  • Patent number: 5692871
    Abstract: A wheel lift towing device includes a boom for mounting to a towing vehicle and having a cross bar connected to its rear end. A pair of wheel retainer arms are each rotatably mounted offset from one end of the cross bar and devices are provided for rotating each wheel retainer arm which includes motive devices operatively connected to the wheel retainer arm by elongated flexible devices. Each wheel retainer arm cooperates with a wheel retaining plate and an end of the cross bar to cradle and support a wheel.

  • Patent number: 5061147
    Abstract: A combination tilting bed carrier and attached wheel lift for mounting on a chassis of a towing vehicle wherein the bed carrier is pivotably connected to the chassis and first motive devices extend between the chassis and the bed carrier for tilting the bed carrier. The wheel lift is positioned below the bed carrier and pivotably connected thereto. Second motive devices extend between the wheel lift and the bed carrier for independently tilting the wheel lift relative to the bed carrier and the chassis.

  • Patent number: 4929142
    Abstract: A subframe structure for a tilting bed vehicle carrier. The subframe structure has an attached wheel lift and the subframe is pivotally mounted on the chassis of a towing vehicle. The subframe structure includes pivotally mounted strut members for load distribution within the subframe. The load which is distributed by the strut members tends to counteract the bending and torsion forces imposed upon the subframe structure by the towed vehicle on the rear wheel lift.

  • Patent number: 4927315
    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.

  • Patent number: 4875822
    Abstract: Oppositely extending telescopic wheel support sleeves with wheel support cradles are attached to open top shoes provided at the outer ends of the sleeves. Each of the cradles has a connector arm for securing the cradles to the shoes so that the sleeves and the cradles cooperate to support the wheels of a towed vehicle. The open top shoes provided at the outer end of each of the sleeves allow the end of the connector arm nearest to the shoe to enter the shoe by swinging downwardly in an arc extending from a position above the shoe into the shoe. The connector arms are locked in the shoe.
