Wear measurement system

Brake are designed to wear out. Nevertheless the wear rate has to be monitored in order to maximize the brake life and prevent failures caused by an inefficient interaction with the wheels that can damage them. Wear trends can then be established and used for predictive maintenance. The rail wheel, and in particular the brake and its interaction with the wheel, represent a decisive factor in the sphere of safety and quality of railway transport. The complementary parameter to the brake wear is the brake disk wear which is monitored by a dedicated system. The measurement system acquires the brake disks profile by means of high speed laser-camera triangulation technology determining the actual wear status and distribution. The processing system performs the analysis of the measured parameters and comparison to defined tolerance thresholds. The analysis and reporting software provides performance trending and predictive identification of intervention dates.
