Abstract
A wheel lift vehicle lifting and towing device includes a boom mounted to a towing vehicle and having a cross bar connected to its rear end. A wheel retainer assembly mounted to each end of the cross bar includes a wheel grid having a transversely adjustable wheel chock. A wheel retainer arm is horizontally rotatably mounted above an outer end of the wheel grid and has a wheel retainer member mounted at its outer end which cooperates with the wheel chock to retain a wheel.
Claims11
A wheel lift vehicle lifting and towing device for attachment to a towing vehicle comprising:
- a boom for mounting to a towing vehicle;
- a cross bar connected to a rear end of said boom;
- a wheel retainer assembly mounted adjacent each end of said cross bar;
- each said wheel retainer assembly comprising:
- a wheel grid mounted on an end of said cross bar and including a wheel chock transversely adjustable with respect to said wheel grid;
- a wheel retainer arm rotatably mounted adjacent a first end thereof to an outer end of said wheel grid and positioned above said wheel grid, said wheel retainer arm being non removable and having a length which is fixed with respect to said wheel grid, said wheel retainer arm being horizontally rotatable from a position outside a vehicle wheel to a wheel retaining position adjacent the outside of the vehicle wheel;
- and
- a wheel retaining member mounted transversely to and adjacent a second end of said wheel retainer arm and cooperating with said wheel chock to retain a wheel therebetween.
