Plateau cold large diameter hard rock roadheader "Plateau Pioneer" successfully off the line: the cutter head diameter is 10.23 meters, and the length of the whole machine is about 300 meters.

Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, September 29, according to the website of the State-owned assets Supervision and Administration Commission, on September 26, the plateau cold and large diameter hard rock roadheader "Plateau Pioneer" (China Railway 1197), jointly developed by China Railway Industry, a subsidiary of China Railway Corporation, and the 14th Bureau of China Railway Construction, was successfully offline in Zhengzhou.

CTOnews.com learned that this is another large-diameter hard rock roadheader produced by China Railway Industry after "Snow Vanguard", "Zhongdan" and "Plateau Navigation" for plateau alpine railway projects.

The data show that the cutter head diameter of the hard rock roadheader "Plateau Vanguard" is 10.23 meters and the length of the machine is about 300 meters.

In order to better solve the construction difficulties such as long tunneling distance, high construction height, high rock strength and passing through the broken zone, the R & D team applied a variety of technologies, such as intelligent auxiliary tunneling, mainframe vibration monitoring, high-performance edge calculation terminal, cutterhead infrared monitoring, advanced geological prediction and so on, which has become another breakthrough in the application of domestic high-end equipment technology in high-altitude and cold tunnel projects.
