Wheel Profile Measurement

Wheel Wear

KLD Labs offers both automated and portable measurement tools for assessing the wheel profile and wheel wear condition as well as tools for condition based maintenance planning and execution. The wheel profile output is utilized for asset optimization, condition based maintenance, wheel rail interface analysis including equivalent conicity and contact patch studies.


The WheelScan™ system provides immediate feedback on the wheel wear and wheel profile of every axles of each train that passes wayside measurement system. Employing the latest imaging and laser technologies, the WheelScan™ system takes wheel profile images and perform dimensional measurements on each wheel in realtime.  The WheelScan™ system is designed to measure wheel profile, flange height, flange width, qR, flange angle, rim thickness, back-to-back gauge, wheel diameter, as well as other customer specific wheel parameters  in real-time and at track speeds.

This system is designed to be installed in mainline track, marshalling yards as well as in maintenance workshops for the real-time evaluation of these key wheel parameters.  The system also integrates with other track-based measurement and detection systems including wheel impact, brake and bogie (truck) monitoring equipment as well as maintenance management systems. Each wheel image is synchronized with vehicle identification information, transferred to offsite computers to KLD’s web-enabled TrainBase© data management application for fleet analysis and reporting. The system is compatible with enterprise resource planning (ERP) systems such as SAP and  Maximo as well as KLD’s applications for comprehensive vehicle evaluation, trending, predictive maintenance and exception reporting. 


For portable wheel measurement the MiniProf Wheel instrument is an easy to use, lightweight and handheld tool for monitoring cross sectional profiles of the wheel. It is attached magnetically to the backside of the flange. The instrument can be used on many different wheel types ranging from trams to locomotives. The instruments are normally used with a laptop or rugged handheld computer for data collection.  For more information on the MiniProf visit:  http://www.greenwood.dk/miniprofwheel.php
