Bogie Rotary Parts & Bearings Test Rig

The innovative DTR Dynamic train Bogie Test Rig is intended to be the decisive support tool for assessing the correct railway maintenance of the bogie rotary parts and bearings.

BENEFITS

  • Adaptable to all bogie/wheelset types
  • Cost reduction by extend maintenance intervals and simple maintenance tasks
  • Advanced diagnostics, preventive actions before failures and avoiding accidents
  • Optimized efficiency, increased rolling stock reliability and availability
  • Different parameters can be tested on the DTR:
