1. Before beginning a lifting operation, what is the operator's most important
responsibility regarding the crane's rated capacity?
A. Estimate the load weight from experience
B. Verify the load weight and configuration against the applicable load chart
C. Use the maximum capacity printed on the crane
D. Assume the capacity is unchanged regardless of boom length
Answer: B. Verify the load weight and configuration against the applicable load
chart
Rationale: The rated capacity depends on configuration, radius, boom length,
counterweight, attachments, and other factors. The operator must use the
correct load chart and determine whether the planned lift is within the crane's
permitted capacity.
, 2. A crane is positioned on a site where the ground appears firm but has
recently been backfilled. What should the operator do before lifting?
A. Proceed if the tires do not sink
B. Increase engine speed
C. Verify ground conditions and ensure adequate support for the crane
D. Reduce the load by 10 percent and proceed
Answer: C. Verify ground conditions and ensure adequate support for the crane
Rationale: Backfilled or disturbed soil can fail under concentrated outrigger or
crawler loads. Ground-bearing capacity and adequate support must be
evaluated before placing the crane under load.
3. When determining gross load for a crane lift, which item must generally be
included in addition to the lifted object?
A. Only the hook block
B. Only the rigging
C. The load and applicable below-the-hook equipment
D. Only the object's shipping weight
Answer: C. The load and applicable below-the-hook equipment
Rationale: The crane must support the total suspended load, including items
such as the hook block, slings, shackles, spreader beams, lifting devices, and
other applicable equipment.
4. What is the primary purpose of a crane's load chart?
A. To establish fuel consumption
B. To identify the manufacturer's permissible lifting capacities under specified
configurations
C. To determine the operator's maximum driving speed
D. To establish minimum inspection intervals
Answer: B. To identify the manufacturer's permissible lifting capacities under
specified configurations
,Rationale: Load charts provide capacity information for specific boom lengths,
radii, configurations, attachments, counterweights, and operating conditions.
5. A crane's radius increases while boom length and load remain unchanged.
What generally happens to available lifting capacity?
A. It increases
B. It remains exactly the same
C. It decreases
D. It becomes unlimited
Answer: C. It decreases
Rationale: As operating radius increases, the load moment increases, generally
reducing the crane's permissible capacity.
6. Which condition is most likely to produce a two-blocking hazard?
A. Excessive tire pressure
B. The upper block or overhaul ball contacting the boom tip or associated
components
C. Low hydraulic oil temperature
D. Excessive counterweight
Answer: B. The upper block or overhaul ball contacting the boom tip or
associated components
Rationale: Two-blocking occurs when the hook block, overhaul ball, or related
components contact the boom tip or upper block, potentially causing severe
damage or a dropped load.
7. What is the safest practice when the operator cannot see the load or
landing area?
A. Continue because the rigger can compensate
B. Operate according to memory
C. Use a qualified signal person or another approved communication method
D. Increase lifting speed
, Answer: C. Use a qualified signal person or another approved communication
method
Rationale: The operator must have reliable communication when the load path
or landing area cannot be directly observed.
8. During a lift, a signal person gives a stop signal while another worker gives a
conflicting signal. What should the operator do?
A. Follow the more experienced worker
B. Follow the signal that results in faster movement
C. Stop the crane movement
D. Ignore both signals
Answer: C. Stop the crane movement
Rationale: When conflicting signals occur, stopping the operation is the safest
response until communication is clarified.
9. What is the purpose of a boom angle indicator?
A. To measure wind velocity
B. To indicate boom angle relative to a reference plane
C. To measure sling tension
D. To calculate soil bearing pressure
Answer: B. To indicate boom angle relative to a reference plane
Rationale: Boom angle is an important factor in determining operating radius
and crane capacity on applicable load charts.
10.A load has a known weight of 18,000 lb, and the rigging and below-the-
hook equipment weigh 1,200 lb. What minimum total suspended load
should be considered before other applicable factors?
A. 18,000 lb
B. 18,600 lb
