1. What is the primary purpose of a crane load chart?
A. To estimate fuel consumption
B. To determine lifting capacity under specific conditions
C. To calculate operator wages
D. To schedule maintenance
Rationale: Load charts define safe lifting limits based on boom
length, radius, and configuration.
Correct Answer: B
2. Which factor most affects crane lifting capacity?
A. Operator experience
B. Wind speed
C. Load radius
D. Paint condition
Rationale: The farther the load from the crane, the lower the
lifting capacity.
Correct Answer: C
,3. What does OSHA stand for?
A. Occupational Safety and Health Administration
B. Operational Safety Handling Authority
C. Office of Structural Hazard Assessment
D. Occupational System Hazard Association
Rationale: OSHA is the U.S. agency regulating workplace safety.
Correct Answer: A
4. What is the function of outriggers on a crane?
A. Increase engine power
B. Improve fuel efficiency
C. Stabilize and level the crane
D. Control boom speed
Rationale: Outriggers prevent tipping by increasing crane
stability.
Correct Answer: C
5. Which condition is most dangerous during crane operation?
A. Calm weather
B. Light rain
C. High wind conditions
D. Daylight operation
,Rationale: Wind can destabilize loads and cause tipping or
swing hazards.
Correct Answer: C
6. What is the purpose of a crane inspection before use?
A. Increase lifting speed
B. Ensure safety and detect defects
C. Reduce fuel use
D. Improve appearance
Rationale: Pre-use inspections help prevent mechanical failure.
Correct Answer: B
7. Which signal is universally used for crane operation
communication?
A. Radio signals only
B. Hand signals
C. Written notes
D. Phone calls
Rationale: Standard hand signals ensure clear communication
on site.
Correct Answer: B
8. What is a “load moment”?
, A. Load weight × crane speed
B. Load weight × radius
C. Boom length × fuel rate
D. Load height × wind speed
Rationale: Load moment determines tipping risk.
Correct Answer: B
9. Which PPE is required for crane operators?
A. Sandals
B. Hard hat and safety boots
C. Gloves only
D. Sunglasses only
Rationale: PPE protects against falling objects and site hazards.
Correct Answer: B
10. What is the danger of exceeding crane load capacity?
A. Faster operation
B. Equipment cooling
C. Structural failure or tipping
D. Improved stability
Rationale: Overloading can cause catastrophic failure.
Correct Answer: C
