Abstract
A wheel lift type vehicle lifting and towing device which includes an extendible and tiltable boom having three telescoping sections for extension from the rear of a towing vehicle and means for raising and lowering the boom. The boom is extended and retracted by a pair of hydraulic cylinders mounted within the first and second boom sections. Another pair of hydraulic cylinders are pivotally mounted to the towing vehicle within the understructure thereof and the boom to tilt the boom. The means for raising and lowering, for extending and retracting and for tilting the boom all may be operated independently of each other. When the apparatus is in a storage position, it is retracted substantially out of view within the understructure of the body of the towing vehicle.
