Abstract

PROBLEM TO BE SOLVED: To provide a smoothly movable, safely and efficient working vehicle by constituting the working vehicle by a car body, a wheel driving device, a wheel slippage preventing roller, a work bench, and a rotating mechanism. SOLUTION: A slope working vehicle 58 is traveled by rotating a drive tire wheel by the drive of a wheel hydraulic motor 5. The height of a car body 1 is regulated by the operation of a wheel hydraulic cylinder 7. When the working vehicle is slipped, front and rear slippage preventing rollers 10, 11 make contact with a slope frame to prevent the inclination of the car body 1. When a work is performed on the slope frame of a slope, the wire of a winch 29 is mounted on an anchor pin fixed to the slope, and the drive tire wheel 6 is driven while winding the wire to climb the slope frame. At that time, a work bench rotating device hydraulic cylinder 28 is operated so that a work bench 14 is situated in substantially horizontal position. Then, hydraulic cylinders 54, 57 are operated, and the car body 1 is fixed by a car body locking device 51 to perform the work. Thus, the work can be safely performed on the work bench 14.
