Product Overview
Multifunctional track portable grinding machine / Track grinding machine
JG-DGM-2.2 Multifunctional Rail Switch Grinding Machine – Precision-engineered for critical turnout maintenance. This specialized equipment eliminates rail defects in vulnerable switch areas, repairing fat edges, restoring profiles, and correcting wear (≤50mm section width) on switch rails, movable center rails, and wing rails. By eliminating surface irregularities, it enhances rail smoothness while optimizing wheel-rail contact – effectively reducing noise, extending rail service life by up to 40%, and slashing maintenance costs.
Engineered to withstand high-speed/heavy-haul impacts, it combats turnout fatigue failures including spalling, cracks, and poor wheel-rail alignment that accelerate rail degradation. Our innovation delivers three core advantages:
