AISUN Cranes are renowned at home and abroad for their safe and reliable product quality and premium, high-end service. All equipment is manufactured using high-grade steel, with structural designs that consistently exceed both national standards and industry benchmarks. Special consideration is given to the unique geographical conditions of coastal regions and Hainan, effectively enhancing the cranes’ wind resistance when idle. As a result, AISUN-brand tower cranes have withstood numerous super-strong typhoons and continued to perform reliably under a wide range of complex operating conditions.

Since 2012, tower crane sales have risen to the top position among manufacturing peers in Guangdong Province. In addition to domestic sales in China, AISUN’s products are also exported to overseas markets, including Brazil in South America, Indonesia and Malaysia in Southeast Asia, and Nigeria in Africa.
