SYM.SYM was established on November 27, 1979, with its registered location in Shenyang, Liaoning Province. As a leading enterprise in the tower crane industry, the company pioneered the introduction of advanced foreign technology among domestic tower crane manufacturers as early as the 1980s. Designated by the Ministry of Construction as a tower crane producer, it initiated technical cooperation with the internationally renowned French company Potain. Following its restructuring with Shenyang Sanyo Elevator in the early 21st century, the company enhanced its product technology and manufacturing capabilities. Multiple innovations filled technological gaps in China's tower crane sector, while its products have repeatedly earned the National Silver Medal for Quality Products and Ministry-level Quality Product Awards. For 18 consecutive years across six terms, users have recommended SYM as a “Satisfactory Product” and “Satisfactory After-Sales Service Provider.” The company has also been recognized as a Shenyang Famous Brand Product for multiple consecutive years. Products are sold nationwide and exported to 67 countries including Singapore, Malaysia, South Korea, Argentina, and Russia. Key offerings include: tower cranes, construction hoists, crawler cranes, concrete pump trucks, asphalt mixing plants, and building steel structures.
