Wheel profile measurement system

Published: 10 April 2017

The equipment automatically detects passing wheel sets and fires laser-based units to measure the wheel profiles of trains at operational speed.

At the Wheel Profile Measurement Station in Sunderbyn, 20 km north-west of LTU, a wheel profile measurement equipment has been installed in October 2011 by Trafikverket and LKAB. The equipment automatically detects passing wheel sets and fires laser-based units to measure the wheel profiles of trains at operational speed. By combining this information with RFID readings of the wagon identity, the test bed can provide a unique opportunity for eg. wheel maintenance optimization on an individual wheel level. The information generated is collected by the eMaintenance LAB at Luleå Railway Research Center (JVTC).
