ABSTRACT:
The invention comprises a load-supporting beam provided with plates at each end which are pivotally mounted to pendants at each end, to which pendants are attached the suspending cables. Each pendant carries a hydraulic cylinder attached at one end to the pendant and at the other end to a crank affixed to the rotating element carrying the pivot for the load. That element is provided with an indexing pin which fits movably in a slot in the adjoining beam end plate. That end plate also has a second slot in line with the slot first mentioned, through which second slot passes the pivot bolt which also passes through the center of rotation of the rotating member. The center of gravity of the rotating load carrier is brought into alignment with the axis of rotation by adjusting the position of the indexing pin and the pivot bolt in the end plate slots.
