Defination of elevator.

1. A lift or an elevator is a transport device used to move goods or people vertically.2. An elevator (or lift) is a vertical transport vehicle that efficiently moves people or

goods between floors of a building. They are generally powered by electric motors

which is drive traction cables.

History of elevator.

Elevator design by the German engineer Konrad Kyeser (1405).The first reference to an

elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes built

his first elevator probably in 236 B.C. In some literary sources of later historical periods,

elevators were mentioned as cabs on a hemp rope and powered by hand or by animals. It is

supposed that elevators of this type were installed in the Sinai monastery of Egypt.

In 1000, the Book of Secrets by Ibn Khalaf al-Muradi in Islamic Spain described the use of an

elevator-like lifting device, in order to raise a large battering ram to destroy a fortress. In the

17th century the prototypes of elevators were located in the palace buildings of England and

France.

In 1793 Ivan Kulibin created an elevator with the screw lifting mechanism for the Winter

Palace of Saint Petersburg. In 1816 an elevator was established in the main building of sub

Moscow village called Arkhangelskoye. In 1823, an "ascending room" made its debut in

London.

In the middle 1800's, there were many types of crude elevators that carried freight. Most of

them ran hydraulically. The first hydraulic elevators used a plunger below the car to raise or

lower the elevator. A pump applied water pressure to a plunger, or steel column, inside a

vertical cylinder. Increasing the pressure allowed the elevator to descend. The elevator also

used a system of counter-balancing so that the plunger did not have to lift the entire weight of

the elevator and its load. The plunger, however, was not practical for tall buildings, because it

required a pit as deep below the building as the building was tall. Later a rope-geared elevator

with multiple pulleys was developed.

Henry Waterman of New York is credited with inventing the "standing rope control" for an

elevator in 1850.

In 1852, Elisha Otis introduced the safety elevator, which prevented the fall of the cab if the

cable broke. The design of the Otis safety elevator is somewhat similar to one type still used

today. A governor device engages knurled roller locking the elevator to its guides should the

elevator descend at excessive speed. He demonstrated it at the New York exposition in the

Crystal Palace in 1854.

On March 23, 1857 the first Otis passenger elevator was installed at 488 Broadway in New

York City. The first elevator shaft preceded the first elevator by four years. Construction for

Peter Cooper's Cooper Union building in New York began in 1853. An elevator shaft was

included in the design for Cooper Union, because Cooper was confident that a safe passenger

elevator would soon be invented. The shaft was cylindrical because Cooper felt it was the

most efficient design. Later Otis designed a special elevator for the school. Today the Otis

Elevator Company, now a subsidiary of United Technologies Corporation, is the world's

largest manufacturer of vertical transport systems.

The first electric elevator was built by Werner von Siemens in 1880. The safety and speed of

electric elevators were significantly enhanced by Frank Sprague.

The development of elevators was led by the need for movement of raw materials including

coal and lumber from hillsides. The technology developed by these industries and the

introduction of steel beam construction worked together to provide the passenger and freight

elevators in use today.

Traction elevator in Wisma Sumber Asli.

1. In a "traction" lift, cars are pulled up by means of rolling steel ropes over a deeplygrooved pulley, commonly called a sheave in the industry. The weight of the car is

balanced with a counterweight. In this office building, sometimes two lifts always

move synchronously in opposite directions, and they are each other's counterweight.

Traction elevators are better suited for taller buildings, since they are capable of much

greater speeds and heights. Support for rail fastening at intervals where specified by

elevator contractor, including separator beams between hoistways.

2. A suitable machine room with legal access & clearances properly heated & ventilated.In Wisma Sumber Asli, temperature to be maintained in the lift room is between 10 C

and 50 F to 20 C and 80 F.

Staircase in Wisma Sumber Asli Building.

Definition of staircase.

1. Simply stairs are names for a construction designed to bridge a large vertical distanceby dividing it into smaller vertical distances, called steps. Stairways may be straight,

round, or may consist of two or more straight pieces connected at angles.

2. Staircase is an important part in building construction3. It is a simple path fluctuations from one level to another level, especially during

emergencies.

Types of stair used in Wisma Sumber Asli Building.

- half turn stair.- Appliances include double row of stairs that up from floor to floor on a platform of

turning through 180 (half turn) in the mid-tier. the steps are parallel. The order of

steps on the floor above the normal end of the floor above the starting point on the

lower floor. This will produce the same number of stairs to the two string ladder. Use

half-round ladder is suitable as a ladder to the office as the building of this Wisma

Sumber Asli.

Step detail.

The step is composed of the tread and riser.

y tread - The part of the step that is stepped on. It is constructed to the samespecifications (thickness) as any other flooring. The tread "length" is measured from

the outer edge of the step to the vertical "riser" between steps.

yriser - The vertical portion of the step between steps. This may be missing for an"open" stair effect.

y nosing - An edge part of the tread that protrudes from the riser beneath. If it is present,this means that horizontally, the total "run" length of the stairs is not simply the sum of

the tread lengths, the treads actually overlap each other slightly.

stairs allows stairs to fit where they would not otherwise, or provides privacy to the upper

level as visitors downstairs cannot simply look up the stairs to the upper level due to the

change in direction
