TW7 CMS is a mobile corner force measuring system for the quality assurance of rolling stock, which measures vehicle bodies according to the four points method on a straightening stand. It records the four points forces and height tolerance, calculates the nominal forces via the position of the vehicle’s center of gravity, in order to provide the torsion free position of rail vehicles by adjusting the thickness of the shims, and permanently maintain the vehicle on the torsion free position.

TW7 CMS is very flexible and high-precision, which can be used in the rail car manufacturing shop, final assembly, retrofitting, repairs and the condition analysis of accident vehicles. An operating software is available for process control, evaluation and archiving, which help to adjust the torsion free position automatically. All relevant data and measurement results are stored in a database.


  • Designed for production, maintenance and repair of rail vehicles without bogie.
  • Check corner force measurement, center of gravity in torsion free position.
