Abstract
An end fitting for a lifting sling shaped so that the identical fitting can be used at both ends of the sling, because it is constructed so that an outside dimension will slip through the opening of the fitting. The opening is longer than the end fitting's width and has one end curved to accommodate a crane hook while the other end is straight so that the sling web can be attached there.
Claims4
An end fitting for a lifting sling comprising:
- a continuous planar structure, with its length dimension exceeding its width dimension, shaped to enclose an opening, with a first boundary of the opening being a straight surface so that a web will wrap around the straight surface and the adjacent part of the structure, and a second boundary of the opening, which is located opposite from the first boundary, being curved to accept a crane hook, the opening being dimensioned so that the longest dimension of the opening exceeds the dimension of the width of the planar structure;
- and
- two protrusions from the structure into the opening, the protrusions being located near the first boundary of the opening so as to limit the movement of a web which is wrapped around the first boundary.
