Abstract
The load measuring apparatus for a working machine includes a front load acquisition unit that acquires a front load applied to front suspension cylindersAl,Ar, a rear load acquisition unit that acquires a rear load applied to rear suspension cylindersBl,Br, a surface resistance detection unitthat detects a surface resistance of a travel road for a dump truck, an adderthat based on the front load acquired by the front load acquisition unit and the rear load acquired by the rear load acquisition unit, computes a total load acting on the suspension cylindersAl,Ar,Bl,Br to determine the load of a cargoA, and a total load correction unitthat corrects the total load, which has been computed by the adder, according to the surface resistance detected by the surface resistance detection unit
