Railcar Movers

Based on the MP 96 Series, Portable Radio Remote Control (PRRC) provides the safety, function and performance you expect for all railcar moving operations. PRRC offers safe and efficient control of switching, coupling and disconnection and ensures complete control regardless of any coupling arrangement.

It takes only one operator on the ground to effectively control any switching operation with the PRRC. The system provides the all-important extra margin of safety by enabling the operator to input all commands out of harm's way while having greater visibility along the length of the train.

The MP 96 Railcar Mover system is especially beneficial for positioning of railcar wheels for machining. The wheels must be positioned exactly during the trueing procedure. PRRC enables the wheels to be contoured while they remain on the railcars and are machined to tolerances.

MP 96 controllers are designed for instantaneous system troubleshooting. Should an emergency stop be required, the MP 96 responds immediately. With its powerful multi processor system, the MP 96 provides high message data security along with simultaneous and independent data signal processing of all incoming commands.
