In 2006, according to the development characteristics of China's construction machinery industry and the development trend of international construction machinery technology, especially the actual situation of China's resources, energy and environment, Tiangong Institute launched and implemented the "06 1 1 Science and Technology Strategic Project", and took remanufacturing technology research as one of the key research and development directions of Tiangong Institute. The involvement of Tiangong Institute in the research of remanufacturing technology of construction machinery has a certain scientific research foundation. Since its establishment, Tiangong Institute has been committed to the basic research of construction machinery, the research of construction machinery materials, the research of material surface engineering, the testing and standardization of parts. In surface engineering technology, Tiangong Institute is one of the earliest research and application units in China. Among them, the experimental research topic of plasma alloy powder spray welding floating oil seal ring won the scientific and technological progress award of the Ministry of Machinery, and the plasma spray welding process is at the leading level in China.
In the late 1960s, Tiangong Institute carried out the research on hardfacing of wear-resistant alloy. In 1980s, Tiangong Institute first developed the oxygen-acetylene flame spraying technology in Tianjin, and successfully applied it to the anti-corrosion of the sluice of Luanhe River Diversion Project. This project pioneered the long-term anticorrosion of Tianjin water conservancy system by thermal spraying technology, and was rated as a high-quality project. After that, Tiangong Institute successively carried out a number of applied researches on surface engineering technology, including flame spraying alloy powder wear-resistant coating on cast iron matrix; Surface reinforced stabilized soil mixer cutter head; Tool head of surface reinforced pavement mechanical milling and planing machine; Surface-strengthened trencher blades: brush plating materials and technology; Materials and technology of sand and gravel mechanical wear-resistant plate ... Among them, the bucket teeth specially designed and developed by ourselves have replaced the original imported products and are still selling well in more than 0 provinces and cities nationwide.
Tiangong Institute is the academic and technical centralized unit and national technical center of domestic construction machinery industry, with strong scientific research strength. Ding Sheng Tiangong Construction Machinery Co., Ltd., which is controlled by Ding Sheng Tiangong Construction Machinery Co., Ltd., recycled the grader used for 6 years —— 84 years —— Volume 40 of construction machinery. Special report in September 2009: Tiangong Institute: the birthplace of China's first construction machinery remanufacturing product —— the documentary of China's first grader remanufacturing project. At the beginning of 2008, PY 160CR grader was delivered to users. It marks that the "06 1 1 Science and Technology Strategic Project" of Tianjin Construction Machinery Research Institute (hereinafter referred to as Tiangong Institute) has made a breakthrough in the field of construction machinery remanufacturing, and it is the birth of the first whole machine remanufacturing product of China construction machinery. The remanufacturing center of Tiangong Institute has recovered the PY 160C and PY 160B graders that have exceeded their service life. After the remanufacturing of the whole machine and parts, through rigorous tests and performance tests after assembly, the PY 160CR grader whose product performance index reaches the factory test standard of new products is manufactured.
Remanufacturing technology based on solid scientific research has developed in the field of automobiles and parts in China, but the remanufacturing of construction machinery is still a brand-new research topic. In 2006, according to the development characteristics of China's construction machinery industry and the development trend of international construction machinery technology, especially the actual situation of China's resources, energy and environment, Tiangong Institute launched and implemented the "06 1 1 Science and Technology Strategic Project", and took remanufacturing technology research as one of the key research and development directions of Tiangong Institute.
