1. What is the primary purpose of a crane load chart?
A. To estimate fuel consumption
B. To determine lifting capacity under specific conditions
C. To schedule maintenance intervals
D. To calculate engine horsepower
Answer: B
Rationale: Load charts provide the maximum allowable lifting
capacity of a crane based on boom length, angle, configuration, and
operating conditions. They are essential for safe lifting operations and
preventing overload.
2. What organization sets most crane safety standards in the United
States?
A. EPA
,B. OSHA
C. DOT
D. FEMA
Answer: B
Rationale: OSHA (Occupational Safety and Health Administration)
establishes and enforces workplace safety standards, including crane
operation regulations under 29 CFR 1926 Subpart CC.
3. What is the most important factor affecting crane stability?
A. Operator experience
B. Counterweight color
C. Center of gravity
D. Tire pressure only
Answer: C
Rationale: A crane’s stability depends heavily on maintaining its
center of gravity within the base of support. Shifting loads or improper
setup can cause tipping.
4. What should be done before operating a crane each day?
A. Paint inspection marks
B. Perform a pre-operation inspection
,C. Increase engine RPM
D. Replace hydraulic oil
Answer: B
Rationale: A daily pre-operation inspection ensures that all crane
components are functioning properly and safely before use.
5. Which signal is typically used to stop all crane operations
immediately?
A. Arm extended, palm down moving horizontally
B. Both arms crossed
C. One hand pointing upward
D. Clapping hands
Answer: A
Rationale: The stop signal is universally recognized as a palm-down
horizontal motion, indicating immediate cessation of operations.
6. What does “SWL” stand for in rigging?
A. Safe Weight Load
B. Static Work Limit
C. Safe Working Load
D. Structural Weight Limit
, Answer: C
Rationale: Safe Working Load refers to the maximum load a piece of
rigging equipment can safely handle under normal use conditions.
7. Why must ground conditions be evaluated before crane setup?
A. To improve fuel efficiency
B. To determine paint wear
C. To ensure proper load distribution
D. To check radio signal strength
Answer: C
Rationale: Stable ground is critical to distribute crane loads safely and
prevent tipping or sinking during operations.
8. What is the function of outriggers?
A. Increase engine speed
B. Stabilize and level the crane
C. Reduce fuel consumption
D. Control hydraulic pressure
Answer: B
Rationale: Outriggers extend the crane’s support base, increasing
stability during lifting operations.
