HTM wants to map all (operating) vehicles with automatic wheel measurements. Wheel measurements are needed for both normal maintenance work and an innovative vision on predictive maintenance. The wheel measurement system installed by Althen in the nights can take all measurements automatically on passing vehicles without them stopping and without this having any impact on the timetable. The wear profile and safety values can thus be permanently monitored.
Althen's 3D Wheel+ measuring system for trains and trams
The system consists of RFiD antennas, laser sensors to measure the various wheel parameters and a dynamic weighing/impact system to map the various loads and wheel defects. In short, the Custom Weighing in Motion (AWIM) measurement system measures all aspects of the flange and wheel. Wear characteristics, dimensions, weight aspects (per vehicle, axle and wheel), and wheel defects. Althen also takes care of the backend and the dashboard.
