  • Rail Grinding Practices in North America

    Preventive rail grinding typically requires rail grinding cycles of 25–35 million gross tons (MGT) in sharper curves and 50–70 MGT in tangents or shallow curves. At each grinding cycle about 0.004 inch is removed from the rail center and 0.007–0.010 inch of metal is removed from the rail gage and field corners in a single pass.5 2.

  • High Speed Grinding new projects and options

    New grinding machine HSG-metro for the Chinese light rail market The Chinese light rail market is likewise highly interested in preventive rail maintenance. For more than a year now the HSG-city has been in regular use in several cities where it is effectively remedying rail defects and helping to Due to the extensive use of the crane the running surface of the crane rails had worn. To refurbish the running surface and obtain parallelism again we grinded the running surface over the full length of 160 meters. For this we had to design and assemble the grinding machine from scratch and ship it to Singapore in a very short time frame.
