ABSTRACT:
The present invention provides a load adjusting device for use with a hoisting unit. The device includes a load spreader or spreader bar supported from a single lift point hoist by a load leveling assembly that provides an ability to adjust the location of the single lift point with respect to the spreader bar. A roller support device allows the location of the single lift point to be accurately positioned along the spreader bar. Changing this position provides an attitude adjustment of the load about a horizontal pitch axis perpendicular to the spreader bar. At both ends of the spreader bar end lifting elements support the load from a plurality of transfer linkages associated with the load. The end lifting elements have load supports and adjustors that allow the load to be biaxially adjusted about both the horizontal pitch axis, as well as a horizontal roll axis parallel to the spreader bar.
