In November 23, 2010, the Fifth China International Engineering machinery, building materials machinery, engineering vehicles and Equipment Expo (Bauma China 2010) was opened in the New International Expo Center in Shanghai, with a total of 1858 exhibitors. This event is a milestone in the overall rise of China's construction machinery industry. Chinese manufacturers show stronger competitiveness and foreign brands' share in the Chinese market has been further compressed. Xugong Group introduced the world's largest QAY1200 type 1200 ton full road crane at the exhibition, and the largest XGC28000 type 2000 ton crawler crane in Asia. The 31 group has launched 1600 tons crawler crane and SAC12000 type 1200 ton all terrain crane. ZOOMLION launched the world's largest horizontal arm mounted self elevating tower crane, D5200-240. These sophisticated products attracted 130 thousand spectators.
Xugong Group is the largest construction machinery enterprise in China. In 2009, it realized 50 billion 518 million yuan of business income and 3 billion 500 million yuan of profits and taxes. Its products include crane, excavator, loader, roller, concrete machinery, pile machinery, railway machinery, fire fighting equipment, special vehicles, hydraulic components and so on. The products are exported to more than 130 countries and regions in the world. The total number of employees is nearly thirty thousand, with 11 R & D centers and more than 2000 R & D teams.
Xuzhou Heavy Machinery Co., Ltd. is a core subsidiary of Xugong Group, mainly to develop cranes. Founded in May 1943, the factory was originally called the eighth military factory in Lunan, located in Hulu gully, Junan, Shandong province. It was first known as the Huaxing iron factory. It was at that time a factory to repair simple firearms and flying machines. In May 1953, the factory moved to Xuzhou from Sinpo (now Lianyungang city) in Xinhai City, and merged with the iron and iron factory of Xuzhou Industrial Company as Xuzhou agricultural machinery plant. In 1953, the first working machine in Xuzhou was produced - 35 tons of tilting press, which began to produce double plow plough in 1954. The tower crane began to be produced in 1957. The factory began to develop from agricultural machinery to lifting machinery. In 1958, the factory scale had developed to 2680. In October 22, 1958, Bo Yibo, vice premier of the State Council, inspected the factory and proposed to change the factory name to "Xuzhou heavy machinery factory", which has been used until September 2004.
In 1962, the Xuzhou heavy machinery plant accepted the development task of the Q51 type 5 ton truck crane, which was issued by one bureau and five bureaux. In 1963, the Q51 type 5 ton mechanical truck crane was successfully developed. Since then, in the past 20 years, Xu Zhong Du has been dominated by Q51. In 1967, Xuzhou heavy duty plant successfully developed the Q2 10 10 ton hydraulic truck crane, which marked the development of the Xu heavy truck crane from the mechanical transmission to the full hydraulic transmission. In 1968, commissioned by the PLA General Logistics Department, the Q2-5H type 5 ton hydraulic truck crane was developed. In 1973, Xu began to develop 8 tons of hydraulic truck cranes for the development of hydraulic truck cranes. In 1974, the Xuzhou heavy plant successfully produced 16 tons of hydraulic truck cranes. In 1975, the special chassis of 8 tons and 16 tons of truck cranes were successfully manufactured, filling the blank of China's special chassis which could not produce large tonnage cranes.
In 1980, Xuzhou heavy-duty machinery plant introduced 16 tons of Japanese truck crane chassis and bulk carrier, began to import and absorb foreign technology, introduced the design and manufacturing technology of Japanese multi field, MITSUBISHI, Nissan, Kato truck crane, and German Liebherr company all road car crane design and manufacturing technology. Constantly updating and replacing, the technical level has been continuously improved. After 1981, the chassis of the Xu heavy truck truck was mass produced, which solved the passive situation of large and medium tonnage cranes depending on imported chassis. In 1980, Xu began to change the small and full production mode, and began to specializes in production. It became a professional factory of 5-50 tons hydraulic truck crane, its special chassis and other engineering machinery. Products have QY12, QY20, QY32, QY40, QY50, get off and QYD10 vertical bar crane, JC6 mixer, QY8A, QY25 car crane, in 1986, Xuzhou heavy machinery factory became the first hundred million yuan enterprise in the engineering machinery industry. In 1987, the QY16 truck crane was sold to the United States.
