QUESTIONS 1–150
Question 1
A mobile crane operator arrives at a NYC construction site and discovers that the crane's
configuration differs from the configuration documented for the planned lift. What should
the operator do FIRST?
A. Proceed if the actual load is below the crane's rated capacity
B. Verify the actual configuration against the applicable load chart and lift plan before
hoisting
C. Reduce operating radius until the lift becomes conservative
D. Ask the signalperson whether the change appears acceptable
, Correct Answer: B
- Explanation: Crane capacity depends on configuration as well as load and radius. The
actual configuration must be verified against the applicable chart and planned operation
before lifting.
Question 2
A crane's load chart lists several boom lengths and operating radii. The operator determines
that the planned radius falls between two listed radii. Which approach is most appropriate?
A. Use the larger radius because it provides greater capacity
B. Average the capacities of the two radii
C. Use the applicable manufacturer-prescribed method, generally treating the condition
conservatively
D. Use the shorter radius because it represents the initial position
Correct Answer: C
- Explanation: Load-chart interpolation must follow the manufacturer's instructions. When
interpolation is not expressly permitted, the operator must use the more restrictive
applicable value.
Question 3
During a lift, the operator notices that one outrigger pad has begun to settle. The load is
suspended and stable. What is the best immediate response?
A. Continue the lift slowly to avoid dynamic loading
B. Boom down to transfer weight to the load
C. Stop the operation and address the foundation/support condition before continuing
D. Increase engine speed to maintain hydraulic pressure
Correct Answer: C
- Explanation: Outrigger settlement can reduce stability and alter crane geometry.
Continuing a suspended lift can magnify the hazard.
Question 4
Which factor most directly explains why increasing load radius can substantially reduce a
mobile crane's allowable capacity?
A. Engine horsepower decreases with radius
B. The load moment increases as horizontal distance from the tipping axis increases
C. Hydraulic oil pressure automatically decreases
D. Boom weight becomes negligible
, Correct Answer: B
- Explanation: Load moment is fundamentally related to load multiplied by horizontal
radius. Increasing radius therefore increases overturning moment.
Question 5
An operator is given a load weight but no reliable information about the rigging weight.
What is the safest professional decision?
A. Ignore rigging weight because it is normally insignificant
B. Estimate it after the load is airborne
C. Determine the rigging weight before calculating the total suspended load
D. Assume the load chart already includes rigging
Correct Answer: C
- Explanation: The crane must account for the complete suspended load, including
applicable below-the-hook equipment and rigging.
Question 6
A mobile crane is positioned on a slope. Which consideration is most critical before lifting?
A. Whether the cab is facing uphill
B. Whether the crane can physically travel on the slope
C. Whether the crane can be safely leveled and supported in accordance with manufacturer
requirements
D. Whether the load can be reached without extending the boom
Correct Answer: C
- Explanation: Crane stability depends heavily on proper leveling and support.
Manufacturer limitations and site conditions govern acceptable setup.
Question 7
The operator's load moment indicator indicates a rapidly increasing percentage of rated
capacity during a pick. What does this most likely indicate?
A. The load is becoming lighter
B. The effective operating condition is becoming more demanding
C. The boom is automatically gaining capacity
D. The outriggers are increasing their reaction capacity
, Correct Answer: B
- Explanation: Increasing load moment utilization indicates that the combination of load,
radius, and configuration is approaching the crane's allowable capacity.
Question 8
A crane operator believes a load weighs 18 tons, but the rigging supervisor estimates 20
tons. What should control the capacity calculation if no verified weight is available?
A. The lower estimate
B. The operator's estimate
C. The higher conservative estimate until the actual weight is verified
D. The average of both estimates
Correct Answer: C
- Explanation: Capacity decisions should not be based on optimistic assumptions. The
actual or conservatively established weight must be used.
Question 9
A crane is configured with a jib that is not shown in the load-chart configuration selected by
the operator. What is the correct action?
A. Use the main-boom chart because the jib does not carry the entire load
B. Apply a percentage reduction
C. Locate the correct configuration and corresponding manufacturer information before
lifting
D. Lift only at minimum radius
Correct Answer: C
- Explanation: Attachments can materially alter capacity and structural loading. The
correct configuration must be specifically accounted for.
Question 10
Which condition presents the greatest immediate concern when establishing a crane's
working area?
A. The ground is visually unattractive
B. Underground utilities or voids may compromise bearing capacity
C. The operator prefers a different orientation
D. The load is painted a dark color
