On-Track Wheel Profile Inspection System

The interaction between wheels and rails is one of the key factors on the dynamical behaviour of rolling stock, and consequently, on the safety and comfort of railway vehicles, so it´s necessary to detect with high accuracy and frequency the different parameters of the wheels, and in particular the contact profile.The DWPM, DANOBAT’s latest generation of Wheel Profile Measuring Systems, is the result of years of research and  development work together with competent railway vehicle maintainers and operators.

The system measures the following wheel parameters:

  • Wheel flange height
  • Wheel flange thickness
  • qR factor
  • Back-to-back distance
  • Wheel diameter

BENEFITS

  • Reduced Installations requirements
  • High Accuracy & Repetability of Wheel Parameters Measurement
  • Extreme weather conditions work environment
  • Mechanical Robustness
  • Ease Maintainability & Calibration processes
  • Automatic data collection and analysis
  • Traceability of wheelset data
  • Maximization of wheelset life cycles
  • Minimization of operating costs
  • Wheel parameter evolution and wear rate
  • Recommendation of full or reduced profile for wheel turning
  • Prognosis of wheelset machining and replacement dates
  • Connectivity to other external equipment
