1. What does the RCI notify the operator of while lifting a load?

2. Why is it crucial for operators to know the factors that can cause instability in telehandlers?

3. When must Remote Control Indicators (RCIs) not be bypassed or overridden?

4. On what types of telehandlers are front-mounted stabilisers usually fitted?

5. What is the proper safety requirement for temporary or fixed access ladders?

6. Why do lifting safety guidelines advise keeping the movement of a suspended load overhead to a minimum?

7. When a trench has a sloped side, from where should the horizontal distance be measured?

8. Why is it important for temporary or built-in access ladders to provide good foot grip?

9. Where must a crawler crane’s hook be placed when preparing to lift a load?

10. What could happen if one or both tracks of a crawler crane start to sink into the ground?

11. When is it necessary to inspect the ground conditions for a crawler crane?

12. In trenching operations, what does the expression D + d – 2h stand for?

13. Which load centre is standard for most telehandlers?

14. Why must the jib of a tower crane be lowered when the shift ends?

15. In the equation D + d ? 2h, which variable equals zero when the trench walls are vertical?

16. What needs to be in place when people are being lifted?

17. What action should be taken if the centre of gravity of a heavy load shifts beyond the machine’s load centre?

18. What does the law require to be carried out for all lifting operations?

19. What might occur if you swing or turn too quickly while carrying a heavy load, especially close to the crane?s maximum capacity?

20. What might occur if the boom comes too near an overhead power line?
