Multi-function rail portable grinding machine

Product Details

The DGM-2.2 multifunctional turnout grinder is suitable for eliminating or repairing rail damage in weak parts of the railway.

turn out. Mainly repairs problems such as fat edges, irregular shapes, and impairment of point rails, movable center rails, and wing rails.

The cross-section width is below 50 mm to slow down the development of rail surface defects, improve rail surface finish, and further improve wheel-rail contact relationship and passenger comfort. The purpose is to reduce wheel-rail noise, extend rail service life and reduce maintenance costs.

Under the impact of high-speed and heavy-duty trains, switch and frog rails often suffer from defects such as falling blocks, fatigue cracks, fat edges, and poor wheel-rail relations due to contact fatigue, resulting in reduced rail life, maintenance workload, and maintenance costs. The cost increases and even seriously affects driving safety.

The purpose of research and development of this project is: first, to increase labor intensity, mainly used for repair

If the turnout rail surface is damaged, this machine has high efficiency, light weight, and is safe, convenient and reliable on and off the road surface; secondly, it saves manpower and reduces maintenance costs; thirdly, it is necessary to focus on improving the grinding accuracy of the turnout rail and repairing the rail profile at the turnout point (center). Solve the uneven stress relationship between wheel and rail and extend the service life of switch rails.
