ABSTRACT:
A compression cap assembly for the end of a spreader bar or pipe used in lifting heavy loads with a crane includes a compression plate, spaced-apart plate members on the outer side of the compression plate that carry upper and lower pins that extend through loops on the ends of cables, and semicircular coupling members on the inner side of the compression plate that receive an end portion of the spreader pipe. The coupling members having clearance between the adjacent edges thereof, and fasteners are used to reduce the clearance and cause the coupling members to tightly clamp and grip such end portion.
