Railway Wheel Testing System | MT testing facility

 

HELLING  railway wheel testing system  for detection of

  • surface defects and
  • near-surface defects of any orientation direction at railway wheels

by magnetic particle testing.

This facility is suitable for

  • testing of assembled wheelsets
  • testing during production of rolling stock wheels
  • reconditioning of rolling stock wheels

This  railway wheel testing system  consists of a special stabil metal rack with lifting device. Contactless magnetisation of the complete surface (except the inside diameter of the wheel hub) is possible by specially developed trapezoidal coil for wheels of 700 mm - 1,200 mm diameter.

Testing is performed by fluorescent water-based magnetic particle Suspension under UV irradiation. For this purpose the trapezoidal coil is equipped with an integrated magnetic particle suspension rinsing system.  The magnetic particle suspension is elevated from a 40 L tank by the integrated pump with mixing system.
