Automatic Wayside Friction Wedge Inspection System
TruckView is a wayside truck (bogie) and friction wedge inspection system designed to operate on passing trains at normal track speeds. TruckView is a vision based system which uses a high speed imaging system to provide high resolution images of every truck for inspection and measurement. Every truck is viewed from up to two angles for a reliable inspection. For North American freight trucks wedge rise measurement is provided. After the truck type is identified, wedge rise is measured in both sides of the bolster and reported. An average wedge rise is also reported. Depending on the truck type, an alarm is generated for excessive wedge rise. The system also inspects the spring condition, including its compression. This is used to compare the spring compression on two sides of the truck and evaluate the load balance of the truck and the car.
Other inspected components include bearing caps and bolts, side frame condition and mismatch, bearing adapter plate, brake hose, etc.
