ABSTRACT:
A vehicle platform scale includes a weighbridge platform mounted on transversely positioned load cell assemblies. Each load cell assembly includes a deflectable, floating load cell and associated strain gauges mounted in a load cell tray. Each load cell rests at its opposite ends on a pair of freely mounted bearing rods retained in fixed positions with respect to one another and with respect to the load cell by cooperable grooves in the bottom surface of each end of the load cell. Weight load from the overlying weighbridge platform is transmitted to the middle portion of the load cell through a pair of load cell buttons affixed to the upper surface of the load cell. The load cell is retained in the load cell tray against upward displacement during handling or lifting of the scale by a pair of top retaining plates overlying the ends of the load cell. The load cell is retained against lateral displacement within the load cell tray by a pair of neoprene rubber bumper plates at the opposite ends of the load cell. The load cell is further retained against displacement in the load cell tray along the axis of the weighbridge platform by four pins that protrude from the side walls of the load cell tray at positions centered on the axes of deflective rotation of the opposite ends of the load cell.
