Patent ID: 7874439

Claim:
An overhead crane adapted to be supported by first and second main support beams that are spaced apart and generally parallel, the overhead crane comprising: a bridge adapted to travel in a substantially horizontal direction along the main support beams; a trolley adapted to travel in a substantially horizontal direction along the bridge; a rotate bearing mounted to the trolley; a horizontally extending jib secured to the rotate bearing so that the jib is secured against movement relative to the rotate bearing and is rotatably coupled to the trolley so that the jib can rotate relative to the trolley; wherein the jib has a length shorter than the spacing between the main support beams; a first hoist adapted to travel in a substantially horizontal direction along the jib past the rotate bearing and having a load hook vertically movable relative to the jib; a second hoist coupled to the jib at a fixed position along the jib and having a load hook vertically movable relative to the jib; and wherein an end of the jib is movable by the trolley beyond the bridge and the main support beams so that the first hoist can be positioned on the end of the jib outside a perimeter defined by the first and second main support beams to lift a load located outside the perimeter without side loading the crane.
