1. When inspecting a mobile crane, which of the following is the primary
concern regarding the outriggers?
A. Ensuring they are fully retracted during operation
B. Checking that they are positioned on a hard, level surface and fully
extended
C. Verifying they are painted according to manufacturer specifications
D. Ensuring the outriggers are elevated above ground for clearance
B. Checking that they are positioned on a hard, level surface and fully
extended
Rationale: Outriggers provide stability and prevent tipping; they must be
fully extended and placed on solid, level ground to ensure safe crane
operation.
2. During a crane pre-operation inspection, the operator notices cracks in
the boom. What is the correct course of action?
A. Continue operation at reduced load
B. Report the cracks and remove the crane from service until repaired
C. Apply temporary reinforcement and proceed
D. Only operate during daylight hours
B. Report the cracks and remove the crane from service until repaired
Rationale: Structural integrity is critical; any cracks in the boom
,compromise safety, and the crane must not be used until professionally
repaired.
3. What is the purpose of the load chart on a crane?
A. To display crane color coding
B. To indicate maximum lifting capacities at various boom lengths and
angles
C. To document inspection dates
D. To log operator work hours
B. To indicate maximum lifting capacities at various boom lengths and
angles
Rationale: The load chart provides essential information for safe lifting
operations, preventing overloading and potential accidents.
4. Which of the following is a key responsibility of a crane safety
inspector?
A. Painting the crane
B. Verifying the crane’s compliance with OSHA and ANSI standards
C. Operating the crane during heavy lifts
D. Supervising daily worksite deliveries
B. Verifying the crane’s compliance with OSHA and ANSI standards
Rationale: Safety inspectors ensure cranes meet federal and industry
safety standards, identifying hazards before operation.
5. Which environmental factor most critically affects crane operation
safety?
A. Ambient temperature
B. Wind speed and direction
C. Noise levels on site
D. Ground color
B. Wind speed and direction
Rationale: High winds can destabilize cranes and affect load control,
making wind monitoring crucial for safe operations.
, 6. When performing an annual crane inspection, which component
requires checking for excessive wear and lubrication?
A. Paint coating
B. Wire ropes and sheaves
C. Operator cabin windows
D. Engine air filter
B. Wire ropes and sheaves
Rationale: Wire ropes and sheaves experience high stress and friction;
inspection and lubrication prevent failures and maintain safe lifting
operations.
7. A crane’s rated capacity is 20 tons. The operator plans to lift a 22-ton
load. What action should the inspector recommend?
A. Proceed with caution
B. Use a smaller load incrementally
C. Never exceed the rated capacity; cancel or reschedule the lift
D. Lift slowly to reduce stress
C. Never exceed the rated capacity; cancel or reschedule the lift
Rationale: Exceeding rated capacity risks structural failure and is a critical
safety violation.
8. Which signal should a crane operator follow if the signal person
indicates “Stop” using hand signals?
A. Continue lifting slowly
B. Immediately stop all crane movement
C. Lower the load partially
D. Swing the boom in the opposite direction
B. Immediately stop all crane movement
Rationale: Clear communication via standardized signals prevents
accidents, and the “Stop” signal requires immediate cessation of all
movement.
, 9. In a crane inspection report, what is the significance of noting “load-
limiting devices operational”?
A. Confirms the crane cannot exceed rated load
B. Records operator credentials
C. Verifies paint and cosmetic condition
D. Indicates engine efficiency
A. Confirms the crane cannot exceed rated load
Rationale: Load-limiting devices prevent overloading, and verifying their
operation ensures the crane will not lift beyond safe limits.
10. During site inspection, the ground beneath a crane appears soft
and uneven. What is the safest procedure?
A. Place wooden mats or cribbing to stabilize the crane
B. Ignore and proceed with caution
C. Reduce load by half
D. Operate only during dry conditions
A. Place wooden mats or cribbing to stabilize the crane
Rationale: Soft or uneven ground can compromise stability; proper mats or
cribbing distribute weight and prevent tipping.
11. When inspecting hydraulic systems on a crane, which condition
is most concerning?
A. Clean hydraulic fluid
B. Minor paint chips on the cylinder
C. Leaks or low fluid levels
D. Lubricated pivot points
C. Leaks or low fluid levels
Rationale: Hydraulic leaks or insufficient fluid can cause system failure, loss
of control, or unexpected movement, posing significant safety hazards.
12. Which of the following is required for proper crane rigging
inspection?
A. Checking for rust or fraying on slings and chains
