Abstract
An improved tag axle system disclosed which is designed to be accommodated by the tailgate structure of a rear-loading trash compacting refuse truck to provide auxiliary support to prevent overloading of the rear axle of the truck and to better distribute the relative weight carried by all axles of the truck assembly. The system uses a pair of aligned spaced stub axles each having its own separate suspension system and mechanism which operates to raise and lower a wheel assembly. The systems are located on either side of the tailgate assembly and are preferably built as an integral part of it. The axles are further configured so as to be raised or lowered with the use of pneumatic springs.
