A scale assembly includes a plurality of force measuring transducers which are connected with an improved platform. The platform has an upper portion which withstands compressive stresses and a lower portion which withstands tensile stresses during the weighing of a load. The upper portion of the platform includes a body of concrete having a corrugated lower major side and a flat upper major side which receives a load to be weighed. The lower portion of the platform includes a metal structure having a plurality of elongated ribs which are disposed in abutting engagement with the corrugated lower major side of the body of concrete. The ribs are connected with a bottom plate which cooperates with the ribs to form elongated cavities. At least a major portion of each of the cavities is disposed within the spatial envelope of the body of concrete to minimize the mass of the concrete. During the weighing of a load, the concrete is subjected to compressive stresses and the bottom plate and ribs are subjected to tensile stresses.

Scale assembly with improved platform

A scale includes a movable platform which is supported by a plurality of improved force transmitting assemblies. Upon sideways movement of the platform, the force transmitting assemblies and platform interact to align the force transmitting assemblies and to center the platform. Each force transmitting assembly includes a slider which is movable along a base surface. A rocker pin transmits force between the slider and a load cell beam which is connected with the platform. When the platform is moved sideways relative to the base, the rocker pin is tilted to a maximum offset position in which horizontally offset vertical force components are applied to the rocker pin. In accordance with the present invention, stop surfaces on the slider and load cell beam are disposed in abutting engagement when the rocker pin is in a maximum offset position.
