What is a Profiling Rail Grinding Vehicle?
China's first independently developed FCM-20K Profiling Turnout Grinding Vehicle has officially commenced operation. It adopts a 3D profiling grinding concept, enabling its onboard grinding units to achieve full coverage of the rail profile. This allows for mechanized grinding of turnouts, covering:
✅Straight tracks
✅Curved tracks
✅Transition straight sections
✅Mainline sections extending at least 25m before and after the turnout
The Profiling Rail Grinding Vehicle features adaptive gauge adjustment, delivering excellent positioning adaptability for grinding curves and turnouts. Key advantages include:
✅Rapid grinding response and high control precision
✅Strong operational adaptability with a working speed range of 2-16 km/h
✅High work quality and operational efficiency
✅Integrated dust collection port aligned with spark trajectory, effectively preventing fire hazards
