Claims

[Scope of utility model registration request]

A loaded weight measuring device that is attached to a cargo handling machine, comprising a working machine body that drives an attachment mounting seat up and down, and a work attachment that is attached to the attachment mounting seat and performs cargo handling work, the device comprising:
A parallel double beam formed by fixedly joining both ends of two vertically arranged elastic beams to each other by a pair of rigid bodies, a plurality of strain gauges attached to each of the elastic beams to form a bridge circuit, and the pair of rigid bodies. A loading weight measuring device for a cargo handling machine, comprising a main body mounting part and an attachment coupling part, which are respectively provided on the attachment mounting seat and the work attachment.
