SYM.SYM was established in 1979 and is headquartered in Shenyang, Liaoning Province. It stands as a leading enterprise in China's tower crane industry. As early as the 1980s, the company was designated by the Ministry of Construction to engage in technical cooperation with France's Potain, pioneering the introduction of advanced foreign technology into China's tower crane sector. Following its restructuring with Shenyang Sanyo Elevator in the early 21st century, SYM significantly enhanced its technical and manufacturing capabilities. Multiple innovations filled domestic technological gaps, with products repeatedly honored with the National Silver Medal Award and Ministry-level Product Excellence Awards. For consecutive years, customers have rated SYM products as “Highly Satisfactory.” Its offerings not only dominate the domestic market but also export to 67 countries worldwide, including Singapore, Malaysia, and Russia. Its main products encompass tower cranes, construction hoists, crawler cranes, concrete pump trucks, asphalt mixing plants, and building steel structures.
