1. A crane is lifting a load and the load begins to swing unexpectedly. The
operator should first:
A. Increase boom angle
B. Stop movement and stabilize the load
C. Increase speed
D. Lower the load rapidly
Answer: B. Stop movement and stabilize the load
Stopping prevents oscillation from increasing and reduces accident risk.
2. A crane is set up on soft ground without outrigger pads. The primary risk is:
A. Increased lifting capacity
B. Crane instability or overturning
C. Faster operation
D. Reduced fuel use
Answer: B. Crane instability or overturning
Soft ground cannot distribute load safely.
3. A load chart must always be referenced based on:
A. Operator preference
B. Exact crane configuration and conditions
,C. Weather only
D. Load color
Answer: B. Exact crane configuration and conditions
Capacity depends on setup, radius, and configuration.
4. A crane exceeds its rated load moment. The most likely result is:
A. Improved stability
B. Structural failure or tipping
C. Higher efficiency
D. Reduced swing
Answer: B. Structural failure or tipping
Overloading compromises stability.
5. Wind speed increases significantly during a lift. The operator should:
A. Continue lift normally
B. Stop lift and secure load
C. Increase boom length
D. Reduce counterweight
Answer: B. Stop lift and secure load
Wind creates dynamic load instability.
6. A crane’s load is farther from the center pin. This increases:
A. Stability
B. Load moment
C. Efficiency
D. Fuel consumption only
Answer: B. Load moment
Greater radius increases tipping force.
, 7. A signal person gives conflicting hand signals. The operator should:
A. Follow closest signal
B. Stop operation until clarified
C. Continue lifting
D. Increase speed
Answer: B. Stop operation until clarified
Safety requires clear communication.
8. A crane begins to lean during setup. Immediate action is:
A. Continue operation
B. Stop and reassess ground conditions
C. Increase counterweight
D. Extend boom
Answer: B. Stop and reassess ground conditions
Lean indicates instability.
9. The purpose of outriggers is to:
A. Increase fuel efficiency
B. Improve crane stability
C. Increase load weight
D. Reduce boom length
Answer: B. Improve crane stability
Outriggers distribute load.
10. A crane is operating near power lines. Minimum safe distance must be:
A. Ignored if careful
B. Maintained per safety regulations
C. Reduced for efficiency
D. Based on load weight only
