Abstract

PROBLEM TO BE SOLVED: To provide a slope working vehicle which can safely and smoothly travel without undergoing large resistance, even on a sharp inclined slope surface while preventing its front end portion from falling down while levitated, and can be efficiently prevented from toppling over to the rear when it assumes a working position. SOLUTION: The slope working vehicle is comprised of a working vehicle main body, a wire fairlead, hanging tools, and a wire upward/downward moving mechanism. The working vehicle main body can travel on a slope surface. The wire fairlead is attached to a front portion of the working vehicle main body. the handing tools are formed of winches for winding up wires attached to an upper portion of the slope surface so as to support the working vehicle main body from the upper portion of the slope surface via the wire fairlead in a hanging manner. The wire upward/downward moving mechanism has the wires located at a location where the wires do not form large traveling resistance when the working vehicle main body travels, whereas it has the wires located at a location where the wires can block rearward toppling of the working vehicle main body when the working vehicle main body assumes a working position.
