ZTR Axle Gen: Performance for the Future

MINNEAPOLIS, MN and LONDON, ON.  During the lifetime of a locomotive, an axle generator can be replaced time and time again. Debris that chips away at, and eventually shakes the unit loose, can cause unplanned downtime and replacement costs. The ZTR AxleGen not only has a new slim line but it allows for EIGHT individual outputs in one small but robust unit. These outputs feature selectable voltage levels and provide enhanced precision.

“This Interface Module of this device not only provides power for the axle generator itself, but also takes the information the generator is communicating and produces the various speed signals for speedometers, control systems, event recorders or any other devices requiring speed information.”~ Rich Colwell, Rail Sales Director at ZTR Control Systems.

The ZTR AxleGen low profile design reduces the likelihood of damage by debris and its internal design protects it from water and oil that can get inside and freeze. This makes the ZTR AxleGen maintenance free, while increasing the overall reliability of your locomotive.
