5. How does excessive lateral leaning affect the stability of a compact crane during lifting operations?

 

A) It can lead to the crane becoming unstable and potentially overturning

B) It has no effect on the crane’s stability

C) It enhances stability due to load distribution

D) It ensures smoother load maneuvering

 

Correct answer: A) It can lead to the crane becoming unstable and potentially overturning

 

6. What can happen to the hoist rope during high winds affecting loads with a large surface area?

 

A) It stays aligned vertically due to wind resistance

B) It may not cause the crane to go out of radius

C) It remains unaffected by the wind

D) It swings due to gusts and misaligns vertically

 

Correct answer: D) It swings due to gusts and misaligns vertically

 

7. In what situation is the weight applied to an outrigger leg at its maximum?

 

A) When the crane is lifted off the ground

B) At any time the crane is in operation

C) When the load is at its highest point

D) When the boom or jib is fully extended and lifting a heavy load

 

Correct answer: D) When the boom or jib is fully extended and lifting a heavy load

 

8. Why should the boom of the crane be kept well clear of overhead power lines?

 

A) To enhance visibility at the worksite

B) To minimize wear on the boom structure

C) To avoid disturbing electrical signals

D) To reduce the risk of arcing and potential accidents

 

Correct answer: D) To reduce the risk of arcing and potential accidents

 

9. What is the primary role of assessing the ability of the floor to support the crane’s weight?

 

A) To enhance the crane’s lifting capacity

B) To avoid exceeding the crane’s maximum radius

C) To prevent the crane from overturning

D) To ensure stable pick and carry operations

 

Correct answer: C) To prevent the crane from overturning

 

10. How does the extension of outriggers or stabilisers typically impact stability in compact cranes?

 

A) Maximum stability achieved

B) Reduced stability

C) Improved flexibility

D) No impact on stability

 

Correct answer: A) Maximum stability achieved

 

11. When can operators of compact cranes undertake adjustments to the machine?

 

A) When trained and competent for the specific model

B) Only during extreme operating conditions

C) Only during weekly checks

D) When additional training is provided

 

Correct answer: A) When trained and competent for the specific model

 

12. What is the lift plan for and who devises it?

 

A) To identify the operator’s duties; devised by the operator

B) To identify risks and sequence of work; devised by the lift supervisor

C) To identify potential accidents; devised by the site manager

D) To ensure safe maneuvering; devised by the crane manufacturer

 

Correct answer: B) To identify risks and sequence of work; devised by the lift supervisor

 

13. What is the function of the RCI and what information does it provide to the operator?

 

A) Warns about crane elevation; load position

B) Provides maintenance alerts; ground conditions

C) Warns about approaching maximum capacity; configuration limits

D) Indicates weather conditions; load weight

 

Correct answer: C) Warns about approaching maximum capacity; configuration limits

 

14. What action should be taken by the operator when work concludes or during breaks regarding the compact crane’s boom or jib?

 

A) Leave the crane at its current elevation

B) Lower the boom or jib to ensure no collision risk

C) Leave the crane extended for quick restart

D) Wait for the lift planner’s instructions

 

Correct answer: B) Lower the boom or jib to ensure no collision risk

 

15. What is the primary function of the rated capacity indicator (RCI) in a crane?

 

A) Providing warnings when approaching or exceeding maximum capacity

B) Alerting when maintenance is required

C) Indicating the crane’s current location

D) Displaying real-time weather conditions

 

Correct answer: A) Providing warnings when approaching or exceeding maximum capacity
