XGMA Sanzhong has always attached great importance to enterprise technological innovation and has long carried out industry-university-research cooperation with well-known domestic universities. In recent years, the company has obtained 7 national-level key new products and 38 national patents; 10 new products have passed technical appraisal at or above the provincial level; 6 projects have won provincial science and technology progress awards; and it has undertaken 2 national key technological innovation projects, 1 national Torch Program project, 1 national 863 Program project, and others.

　　The award-winning project, the “XG6131D” tandem vibratory roller, applies multiple patented technologies in its key technologies and adopts the internationally advanced PLUS+1 software to optimize and process various control signals of the machine, effectively improving the smooth transition performance of the machine during starting, vibration start-up, vibration stop, and stopping, narrowing the gap with comparable foreign-brand rollers, and enabling the compacted pavement to have excellent flatness. It can optimally control the vibration operation of the front and rear vibrating drums, reduce the impact of instantaneous peak power on the engine, improve the impact of inertial loads on the hydraulic system, and greatly increase the service life of the engine and hydraulic components as well as the reliability of the machine. At the same time, the overall vibration damping, silencing, and noise reduction effects are remarkable, bringing all noise parameters to the international advanced level. The project is clearly innovative; after being put on the market, it has won customer recognition and praise, and its overall technical level is at the domestic leading level.
