Abstract
An auxiliary drive axle assembly is disclosed for a railcar mover that provides traction for a railcar mover when required. The auxiliary drive axle assembly comprises a frame, a plurality of hydraulic motors, and a plurality of wheel assemblies positioned underneath a railcar mover. The auxiliary drive axle assembly may be lowered to a use position where the wheels engage the rails either upon demand by the railcar mover operator or automatically by a control system based upon a set of monitored parameters. When in a use position, the control system directs the power to the hydraulic motors such that the wheel assemblies can have optimal traction to assist the railcar mover.
