PURPOSE:To surely change an attitude of a rear body, at running of a truck on sloped land when its cargo is prevented from falling off to tilt the rear body with respect to a car body and substantially change the attitude to a horizontal position, by detecting a sloped condition of the rear body on the basis of change of a position in the center of gravity of the rear body. CONSTITUTION:Load cells 10a, 10b, detecting weight of a cargo on a rear body 9, are provided respectively in front and rear parts of the dumping rear body 9, on the basis of information from those cells, a decision is indicated for a position of the center of gravity of the cargo with respect to the rear body 9 whether within a preset range in the longitudinal direction or either in front or rear of the range. A control circuit, operated by a controller 11 and provided for cylinders 4, 7 to tilt the rear body 9 toward or rear, is constituted by providing the first and second solenoid valves 15a, 15b. When the position of the center of gravity of the cargo is moved rearward at ascent running, the cylinder 4 is operated through the solenoid valve 15a, on the contrary, when the position of the center of gravity is moved forward at descent running, the cylinder 7 is operated through the solenoid valve 15b. |
