The Mitchell Rail Gear for rubber tired excavators is an attachment that is welded to the front and rear outrigger boxes. The guide wheel system is a heavy duty, telescoping tube design.  The guide wheels are spring loaded to compensate for uneven track conditions.

The machine’s rubber tires propel on rail as the rail wheels guide the machine. The guide wheels are cab controlled. The machine can get on or off track anywhere without the need of a rail crossing by simply retracting the guide wheels. With retractable guide wheels there is no need for special trailers. The machine travels on rail under its own power, and can get on and off track to perform various excavating and material handling jobs.

The systems adds 3,150 lbs to the weight of the excavator. 

Options include:

Rail Clamps
