WEIGHT-MEASURING GEAR Russian patent published in 2004 - IPC

FIELD: weighing of cargoes of special assignment, protection of cage of hoist against overload. SUBSTANCE: gear includes cargo platform with vertical column coupled to vertical bend of hoist boom with the aid of two parallel springy plates placed horizontally and mounted in horizontal plane, force measuring cell coupled to control system of hoist. Ends of springy plates are held rigidly and ensure only one degree of freedom of cargo platform with movement in vertical plane within sensitivity limits of force measuring cell. Case of force measuring cell is made fast to vertical column of platform. Sensitive element of force measuring cell is supported in cantilever and interacts with vertical bend of hoist boom through ball and adjustment bolt so that in operational state force measuring cell takes completely in weight of cargo platform, unloads platform from vertical forces. EFFECT: simplified design of weight-measuring gear, its raised accuracy and reliability in operation. 1 cl, 3 dwg
