NGM-4.4Ⅱ Rail Head Profile Grinding Machine

The NGM-4.4II internal combustion rail grinder/rail polisher is designed for grinding burrs around thermit welds and burrs generated due to rail wear. This machine can grind rail heads and rail sides. During operation, the operating frame remains fixed, and the grinding operation of the rail top and rail profile can be completed by simply relying on the gasoline engine and the rack to rotate 90°. During operation, porters will not exert excessive force or bend down, which reduces labor intensity. The machine body is welded with high-quality profiles, light in weight and easy to operate. Can be used for grinding rough steel or precision rail profiles. It is a special device used for rail head grinding operations in railway maintenance // The lithium battery-powered rail bolt wrench (model: LJ-LDB171X) consists of a host machine, a control system, a battery system and a rail traveling part. It has the advantages of compact structure, light weight, flexible assembly and disassembly, easy use, and no exhaust emissions. It can be transported separately, making it easy for a single person to carry it on site. The weight of the separated parts is less than 15kg.
