Abstract

A load-leveling hanging apparatus and a system for suspended lifting of objects are disclosed. The load-leveling hanging apparatus includes a carriage suspended from a line; a hanging beam adapted for attachment of multiple objects at points along the beam; a mechanism for moving the hanging beam relative to the carriage to thereby achieve a level condition; and a level indicator. The mechanism is a rotatable screw. The system includes the load-leveling hanging apparatus and a lifting device. The lifting device includes a drum for winding and unwinding a line; a motor coupled to the drum to apply a torque thereto; a guide to direct the line onto the drum; and a controller. The lifting device raises and lowers the suspended hanging apparatus.
