YD-22 type hydraulic tamping machine adopts double column, single cylinder lifting mode, the line that has certain density of ballast tamping and elasticity, improve the overall stability of the track and ride comfort, can not only prolong the service life of the rail, also can prolong the service life of the wheel, the train runs more smoothly, reduce the railway transportation cost.

YD-22 type hydraulic tamping machine applicable scope and characteristics

YD-22 type hydraulic tamping machine is mainly in order to meet the need of heavy rail structure and heavy haul, high-speed passenger transport of high density and design. The application of mechanical line tamping, can completely replace the traditional line maintenance equipment, to overcome the traditional line maintenance tools high labor intensity, low working efficiency, poor quality of tamping. YD-22 hydraulic tamping machine for tamping device has many advantages of light weight, flexible operation, low failure rate, good quality, tamping Road convenience etc..
