PURPOSE:To prevent a vehicle body from overturning by an unbalanced load due to a working load, by actuating a safety device when a load difference between the right and left of the titled vehicle becomes more than a predetermined value by detecting a load of a running device. CONSTITUTION:Load sensors 13a-13d are provided on running devices 1, 2 longitudinally and laterally, and a lateral load difference of more than a predetermined value is detected by comparison circuits 16a, 16b. A longitudinal load difference is detected also by averaging circuits 20a, 20b and a comparison circuit 21. Based on a detected result, a driver is alarmed by operating a buzzer 19. Overturning can be prevented reliably as not only an inclination of a vehicle body but also an unbalanced load due to a working load is detected. |
