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.
