Pivoting Hoist Ring has a low profile and high load capacity. It pivots a full 180 degrees, but does not rotate. Safety factor = 5:1. Any workholder weighing over 30 pounds should be fitted with hoist rings to allow them to be moved safely. Hoist rings are load-centering eyebolts. They are designed to be rigged from the center or the side and may pivot or swivel. Some hoist rings connect directly to webbing, chain, or shackles. Others have a hook-end rather than a standard bail, eye, or ring. There are three basic types of hoist rings: center-pull hoist rings, side-pull hoist rings, and screw-mount lifting rings. They have mounting holes for screws. In terms of movement, pivoting hoist rings have an eye that is designed to pivot 180°. Swiveling hoist rings are designed to swivel 360°. Always make sure the weight of the workholder is well within the rated capacity of the hoist ring. The specific style of hoist ring selected should be based on the work to be done.
