A cross-country vehicle which is characterized by the combination of two hydraulically-actuated advancing legs (4, 4') on the front side of the vehicle with two wheels (6, 6') hydraulically adjustable for height and guided by longitudinal swinging arms on the rear side of the vehicle. The forward movement is effected by corresponding movements by means of hand levers and power assistants. An on-board computer automatically ensures a continually approximate horizontal position of the cabin (2) and constantly calculates whether, when a leg is raised, the position of the center of gravity is momentarily located inside the three application points. The decisive characteristic of the invention is that the advantages of advancing legs (4, 4') are combined with those of wheels (6, 6'). The control of the advancing components is considerably simplified by the fact that there are only two. Because the vehicle is of the cross-country type it is particularly suited as a transport vehicle for a variety of forestry implements. |
