PROBLEM TO BE SOLVED: To overcome the problem wherein the vital cause inhibiting mechanization of in-forest work is that the job site is slope lands in most cases in different environment.SOLUTION: A steep slope ascending-descending traveling vehicle has the center of gravity in the vicinity of a frame central part for driving an advance-retreat by its frictional force while rolling a wire rope inside, by rotating a wheel having no rotational relationship with the wheel by two wire ropes fixed in parallel to the vicinity of the advance final point, while horizontally holding the front, rear, left and right of a frame upper surface, by vertically moving by a distance between a reference distance with the ground surface from the frame center and a grounding surface of the respective wheels by separately controlling a wheel bearing arm, using various sensors and PCs. |
