1. What is the primary purpose of the load chart on a crane?
A. To show the crane’s serial number
B. To display the manufacturer’s name
C. To specify the crane’s lifting capacity under various
conditions
D. To record daily inspections
Rationale: The load chart defines the maximum allowable loads
for different boom lengths, radii, and configurations—critical for
safe operations.
2. Before operating a crane, the operator should first:
A. Check the weather forecast
B. Conduct a pre-operation inspection
C. Test the horn only
D. Review the previous day’s notes
,Rationale: A full inspection ensures all safety systems and
components are functional before lifting begins.
3. What does "radius" refer to in crane operations?
A. The height of the boom
B. The horizontal distance from the center of rotation to the
load hook
C. The length of the wire rope
D. The counterweight distance
Rationale: The load radius determines the crane’s lifting
capacity; as the radius increases, capacity decreases.
4. When operating near power lines, OSHA requires a
minimum clearance of:
A. 5 feet
B. 10 feet for lines up to 50 kV
C. 15 feet
D. 20 feet
Rationale: OSHA mandates a 10-foot clearance for up to 50kV,
increasing with higher voltages.
5. The term “outriggers fully extended” means:
,A. The crane is resting on its tires
B. Outriggers are extended and properly set on pads or
cribbing
C. The boom is at maximum length
D. The crane is tilted
Rationale: Outriggers provide maximum stability by widening
the crane’s base and distributing weight.
6. What document must always be kept in the crane cab?
A. The operator’s paycheck
B. The crane load chart
C. Maintenance logs only
D. Daily job reports
Rationale: The load chart must be available and readable by the
operator during all operations.
7. Which factor most affects the crane’s rated capacity?
A. Tire pressure
B. Boom length and load radius
C. Operator weight
D. Wind speed under 5 mph
Rationale: Lifting capacity decreases as boom length increases
or the load radius extends.
, 8. What is the most common cause of crane tip-over
accidents?
A. Lack of lubrication
B. Overloading beyond rated capacity
C. Cold weather
D. Operator fatigue
Rationale: Exceeding rated load limits destabilizes the crane,
causing tip-overs.
9. Who is responsible for signaling during a lift?
A. The crane owner
B. The site supervisor
C. A designated qualified signal person
D. Any nearby worker
Rationale: OSHA requires that only a qualified signal person
direct crane movements to prevent miscommunication.
10. The term “boom angle” refers to:
A. The height of the cab
B. The angle between the boom and the horizontal plane
C. The load swing direction
D. The counterweight angle
