PROBLEM TO BE SOLVED: To prevent seizure of the engine of a working vehicle even on an acute slope, by rotating the support base of the engine by a rotary structure fitted to the body of the driving vehicle on the slope to always position the engine horizontally. SOLUTION: The wires 34 of the right and left winches 31 of a working vehicle 59 on a slope are fixed to anchor pins 35 and the wheels 7 are rotated by driving hydraulic motors 6 for the wheels while winding up the wires 34 and transferred. In this time, the height of the vehicle body 1 can be arbitrarily adjusted by the hydraulic cylinder for the wheels. When the wheels 7 are derailed out of a slope frame 2, the front and rear rollers 11, 12 preventing the wheels from getting out of place come in contact with the slope to prevent the inclination of the vehicle body 1. When the vehicle body 1 travels on the slope frames 2, 3 on the slope, the hydraulic cylinder 30 of the support device 16 of the working base is actuated to position the working base 15 nearly horizontally and hence, the seizure of the engine 37 can be prevented. |
