1. What is the primary purpose of a crane load chart?
A. To determine fuel consumption
B. To identify maximum safe lifting capacities
C. To schedule maintenance
D. To calculate operator wages
Answer: B
Rationale: A load chart provides the crane’s rated lifting capacities based on
configuration, radius, and boom length, ensuring safe operation.
2. Which factor most significantly reduces a crane’s lifting capacity?
A. Engine horsepower
B. Counterweight color
C. Increased load radius
D. Operator experience
Answer: C
Rationale: As load radius increases, leverage forces increase, reducing the
crane’s rated capacity.
3. Before operating a crane, the operator must first:
A. Warm up the engine
, B. Review the load chart and job plan
C. Call the site supervisor
D. Test the horn
Answer: B
Rationale: Reviewing the load chart and lift plan ensures the crane is configured
safely for the intended lift.
4. What does the term “rated capacity” mean?
A. Maximum engine speed
B. Average lifting weight
C. Maximum load the crane can safely lift under specific conditions
D. Weight of the crane
Answer: C
Rationale: Rated capacity is the manufacturer-defined safe lifting limit for a
given configuration.
5. Which crane component provides stability by opposing the load weight?
A. Boom
B. Hoist drum
C. Counterweight
D. Sheave
Answer: C
Rationale: Counterweights counterbalance the load and prevent tipping.
6. What is the function of outriggers on a mobile crane?
A. Increase speed
B. Reduce fuel use
C. Stabilize the crane during lifting operations
D. Improve steering
, Answer: C
Rationale: Outriggers distribute weight and increase the crane’s base of support.
7. When should a crane operator refuse to make a lift?
A. When the load is light
B. When the load weight is unknown
C. When visibility is clear
D. When the signal person is present
Answer: B
Rationale: Unknown load weight can exceed rated capacity, creating a serious
safety hazard.
8. What is a critical lift?
A. Any lift over 10 tons
B. Nighttime lifting only
C. A lift requiring special planning due to high risk
D. Lifting prefabricated materials
Answer: C
Rationale: Critical lifts involve increased risk due to load weight, complexity, or
proximity to hazards.
9. Which hand signal indicates “stop”?
A. Arm waving
B. Thumb up
C. Arm extended with palm down
D. Finger pointing
Answer: C
Rationale: Standard crane hand signals define stop as an arm extended with
palm facing down.
