ABSTRACT:
A counterbalanced lifting beam designed to lift and permit balancing of heavy loads. The lifting beam includes an internal counterweight that is adapted to be hydraulically adjusted by use of a manually operated control mechanism. The lifting beam also includes a rigid elongated lifting tower to add stability to the lifting beam and includes a centralized storage cabinet, which stores control mechanism and increases the weight concentration and the overall stability of the beam. Storage batteries and hydraulic control equipment are fully encased in the storage cabinet. As the lifting beam is held by the crane cable and a swivel, the beam can be moved in three dimensions.
