Abstract: A towing device, adapted to be mounted to a chassis of a vehicle, features a bi-planar rotation mechanism which allows a telescoping beam to dynamically pivot about two orthogonal axes. The towing device includes a sub-frame mounted to the chassis. An underframe is pivotally attached to the sub-frame to move between a retracted position, adjacent to the sub-frame, and an extended position, distal from the sub-frame. The telescoping beam extends from the underframe and terminates in a carriage, which is adapted to support the wheels of a towed vehicle. In this fashion, the telescoping beam allows the towed vehicle to dynamically pivot about two orthogonal axes which avoids "high centering" of the towing vehicle.

Abstract: A compact tag axle assembly which may be retrofitted to an existing vehicle such as a tilting bed carrier to allow the vehicle to comply with axle load regulations when operated over public roadways. The assembly mounts behind the vehicle's rear axle such that the auxiliary wheels are in close proximity to the rear vehicle wheels, with the support framework of the auxiliary wheels entirely behind the mounting location of these wheels. The assembly consists of two interconnected independently suspended auxiliary wheels which are connected to the vehicle through a centrally located pair of common mounting brackets. The assembly has a minimal longitudinal displacement relative to the main vehicle rear wheels and is easily mounted beneath an existing vehicle.
