ABSTRACT:
A gantry crane has first and second side support frames spaced by a pair of trolley beams. A 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.
