Recently, the SM2000 road milling machine, developed by Sany Heavy Industry, has successfully rolled off the production line at the North No. 3 plant. This cutting-edge product is set to change the landscape of China's large-scale road milling machine market, which has long relied on imported equipment. With its advanced technology and high performance, the SM2000 marks a major breakthrough in domestic road construction machinery.
Road milling machines are essential for modern road maintenance, used to remove damaged layers of asphalt, concrete, and sub-base materials from highways, urban roads, airports, and public squares. They are crucial for addressing issues like potholes, oil bleeding, cracking, and rutting, as well as for performing quick anti-skid treatments. As China’s traffic volume continues to grow, so does the wear and tear on its infrastructure, leading to an increased demand for efficient and reliable road maintenance solutions.
Currently, China's road milling machine industry is still in its early stages, with most large-scale models being imported. However, this gap presents a significant opportunity for domestic manufacturers. In September 2004, Sany officially launched its road milling machine R&D project. After nearly a year of intensive research and design, the SM2000 prototype was completed on schedule, marking a key milestone in the company’s journey toward technological self-reliance.
The SM2000 is a high-performance, large-scale road milling machine that sets new standards in the industry. It was designed based on the blueprint of the world’s most advanced German counterparts, ensuring top-tier quality and functionality. Compared to similar domestic models, it features four unique innovations. First, it uses stepless speed control for walking, offering high efficiency, strong traction, excellent starting performance, and superior braking. Second, it incorporates a dual-handle steering system that allows for flexible and precise control, enabling four different steering modes with just one handle. Third, it includes intelligent cooling fan control, reducing noise and energy consumption. Finally, the movable double console and driver seat enhance operator comfort and ease of use.
In addition, the SM2000 is equipped with a high-performance, custom-designed milling rotor, ensuring both reliability and efficiency during operations. Its overall performance metrics are comparable to those of the world’s leading products, making it a viable alternative to imported machines. The successful launch of the SM2000 not only strengthens Sany’s position in the global construction machinery market but also paves the way for future innovation and development in China’s road construction industry.
