KLD Labs - Rail and Wheel Measurement Technology for Track Speed Profile Measurement and Contact Mechanics Studies

KLD Labs, Inc. specializes in the design and development of precision measurement systems for railways, transits and light rails. KLD's core products are the Optical Rail Inspection & ANalysis (ORIAN) system for real-time laser-based rail profile measurement and the WheelScan system for real-time laser-based wheel profile measurement.

KLD conceived the idea of optical measurement for rail and wheel profile inspection back in the mid 1970s. Since that time the products have now become a new standard throughout the world for state-of-the-art measuring of the profile for freight, high-speed, transit and light rail systems.

KLD is the leading manufacturer of these systems and has long-standing relationships with railways, suppliers and contractors in 25 countries. Each system is customized to meet the unique needs of the railway.

KLD's vision is to help railways to easily and efficiently collect rail and wheel profile data at track speeds to allow them to both manage and optimize the rail/wheel interface.

KLD'S RAIL AND WHEEL MEASUREMENT TECHNOLOGY APPLICATIONS

• Wheel and rail profile/wear monitoring
• Wheel and rail profile/wear maintenance
• Wheel and rail profile/wear optimization
• Rail grinding and wheel truing
• Contact mechanics/equivalent conicity
• Quality control

ORIAN (OPTICAL RAIL INSPECTION AND ANALYSIS) SYSTEM

The ORIAN system incorporates the latest laser and video camera technology to provide immediate feedback on the profile and wear condition of the rail whilst 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.

HIGH-SPEED AND HIGH RESOLUTION RAIL MEASUREMENT SYSTEMS

The HSRMS (High Speed Rail Measurement System) is a high-speed laser-based rail profile and gauge measurement system.

The HRRMS (High Resolution Rail Measurement System) is the highest resolution laser based rail profile system KLD offers for both rail wear and profile analysis for conicity studies.

WHEELSCAN SYSTEM FOR WHEEL WEAR CONDITION ASSESSMENT

The WheelScan system provides immediate feedback on the wear condition of all wheels that pass by the wayside measurement system. By incorporating the latest video and laser technology, the WheelScan system takes wheel cross-sectional profile images and performs dimensional measurements on each wheel in real-time.

TRMS (THIRD RAIL MEASUREMENT SYSTEM)

The TRMS is a real-time laser based third (power) rail measurement system. The TRMS measures the position of the third rail with respect to the running rail both vertically and laterally.

HSGMS (HIGH SPEED GAUGE MEASUREMENT SYSTEM)

The HSGMS is a high-speed laser-based gauge measurement system that bases the measurement on the actual rail profile. The system easily integrates with new and existing track geometry systems.
