Abstract
The on site maintenance system for metal railcar wheels enables the user to establish a portable, stationary guide rail system about a remotely located railcar and then through use of a traversing guide rail system and lathe assembly grind the many wheels of a railcar with minimal time. The traversing guide rail system rollingly traverses upon side guide rails of the stationary guide rail system and is clamped to existing rails in a desired position. Likewise, the lathe system rollingly traverses upon the cross-wise guide rails of the traversing guide rail system. The lathe system then additionally provides three axes movement for fine-tune positioning of the lathe bit to achieve a desired grind profile of the metal railcar wheel. The wheel being ground is driven by a drive powered by the railcar or may be driven by an external drive and motor connected to the exterior hub of the wheel.
