PURPOSE:To improve safety, by a method wherein, in a truck in which coupling shafts are respectively provided between a front and a rear car body and a load-carrying platform and the rear car body, and the load-carrying platform is positioned rotatably about the two shafts, lateral inclination of the front car body forces a driver's part to be inclined in a horizontal direction from the load-carrying platform and the rear car body. CONSTITUTION:When a vehicle runs to a lateral sloped ground during straight running under a loading state, a driver's part 1 is laterally inclined from a sideways horizontality through a front car body 6. A current inclination angle with a ground is detected by a sensor 22 to output the result to a controller. The controller, simultaneously, inputs a car speed also. The controller controls expansion and contraction of an expandable cylinder 10 by means of the two input signals, and right before rear wheels 31 are rolled to the lateral inclination ground, the load-carrying platform 3 is turned about front and rear coupling shafts 5 and 9 to take a sideways horizontal orientation. This enables the direction of the centre of gravity of a load to stay in the vicinity of a machine centre on the safety side, and permits improvement of safety. |
