Trimble WheelView System

Wheel profile measurement

Trimble® WheelView® is an automatic wheel profile measurement system that generates wheel profile and measurement data for each wheel of a moving train at mainline operational speeds.

Trimble WheelView utilizes high-speed, high-quality digital imaging and laser illumination to automatically reconstruct the wheel profile in three dimensions and to report wheel wear measurements and defects from wheel profile data.

The data that WheelView generates enables rolling stock operators to improve and optimize their maintenance processes. Worn wheels can be identified and maintained earlier, reducing costly incidents. Data driven predictive maintenance practices can be used to maximize wheel lifecycles. Historical wheel profile and measurement data can also be utilized for wheel and rail interface analysis.

Key Features

  • Sophisticated image processing algorithms to assess condition and report detected defects.
  • Processed data and measurements are integrated into the Trimble CMMS™ (Condition Monitoring Management System) software to provide web-based access for data visualization, alarm management, and data analytics.
  • Works in the toughest rail environments and extreme weather conditions at mainline operational speeds.
  • System installation does not require any major track modifications.


Trimble WheelView system measurements include:

  • Full wheel profile.
  • Flange height.
  • Flange width (thickness).
  • Flange slope.
  • Tread hollow.
  • Rim thickness.
  • Back-to-back (B2B).
  • Tracking position (wheel lateral position).
  • Wheel diameter.
  • Wheel width.
  • Tread rollover.
  • Flange rollover (arris).
  • Equivalent conicity (additional module).
  • Depth to witness groove position (if any).
