WEIGHING DEVICE WITH CANTILEVER WEIGHING CELLS

A scale for weighing heavy loads comprising a horizontally disposed frame structure in which a load platform is horizontally supported by load cells at least at three points. The peripheral outline of the platform is such that it can be laterally and vertically displaced within the frame structure. The load cells include strain gauges each of which comprises a first and a second elongate member. The first member is fixedly secured to one end of the second member in a parallel aligned relationship therewith. One member of each strain gauge is secured to the frame structure and the other supports the platform. The members in the strain gauges are free to bend in response to a load placed upon the platform and such bending sets up corresponding potentials which are indicative of the load and are measured by suitable measuring means. Moreover, between some of the strain gauges and the platform are abutting bearing means so constructed that lateral movements of the platform cause vertical movements of the platform.
