WheelView—F | I

Wayside Wheel Profile Measurement System

Trimble® WheelView® automatic wayside systems measure the wheel profiles of moving trains. These systems are used to inspect wheels for preventative maintenance, maintenance scheduling, derailment prevention, and to reduce track and rail damage caused by excessively worn wheels.

WheelView-F is a rugged system that operates in harsh environments as well as workshops, depots, and yards. It has an exceptionally robust design capable of operating without human intervention for extended periods. WheelView-F provides wheel diameter measurements at high speeds of up to 85 mph (140 km/h).

  • Wheel diameter based on witness groove

Dramatic time and cost savings, versus manual inspections

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

Rolling stock stays in service for longer

With accurate measurements at line speed there is minimal disruption to rolling stock schedules.

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

WheelView 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 WheelView 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.
