Technical Performance And Features：

1.Wide range application: t is not only suitable for all kinds of soil, but also suitable for medium coarse sandsoft to medium sandstone. 
2.Low-speed and high-torque transmission mode, the cutting force of the cutter head is high, and theoverload coefficient can reach more than 3 times. 
3.There is an independent and perfect soil water grouting system, which can be used to modify theexcavatlon surace.
4.Full-face cutting, the opening rate is 65%, and the earth pressure is more realistic.
5.The ground coverage is only need 1.5 times of the pipe diameter.
6.By screw conveyor, highly excavated with large particle size.
