XCMG XTR7/260 -- the biggest cutting height tunnel boring machine in China successfully offline 

Recently, the company independent research and development of domestic maximum cutting height of tunnel boring machine XTR7/260 assembly line, marking the Xugong in tunnel boring machine design, manufacturing and other aspects and a major step forward, adding weight to expand the market strong tunnel.

XTR7/260 tunnel boring machine designed for medium and soft rock surrounding rock tunnel, cutting range reached 7.2 x 7.5 meters, mainly used in railway, highway and other large section tunnel engineering. The models increased the first conveyor shovel board, hanging on the adjusted 2 transport material transport device, increase the supporting platform, and the independent bracket for cooling device, the voltage level is increased from 380V to 1140v. The shovel plate with feeding function is designed to make the width of the shovel plate reach 5.6 meters.

XTR7/260 greatly improves the work efficiency, and adds a bright XCMG for the national tunnel mechanization construction!
