Grind weld and/or weld repair. 2.1. Rail is ground to profile using approved equipment in accordance with workplace procedures. 2.2. Grinding equipment is operated safely in accordance with work health and safety (WHS)/occupational health and safety (OHS) and environmental requirements. 2.3.Vossloh Rail Services' utilizes passively driven grinding stones on its High Speed Grinder, which adapt automatically to the rail's profile. In the new HSG-2 generation, the grinding units can be individually adjusted to dedicated areas of the rail head to actively influence the rail profile.
The LORAM grinding vehicles will be soon in service in Germany and thanks to their rail diagnostic capabilities will be able to verify, in real time, the efficiency of the grinding itself. Rail Profile and Rail Corrugation Systems provided to LORAM have been subject to a severe assessment process by the final customer DB which has validated the ...For the Wuhan–Guangzhou railway line, normally the grinding interval for the tangent track and large-radius curve is 2–3 years, and for the entering and exiting tunnel sections, the grinding interval should be set for 1–2 years, which could remove the damaged layer of the rail surface and could restore the designed profile of the rail and ...
HBW due to wheel/rail interaction of cold forging. In addition, since rolling stock wheels are associated with lower speed and low axle weight, the actual wheels do a smooth grinding on softer steel rails, effectively helping to self-maintain embedded tracks. This is by far the best method to avoid any Rail Contact Fatigue (RCF) or headCNC Profile Grinding Machine For Grinding Rail & Carriage.
