Sichuan tower crane participates in the construction of Chengdu's landmark project - Chengdu "Xinhua Star Scientific Research and Production Base Project".

"Xinhua Star" scientific research and production base is a major project in Sichuan Province, located in Sanse Road, Jinjiang District, Chengdu City, based on Chengdu's geographical advantages, positioned in the Jinjiang Industrial Headquarters base cultural creativity, scientific research and design industry development direction, through the gathering of large-scale cultural enterprises and creative enterprises, to create a strong cultural creation Italian industrial base. The main structure of the project is reinforced concrete frame shear wall structure, 4 storeys underground, 42 storeys above ground, 176 meters high, with a total building area of 228,263.63 square meters, of which the ground area is nearly 170,000 square meters.

The C7050 tower crane which participates in the construction of this project is the fist product of Chuanjian Group. Since its appearance in 1996, it has participated in the construction of many major hydropower, thermal power, nuclear power plant projects and large steel structure projects. It has sold hundreds of units at home and abroad, and has a very good response, especially in large-scale hydropower projects in China. It has played a major role in the development of domestic tower cranes from small and medium sized to large tower cranes. In 2000, it was recommended as a high quality product by the French Science and Technology Quality Supervision and Evaluation Committee, and it was listed as a recommended product for China's entry into WTO by the China Council for the Promotion of International Trade. The maximum lifting weight of the lifting tower crane is 20t, the end lifting weight is 5t, the maximum working range is 70m, and the maximum independent lifting height of the walking crane is 79.23m. The tower is a chip structure with convenient assembly and disassembly. This machine has many kinds of types, such as rail walking, fixed, attached and internal climbing.

The mechanism configuration of the machine has been improved continuously in the development of technology over the years. The traditional RCS series mechanism has evolved into the LVF series frequency conversion mechanism. It realizes stepless speed regulation, smooth operation of lifting, rotating, amplitude changing and walking, stable start and brake, good control, complete safety functions and convenient maintenance. The whole machine is simple in structure, the key parts are made of high strength metal structural steel, small in volume and light in weight, and a large number of universal connections are adopted, so the installation and disassembly are convenient and quick.

C7050 tower crane participated in the construction of "Xinhua Star" scientific research and production base project B building project, the tower crane used fixed attachment type of work, the final installation height of more than 220 meters.
