Question 1.
What does 'u' measure in crane operations?
Show hintHide hint
Think about the crane's physical layout.
Question 2.
What is W in the context of crane lifting?
Show hintHide hint
Consider what the crane is lifting.
3Question 3.
What is the purpose of equating moments in crane operation?
- To determine weight
- To ensure stability
- To measure speed
Show hintHide hint
Think about safety and balance.
4Question 4.
True or False: The maximum lifting capacity of a truck-mounted crane can exceed 100% of its tipping load.
- True
- False
Show hintHide hint
Consider the implications of lifting beyond limits.
Question 5.
A crane is lifting a load with a weight of 800 kg. If the operational radius is 12 meters, calculate the maximum allowed lift based on a 75% safety margin.
Show hintHide hint
Apply the safety margin to the load weight.
Question 6.
Analyze a scenario where a truck-mounted crane has a tipping load of 2000 kg. If the operational radius is increased from 5m to 15m, discuss the implications for stability and lifting capacity.
Show hintHide hint
Focus on how the load position influences stability.
