1. What is the primary purpose of a pre-use inspection of rigging
equipment?
A. To determine the manufacturer's production date
B. To increase the rated capacity
C. To identify defects or conditions that could make the equipment
unsafe
D. To eliminate the need for periodic inspections
Answer: C. To identify defects or conditions that could make the
equipment unsafe
,Rationale: Pre-use inspections help identify damage, wear,
deformation, contamination, or other conditions that could
compromise safe operation.
2. Who is responsible for ensuring that rigging equipment is used
within its rated capacity?
A. The truck driver
B. The qualified/competent personnel responsible for the lift
C. The warehouse clerk
D. The equipment manufacturer only
Answer: B. The qualified/competent personnel responsible for the
lift
Rationale: Lift personnel must verify that equipment is appropriate
for the load and configuration and is not overloaded.
3. What does WLL generally mean?
A. Working Load Limit
B. Wire Length Load
C. Weight Loading Level
D. Working Line Length
Answer: A. Working Load Limit
Rationale: WLL is the maximum load that a rigging component is
intended to support under specified conditions.
4. A sling's capacity is affected by which factor?
A. Hitch configuration
B. Sling angle
,C. Load contact conditions
D. All of the above
Answer: D. All of the above
Rationale: Sling capacity can change significantly depending on
configuration, angle, bending, connection method, and load-contact
conditions.
5. What should a rigger do if a sling has an illegible or missing
identification tag?
A. Use it at half capacity
B. Estimate its capacity from appearance
C. Remove it from service until its capacity can be verified
D. Use it only for personnel lifting
Answer: C. Remove it from service until its capacity can be verified
Rationale: Without reliable identification, the sling's rated capacity
and material specifications may not be established.
6. What is the safest action when a rigging component is suspected
of being damaged?
A. Continue using it for light loads
B. Paint over the damage
C. Remove it from service and have it evaluated
D. Increase the number of workers handling it
Answer: C. Remove it from service and have it evaluated
Rationale: Suspected damage should be addressed before the
component is exposed to lifting loads.
, 7. What is a sling angle?
A. The angle between the sling and the load
B. The angle between two cranes
C. The angle of the crane boom only
D. The angle between the hook and block
Answer: A. The angle between the sling and the load
Rationale: Sling-angle calculations are commonly based on the angle
between the sling leg and the horizontal or between sling legs,
depending on the convention used.
8. As the angle of a two-leg sling decreases from horizontal, sling-
leg tension generally:
A. Decreases
B. Increases
C. Remains unchanged
D. Becomes zero
Answer: B. Increases
Rationale: A shallow sling angle produces greater tension in each
sling leg for the same load.
9. Which sling angle generally produces the greatest tension in the
sling legs?
A. 90° from horizontal
B. 60° from horizontal
C. 45° from horizontal
D. 30° from horizontal
Answer: D. 30° from horizontal
