Abstract

A rigging assembly has no loose parts that an up-rigger may drop. The rigging assembly includes a length of steel cable terminating in a loop at each end. One loop extends through an oblong master link, while the other loop extends through a swivel hook. The ground-rigger can attach the hook of a hoist's chain to the master link on the ground. The ground-rigger can then tie the up-rigger's rope onto the master link. The up-rigger then pulls the rigging assembly and the hoist's chain up to the beam, leaving the master link and chain under the beam. Then the up-rigger grabs the hook end of the rigging basket assembly, bends it over the beam, and attaches the swivel hook end to the master link, thus creating a loop around the beam to support the hoist's chain and load, which is known in the industry as creating a basket.
