Trimble® AOAView is a wayside angle-of-attack (AOA) measurement system that integrates with AEI for vehicle identification and reporting.
AOAView is designed to measure AOA of both wheels of a wheel set simultaneously. Since AOAView is installed on a tie (sleeper) between the rails, it provides a reliable AOA measurement as track fluctuations due to dynamic loads do not affect where the measurements are performed. Also, AOAView provides extremely accurate measurements of back- to-back distance of wheel sets with multiple measurements from both wheels of an axle.Datasheet
Automate and complete optical wheel surface inspections quicker, minimizing time taken, costs, and issues that disrupt service.
With accurate measurements at mainline operational speeds there is minimal disruption to rolling stock schedules.
TreadView works in even the toughest environments and at night so field workers are not in unpleasant or unsafe working conditions thereby reducing the risk to their safety.
Providing digital records that are usable across operations and maintenance TreadView reduces manual and paper-based workflows saving time and money. Critical issues are flagged and reported automatically so that corrective actions can be taken with less impact on service.
