at the national science and technology award conference held recently, Zoomlion's "key technology and application of super large tower crane" won the second prize of the national science and technology progress award. The project has broken through a number of technical bottlenecks of super large tower cranes, formed a complete set of technologies with independent intellectual property rights, and broken the monopoly of foreign similar products. At the same time, it is also the highest scientific research honor in China's construction machinery industry so far

"the project of" key technology and application of super large tower crane "has created a direct economic benefit of 1.023 billion yuan in recent three years, obtained 16 invention patents, and directly affected the revision of 4 national standards." Yulekang, deputy general manager of Zoomlion construction hoisting machinery Co., Ltd., said to that, as a world-class construction machinery enterprise that adheres to the comprehensive development driven by scientific and technological innovation, Zoomlion delivered a perfect answer to the scientific and technological innovation in 2013

Zoomlion has been leading the world in the R & D and innovation of tower crane technology. As early as the 1950s, the Construction Machinery Research Institute, the predecessor of Zoomlion, laid the foundation of China's tower crane technology. After the establishment of Zoomlion, its tower crane technology R & D team has made remarkable achievements, and the award-winning "key technology and application of super large tower crane" project is the concentrated achievement of the R & D team in the field of tower crane technology for decades. In recent years, large-scale modular construction technology characterized by "resource saving and environment-friendly" has increasingly become the preferred mode for large-scale engineering construction. Large scale modular construction usually requires the support of lifting equipment with large lifting capacity, large lifting torque, large working range, large lifting height and high reliability. As the only lifting equipment that can take into account these performance indicators at the same time, super large tower crane has become an indispensable key equipment for large-scale modular construction

under the opportunity of transformation and development of construction technology, Zoomlion established a project team of "key technologies and applications of super large tower cranes" aimed at breaking through the cutting-edge technology of tower crane products in 2004 to develop and improve green and efficient construction related technologies for the purpose of ensuring "safety", improving "super large lifting capacity" and improving "accurate positioning capacity". In the past 10 years' research, the project team has successively overcome three difficult topics, namely, the design and control technology of super long and heavy-duty boom, the design and control technology of heavy-duty and super large rope capacity winch system, and the safety operation technology of super large tower crane. The 13 products developed with these three technologies as the core have repeatedly set new records in the construction field

relying on the advanced technology developed by the "key technology and application of super large tower crane" project, Zoomlion independently developed D tower crane, which shows the cutting-edge achievements of the research project, In addition, it has created many "firsts" in the history of bridge construction in China in the Ma'anshan Yangtze River Highway Bridge project, the three tower and two span suspension bridge with the largest main span in the world. For the first time, the lifting equipment has lifted objects of more than 200 tons to a height of more than 200 meters at one time. The bridge steel and low-cost modified tower structure can be installed with 42 segments in 90 days for the first time. In the construction of Wuhan yingwuzhou Yangtze River Bridge, due to the super lifting capacity of d5200, the design scheme of the bridge was improved, directly saving the project investment of up to 720million yuan

according to Yu Lekang, the "key technology and application of super large tower crane" project has created a direct economic benefit of 1.023 billion yuan in the past three years, obtained 16 invention patents, 37 utility models, and directly affected the revision of 4 national standards. The project's scientific researchers have published 7 papers, and the series of products have been identified as "international leading level" by peer experts for many times. At the same time, in view of Zoomlion's outstanding achievements in the field of tower cranes and other cranes, in August 2012, the Secretariat of the international organization for Standardization - Crane Technical Committee was moved from Britain to China and settled in Zoomlion, which is also the only international standardization Secretariat in China's construction machinery manufacturing industry

Yu Lekang said that the national science and technology progress award is the best reward for Zoomlion's years of commitment to industrial science and technology research and development and independent product innovation
