A wire rope sling is rated at 2 tons in a single vertical hitch. When rigged as a basket hitch with both legs hanging straight vertical (90° from horizontal), what is the rated capacity of the lift?
Answer: 4 tons
In a vertical basket hitch, the load is shared equally between two legs. Each leg can carry its full 2-ton rating, so total capacity = 2 × 2 = 4 tons. As the sling angle decreases from vertical, a derating factor applies.
Per ASME B30.9, a wire rope sling must be removed from service when it has:
Answer: Six or more randomly distributed broken wires in one rope lay
ASME B30.9 specifies immediate removal when there are 6 or more randomly distributed broken wires in one rope lay, or 3 or more broken wires in one strand of one rope lay. Surface rust alone is not an automatic disqualifier; a kink that cannot be straightened — not one that can — requires removal.
What does the abbreviation WLL on rigging hardware mean?
Answer: Working Load Limit — maximum load the component may handle in normal service
WLL (Working Load Limit) is the maximum load a piece of rigging hardware is designed to support under normal, intended conditions. It already incorporates the design factor of safety; it is NOT the breaking strength.
A chain hoist is designed to be used:
Answer: For vertical lifting only — never for side-pulling or tip-pulling
Chain hoists are engineered for pure vertical loading. Side-pulling or tip-pulling creates off-axis forces that overload the hook, frame, and load chain in ways the hoist was not designed to handle, and can cause catastrophic failure.
What is the primary purpose of a tagline during a crane or hoist lift?
Answer: To control the load's rotation and prevent uncontrolled swinging
Taglines are guide ropes that allow personnel to control a suspended load's orientation and prevent it from spinning or swinging into obstacles — without placing hands near the load or rigging. They do not bear the weight of the load.
Before beginning any rigged lift, the rigger must first:
Answer: Verify the exact load weight, inspect all rigging hardware, and confirm the lift plan with the team
Pre-lift planning is a mandatory safety step: determine exact load weight and center of gravity, inspect all slings and hardware for defects, confirm the rigging configuration is appropriate, and communicate the plan to everyone involved. Guessing weight or skipping inspection are leading causes of rigging accidents.
