Abstract

See full text

In the crane industry, there is a need to efficiently attach, move, and unattach loads to crane hooks. When the load has an asymmetrical center of gravity, two cranes are often used to move the load. In the specification and drawings a spreader bar assembly is described and shown with at least two longitudinal members having a length; a plurality of cross members each attaching to at least two longitudinal members; and a plurality of support means adjustably positioned along the length of the longitudinal members. In a preferable embodiment of the invention, a single crane uses a spreader bar assembly to move a load having an asymmetrical center of gravity.
