FIELD: machine building. ^ SUBSTANCE: devise consists of cross bar of crane, of load transporting mechanism, of weight measuring unit with power measuring strain sensors of weight loads, of converting unit electrically connected with power measuring strain sensors and of light display of weight loads readings. Also, the device has two weight measuring units and a beam connecting them. Each weight measuring unit consists of the strain sensor whereto brackets are connected from above and beneath. In the brackets there are inserted rings and a lower ring is set on an axle of a hoisting unit of the crane cross bar, while an upper ring is set on axle of the device beam. A secondary converter connected with LED display reflecting values of a current load is arranged on the device beam. ^ EFFECT: increased reliability of device operation, upgraded accuracy of measurement and simplified deign of device. ^ 5 cl, 4 dwg |
