"Sany Heavy Industry produced 86 meters of ultra-long steel boom pump truck, the use of ultra-strong steel completely by China's independent research and development, strength as high as 1800 MPa." In the 31 exhibition in Changsha, Hunan, Liang Linhe, a director of the 31 group, told visitors that the pump has created the longest arm frame, the largest number of arm racks, and the fastest pumping speed of the fastest three world.
It is only one of the "transcripts" of Changsha construction machinery. Changsha is the region with the largest number of products and the largest number of well-known enterprises in the global construction machinery industry. The mechanical output of concrete accounts for 80% of the global output, and the large diameter full section hard rock tunnel boring machine accounts for 67% of the global market share, and the output of lifting machinery and excavator is the first in China. 4 of the top 50 construction machinery companies in the world are rising in Changsha. Changsha, the top 5 of China's construction machinery, accounts for 3 of the total.
At present, Changsha is making great efforts to build the construction machinery industry into a world-class advanced manufacturing cluster, to the high-end of the global value chain.
Located in Changsha, Sany's "No. 18 factory" is Asia's largest intelligent manufacturing workshop. Through the research and development of industrial Internet related technology and large-scale application, the workshop production line will be able to downline a product in a few minutes. The per capita efficiency has increased by 400% and the per capita output value is increased by 24%.
Liang Linhe said that the technology of digital chemical plant has been applied in 31 and more than 10 business units, and it is good to deal with the pressure and challenge of many varieties, high efficiency, high quality and low cost of the construction machinery enterprises.
The design of large diameter full face hard rock tunnel boring machine involves many patents, and the related technology has been monopolized by the West for a long time. But within a few years, China Railway Construction Heavy Industry Group Co., Ltd. has realized the independent manufacture of large diameter full-section hard rock tunnel boring machine.
"At present, the domestic market share of this machine is more than 85%." Ma Chengbiao, Minister of the propaganda brand of iron construction heavy industry, said.
"Changsha construction machinery industry cluster has obvious advantages and strong ability of independent innovation." Huang Tao, Secretary of the Committee of the Committee of Changsha economic and Information Committee, and director of the Committee of the Committee of the Committee of the Committee on economic and information technology of Changsha, believe that the high quality enterprises such as Sany, ZOOMLION, iron construction heavy industry, mountain and river intelligence, and many research institutions and scientific research institutes of engineering machinery specialization are the cornerstone and push of the development of Changsha engineering machinery industry.
In the face of the relative backwardness of the supporting enterprises and the "short board" of the industrial chain, Changsha is also "heavy punching". The "industry chain service guarantee mechanism", "industry chain service guarantee mechanism", "precision investment mechanism of industrial chain", is set up, and according to the development orientation of each industrial chain, it leads business, inviting people and introducing capital in the global scope.
It is estimated that by 2020, the output value of construction machinery industry in Changsha is expected to reach 200 billion yuan. Wen Shuxun, chairman of the Changsha Municipal Political Consultative Conference (CPPCC) and the chain length of the industrial chain of engineering machinery, said that the Changsha engineering machinery industry not only needs "all the stars to win the moon", and is a strong leading enterprise; it also needs to be "all over the world" to improve the local matching rate of the construction machinery, the strong chain chain extension chain of the chain and the chain, the large pattern of the growth of the sand industry chain.
