What is the reduction factor for a wire rope sling used in a choker hitch?

CQ-005 · Rigging
The reduction factor for a wire rope sling in a choker hitch is 0.75 or 75% of the sling's rated capacity.
Wire rope slings used in a choker hitch configuration experience a significant reduction in lifting capacity due to the sharp bend and compression forces created where the sling passes through itself. The standard reduction factor is 0.75, meaning the sling can only lift 75% of its rated working load limit when configured as a choker.
Reference: ASME B30.9 - Slings
Remember: "Choker Chokes at 3/4" - choker hitch reduces sling capacity to 75% (3/4 of rated capacity)
