Certification Organizations will become GCABs.

A major step forward would be multi-national recognition of certifications so that an innovative product only needs be certified by one GCAB in one country to be accepted worldwide. This would greatly enhance the availability of safe innovative products and bring added value to all parties.

Inspection

by Wang Weixiong, Liu Yingjie, Wu Xingjun, Wang Xinhua, Xie Chao, Song Yuechao and Li Gang edited by Peng Jie

Innovative Balance Coefficient Testing System for ElevatorsTime, money and manpower can be saved using a new testing method.

Elevators play an important role in vertical transportation to facilitate the daily life of people. With the number of elevators increasing, safety issues are drawing more and more attention from researchers in the elevator industry. Today, almost every elevator is subject to inspection by certificated inspectors as specified by code regulations. Testing the balance coefficient of the elevator under inspection is a key task for inspectors and usually related to the traction capability of the machine. The traditional method to test the balance coefficient is measuring the current, which requires different preset load blocks to be placed in the car for a series of measurements. Then, the car is run with the first load set and the running current is recorded. This is then repeated with the second load set and so on. The balance coefficient is made available after drawing curves and lines based on the measurement records.

The traditional way costs much more time, money and manpower compared with our innovation. This empty-car load-balance coefficient testing system is proposed by means of the definition of “balance coefficient.” The inspector uses the testing system to measure the weights of the empty car and the counterweight, respectively, from which the balance coefficient can be calculated. Preset load blocks are no longer necessary. The system has been tested with elevators on actual jobsites, and its measuring accuracy was at the same level as the traditional method. Your authors hope their system will improve balance coefficient testing procedures in the near future.Background

Elevator safety is a focus of more and more attention from researchers in the industry. As

special equipment, elevator safety equipment requires inspection every year by code regulations. Measurement of the balance coefficient is one of the important inspection tasks to be fulfilled with newly installed elevators. The balance coefficient is related to traction capability of the machine, defined as the ratio of the weight difference between the counterweight and the empty car relating to the rated capacity of the elevator.

Additional weight on the car side may change the balance coefficient and affect the traction capability of the elevator (for example, if users add decorations to the cab). As a result, the heavier car allows the elevator to run under hazardous conditions. It is impossible to carry out a balance coefficient test for every lift in regular inspection practice (as in a yearly inspection) using the traditional test procedure. To overcome the challenge, we have tried testing methods with empty cars. In one, an indirect measurement of the tension on suspension ropes is made (Figure 1a). With that, the weight of the empty car and counterweight can be found by calculation. The method depends on calculations for balance coefficient with relatively rough measurement accuracy.[1]

Another method makes a direct measurement of the weight of the empty car and the counterweight by means of a load sensor (Figure 1b). However, it is difficult to fix the load sensor on the jobsite, so its practical application is limited.[2 & 3]

One more method is proposed by TÜV SÜD: by installing one gripper on the suspension ropes and another gripper in the machine room, the operator manually releases the brake of the traction machine to acquire the balance

coefficient of the elevator. This is easier to carry out, but affixing the gripper in the machine room can pose a great challenge to the operator, and the manual release of the brake also calls for the operator to have sophisticated skills.[3] The improved method your authors propose (Figure 1d) uses two grippers fixed on the suspension ropes, that exert a hydraulic force to make the wire ropes between the grippers slack; then, the load sensor placed between the cylinder and the upper gripper measures the weight of the car and/or counterweight.

System Designs Design Structure Comparisons

There are three design structures proposed for the purpose of testing the elevator balance coefficient. In Figure 2a, the structure is composed of a lower gripper, an upper gripper to be fixed on a suspension rope, a cylinder for lifting the car or the counterweight, a sensor for measuring the weight, and a pulley and a wire rope for transmitting the force. This design structure is easy to manufacture and install, but there are bias loads when lifting the car or the counterweight. In Figure 2b, both the lower and upper grippers are fixed on the suspension ropes, four cylinders are used to lift the car, and two sensors are used to measure the weight. The push-out cylinder pushes the lower gripper up until the suspension ropes

between the lower and upper gripper become slack so that the screen reading shows the weight value of the empty car or counterweight. However, the push-out cylinder requires much more height, versus the pull-in cylinder. In Figure 2c, the pull-in cylinder lifts the load, saving the working height of the device. Hence, it is the most practical of these design structures.

Determination of ParametersThe balance coefficient testing system is designed based on the

structure shown in Figure 2c. The maximum rated load Wmax is set at 3000 kg, the complete unit weighs within 30 kg, the available measurement of suspension-rope diameters range 8-16 mm and the number of suspension wire ropes for measurement range from two to five.

Inner Nylon Pads To prevent the wire ropes from being damaged by the steel

grippers in the test, an inner nylon pad set is attached to the steel gripper to protect the wire ropes. Its strength is verified by finite element method. The final pad dimensions are 100 X 18 X 50 mm (Figure 3). The wire ropes fit within five grooves, which include carved-in notches to increase friction.

