FIELD: transport engineering; wheeled vehicles with one or several drive wheels. SUBSTANCE: wheeled vehicle has number of support wheels which can be lifted. When vehicle is coupled with load, support wheels can be lifted over the ground, thus forming easily steerable system. Owing to correct selection of point of gravity center, pressure of drive wheels will be relatively low. As support wheels can be lifted independently, coupling of vehicle is facilitated. EFFECT: enlarged operating capabilities. 8 cl, 5 dwg
