摘要： A gantry crane system includes a frame structure having a plurality of vertical support legs and one or more members interconnecting predetermined pairs of the vertical support legs; and a positioning system including positioning sensors mounted to the frame structure and configured to receive positioning signals from positioning transmitters and a position processing unit configured to use the positioning signals to determine a deflection from vertical of at least one of the vertical support legs. In certain embodiments, the gantry crane system further includes a grappler assembly mounted to the frame structure. The position processing unit is configured to use the positioning signals to determine a location of the grappler assembly.
