ABSTRACT:
The weigh scale incorporates a weighbridge, load cells and load cell mounting mechanisms for each load cell. The load cells are double ended shear beam type horizontally mounted directly under the main beams of the weighbridge with the ends of the load cells being rigidly secured to a load cell stand which in turn is supported upon the concrete base of the weigh scale location. The load is vertically applied to the load cell by means of a chair for each load cell and a link plate. Each of the sides or legs of the chair rest upon the supporting means of the link plate which in turn applies a vertical shearing force upon the load cell intermediate the ends thereof. The support points or areas of the link plate are located below the engagement point or area of the link plate upon the load cell and this permits free horizontal movement of the weighbridge longitudinally, but absorbs any side movement thereof without affecting the conventional electronic indicator to which the load cells are operatively connected.
