Show hintHide hint
Think about the center of balance.
Question 2.
What should be done to ensure a crane's maximum lifting capacity?
Show hintHide hint
Consider how cranes convey weight.
3Question 3.
What does 'X' represent in crane stability calculations?
- Distance from the load line to the fulcrum
- Distance from the boom to the ground
- The total length of the crane
Show hintHide hint
Think about how loads relate to pivot points.

- True
- False
Show hintHide hint
Consider their role in stability.
Question 5.
A crane is set on a slope and not using its outriggers. What safety precautions should be taken before proceeding with a load?
Show hintHide hint
Review how slope affects balance.
Question 6.
Calculate the potential lifting capacity of a crane if the operating radius changes from 10m to 15m. What happens if outriggers are not used?
Show hintHide hint
Think about the shift in center of gravity and its effects.
