The choker hitch WLL for this 5/16" Grade 100 Type CO single leg chain sling is 4,500 lbs. Under ASME B30.9, a chain sling used in a choker hitch is rated at 80% of its vertical WLL when the choke angle is 120 degrees or greater. This sling is rated 5,700 lbs vertical, and the OSHA chain sling tables list 4,500 lbs choked for this size and grade. If the choke angle is less than 120 degrees, capacity drops further, so the rating should come from the manufacturer or a qualified person. Always check the sling tag before the lift.
