SCM is a contactless technology for monitoring the status of rails and wheels. It enables condition-based maintenance and replaces the less accurate time- and mileage-based calculations. SCM offers significant advantages over eddy-current measurement. For instance, no assumptions about crack angles are required. It can also be used to inspect areas where ultrasonic sensing is blinded by surface defects. Where other technologies require highly skilled operators to interpret the readings, SCM needs only minimal operator training and reports an objective, quantitative crack depth, telling you exactly how many millimeters or inches of material to remove from rails or wheels.
The vehicle-mounted system was developed especially for the efficient inspection of longer rail sections. Mounted on a service vehicle, trailer or trolley, the system scans both rails at up to 40 km/h (~25 mph) – perfect for periodic surveys of network health. Additionally, we offer measuring as a service, using MRX owned and operated vehicles, so that you can concentrate completely on your core business.
• Scans both rails simultaneously, for faster data acquisition
• Can be installed on various types of rolling stock
• Available both as a purchase solution and as a service
For medium distances, small maintenance windows or limited track access (e.g. in underground networks) we have developed the walking stick. It is ready to scan in less than a minute and can be removed from the rail within seconds. Rails can be scanned at up to 5 km/h (~3 mph).
• Maximum flexibility
• Maximum track availability for regular traffic
It’s not always about measuring kilometers or miles of rail. When welding, for instance, it’s essential to reliably rule out surface defects near the weld site. Our hand-held unit is designed to inspect very short sections, consistently and reliably. As the lightest, most portable product of its kind available today, this unit gives you greater flexibility – and can be easily converted for use as a wheel measurement device.
• Smallest device on the market
• Light in weight: best portability
• Easy to convert for use on wheels, and vice versa
The hand-held unit allows for an easy, accurate and repeatable measurement of RCF and its depth. It also saves a great deal of time. The handheld device, designed for use in a workshop, simply and efficiently inspects the surface of each wheel. The manual sensor head rolls on the wheel tread to detect and quantify the extent of surface cracking. Unlike the usual visual inspections, the hand-held unit creates a damage map showing the exact position and severity of any damage. This way, rail operators no longer have to rely on rough estimates – they know whether or not a wheel needs to be machined, and how much material needs to be removed.
• Increased availability due to more predictable maintenance
• More precise results than with visual inspection
• Extended wheel lifetime due to optimized machining
• Easy to convert for use on rails, and vice versa
