Abstract

A weighing system has a base (104), a platform structure (108), and a plurality of load cell assemblies (204). The platform structure (108) is movable with respect to the base and includes a planar top surface (180) defining a horizontal plane. Each of the plurality of load cell assemblies includes an upper portion supported by the base and a lower portion supporting the platform structure. Each of the plurality of load cell assemblies is positioned such that when the upper portion of each of the plurality of load cell assemblies is projected onto the plane and the planar top surface is projected onto the plane, each of the projected upper portions is located outwardly of the projected planar top surface. A load on the planar top surface is therefore located between the load cell assemblies. Sheet 5 of 13 c (0 , C,4 O~rC

A weighing system has a base (104), a platform structure (108), and a plurality of load cell assemblies (204). The platform structure (108) is movable with respect to the base and includes a planar top surface (180) defining a horizontal plane. Each of the plurality of load cell assemblies includes an upper portion supported by the base and a lower portion supporting the platform structure. Each of the plurality of load cell assemblies is positioned such that when the upper portion of each of the plurality of load cell assemblies is projected onto the plane and the planar top surface is projected onto the plane, each of the projected upper portions is located outwardly of the projected planar top surface. A load on the planar top surface is therefore located between the load cell assemblies.
