China Construction machinery information

Guide: in January 2011, Dai Qinghua, general manager of Sany Heavy Machinery Co., Ltd., won the title of the outstanding contributor to the first national low carbon economy. The first selection of outstanding contributors to the national low-carbon economy was jointly carried out by the China Association for social, economic and cultural exchanges and the China Industry News Association. The award revolves around the national energy conservation

in January 2011, Dai Qinghua, general manager of Sany Heavy Machinery Co., Ltd., won the title of the first "outstanding contributor to the national low-carbon economy". The first selection of "outstanding contributors to the national low-carbon economy" was jointly carried out by the China Association for social, economic and cultural exchanges and the China Industry News Association. The award focuses on the requirements of the national energy conservation and emission reduction goals, through strict selection procedures, comprehensively displays the achievements of energy conservation and emission reduction, and promotes the healthy and rapid development of China's low-carbon economy, even the same material. A total of 30 people won this honor in this selection. I learned that due to his excellent performance, Dai Qinghua was recognized as the introduced talents of the "Jiangsu Provincial high-level innovation and entrepreneurship talent introduction plan" in February 2010; In December, he was rated as "young and middle-aged expert with outstanding contributions" by Jiangsu human resources and Social Security Bureau

■ tackling key technical problems and creating low-carbon products

can gain such honor, which is inseparable from Dai Qinghua's long-term commitment to enterprise R & D and innovation

at the beginning of 2007, Dai Qinghua announced a decision to officially establish a project to develop a positive flow excavator. This is an important step in the development strategy of Sany excavator

the flow real-time matching mode of hydraulic system is one of the main core technologies of hydraulic excavator and one of the important low-carbon and energy-saving technologies of excavator. The research institute has invested the most elite R & D force. After several tests and improvements, the positive flow excavator produced has reached the international level in terms of internal quality and appearance modeling. It keeps improving and continues to experiment and improve in the process of prototype debugging. According to Dai Qinghua, during the test of the prototype in 2015, various problems occurred in the use of customers were fully considered. The standard was changed again and again, and the prototype was redesigned again and again. The molding of a machine went through countless cycles. This is exactly what Dai Qinghua said: "the excavator project is a marathon long-distance running project. The process of turning a good R & D product into an excellent commodity is actually the process of gradually forming the core R & D capability of the enterprise."

finally, the first domestic hydraulic excavator with positive flow system was successfully offline and quickly seized the market. Since then, the positive flow hydraulic system has been successfully used in 20 ton products, filling the domestic gap. This technology has been patented, and the main product sy215c hydraulic excavator has won the second prize of Jiangsu provincial scientific and technological progress award, and has passed the energy-saving technology appraisal organized by the industry association

■ long-term vision, committed to energy conservation and emission reduction

as the technical leader of Sany Heavy machinery, Dai Qinghua has obtained a number of research results in the research and development of excavators, especially in energy conservation and emission reduction

Sany Heavy Machinery Co., Ltd. independently developed the first national brand hybrid, of which 363 GW (39%) will be from the "sy215c hybrid" excavator, which integrates hybrid power, engine power optimization control, electronic control positive flow system, working device lightweight and other energy-saving technologies, achieving energy conservation of more than 30% and operating efficiency improvement of more than 25%, leading the development direction of excavator energy conservation and emission reduction

in October 2010, Sany Heavy Machinery Co., Ltd. developed China's first 7.5-ton excavator with remote control, sound control and sound control functions. This excavator, known as the "dancing spirit", adopts the world's advanced electric technology and uses rechargeable batteries and motors to replace the original engine and fuel system, which is more energy-saving, environmental friendly, quieter and more adaptable. Its appearance has effectively promoted the development of new energy technology in the construction machinery industry

excavator is known as the "pearl on the crown" of construction machinery, which has high requirements for technology, capital and talents of manufacturing enterprises, but it is also a highly risky industry. The scientific research team led by Dai Qing Huawei has overcome many key technical bottlenecks and is committed to the research of new technologies such as energy conservation and low emissions, which has greatly shortened the development cycle. At present, C8 series positive flow excavator, which is popular in the market, is the concentrated embodiment of energy-saving technical achievements. Compared with other models, the energy consumption of this machine is reduced by 10%, the digging force is increased by 9.2%, and the efficiency is increased by 8%

in 2010, Sany Heavy Machinery Co., Ltd. built the world's most advanced production line. The plant design implements the concept of energy conservation and environmental protection. In the production process, which is deeply loved by enterprises and manufacturers, it comprehensively promotes lean production mode, actively promotes assembly line production, reduces costs, and realizes energy conservation and emission reduction

facing the future, Dai Qinghua is full of confidence: "I firmly believe that one day, we can achieve a scale of 100 billion and win the global gold medal."
