ABSTRACT:
A center-of-gravity shifting apparatus for attachment to a load-handling apparatus having a bail, a bearing attached to the bail, and a clamping portion for maintaining the bearing in a first position when a weight of a load-handling apparatus is exerted on the bearing. The first position corresponds to a location at which the bail is in line with a center-of-gravity upon lifting a load-handling apparatus. A cam follower connected to the bearing guides the bail from the first position to a second position which corresponds to a location at which the bail is in line with a center-of-gravity of the load-handling apparatus when lifting a load. A load-handling apparatus for lifting and maneuvering a load incorporating the center-of-gravity shifting apparatus, a control handle, and an end effector which includes a pair of forks. The forks may be formed from two U-shaped structures joined into a triangular bracing configuration by a crossbar attached between the forks.
