EloRail WPG D340 Inspection Trolley for Rails and Switches

Railway rails and switches are highly stressed components by increasing traffic (load cycles), increasing axle loads and increasing speeds, especially on high-speed lines. Therefore, depending on the load profile, the installed rails must be carefully checked. The mobile ROHMANN WPG D340 inspection trolley is made of ultra-light carbon fiber and can be handled by just one person. Several sensors, each equipped with ceramic wear protection underneath, are guided very precisely along the running edge of the rail by a patented magnetic holder. The system integrates a multi-channel eddy current instrument, an industrial PC for inspections in rough environments and a specific software for data recording, analysis and documentaion.
