Entering the Changde High tech Zone in Hunan, looking at the skyline from afar, a "steel jungle" composed of tower cranes catches your eye. That is the testing ground of Zhonglian Heavy Industry Construction and Hoisting Machinery Co., Ltd. One of the tower cranes with a maximum lifting torque exceeding 20000 tons per meter stands tall, and this "giant" is about to be delivered to China Communications Second Navigation Bureau this month and put into construction of the cross river bridge. After the end of the National People's Congress and the National People's Congress, Changde City began to deploy a three-year action plan to break through the industry through innovation and breakthroughs, and plan for the integrated development of "old industries" and "new tracks". In the Changde High tech Zone, which gathers more than 100 upstream and downstream engineering machinery enterprises, park staff and enterprises such as Zhonglian Jianqi have jointly formulated and promoted the "seize the new track" strategy. On the basis of fully considering the matching advantages with traditional engineering machinery manufacturing, they actively connect with research institutes and related enterprises in the fields of new energy and new materials, and successfully introduce multiple production lines such as hydrogen equipment and aircraft automatic coating, optimizing the industrial structure. Liang Dai, Deputy General Manager of Zhonglian Construction Company, said that the company is currently making great efforts to optimize its product structure, continuously developing high-end innovative products such as large-tonnage tower cranes, and seeking new domestic demand growth points such as wind power, nuclear power, and mega bridges in addition to traditional infrastructure and housing construction. In Changsha, in the digital twin system of the underground engineering equipment of China Railway Construction Heavy Industry Corporation, a shield tunneling machine equipped with various sensors is transmitting data at a speed of 2000 pieces per second, displaying the real-time operation status of the equipment. Operators can remotely interact with each other through hybrid reality glasses, making underground construction "visible, safe, and green". "The Report on the Work of the Government requires strengthening the support of scientific and technological innovation for industrial development. Only by persisting in scientific and technological innovation can we truly realize the transformation and upgrading of the industry to be 'high-end, intelligent, and green'." Liu Feixiang, a deputy to the National People's Congress who led the research and development of this system and chairman of China Railway Construction Heavy Industry, said. Wang Yongsheng, Director of the Digital Twin Research Institute of Railway Construction Heavy Industry, introduced that the current policy tools and market environment support enterprises, universities, laboratories, and other units to jointly form research and development teams, achieving closed-loop innovation throughout the entire lifecycle of research and development, manufacturing, operation and maintenance, and making digital and intelligent achievements more smoothly applied. More policies are gathering strong momentum for the land of Sanxiang, benefiting more related enterprises. In the Changde High tech Zone, intelligent factories of upstream and downstream engineering machinery enterprises such as Teli Hydraulic are under intense construction. Zeng Jun, Director of the Management Committee of Changde High tech Zone, said that the park relies on "knowledge value credit loans"
