Wheel Impact Load Detection

Product Overview


The Wheel Impact Load Detector (WILD) is a widely used system in the world today. WILD detects and alarms on excessive wheel impacts for the targeted removal of defective wheels. An essential component of any performance based wheel management program, the WILD continually monitors rail vehicle wheel health to ensure safe and productive train operations.

The WILD system is a hardened electronic data collection device which measures vertical wheel forces on the rail via rail mounted strain gauges. The Wheel Impact Load Detector measures impact forces caused by damaged wheels. These high impact forces damage vehicles, cargo and infrastructure.
