Abstract

A removable hoist assembly for lifting a load up and into a confined space in the form of a kit has a support structure releasably coupled to overhead structural beams in the confined space, a motor releasably coupled to the support structure above the support structure between the overhead structural beams, a hoist arm releasably coupled to the support structure to be rotatable and extendable with respect to the support structure, and a cable supported by the hoist arm. The cable has a free end positioned proximate a distal end of the hoist arm and configured to couple to the load and a terminal end coupled to the motor such that the cable extends and retracts with respect to the motor. The hoist arm support structure spreads the weight of the motor, hoist arm and the load across a plurality of the overhead structural beams.
