Abstract: A rigid wheel-lift device, assembled from components, for towing any vehicle or machine having at least two axles and four or more wheels. Particularly a device having parallel beams holding an axle that, when assembled with a tongue, becomes a rigid appendage to the vehicle. Tongue incorporates a hinged arm for raising the vehicle to be towed into position for towing on its trailing axle. A tow truck needs to be equipped only with an adequate hitch fixed to a chassis of adequate capacity.