Bolt ParametersTo lift the maximum weight Wmax, the

friction force Ff exerted between the inner gripper pads and suspension ropes must be equal or greater than Wmax; then, Ff is calculated with:Ff = 4 X ƒ X Fv = Wmax (Equation 1)

In Equation 1, ƒ is the friction coefficient and Fv is the pre-tightening force of the bolt. After substituting the value ƒ for 0.3 and the value of Wmax for 3000 kg, the least-required Fv is found to be 25 kN. Referring to the “Bolt Pre-tightening Table” in the Mechanical Design Handbook, the 8.8 class M14 bolt is selected for Fv = 52 kN when the pre-tightening torque is 135 Nm.

Cylinder Parameters

Two cylinders are applied to move the lower gripper up, according to the design specifications. To raise the maximum load of Wmax (3000 kg), the piston diameter d and the cylinder’s inner diameter D (both in millimeters) must be determined. A light cylinder type is selected, with its rated pressure p around 5 MPa. Then, both diameter values can be calculated by Equation 2. A cylinder with a dimension of 25 X 15 X 100 mm is preferred.π/4(D2 - d2) X p X 2 > Wmax (Equation 2)

Experiments Calibration

Two force sensors are used in the testing system. Both must be calibrated to ensure their working accuracy. Preset load blocks weighing 500 kg and 1000 kg, respectively, are used for the calibration. Figure 4 shows the calibration site, where one end of the sensor is connected with a hook of crane, while the other end is connected with a preset load block. After the calibration, the sensor’s measurement deviation ranges within +/-0.1% of the full scale.

Next, the complete testing system is calibrated using the 500-kg preset load block (Figure 5a). Due to the additional weight of the cylinders, the lower gripper, the hose and the wire rope, the display value in the screen reads 40 kg more than the 500 kg of the preset load block as shown (Figure 5b). Adjustments were made to compensate for the extra weight inherent to the testing system.

Test on a Typical MRL Elevator with 2:1 Roping A typical machine-room-less (MRL) elevator was used to test

the efficiency and accuracy of the newly developed system for balance coefficient measurement. A lift with a rated capacity of 1000 kg and rated speed of 1.75 mps is chosen for the experiment, which is carried out on the top of the car. At first, the weight of the empty car is measured, with the test device fixed on one side of the suspension ropes (Figure 6a). Then, the piston is manually pulled

out of the pump to raise the lower gripper in order to make the suspension ropes between the upper and lower grippers slack (Figure 6b). The screen should then read 1160 kg, indicating the measured weight of the empty car.

The second step is to measure the weight of the counterweight before and after lifting the counterweight (Figure 6c-d), with slack wire ropes between the upper and lower grippers. The weight of the counterweight reads 1,655 kg. The balance coefficient of this elevator can be calculated from the above measurements, resulting in the value of 0.49. In comparison with the measurement value of 0.48 by the traditional method, the values from the two testing methods highly agree with one another.

Test on a Typical Elevator with 2:1 Roping

A typical elevator with machine room (Figure 7a) was also selected for testing the efficiency and accuracy of the newly developed system. The rated capacity of the lift is 1000 kg, and its rated speed is 1.75 mps. Testing of the counterweight reveals its weight is 1,484 kg. Testing the empty car (Figure 7b) reveals its weight is 1,018 kg. Therefore, the balance coefficient of the lift

a b

Figure 7: Testing the new system on an elevator with machine room

Figure 9: Influence by gripper affixation inclination angle

comes to 0.47, which is the same value of 0.47 resulting from a test

carried out by the traditional method.

Factors That Affect the MeasurementsAffixing the Grippers

Both sides of the suspension ropes are available for affixing the

grippers of the testing device. However, due to the impact from the

static friction between the sheave and the ropes, there lies some

difference in which side of the suspension ropes to affix them. The

measurements are collected and compared time and again for the

difference (Figure 8).

Repeated tests reveal the difference between the measured

weight values by fixing the grippers on either or the other side of

the suspension ropes is approximately 6 kg. In order to make the

test more accurate, we would suggest the test be carried out twice,

relocating the grippers onto the other side of the ropes in a second

test for measurements of the empty car or counterweight, then

taking the average of the two recorded values for the final test result.

Figure 10: Measurements from six repeated tests

Inclination Angle The measurements vary depending on the inclination angle of

the gripper fixation. To figure out which angle would fit in with the right tolerance range in practice for jobsite tests, we tried measuring the weight of empty cars with different angles (Figure 9). We found the measurements tend to increase with increasing inclination angles of the gripper fixation. The right tolerance of the inclination angle for gripper fixation stays within a range of 3º for a maximum fixation error rate of 0.3% of the full scale of the balance coefficient testing device.

ReliabilityTo verify the reliability of the new testing system, a series of

experiments was carried out on different elevators. The same test was repeated six times on each of the elevators selected for assessment of the testing system’s reliability. In the results (Figure 10), we were satisfied to find a desirable deviation rate (0.04%) of the full scale of the elevator balance coefficient testing system.

ConclusionThe new testing system has been tested time and again on

jobsites. Our experimental results show the system can well fulfill the measuring tasks intended without using preset load blocks, which are heavy, redundant and labor intensive. The innovative system can achieve the same measuring accuracy as the traditional method, while saving valuable time and money. The new system has proven reliability in practice by repeated tests. We believe it will find a wide application in the elevator industry in the near future. Acknowledgement
