Introduction to Rigging – Basic


INTRODUCTION TO RIGGING – BASIC

What is rigging?Rigging work means the use of mechanical load shifting equipment (and associated gear) to:

• Move, place or secure a load using plant, equipment or members of a building or structures to ensure the stability of those members

• The setting up or dismantling of cranes or hoists.

Boom-type elevating work platformRiggers often perform their work from Elevated work platforms (EWPs). You must hold the correct High Risk Work License to operate an EWP with a boom length of 11 metres or more.


PLAN TASK

Plan task

Element 1


PLAN TASK

Have you chosen the right plant to use? For example, crane.

Is the equipment available and suitable for the job?

How much does the load weigh?

Any plans for doing the job.

Tripping hazards

Identify workplace hazardsA hazard is anything that can hurt you or others while you work. The government classes rigging as high risk. By law, only a licensed person can do rigging work. The licence includes knowing what workplace hazards to look for — and the causes.

While there is no substitute for experience, this book shows you the hazards you need to know about while you do rigging work.

PC 1.4


PLAN TASK

Lifting a beam that won’t moveYou must always take care if a crane is lifting a beam near you. But if the crane’s boom is being lifted and the beam doesn’t move, stand clear.

The beam might suddenly move.

• This could damage the crane

• It might also injure you.

Working in high windsWorking in high winds on steel structures is very dangerous.

• There is a risk you could be knocked over

• There is also a risk you might be blown off the structure.

PC 1.4


PLAN TASK

Risk control and safety measures What are risk/hazard controls? They are actions you take to control, reduce the chance, or prevent a danger that can injure or hurt you.

• You use the actions to do away with or to reduce risk to workmates and property

• Take these actions before you start the task.

What is a hazard?A hazard is anything that can harm you or others while you work.

What is a risk?A risk is the chance of a hazard injuring or hurting a person.In other words, what is the chance of the hazard hurting you?

What is control?A control is what you can do to stop the hazard from hurting or killing someone.

Hazard, risk and control

PC 1.4


PLAN TASK

6. Use personal protective equipment (PPE) (wear safety clothing)

Wear safety clothing and PPE to control hazards. Avoid relying on these as the only way to control hazards. Make sure the PPE is right for you and the company has trained you in how to use it. For example, wear high-visibility clothing so workmates can see you more easily.

Hard hat

Safety gloves

Safety vest

Boots that cover the whole foot

Ear muffs

Long sleeved top

Sunscreen

Safety glasses/goggles, Sunglasses

Dust mask

Long pants

As a minimum, a rigger should wear a safety helmet, rubber-soled boots, a hi-vis vest/clothing and gloves.

PLAN TASK

Types of forces and loads

Static loadsLoads with no or little movement (consistently applied load).

Live loadsAlso called the lifted load. The load that is being lifted.

Dead loadsThe weight of a crane, hoist or scaffold without a load.

Dead load

Live load

Static load

The types of forces and loads you have to think about when planning the rigging work are:

• Dynamic forces

• Wind load

• Live loads

• Dead loads

• Static loads

PC 1.7


PLAN TASK

Calculate the weight of a loadThe crane operator is responsible for checking the weight of the load lifted. The weight of the load determines the lifting equipment you need to lift it.

Always check the weight of the load when you plan the job, before lifting the load.

To find the weight of a load:

Weigh the loadCalculate the weight of a load. It may be necessary to calculate the weight of the load yourself.

Calculations need to include the pallet and lifting gear.For example – 10 × 20 kg + 15 kg = 215 kg

Look at the load itself or the packing it comes in. The weight may be marked on the load or you can weigh it yourself.

Read the weighbridge certificate, consignment note or other paperwork.

15 kg

PC 1.7


PLAN TASK

Calculation examples

Example 1 – Pallet of cement bags

10 × 20 kg bags of cement

= 200 kg + 30 kg (pallet)

= 230 kg

Example 2 – Drum filled with water

1 m

1 m

0.79 or 79% of square

Formula to calculate volume of water:Diameter squared × 0.79 × the height of the drumD2 × 0.79 × 1.70.9 × 0.9 × 0.79 × 1.7 = 1.08783 m3

Volume = 1.0878 m3

Final drum weight with water

Volume × unit weight of water + drum tare weight

1.0878 × 1000 + 260

= 1347.83 kg

Job: Move a drum filled with water.

Specifications:Drum diameter – 0.9 metre (900 mm)Drum height – 1.7 metres (1700 mm)Drum tare weight – 260 kgWater – 1 tonne per cubic metre

Job: Lift a pallet with 10 bags of cement on it.

Specification:Bag weight – 20 kgPallet weight – 30 kg

Calculate the weight of a load (continued)

30 kg
