ABSTRACT:
Weighbelt apparatus of the kind described in U.S. Pat. No. 4,509,609 is improved by having the planar support cantilevered to both sides of a central transverse crossbeam which rests on six cantilever arms carrying strain gauges in cutouts. Two calibrating weights can be hung independently off the bottom of the beam when the belt is lifted off the planar support. This configuration avoids spurious reading when the load on the belt is unevenly distributed.
