Prep & Study Guide
1. A crane operator is preparing to lift a load whose weight is known, but the
load center of gravity is offset from the centerline of the lifting points.
What is the primary concern?
A. The crane will automatically derate itself
B. The load may tilt or rotate unexpectedly
C. The boom angle will automatically increase
D. The hoist line will become shorter
Answer: The load may tilt or rotate unexpectedly
Rationale: An offset center of gravity can cause the load to shift, tilt, or rotate as
soon as it leaves the ground. The operator and lifting crew must account for the
center of gravity and rigging arrangement before the lift.
2. Which factor generally has the greatest effect on crane stability when a
load is positioned near maximum radius?
A. Engine temperature
B. Windshield condition
,C. Load radius
D. Fuel level
Answer: Load radius
Rationale: Increasing the horizontal distance between the load and the crane's
tipping axis substantially increases overturning moment. Load radius is
therefore a critical factor in determining rated capacity.
3. A crane's load chart lists different capacities for different boom lengths and
operating radii. Why must the operator use the chart corresponding to the
actual configuration?
A. Load charts are interchangeable
B. Capacity changes with crane configuration
C. Only boom length affects capacity
D. The chart is used only for maintenance
Answer: Capacity changes with crane configuration
Rationale: Crane capacity depends on boom length, radius, counterweight,
outrigger configuration, jib configuration, reeving, and other factors. Using the
wrong chart can result in a dangerous overload.
4. Before beginning a lift, the operator notices that the crane is positioned on
recently backfilled soil. What should be done?
A. Proceed if the ground looks level
B. Increase the lifting speed
C. Verify that the supporting surface can safely support the crane and imposed
loads
D. Reduce the load by exactly 5 percent
Answer: Verify that the supporting surface can safely support the crane and
imposed loads
,Rationale: Backfilled or disturbed soil may have inadequate bearing capacity.
Ground conditions must be evaluated and appropriate mats, blocking, or other
support provided when necessary.
5. What is the primary purpose of crane outriggers?
A. Increase engine horsepower
B. Reduce hydraulic pressure
C. Increase the crane's effective stability and distribute support reactions
D. Prevent the boom from telescoping
Answer: Increase the crane's effective stability and distribute support reactions
Rationale: Properly deployed outriggers expand the crane's support base and
transfer loads to the supporting surface. They must be fully configured
according to the manufacturer's requirements and the applicable load chart.
6. A load chart specifies that a crane's capacity is lower when operating over
the side than over the rear. What does this demonstrate?
A. Crane capacity can vary by operating quadrant
B. Rear operation is always prohibited
C. The boom is defective
D. The load chart is optional
Answer: Crane capacity can vary by operating quadrant
Rationale: Structural stresses, stability characteristics, counterweight
arrangement, and chassis design can cause different capacities in different
working areas.
7. What is the best method for determining the gross load that will be
imposed on a crane?
A. Use only the weight printed on the load
B. Add the load weight to applicable below-the-hook equipment and other
suspended components
, C. Estimate the weight from the load's appearance
D. Use the crane's maximum capacity
Answer: Add the load weight to applicable below-the-hook equipment and
other suspended components
Rationale: Gross suspended load can include the object, hook block, overhaul
ball, slings, shackles, spreader beams, lifting devices, and other components
that are supported by the crane.
8. Why is side loading of a crane boom generally prohibited?
A. It improves boom capacity
B. Booms are primarily designed for axial loading and specified load paths
C. It reduces radius
D. It increases allowable wind speed
Answer: Booms are primarily designed for axial loading and specified load paths
Rationale: Applying significant lateral force can create bending stresses for
which the boom was not designed. Loads should remain within the
manufacturer's permitted operating geometry.
9. During a lift, the load begins rotating unexpectedly. What is the safest
immediate response?
A. Accelerate the hoist
B. Attempt to stop the rotation with a sudden crane movement
C. Control the load carefully and use an appropriate tag line when conditions
permit
D. Release the load
Answer: Control the load carefully and use an appropriate tag line when
conditions permit
Rationale: Sudden crane movements can amplify load swing and dynamic
forces. Tag lines and controlled movements can help manage rotation when
they can be used safely.
