Hunan Dahan Zhicheng Construction Machinery Co., Ltd. was established in February 2014. It is a large-scale holding company jointly established by Dahan Construction Machinery (Group) and Hunan Kezhibo Machinery Co., Ltd., specializing in the production of tower cranes and construction elevators.

The new registered capital is 60 million yuan. The company is located in the beautiful Dongting Lake Plain-Yuanjiang Economic Development Zone, Yiyang, Hunan. The industrial park covers an area of nearly 60,000 square meters and the production workshop area is more than 20,000 square meters. It produces more than 1,000 medium and large tower cranes annually. It is the strategic production base of Dahan Group in the south, as well as the research and development and supply base of medium and high-end products.

One of the earliest founders of the company, Dr. Yang Chenghui is an expert in the field of tower cranes in the earliest professional research institution (Changsha Construction Machinery Institute) in China. In 2000, he was rated as the "chief researcher" of tower cranes by Zoomlion for the first time. He is one of the creators and pioneers of domestic high-quality tower cranes.

At present, the company's main products are: QTZ63 (5610-6), QTZ80 (TC5613-6), QTZ80 (TC6010-6), QTZ80 (TC6013-6), QTZl00 (TC6513-8), and elevator SC200/200. After the reorganization with Dahan Construction Machinery, the transformation and upgrading of Dahan Group from small and medium-sized tower cranes to medium and large tower cranes was completed.

As the strategic base for the R&D, production, sales and service of Dahan Construction Machinery, Hunan Dahan will successfully implement the national industry brand strategy and internationalization strategy of Dahan Group with a new look and excellent product quality.
