ABSTRACT:
A low profile platform scale having a rigid rectangular platform and a base assembly, supporting the platform, adapted to rest on an underlying foundation and having four independent corner pads, each with beam load cells mounted in cantilever fashion on the corner pads, with the load cell elements coupled to the platform in an arrangement where the load on the platform is transmitted to the load cell elements by means of a tension member. The tension member is connected by ball and socket means to both the platform and the load cell element. The corner pads are connected to each other by slightly flexible, inelastic rods arranged beneath and adjacent borders of the platform in a rectangular array, and fastened to adjacent corner pads for fixing the spacing between them. The underlying corner pads operate independently and accommodate locally irregular surfaces causing any one of the corner pads to be slightly tilted without affecting the accuracy of response of the load cell. Tubular steel rods are used to connect adjacent corner pads providing conduits for conductors extending from the load cells to a junction box mounted on one corner of the platform.
