The Research Institute of Sany Automobile Hoisting Machinery Co., Ltd. is responsible for the research and development of wheeled cranes, with the development capabilities of four categories of products such as truck cranes, all terrain crane, off-road cranes and special cranes, as well as the research and test capabilities of related core technologies. 20 10 all terrain crane SAC303, the largest tonnage in Asia, has been successfully developed by Crane Research Institute, and is in a leading position in the field of over-tonnage truck cranes, and has formed a relatively complete type spectrum in QY, STC, QAY, SAC, SRC and SSC. The research institute has many core technologies, such as oil-gas suspension, electro-hydraulic power steering, single cylinder expansion and contraction, super-lifting device, large-tonnage force limiter, hydraulic control technology, large-tonnage boom manufacturing and so on. A three-level test system of vehicle test, parts test and simulation test was established. The industrial park has a vehicle test site, a vehicle inspection line, four professional laboratories and seven parts test stands, which provides strong support for new product research and development. In 20 10, SAC2200, STC500, STC 1000 and SRC550 collectively appeared in BMW Germany, demonstrating their respective technical strength and research and development capabilities. From 20 10 to 20 1 1, according to the company's development plan and the progress of internationalization, the research institute will concentrate on developing a variety of new products in four categories: truck cranes, all terrain crane, off-road tire cranes and special cranes, so as to further improve the product pedigree and enhance the market competitiveness.
Crane research institute vigorously promotes technological innovation. As of May 20 10, * * has applied for 79 patents and obtained 27 authorizations, including 33 invention patents and 7 authorizations. No pains, no gains. QAY220 all terrain crane won the title of "Top 50 Construction Machinery in China", SRC550 won the title of "Excellent New Product in Changsha", Crane Research Institute won the title of "Excellent Research Institute of Sany Group" in 2009, "Development and Promotion of Omni-directional Safety Protection Device for Large Tonnage Truck Crane" and "Development of Manufacturing Technology for Crane U-arm" won the Group's Science and Technology Innovation Award and "QY 100 Automobile".
