ABSTRACT:
A means for protecting hoisting slings and/or their loads is described. The device includes a strip of uniform width and indefinite length comprising multiple plies of woven webbing, a plurality of spaced channels between a first pair of adjacent plies, and a plurality of friction straps, each secured at one end between a second pair of adjacent plies so that the opposed free end extends perpendicularly from a longitudinal edge of the strip. Each friction strap corresponds to one of the plurality of channels and is about as wide as its corresponding channel so that it fits snugly therein. The device is interposed between the sling and the load and is attached to the sling by encircling the sling cable with the straps and passing them through their corresponding channels so that the sling is firmly engaged by the device.
