ABSTRACT:
A weighing apparatus comprises a plurality of weighing apparatus modules, each of which includes an elongated platform structure under which lies an elongated frame structure. A load cell is interposed between a downwardly directed area of the platform structure and an upwardly directed area of the frame structure in the region of one end of both structures. A bracing arrangement, which resists relative horizontal movement of the platform and frame structures but permits relative vertical movement, includes a pair of parallel mechanical linkages, one of which is connected at one end to the platform structure adjacent the load cell and at the other end to the frame at a location spaced away from the load cell. For stability, the other mechanical linkage is connected in reverse fashion, namely, at one end to the frame structure adjacent the load cell and at the other end to the platform structure at a location spaced away from the load cell. Similar modules are assembled to form a single rectangular weighing apparatus, with one load cell at each corner by upper and lower tie plates which respectively link adjacent module frame structures and platform structures.
