Abstract

See full text

A load cell includes a bearing element configured for a hoist that includes a hook, a suspension with an orifice that receives a shaft of the hook, a nut, and housing. The bearing element, preferably a ring, contacts the suspension, and has an orifice that receives the shaft therethrough with the nut secured to the shaft proximate to the bearing element. Strain gauges are mounted on the ring side wall being equally spaced. A second suspension orifice concentric with the first orifice receives the ring with strain gauges therein. For improved accuracy, a thrust roller bearing and two thrust washers are positioned on sides of the ring, all of which are preferably positioned in a cup member that is received in the second orifice. A clearance fit is provided with respect to each of protruding upper and lower overhanging cylindrical ring lips and the cup to protect the gauges.
