The StARK-s is a stationary alternative to the LARS-m mobile wheel contact force measuring unit. This system is extremely flat and compact, allowing structural alterations to be reduced to a minimum and preserving the integrity of built structures.
The modular design and active and inactive sections on the measurement track allow the system to manage a variety of measuring tasks and differences in bogie types and bogie centre distances. The range of a measuring section can be up to 1800mm, duly observing the required accuracy of ±0.5%. The measuring system can therefore also be used in workshops with different model ranges. With this measuring system, the wheel contact force is measured on the running surface of the wheel.
