1. What is the primary purpose of a crane load chart?
A. To estimate fuel consumption
B. To determine safe lifting capacity under various conditions
C. To list maintenance schedules
D. To identify crane manufacturers
Answer: B
Rationale: The load chart provides critical information on safe lifting
capacities based on boom length, radius, and configuration.
2. Before operating a tower crane, the operator should first:
A. Start lifting immediately
B. Check weather conditions and crane inspection status
C. Increase counterweight
, D. Disable warning systems
Answer: B
Rationale: Pre-operation checks ensure safe environmental and
equipment conditions before any load is handled.
3. What is the most dangerous effect of exceeding crane load limits?
A. Faster operation
B. Structural collapse or tipping
C. Reduced fuel efficiency
D. Increased hook speed
Answer: B
Rationale: Overloading can cause crane instability, leading to
collapse or tipping accidents.
4. Who is responsible for determining the weight of a load before lifting?
A. Ground worker only
B. Crane operator only
C. Supervisor only
D. All involved personnel collaboratively
Answer: D
Rationale: Safe lifting requires shared responsibility to ensure
accurate load weight verification.
5. What is the purpose of a tag line during a lift?
A. Increase load weight
B. Control load swing and rotation
, C. Signal the crane operator
D. Measure wind speed
Answer: B
Rationale: Tag lines help stabilize and control the movement of a
suspended load.
6. Which condition most affects crane stability?
A. Operator clothing
B. Wind speed
C. Paint color
D. Radio frequency
Answer: B
Rationale: High wind speeds can significantly reduce crane stability
and safe lifting capacity.
7. The term “radius” in crane operations refers to:
A. Crane height
B. Distance from crane center to load
C. Load weight
D. Hook block size
Answer: B
Rationale: Radius is the horizontal distance from the crane’s center
of rotation to the load.
8. What must be verified before lifting any load?
A. Operator’s salary
, B. Load weight and rigging integrity
C. Weather forecast for next week
D. Paint condition of crane
Answer: B
Rationale: Ensuring correct load weight and secure rigging prevents
lifting accidents.
9. Which device prevents over-hoisting of the hook block?
A. Boom deflector
B. Hoist limit switch
C. Load indicator
D. Counterweight sensor
Answer: B
Rationale: The hoist limit switch prevents the hook from being pulled
too high into the boom.
10. What is the safest action when wind speeds exceed
manufacturer limits?
A. Continue operations carefully
B. Increase counterweight
C. Stop crane operations
D. Reduce load weight only
Answer: C
Rationale: Crane operations must stop when wind exceeds safe
operational limits.
