ABSTRACT:
A load cell weighing apparatus (1) includes a base (7) and a load plate (11) and a load cell (9) mounted between the two. The base (7) includes four load arrestors (17) capable of precise adjustment. Each load arrestor (17) has a pin support (18) with three vertical holes (19) of different depths and a pin (21) which is placed in one of the holes (19). The load arrestors (17) prevent damage to the load cell (9) by limiting vertical movement of the load plate (11) with respect to the base (9). The amount of relative movement is easily and quickly adjusted by simply repositioning the pins from holes of one depth to holes of another depth.
