Present situation of rotary drilling rig in China

Rotary drilling rig first appeared in calvert Company before World War II, and developed in Europe after World War II. 1948 Mattel of Italy first started to develop, and then Italy and Germany also started to develop, and it developed rapidly in Japan in the 1970s and 1980s. At that time, Japan called it rotary bucket piling, also called EarthDriII, which was quite common in Germany and Japan. China imported a working device from Japan in the early 1980s and installed it on KH- 125 crawler crane. 1984 Tianjin exploration machinery factory introduced the rotary drilling rig of RDI company of the United States and digested it. 1987, the products of Italian geo-engineering company (SOILMEC) were exhibited in Beijing Exhibition Hall for the first time. 1988, Beijing Urban Construction Machinery Factory developed an attached rotary drilling rig for crawler crane with a diameter of 1.5m according to the prototype of earthwork company.

During the period of 1994, Zhengzhou survey machinery factory introduced the production technology of attached rotary drilling rig from BSP company in England, but it did not form mass production. 1992, Baoe Company set up a representative office in Beijing, China, and started its business in China. 1995, Bao 'e Tianjin Mechanical Engineering Co., Ltd., a wholly-owned subsidiary, was established in Tianjin to assemble Bao 'e BG20 rotary drilling rig suitable for China market.

1998, Shanghai baoe Jintai construction machinery co., ltd, a sino-german joint venture, was established in Shanghai to produce and assemble BG 15 and BG24 rotary drilling rigs. From 65438 to 0998, Xugong Group began to independently develop RD 18 rotary drilling rig, which was successfully trial-produced in 1999 and put into mass production. In recent years, rotary drilling rig has made rapid development in China. Later, Beijing Jingwei Juli and Sany Heavy Machinery also set foot in the production of rotary drilling rigs, and there are nearly 20 rotary drilling rig manufacturers at home and abroad.

Driven by the Qinghai-Tibet Railway project and the Beijing Olympic Games project in 2003, the market awareness of rotary drilling rig industry has increased rapidly, and the market capacity has expanded dramatically. The soaring market demand has attracted large domestic construction machinery enterprises to enter, and Sany, Xugong, Zoomlion and He Shan Intelligent have set foot in one after another, and rapidly expanded their market share. After 2005, domestic brands of rotary drilling rigs have basically replaced foreign brands. Since 2006, the sales of rotary drilling rigs have been growing by leaps and bounds year after year. Especially in 2009, there were as many as 30 domestic rotary drilling rig manufacturers, which launched nearly 200 models of products, with a market share of nearly 4,000 sets, and the market competition was unprecedentedly fierce.
