Sany specializes in high-prototype rollers to win the roof of the world

In the construction of the Qinghai-Tibet line at an altitude of more than 5,000 meters, the problem of hypoxia on the plateau greatly troubled the operation of the engine of the construction equipment. Sany R&D personnel overcame all difficulties and took the lead in developing high-prototype large-tonnage rollers, graders and bulldozers. With its excellent plateau operation performance, Sany roller beats imported and other domestic brands, challenges the limit of life, and raises the "roof of the world".
