Abstract:

A gantry crane has first and second side support frames spaced by a pair of trolley beams. A load lifting mechanism is connected to the trolley beams and includes a lift frame for engaging a load to be lifted. An operator cab is mounted on the first side support frame and is vertically moveable between a lowermost position and an uppermost position in an operational plane defined by the first side support frame. A cab lift cable has a length and a first end fixed to the operator cab and a second end fixed to the side support frame. A hydraulic cylinder urges the cable between its fixed first and second ends in a direction transverse to a portion of its length. In another embodiment of the invention, an operator cab is adapted to be horizontally moveable. The elevating operator cab of the present invention can be configured to move horizontally. The elevating operator cab is lifted by a carriage beam vertically moveable along vertical legs of the first side support frame.
