PJM developed a mobile calibration test rig for instrumented wheelsets

The advantages:
- After reprofiling the measuring wheel sets, recalibration can be performed on site.
- The new type of test stand enables unprecedented performance.
- The test stand is easy to transport and is therefore ideally suited for worldwide use.

The mobile calibration test stand has already proven its worth during the first "field test" and was used in a project for the Rhaetian Railway. "We can react quickly and flexibly to customer requirements even under challenging conditions," explains Martin Joch, CEO of PJM.
