The DWL-48 Continuous Action Tamping and Stabilizing Machine can both achieve the continuous three-crosstie tamping operation and stabilize the power of railway. In contrast with the two-crosstie continuous tamping machine, it enhances the working efficiency by approximately 30% ~ 40% and accordingly becomes the railway tamping machine which possesses both the highest working precision and efficiency and the most advanced performance nowadays all over the world. By virtue of the additional compound controlling track stabilizer, the tamped railway directly obtains a quite high precision and sufficient stable performance, and this allows the high-speed and full-load operation of railway after the railway is opened.

Adopting the technology of circumferential milling and equipped with the computer monitoring system, the rail milling and grinding machine effectively helps perform copy milling and grinding of the rail and allows reaching the desired effect at one time work. Extending the rail life after completely eliminating rail defects and failures; improving rail longitudinal regularity and cross-sectional profile quality (reducing rail wear, improving wheel-rail contact geometric state, lowering relative wheel-rail wear); saving rail maintenance and re-use costs; decreasing the working noise; optimizing the operational safety and efficiency of the railway network. It is featured by higher working precision, favorable effect, fewer limits, shorter setup-time, smaller environmental influence, and lower working costs.
