ABSTRACT:
In a bridge crane, a rigid rectangular crane bridge frame is supported on a main runway by a truck at each corner, and in order to eliminate loadings on the trucks due to distortion of the runway, the trucks on one side of the bridge support the bridge frame through interlinked levers forming part of an equalizing linkage.
