§Study material — crane operator
This page brings together the trade's core concepts so you have a quick reference when you study or need to explain a safe lift. Use it together with the articles and templates.
You should be able to explain this
- 01Why a crane's lifting capacity falls with reach — the load curve
- 02What makes a crane stable, and why stability is crucial
- 03Why the trade requires a certificate and competence
- 04How a safe lift is planned and carried out step by step
- 05Why only one person gives signals at a time
Central concepts
| Concept | Short explanation |
|---|---|
| Load curve | How much the crane can lift at different ranges |
| Support legs | Legs that support and stabilize the mobile crane |
| Rigging | Securing the load so it hangs level and safely |
| PLACEHOLDER_82 | Straps, chains, shackles with marked bearing capacity |
| Load limiter | Electronics that warns and stops at overload. |
| Rigger | The one who secures the load and gives signals |
| Centre of gravity | The point a load balances on |
Safety at a glance
- 01Position the crane stably on bearing substrate with support legs extended
- 02Always stay inside the load basket
- 03Keep safe distance to electrical wires
- 04No one under suspended load
- 05Stop the lift in case of doubt, strong wind or unclear signal
Check yourself
- 01Can you explain why lifting capacity decreases when the arm reaches further out?
- 02Can you name two main causes of serious crane accidents?
- 03Can you describe a safe lift step by step?
