§How to work safely through the crane material

Crane work is a practical trade, but safety is built on a core of understanding you should be able to do in your sleep. First learn to assess a load — weight, centre of gravity and how it hangs — because that is the starting point for everything else. Then tie the theory together with what you see on site: every time you see a lift, ask yourself whether the rigging, positioning and area are in order.

Important concepts

• 01Rigging – securing the load responsibly to the crane
• 02WLL (working load) — the gear's maximum permissible load
• 03Centre of gravity — where the load's weight balances
• 04Sling angle — the angle between the legs, which affects the force in each sling
• 05Load diagram — crane's lifting capacity at reach and boom angle
• 06Stability and support – support legs, bearing plates, level placement
• 07Daily inspection and statutory main inspection

Good habits

Use the checklist every time, even when the task seems simple — it is precisely there that errors happen. Practise the hand signals so they become automatic, and always agree who is directing. Note inspections and errors in the journal immediately so the documentation is up to date.

Where can you read more

Use the school's course material and the manual for the crane you are working with. The Labour Authority publishes guidance on lifting and cranes, and industry organisations have material on safe rigging. Ask your instructor if a concept is unclear — it is better to ask before the lift than to guess.
