Wheelsets
Wheelsets
Our experience is based on a 40 years tradition in equipping all kinds of railway vehicles with wheel sets. KOLOWAG has its own design department responsible for new designs, finite element analyses, noise calculations and laboratory testing of prototypes.
Wheelsets

Wheels
The quality of every wheel we make is supervised during both metallurgical and forging production stages. Steel quality is guaranteed by our Quality Assurance Inspectors, who personally inspect every produced lot of wheel forgings with laboratory tests –both chemical and mechanical.
Machining Processes
  • Mechanical machining of the whole surface of the rough/black wheel
  • Static balance of wheels
  • Magnetic particle test of wheel
  • Fully robotised stand for Ultrasonic test, automatic printout of the results in protocol.
  • Drilling of oil opening
  • Machining of bore for axle
  • Coating with high quality paints according the requirements of the different standard e.g VPI
