Load-Cycle Tests for Catenary Hangers

10-Hertz-testing machine for fatigue tests

This new fatigue testing device for catenary hangers reaches testing cycles of up to 10 Hertz. It allows unmatched possibilities to test and evaluate wire connections in overhead contact lines. Due to the high frequency it is possible quickly predict the life span of a hanger connection. The device is ideal to analyse hanger connections for high-speed lines.


  • Variable test frequency up to 10Hz
  • Variable force in the specimen
  • Variable compression of the hanger
