Abstract
A load measuring device for a construction machine includes a processing unit for acquiring signals indicative of cylinder pressure of front and rear suspension cylinders via pressure sensors and computing a weight value of a load put on a dump body of the construction machine. When the construction machine is traveling on a curvilinear route, the construction machine makes the output of the weight value ineffective. In particular, when the differential speed value between the rear wheels, received from a speed difference detector, is below a preset value, the arithmetic unit outputs a loading weight W computed by the processing unit, as final loading weight, and so that when the differential speed exceeds the preset value, the arithmetic unit makes ineffective the computed loading weight W as the final loading weight output.
