Parts of China's Construction Machinery Transmission yuan starting in 1960, supporting enterprises in Hangzhou, was established "Hangzhou Gear Factory", that is now China's largest manufacturer of construction machinery gearbox - Hangzhou Advanced Gearbox Group Co., Ltd. Construction Machinery Transmission Company  Colored tile forming machine  (hereinafter referred to Hang Hang teeth teeth group or engineering machinery transmission branch). Followed by Hang tooth reconstruction, in Chengdu, Sichuan, China set up another of the largest construction machinery manufacturer, one of the transmission, "Sichuan gear factory." From the early seventies to the eighties, in particular, to the next decade, as China's construction machinery industry, the rapid development and transmission yuan components has also been rapid development. Conversion businesses, aviation industry, Changsha Zhongnan Transmission Machinery Factory (the "South Drive"), Ganzhou rings gear box factory, Shaoxing Advance Gearbox Co., Ltd., a group of cross transmission companies have been established, so that one part of China's major transmission yuan The transmission is basically formed a system for manufacturing enterprises. In the drive axle, the industry has set up during this period there is a typical representative of two professional drive axle manufacturer. One is, Shandong Feicheng Bridge Roll forming machine   plant, in February 2001 and converted into a privately-run city of clouds of fat Yu Construction Machinery Co., Ltd.. Another is the Jiangxi Fenyi bridge factory, later reformed into private enterprise, the two companies to produce the main loader drive axle. In addition, the Axle Plant of Anqing, Anhui Heli Company Limited (the "Anqing axle"), specializing in the production forklift Bridge, the current annual sales volume has reached the bridge forklift at about 100,000 or so, is currently China's largest forklift manufacturers supporting the bridge. There are some enterprises, such as the Xuzhou-Liang Yu Transmission Machinery Company Limited ( "Xuzhou good feather"), Yang City Hanjiang David Construction Machinery Co., Ltd. (referred to as "states David Young"), such as bridges, box integrated production enterprises. After the nineties with the establishment of joint ventures, wholly-owned transmission yuan parts manufacturing companies, such as Glazed Tile Forming Machine   cloud Feicheng woo companies and Hong Kong joint venture specializing in the production loader bridge, "Feicheng Jincheng Axle Co., Ltd.", LIUGONG with the German ZF joint venture high level of specialized production of bridges, box "Liuzhou ZF Machinery Co., Ltd.," Xugong a joint venture with the USA and the United States Chi-professional production of various kinds of construction machinery drive axle "Xuzhou Meritor Axle Co., Ltd.", as well as Italy cards Ferraro in Qingdao, China to establish a wholly-owned enterprises "Carraro (Qingdao) Transmission Co., Ltd." and so on, to now include the production of hydraulic torque converter-based transmission yuan parts enterprises, and a total of about 30 or so, in 2007 its sales had reached 50 billion yuan, basically formed a small part of China's  Roll shutter door forming machine  yuan trades transmission.
