Technological innovation helps development Changsha builds China's construction machinery capital

The industrial cluster development trend of the construction machinery industry is obvious. Among the fast-developing industrial bases, the Changsha Construction Machinery Base, driven by leading construction machinery companies such as Sany Group, Zoomlion, and Sunward Intelligent, has achieved production capacity output value. In the forefront of the industry, construction machinery has also become Changsha's first 100 billion industry. Strong Ru0026D and technical support capabilities and independent intellectual property rights are the biggest advantages for Changsha's construction machinery industry to lead the country. In the past 3 years, the district has cultivated 61 high-tech enterprises, undertook more than 300 various scientific and technological projects above the municipal level, won 5 second prizes for national scientific and technological progress, and has 1 national engineering research center and 3 national enterprise technology centers. We independently cultivated 4 well-known trademarks in China and 24 well-known provincial trademarks. At the same time, the Park Management Committee, as the only award-winning unit in Hunan Province, has been rated as the 'Advanced Group for the Pilot and Demonstration Work of Intellectual Property Rights in Cities and Parks in China' for two consecutive times. In these projects, construction machinery has made a huge contribution. For example, Sany Group has carried out extensive cooperation with nearly 10 universities and research institutes, such as Tsinghua University and Beijing Institute of Mechanical Industry Automation. The innovation capabilities of enterprises have been significantly enhanced, and a total of 2,661 patents have been applied for. There are 1,441 authorized patents, and the proportion of invention patent applications is 31%. The annual patent application volume is increasing at a rate of 50%. Among them, 'an energy-saving control method for concrete pumps' won the first Chinese patent gold medal for a Changsha enterprise, Sany Heavy Industry Starting from the research and development of the first domestic pump truck, it has continuously created more than a dozen domestic firsts, the domestic first in the production and sales of concrete pumping machinery, and the third in the world; Zoomlion now has 13 major series and 350 varieties of products. It is an enterprise with the richest product categories and the most complete product chain in the domestic construction machinery industry; Sunward Intelligent has industrialized the patented technology of colleges and universities in the park, and it has grown into a modern high-tech enterprise with an output value of more than 3 billion yuan in just 7 years , It has become famous overseas with small excavators and other products with independent intellectual property rights, and the domestic market share of pile workers has reached 40%. A few days ago, Changsha Economic Development Zone launched the 'Thousand Hundred and Ten Project' to focus on building an advanced equipment manufacturing industry cluster of 100 billion yuan, a batch of 10 billion industrial bases and enterprises with revenues of over 1 billion yuan. The key engineering enterprises have formulated special support policies. Under the impetus of construction machinery enterprises, the output value will strive to exceed 100 billion yuan by 2012 and 180 billion yuan by 2015.
