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.

Automated

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. 

Portable

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

Rail Profile Measurement

Rail Wear Measurement

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

Automated

KLD Labs’ ORIAN (Optical Rail Inspection and ANalysis) family of automated high speed rail measurement systems incorporate the latest laser and imaging technology to provide immediate feedback on the rail profile and rail wear condition while traveling at track speeds. The video cameras capture full cross-sectional rail profiles from the base/web fillet area up to the top-of-rail surface to allow comprehensive and accurate rail measurements.

The ORIAN sensor heads are mounted beneath a railway vehicle. The central computer and peripherals are housed inside the vehicle. As the vehicle travels down the track, a laser system illuminates each rail as a high-resolution video camera records the rail profile for processing and storage on the central computer. The computer then shows exactly how much wear the rail has suffered, as well as the overall condition of the track structure. This information is stored internally and is then transferred off the vehicle to enable data playback and analysis.

The ORIAN™ rail profile measurement systems available capabilities include identifying rail types, measuring rail height, vertical wear, rail width, lateral wear, field/gauge metal flow-lip, rail inclination, track gauge, rail cant (rail inclination) and joint bar/fish plate presence as well as other customer defined measurements.  For reasons of performance, reliability and customer service it has become the preferred rail measurement for the largest rail service providers in the world.

Portable

For portable rail measurement the MiniProf Rail instrument is an easy to use, lightweight and handheld tool for monitoring cross sectional profiles of the rail. It is attached magnetically to the rail and references the adjacent rail for gauge measurement and crosslevel. The instrument can be used on many different rail sections and is easily transported. The instruments are normally used with a laptop or rugged handheld computer for data collection. For more information on the MiniProf: http://www.greenwood.dk/miniprofrail.php

Rail Grinding Assessment

KLD Labs’ System

KLD Labs offers automated machine vision systems in single and dual camera configurations for monitoring the infield rail profile against a rail grinding template to monitor before and after grinding to evaluate the restoration of the rail crown. Over time the rail profile wears due to friction at the rail and wheel interface. The grinding process restores the shape of the rail. In order to facilitate this process KLD Labs’ measurement technology is used throughout the world as critical input to the rail grinding planning and maintenance practices.

KLD Labs’ system incorporates the latest machine vision technology to collect and analyze high resolution images of the rail profile and make direct comparisons to rail grinding templates while traveling at track speeds.   The video cameras capture cross-sectional rail profiles to aid in the planning and evaluation of rail grinding.

The rail profile sensor heads are mounted beneath a railway vehicle and are designed to operate and perform reliably in the extremes of the rail grinding environment.  The central computer and peripherals are housed inside the vehicle.  As the vehicle travels down the track, high-resolution images of the running section are processed and stored on the central computer.  This information is displayed to the operator for immediate feedback as well as stored internally.  The data stored can then be transferred off the vehicle to enable data playback and analysis.

Brake Assessment

KLD Labs offers automated wayside measurement equipment for assessing the wear conditions of brake shoes/pads/discs. In addition, we also offer portable tools for assessing the brake discs.

Automated

The BrakeScan™ system automates the brake inspection process and provides immediate feedback on the brake wear condition of each vehicle, car or wagon that passes wayside measurement system.  By incorporating the latest imaging technology, the BrakeScan™ system acquires high resolution brake profile images and performs dimensional measurements on each brake in real-time.  The system can also be integrated with other wayside detectors including wheel profile, wheel impact and hot wheel detection systems for identifying brake system that may be locked up or malfunctioning.  All BrakeScan™ measurements and vehicle identification information is captured and archived on KLD’s web enabled TrainBase© data management application for detailed analyses, trending and exception reporting.

WITH THE BRAKESCAN SYSTEM, YOU WILL :

  • Detect and Measure Brake Shoes
  • Detect and Measure Hollow Discs
  • Accurately Identify Disc Brake Sets Exceeding Wear Standards
  • Collect Brake Profile Data for Disc Resurfacing or Replacement
  • Database Brake Measurements and Vehicle Historical Information

Portable

For portable brake assessment the MiniProf Brake instrument is an easy to use, lightweight and handheld tool for monitoring cross sectional profiles of the brake disc. It is attached magnetically to the backside of the flange. The instrument can be used on many different brake types ranging from cheek to axles mounted designs. The instruments are normally used with a laptop or rugged handheld computer for data collection. For more information on the MiniProf: http://www.greenwood.dk/miniprofbrake.php
