PURPOSE:To eliminate the need for fundation work which costs fabulously, by detecting shearing stress that a wheel to be measured gives to a track through a shearing stress detector provided to the side of the track, and calculating vehicle weight and loading weight on the basis of the signal of the detector. CONSTITUTION:A stop position detector 4 detects a wheel to be measured of a vehicle on a track 2 being at a prescribed measurement position when the wheel is at a still. Shearing stress detectors A and B detect shearing stress that the wheel to be measured gives to the track 2. Output signals of the detectors A and B are amplified by amplifiers 17 and 18, whose outputs are sent to a mean value arithmetic circuit 19 which calculates the mean value of a load on the track 2, and the resulting signal is outputted to an arithmetic circuit 20 for the weight (w) of loaded metal. A circuit 22 for calculating the total weight W of a metal mixer car 1 adds the output signal (w) of the circuit 20 to the weight W0 of the unloaded metal mixer car 1. |
