ABSTRACT:
An arcuate channel member has a detachable connection at mid length with an object to be lifted. The channel member provides a guide track for sliding movement of the lower portion of a flexible cable sling loop, the upper portion of which is lifted by a hook or grapple or the like. By sliding the loop in this guide track from time to time the lifting hook or grapple does not sharply bend the sling loop at the same point in every lifting operation, thereby greatly prolonging the life of the sling loop.
