1. What is the primary purpose of a crane operator's pre-shift
inspection?
a. To determine the crane's resale value
b. To increase the crane's lifting speed
c. To identify conditions that could affect safe operation
d. To eliminate the need for maintenance
Rationale: A pre-shift inspection is intended to identify defects,
damage, leaks, abnormal wear, or other unsafe conditions before the
crane is placed into service. Early identification helps prevent
equipment failure, dropped loads, and injuries.
2. Before operating a crane, the operator should primarily verify
that:
,a. The crane is painted correctly
b. The load is always at maximum capacity
c. The crane is in safe operating condition and required inspections
have been completed
d. The boom is fully extended
Rationale: The operator must ensure that the crane is safe to operate
before beginning work. Required inspections, controls, safety devices,
and critical components should be checked according to applicable
requirements and the manufacturer's instructions.
3. What does a crane's rated capacity indicate?
a. The maximum speed of the crane
b. The weight of the crane itself
c. The maximum permissible load under specified operating
conditions
d. The minimum weight that must be lifted
Rationale: Rated capacity depends on factors such as boom length,
radius, configuration, and operating conditions. It is not simply a
single universal weight that can be lifted in every configuration.
4. Which document is especially important when determining
whether a planned lift is within the crane's capacity?
,a. Operator's personal résumé
b. Load chart
c. Equipment purchase receipt
d. Daily attendance sheet
Rationale: The load chart provides capacity information for different
configurations and operating conditions. The operator uses it to
determine allowable loads at particular boom lengths, radii, and
configurations.
5. What is the effect of increasing the load radius while keeping
other factors constant?
a. Crane capacity always increases
b. Crane stability always increases
c. Crane capacity generally decreases
d. Load weight becomes irrelevant
Rationale: As the horizontal distance between the load and the
crane's center of rotation increases, overturning forces increase. Load
charts therefore generally show reduced allowable capacity at greater
radii.
6. What is the safest practice when the operator cannot clearly see
the load?
, a. Continue lifting at full speed
b. Guess the load's position
c. Use a qualified signal person or an appropriate communication
system
d. Have several people give simultaneous signals
Rationale: The operator must have reliable information about the
load and its movement. When direct visibility is obstructed, an
authorized signal person or reliable communication system should be
used.
7. What should an operator do if a signal is unclear or contradictory?
a. Follow the loudest signal
b. Continue the lift slowly
c. Stop the operation until the signal is clarified
d. Follow the signal from the newest worker
Rationale: Ambiguous signals create a significant risk of unintended
movement. The operator should stop and obtain a clear, understood
instruction before proceeding.
8. Which person normally has authority to give routine crane
signals?
