<p>An object of the present invention is to accurately measure a carrying weight of a vehicle on the basis of a force applied to suspension cylinders and allow an operator to accurately recognize the weight. A first force applied to a front wheel suspension cylinder of a vehicle carrying a load can be obtained on the basis of detection values of pressure sensors (2a, 3a, 2b, 3b), and a second force applied to a rear wheel suspension cylinder can be obtained on the basis of detection values of pressure sensors (2c, 3c, 2d, 3d). An inclination r of the vehicle in the longitudinal direction is detected by an inclinometer (8), and the first and the second forces are corrected in accordance with this inclination r. Further, the first and the second forces are corrected in accordance with the magnitudes of the first and the second forces to thereby obtain the weights of the vehicles on the front wheel side and the rear wheel side. Then, the weight of a vacant vehicle is subtracted from the sum of the weight on the front wheel side and the weight on the rear whell side, to thereby obtain the carrying weight . The carrying weight thus obtained is displayed on a display (24) screen in units varying in accordance with the change-over made by a switch (21). <IMAGE></p> |
