2. A ship-to-shore gantry crane is being used to unload a vessel. What component attaches
directly to the container for lifting?
A) Boom
B) Hoist
C) Spreader

3. During lifting operations, which factor most affects crane stability and tipping risk?
A) Paint condition of the crane
B) Wind speed and load radius
C) Operator’s shift schedule
D) Type of radio used for communication
, Page 3 of 145
Correct answer: B
Stability is primarily influenced by wind forces and load radius, which change the crane’s center
of gravity and tipping risk.
4. According to OSHA, which physical condition may disqualify an employee from operating a
crane or power-operated cargo handling apparatus?
A) Corrected vision using eyeglasses
B) Controlled high blood pressure
C) Epilepsy or similar ailments that may suddenly incapacitate the employee

, Page 4 of 145
A) Increase engine power during lifting
B) Secure containers to the lifting equipment or to each other to prevent shifting
C) Measure the weight of the container automatically
D) Reduce fuel consumption during travel
Correct answer: B
Twist-locks secure containers to lifting equipment or to each other to prevent shifting during
handling and transport.
6. An operator hears a continuous audible alarm while operating a crane. According to standard
safety practices, what should the operator do?
A) Ignore the alarm and continue working
B) Acknowledge the alarm and complete the current lift
C) Immediately stop all operations and identify the cause
D) Increase engine speed to reset the alarm system
