Among them, Sany group's "core components of high-speed and heavy-duty construction machinery large flow hydraulic system" won the second prize of the 2014 National Science and Technology Invention Award, becoming the only construction machinery enterprise that won this award this year. At the Great Hall of the people, Yi Xiaogang, chief engineer of Sany group, took the stage to receive the award as the first person to complete the project.

Yi Xiaogang said that high-speed and heavy-duty construction machinery is the key equipment for the construction of major national strategic facilities. Before this project, China's Three Gorges Dam, Qinling tunnel, nuclear power and other major projects were constructed, and the high-end hydraulic parts of high-speed and heavy-duty construction machinery required were imported. By applying the technology of the invention, 53 kinds of buffer cylinders, 34 kinds of integrated hydraulic valve groups and 4 kinds of high-pressure piston pumps have been successfully developed, which fully replace the imported ones and are applied in batches

according to the detection of the national construction machinery quality supervision and inspection center, the achievement of the invention is applied to the concrete pump truck, which improves the operation efficiency by 17% and reduces the energy consumption by 11%. Based on the achievements of the invention, the world's first non decoupling oil cylinder type dynamic rammer is developed, which solves the problems of high-speed driving of oil cylinder and rapid cushioning of huge tamping energy when a 40t rammer falls freely from a height of 20m, and promotes the technical innovation of the industry

at present, the technological invention achievements have been industrialized, and a large-scale R & D and manufacturing base has been built. At the same time, the host products applying the results of the invention have been exported to the United States, Germany, Russia and other 47 countries and regions

it is understood that, as a leading enterprise in the national equipment manufacturing industry, Sany continues to build its own small-scale and scattered innovation into the core competitiveness of the enterprise, continuously makes innovation breakthroughs in the field of construction machinery, and has won the highest honor in the field of science and technology in China for many times. This award is the second time that Sany won the second prize of the National Technological Invention Award, and also the fifth time that Sany won the national science and technology award

On January 9, 2006, Sany "research, development and application of key concrete pumping technology", as China's outstanding scientific and technological achievements, won the second prize of the national scientific and technological progress award, which was the first time that Sany won the national scientific and technological progress award

On January 14, 2011, Sany "construction machinery technology innovation platform" won the second prize of national science and Technology Progress Award

on January 18, 2013, Sany "technology and application of super long boom of concrete pump truck" won the second prize of 2012 National Technical Invention Award

on January 10, 2014, Sany's "key technology and application of large tonnage series crawler cranes" was recognized, and won the second prize of 2013 National Science and technology progress for generating internal and external pressure difference of submerged samples

it is reported that the national science and technology award conference is a science and technology conference to commend and reward in the name of the state. At present, it has established the national highest science and technology award, the National Natural Science Award, the National Technological Invention Award, the national science and Technology Progress Award and the International Science and Technology Cooperation Award of the people's Republic of China
