ABSTRACT:
A reduced-pivot assembly for supporting one end of a load for movement along a track in which a load support member for receiving that end is supported on a truck for lateral movement relative to the way. A limit switch mounted along the longitudinal center line of the truck at a location corresponding to a desired pivot center spaced from the load support center senses the lateral deviation of an adjacent portion of the load support member and actuates lateral shifting apparatus to shift the load support member in such a direction as to achieve the desired pivot center. A plurality of such sensors are disposed at longitudinally spaced locations on the truck to permit variation of the desired pivot center while moving along a track. Other sensors responsive to the lateral movement of the load support member inhibit the operation of the lateral shifting apparatus whenever the lateral displacement of the load support member exceeds a predetermined safe limit.
