AOAView

Wayside Angle of Attack & B2B Measurement System

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
  • Measure AOA on both wheels of an axle
  • Measure B2B in two sections of the wheel
  • Axle lateral position
  • Identify warped trucks
  • Detect hunting railcars (if three units are installed)
  • Wheel plate type recognition (if applicable)

Dramatic time and cost savings, versus manual inspections

Automate and complete optical wheel surface inspections quicker, minimizing time taken, costs, and issues that disrupt service.

Rolling stock stays in service for longer

With accurate measurements at mainline operational speeds there is minimal disruption to rolling stock schedules.

Limits risk to personnel, works 24/7, even in tough environments

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.

Digital accurate records, with automated alerts of issues

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.
