Libra jig

Abstract

This product is a jig for a lifting beam used to hoist heavy, long, or irregularly shaped objects. The lifting beam is constructed by selecting a connection point provided in four horizontal directions and fastening a beam of appropriate length, inserted into the connection point, with bolts tightened through the holes in the connection point. This product can be used to construct a single-girder lifting beam by fastening two of these jig units to both ends of a single beam, or a multi-girder lifting beam by fastening four of these jig units, placed at the four corners, to a beam to form a frame.
