ABSTRACT:
A platform scale with a load platform (7) for receiving articles to be weighed, wherein the load is transmitted to a force sensor by force-transmitting arms (5), and is supported at each of its four corners by a respective single-piece force-transmitting member (2) via a respective load-bearing column (8). Force-transmitting member (2) comprises a fixedly disposed anchoring member (22), a load-bearing member (12) guided for parallel movement with respect to the anchoring member (22) by link members (10, 17), and a lever member (14) suspended between anchoring member (22) and load-bearing member (12) by two thin strips (13, 15) whereby the fulcrum of the lever member is formed by a thin strip (13), and lever member (14) transmits a torque, corresponding to the load, to force-transmitting arm (5).
