A device for transporting of towed road facilities contains the frame with the wheels mounted on the back of the motor-car, in each of which in the external and internal rims a number of open-end holes are executed, in which the pushers spring-loaded are placed from the side of internal rim. The upper part of each pusher projects out of external wheel rim. Each pusher is hinged with the catch of rocker type and is fastened to the inside of external rim and is located with possibility of leaning by lower end against hexahedral sprocket, which with the sprocket gear is motionlessly mounted on the wheel axle. The drive of wheels includes the chain drive, through which the wheels are connected with the reducer of wheels of motor-car, which through another chain transmission is connected once more with the chain sprocket. Invention allows reducing the tractive force of the car engine.
