Accelerating the rise of equipment manufacturing world-class industrial clusters

In July, at the site of Zhegu decentralized wind power project in cuomei County, Tibet, with the crawler crane steadily sending the wind turbine hub to Shanghai for 5150 meters, the "Hunan army of construction machinery" stepped to a "new height".

General secretary Xi Jinping placed ardent expectations on the development of Hunan's advanced manufacturing industry. In September 2020, when general secretary Xi Jinping visited Hunan, he made a grand blueprint for Hunan, and stressed: "the key core technologies must be firmly grasped in their own hands. We should unswervingly strengthen, optimize and expand the manufacturing industry and the real economy. "

The recently issued Implementation Opinions of the CPC Hunan Provincial Committee and the Hunan Provincial People's Government on implementing the opinions of the CPC Central Committee and the State Council on promoting high-quality development in the central region in the new era (hereinafter referred to as the Implementation Opinions) clearly put forward that efforts should be made to cultivate construction machinery, rail transit Changsha Zhuzhou Xiangtan equipment manufacturing world-class industrial cluster focusing on small and medium-sized aeroengines and aerospace equipment, and strive to build an important advanced manufacturing highland in the country.

In recent years, Hunan has vigorously promoted the construction of a strong manufacturing province, focused on cultivating emerging advantageous industrial chains, and the equipment industry has jumped to the trillion level, forming a number of advantageous industrial clusters. Among them, construction machinery and rail transit equipment have become bright business cards made in Hunan and even made in China. Small and medium-sized aeroengines and aerospace equipment have accelerated their march towards world-class industrial clusters. At present, these three industries are mainly concentrated in Chang Zhu Tan area.

The implementation opinions mentioned that "accelerate the intelligent development of construction machinery and improve the competitiveness of large, super large and special construction machinery products". This year, new progress has been made in tackling key problems of digital prototype and twin technology of Shanhe intelligent construction machinery, and the domestic largest diameter earth pressure balance shield machine has been offline in CRCC heavy industry.

"Accelerate the R & D and industrialization of new generation rail transit vehicles, control systems and key components". The core technology of the "Fuxing" EMU, which was first launched on the Qinghai Tibet Plateau, came from Zhuzhou. The first double deck EMU exported to Europe was delivered off the production line of CRRC Zhuzhou Electric Machinery Co., Ltd., and the core power equipment of the 600 km / h maglev train was developed by CRRC Zhuzhou Electric Machinery Co., Ltd.

"Expand the production capacity of small and medium-sized aeroengines and ground gas turbines, and accelerate the industrialization of aircraft takeoff and landing systems and general aircraft manufacturing." The 2021 Hunan (International) general aviation industry expo held in July boosted the industry to "fly" and reached new cooperation and innovation in many fields, such as large aircraft industry, multi-purpose light transport aircraft development, aviation new materials and so on. Relying on the large aircraft ground dynamics test platform established in Changsha, we will spare no effort to build a world-class R & D and industrialization base of aircraft takeoff and landing system.

It is understood that the "14th five year plan" for Hunan Province to build a national important
