a weighing
scale for weighing, individually, the loads on each of the wheels of sets of wheels which are mounted on an axle of a moving vehicle, for example, a truck. The wheels are in side-by-side relationship at either end of each axle and move along a surface plane in a direction transverse to the axis of the axle. The
scale includes a weighing beam supported in the surface plane and having at least one side edge at an oblique angle to the direction of travel. Weight detectors underlie and support the weighing
scale beam and comprise the sole support of the weighing beam. In one embodiment, the weighing beam is rectangular in shape and there is a weight detector at either end of the beam. In a further embodiment, the weighing beam is triangular in shape and there is a weight detector at each corner of the weighing beam. In a still further embodiment, a
scale wheel position detector is provided to detect that a wheel is at a weighing position on the beam or about to arrive at this position.
