Trimble TreadView System

Wheel surface inspection


Trimble® TreadView® is an automatic non-contact optical inspection system that images and inspects wheel surface at mainline operational speeds.

Trimble TreadView system employs state of the art digital high speed imaging and 3D laser scanning technology to automatically inspect the wheel tread, flange, and plate surface areas across the entire circumference of the wheel.

Trimble TreadView automates wheel surface inspections, reducing out of service time, costs, and manual inspection labor. The system can improve efficiency in maintenance processes through the early detection of defects and data driven optimization of wheelset lifecycles.

Key Features

  • Sophisticated image processing algorithms to assess condition and report detected defects.
  • Processed data and images 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 or extended closures.

Inspections & Measurements

Trimble TreadView system inspections and measurements include:

  • Shelled and spalled tread.
  • Major scrapes, dents, and gouges.
  • Broken/missing wheel sections.
  • Shattered rim.
  • Broken or damaged flange.
  • Wheel flats and slid flats.
  • Wheel OOR (out-of-round).
  • Built-up tread.
  • Tread groove.
  • Vertical split rim (flange or field side).
  • Significant spread rim.
  • Wheel tread hollow around the wheel.
