Like New (284 Hrs since installed new in 1998) American Underfloor Wheel Truing Machine is an underfloor pit-mounted milling machine, capable of simultaneously re-profiling both wheels of a railway wheel set using the axle centers as the machining reference point. It is capable of profiling wheel sets to necessary specifications for tape size, concentrically and plane dimensions in any of the following situations: Machine includes 6 Milling Heads –
1- While the wheel set is under a locomotive, passenger or freight car, transit vehicle, or other rolling stock.
2- While the wheel sets are mounted in a truck.
3- While the wheel set is demount-ed as a single set.
The Machine will re-profile both wheels simultaneously to equal diameters, leaving a witness groove at the flange of the profile.
Both wheels of a wheel set will be finished automatically to the diameter that is required to clean up, while removing the minimum amount of metal possible.
