1. What is the primary purpose of a tower crane load chart?
A. To estimate fuel consumption
B. To determine maximum safe lifting capacities
C. To schedule maintenance intervals
D. To measure wind speed
Rationale: Load charts define safe working limits based on
radius and configuration.
Correct Answer: B
2. Which factor MOST affects a tower crane’s lifting capacity?
A. Operator weight
B. Wind direction
C. Load radius
D. Paint condition
Rationale: The farther the load from the mast, the lower the
capacity.
Correct Answer: C
,3. What is the function of the crane’s slewing system?
A. Lifting loads vertically
B. Moving the crane along rails
C. Rotating the crane horizontally
D. Balancing counterweights
Rationale: Slewing allows rotation of the jib.
Correct Answer: C
4. What is a critical safety check before starting operations?
A. Checking operator clothing
B. Inspecting control labels only
C. Conducting a pre-operational inspection
D. Painting the cab
Rationale: Daily inspections ensure safe equipment condition.
Correct Answer: C
5. What does a tower crane’s moment limiter do?
A. Measures fuel use
B. Prevents overload conditions
C. Controls cabin temperature
D. Adjusts lighting
Rationale: It stops operations if safe load limits are exceeded.
Correct Answer: B
,6. What is the primary hazard of exceeding crane load limits?
A. Engine overheating
B. Structural failure or collapse
C. Slow hoisting
D. Increased fuel consumption
Rationale: Overloading can cause catastrophic failure.
Correct Answer: B
7. What should be inspected on wire ropes regularly?
A. Color
B. Length markings
C. Broken wires and wear
D. Temperature
Rationale: Rope integrity is critical for safe lifting.
Correct Answer: C
8. What is the purpose of counterweights on a tower crane?
A. Increase lifting speed
B. Balance the load and prevent tipping
C. Reduce electricity use
D. Control wind pressure
, Rationale: Counterweights stabilize the crane during lifts.
Correct Answer: B
9. Which condition is MOST dangerous during crane
operation?
A. Light rain
B. High wind speeds
C. Clear skies
D. Warm temperature
Rationale: High winds can destabilize loads and the crane.
Correct Answer: B
10. What is the correct action if a load swings unexpectedly?
A. Increase hoisting speed
B. Stop operation and stabilize load
C. Continue movement
D. Add more load
Rationale: Uncontrolled swing indicates instability.
Correct Answer: B
11. What is the function of the trolley on a tower crane?
A. Rotates the crane
B. Moves the load along the jib
