GENERAL CRANE SAFETY PRACTICE EXAM (1–100)
(Mixed difficulty: OSHA, ASME, rigging, signaling, operations)
QUESTIONS 1–20
1. The most important reason for conducting a pre-operation inspection is to:
A. Save time during lifts
B. Reduce operator fatigue
C. Identify hazards before operation
D. Record crane hours
Rationale: Pre-operation inspections detect defects and hazards before lifting begins.
2. A crane boom moving unexpectedly is usually caused by:
A. Proper lubrication
B. Overheating hydraulic oil
C. Hydraulic system failure
D. A worn load chart
Rationale: Unintended boom movement indicates hydraulic malfunction.
3. According to OSHA, who is authorized to signal a crane?
A. Any employee nearby
B. Only the lift director
C. Only a designated and qualified signal person
D. The crane manufacturer
Rationale: OSHA requires a designated signal person trained and evaluated.

,4. Before lifting a load, the operator should FIRST:
A. Raise the load rapidly
B. Check that the hook is centered over the load
C. Extend the boom fully
D. Swing the crane before tensioning
Rationale: Side loading is dangerous; hook must be centered.
5. A shock load occurs when:
A. A load is lifted slowly
B. A load is swung gently
C. A load is jerked suddenly
D. A load is lowered smoothly
Rationale: Sudden movement increases load force drastically.
6. The crane’s load chart is based on:
A. Maximum counterweight capacity
B. Ideal surface conditions
C. Structural and stability limits
D. Tire size
Rationale: Charts combine structural strength + tipping limits.
7. When working near power lines, OSHA requires a minimum clearance of:
A. 5 ft
B. 10 ft
C. 15 ft
D. 25 ft
Rationale: Minimum is 10 ft for lines ≤50 kV.
8. If the crane operator loses sight of the signal person, the operator must:
A. Continue lifting slowly
B. Stop operations immediately
C. Swing the crane to locate them
D. Lower the boom fully
Rationale: All crane movement must stop when communication is lost.
EXAMPREPMASTER
,9. The safest place to stand during a lift is:
A. Under the load
B. Between load and a fixed object
C. Outside the fall zone
D. Near the crane counterweight
Rationale: Fall zone includes the horizontal reach of the boom.
10. A load moment indicator (LMI) measures:
A. Load weight only
B. Boom deflection
C. Tipping potential / moment load
D. Hook lubrication
Rationale: LMI calculates load moment vs. crane capacity.
11. The BEST way to prevent side loading is to:
A. Increase radius
B. Boom down slightly
C. Keep the hook directly above the load
D. Add counterweights
Rationale: Side loading can cause boom failure.
12. When operating a crane on soft ground, the operator should:
A. Ignore surface conditions
B. Always increase speed
C. Use pads, mats, or cribbing under outriggers
D. Retract outriggers fully
Rationale: Mats distribute weight and increase stability.
13. What must be done before lifting personnel with a crane?
A. Use a standard cargo basket
B. Obtain a written lift plan
C. Operate at max radius
D. Secure personnel with cargo hooks
Rationale: Personnel lifts require strict planning and approved man baskets.
EXAMPREPMASTER
, 14. A load is most stable when:
A. It is long and narrow
B. Center of gravity is low and centered
C. Rigging angles are shallow
D. Sling legs differ in length
Rationale: Stability depends on centered center of gravity.
15. A tagline is used to:
A. Increase lifting height
B. Reduce counterweight needs
C. Control load rotation during lifting
D. Measure load radius
Rationale: Taglines help control swing and rotation.
16. The safest sling angle is:
A. 10°
B. 30°
C. 45°
D. 60° or greater
Rationale: Larger angles reduce tension on sling legs.
17. A “hoist” signal from the signal person means:
A. Raise the boom
B. Lower the boom
C. Raise the load
D. Stop
Rationale: “Hoist” = lift the hook/load.
18. When traveling with a load, the operator should:
A. Lift load as high as possible
B. Keep load close to ground
C. Travel at maximum speed
D. Swing load frequently
Rationale: Low load height improves stability.
