1. What is the primary purpose of a crane’s load chart?
a. To show the crane’s fuel capacity
b. To indicate the crane’s required maintenance intervals
c. To specify lifting capacities under various configurations
d. To show recommended operator certifications
Answer: c
Rationale: Load charts define safe lifting capacities based on boom length,
radius, and configuration.
2. The capacity of a crane decreases as the load radius:
a. Decreases
b. Stays constant
c. Is eliminated
d. Increases
Answer: d
Rationale: Greater radius increases leverage on the crane, reducing
capacity.
3. Which signal must be used to stop crane operations immediately?
a. Dog everything
b. Lower slowly
c. Emergency stop
d. Travel
Answer: c
,Rationale: “Emergency stop” is the universal signal to halt all crane
movements.
4. Boom deflection during a lift will:
a. Decrease load radius
b. Increase load radius
c. Have no effect
d. Improve stability
Answer: b
Rationale: Deflection pushes the boom outward, increasing radius and
reducing capacity.
5. What is the most important factor when determining ground support
for a crane?
a. Surface color
b. Soil bearing capacity
c. Weather forecast
d. Operator experience
Answer: b
Rationale: Adequate ground bearing prevents outrigger or crawler
collapse.
6. Outriggers must be:
a. Used only on uneven terrain
b. Fully extended and set per manufacturer instructions
c. Optional for all lifts
d. Used only in windy conditions
Answer: b
Rationale: Outriggers must be fully deployed per the load chart
requirements.
7. Leveling a crane is critical because:
a. It improves visibility
b. Load charts assume a level crane
c. It requires less fuel
, d. It centers the hook
Answer: b
Rationale: Crane capacities are based on level conditions; out-of-level
increases risk of tip-over.
8. When lifting personnel with a crane, the platform must be:
a. Homemade but stable
b. Designed and approved for personnel lifting
c. Constructed from chain slings
d. Allowed to free-swing
Answer: b
Rationale: OSHA requires personnel platforms engineered and approved
for lifting.
9. The term “dynamic loading” refers to:
a. A stationary load
b. A load that changes the crane’s engine RPM
c. Forces created by load movement, wind, or sudden stops
d. A crane’s computer system
Answer: c
Rationale: Dynamic forces add stress beyond static weight.
10. A tag line is used to:
a. Increase crane boom length
b. Control load rotation
c. Increase load weight
d. Secure boom pins
Answer: b
Rationale: Tag lines prevent uncontrolled load spinning.
11. Anti-two-block devices prevent:
a. Boom extension
b. Hook drift
