1. Which of the following is the primary purpose of rigging
hardware?
A. To paint the load
B. To lift, move, or support a load safely
C. To increase the speed of a crane
D. To provide electrical grounding
B. To lift, move, or support a load safely
Rationale: Rigging hardware, such as slings, shackles, and hooks, is
designed to safely lift, move, or support loads. Its purpose is not
decorative or unrelated to load handling.
2. What is the primary consideration when selecting a sling for a lift?
A. Color of the sling
B. Sling capacity relative to the load weight
, C. The operator's preference
D. The temperature of the room
B. Sling capacity relative to the load weight
Rationale: Selecting a sling depends on its working load limit and the
weight of the load. Choosing the proper capacity ensures safety
during the lift.
3. Which factor does NOT affect the capacity of a sling?
A. Sling angle
B. Load weight
C. Sling material
D. Operator’s experience
D. Operator’s experience
Rationale: Sling capacity is determined by physical properties such as
angle, material, and load weight, not by the operator’s skill, though
skill affects safety.
4. What is the recommended sling angle range to maximize lifting
efficiency?
A. 0–30 degrees
B. 30–90 degrees
C. 90–120 degrees
D. 0–90 degrees
,B. 30–90 degrees
Rationale: Sling angles less than 30 degrees can significantly increase
tension in the sling, leading to unsafe loads. Angles between 30 and
90 degrees are considered safe for lifting.
5. Before each use, slings should be inspected for:
A. Only fraying
B. Any signs of wear, damage, or deformation
C. Color fading
D. Brand labels
B. Any signs of wear, damage, or deformation
Rationale: A thorough inspection ensures slings are free from defects
that could compromise safety.
6. A synthetic sling should NOT be used if it has:
A. A slight color change
B. A cut, tear, or chemical damage
C. Minor dust accumulation
D. Been stored in a dry, cool area
B. A cut, tear, or chemical damage
Rationale: Damage such as cuts, tears, or chemical exposure can
drastically reduce the sling's strength and create a safety hazard.
, 7. What is the function of a shackle in rigging?
A. To paint the load
B. To connect slings to the load or lifting device
C. To measure load weight
D. To lubricate the sling
B. To connect slings to the load or lifting device
Rationale: Shackles are hardware components used to attach slings to
loads or lifting devices, ensuring secure connections.
8. The working load limit (WLL) of a sling is:
A. The minimum load the sling can lift
B. The maximum safe load the sling can handle
C. The average weight the sling can support
D. The total weight of the sling
B. The maximum safe load the sling can handle
Rationale: The WLL is the maximum load a sling can safely lift under
ideal conditions, including correct angles and attachments.
9. What should be done if a sling becomes twisted during a lift?
A. Continue lifting slowly
B. Adjust or untwist the sling before continuing
C. Cut the sling
D. Increase the load slowly
