Wayside wheel profile measurement
Trimble® WheelView® automatic wayside systems measure the wheel profiles of moving trains for preventative maintenance, maintenance scheduling, derailment prevention, and to reduce track/rail damage caused by excessively worn wheels.
Accurate inspection and measurement of wheel profile and diameter, at mainline speeds, even in tough environments, day or night
Choose the variant of automatic train inspection and measurement system to suit needs
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).
The other WheelView variants allow for operation in specific conditions and provide a variety of different measurements. WheelView-I is offered for indoors and low speed operations.
Field-proven around the world
In production since 2000, different versions of WheelView including the standard version (WheelView-S) have been successfully deployed in many countries and is currently operational in some of the busiest freight and passenger corridors in the world, measuring over 50,000 wheels every day per system.
Return on investment with cost savings and efficiency improvements
WheelView is an effective system and quickly pays for itself by improving wheel maintenance practices and eliminating derailments due to worn wheels. It increases the efficiency of wheel maintenance by identifying proactive maintenance practices based on the application of wheel wear rates and early wheel defect detection.
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 mainline operational speeds 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.
