ABSTRACT:
A method for measuring the weight of a load loaded in a vessel of a vehicle such as, for example, a large-sized dump truck comprises steps of detecting the axial force applied to each of suspension cylinders mounted between the vehicle body frame and axles, and then compensating or correcting the detected axial force in accordance with respective mounting angles of links of linkage mechanisms mounted in the periphery of the axle and the inclination angle of the vehicle body. An apparatus for carrying the method into practice has at least four sets of suspension cylinders, an inclination angle detector mounted on the vehicle body frame, pressure sensors each being mounted on each of the suspension cylinders, a calculation or arithmetic unit adapted to receive and calculate output signals transmitted by the inclination angle detector and the pressure sensors, and a display unit adapted to receive a signal indicative of the result of calculation transmitted by the calculation or arithmetic unit and indicate it.
