Originally founded in 2005, Dongguan Yixin Qingjiang Machinery Manufacturing Co., Ltd., also known as AISUN, is a professional firm committed to the design, research & development, manufacturing, sales, and thorough technical training of construction equipment including tower cranes and construction hoists.
Our main products include Luffing jib tower cranes, Flat-top tower cranes, Construction hoists, and Industrial Elevators.
Essential for vertical transportation and lifting large loads at building sites, these tools help to transfer both materials and individuals over different heights—a vital need in building projects. Our tower cranes come in more than 30 versions with lifting capacities ranging from 3 tons to 20 tons and jib lengths ranging from 24 to 75 meters. Likewise, our construction lifts cover more than 30 models with weight capacities ranging from 1 ton to 4 tons and lifting speeds ranging from 34m/min to 96m/min, therefore addressing a broad range of uses.
Currently housed in a facility of more than 80,000 square meters devoted to research, manufacturing, and offices, our company boasts cutting-edge modern processing capability. We have made investments in huge gantry boring and milling machines as well as fully automatic laser cutting machines to greatly improve cutting precision, thereby guaranteeing product quality. We also further treat welded components to satisfy strict quality criteria and reach more accuracy.
Understanding the particular geographical difficulties in coastal and Hainan regions, we have designed our equipment to have great wind resistance during non-operation. Every piece of our equipment follows strict design guidelines and is constructed of high-strength steel. Against several big typhoons, our tower cranes have shown their robustness:

Since 2012, AISUN tower crane products' sales volume has surged to the first place among manufacturing peers in Guangdong Province, China. Apart from sales in China, AISUN exports its products and services to countries such as Brazil, Indonesia, Malaysia, and Nigeria.

Before starting AISUN Company, Chairman Chen Yichuan was a construction contractor. Two of the four primary tie rods of a tower crane in use totally broke in 2003 during a building project, creating serious safety concerns and immediate risk of collapse. The project was instantly stopped to guarantee the safety of staff and tools. The crane manufacturer took over half a month to replace the tower crane, therefore costing the project major financial damages.
After this episode, Chairman Chen Yichuan focused especially on the safety performance of building tools. Having worked in the building sector for years, he came to see that at the time construction equipment's quality and service could not keep up with the growing expectations of the market. Driven to change things, he made the investment in starting a professional business emphasizing customer service and safety.
In 2005, with investment from Dongguan Yixin Industry and Trade Development Co., Ltd., and technical and personnel support from China North Industries Group Corporation (CNIGC), Dongguan Yixin Qingjiang Machinery Manufacturing Co., Ltd., known as AISUN, was formed. The company started off committed to delivering reasonably priced, premium tower cranes, construction hoists, and other equipment. AISUN's goal was very clear: provide customers with outstanding, all-encompassing services guaranteeing dependability and safety on every product.
Chairman Chen's vision elevated AISUN to become a top supplier in the sector, therefore establishing new benchmarks for construction equipment quality and service.
In 2005, jointly established the company in partnership with Chongqing Dajiang Group.
In 2007, Dongguan Yixin (AISUN) Company started independent operations.
In 2017, AISUN obtained ISO9001 Quality Management System Certification.
In 2018, AISUN participated in bauma CHINA (Shanghai International Trade Fair for Construction Machinery).
In 2019, AISUN provided venue and tower cranes for the Guangdong Province Crane Industry Vocational Skills Competition.
In the same year, also participated in the Cambodia International Construction and Engineering Machinery Exhibition (CAMBUILD 2019) in September and October, and the Hanoi International Engineering Machinery and Industry Exhibition in Vietnam.
In 2020, AISUN’s tower cranes and construction hoists were presented in the Shanghai Bauma Exhibition.
In 2023, AISUN’s new office building was completed.
