Micro Tunnelling The head section is the core of the push bench of driving which displays the main technology of the machine. The machine adopts gear driving and motionless sealing equipment which is self-developed by our company and first initiated in our country. Power generated from the motor is driven to reduce the rotating speed of the cutter head, decreasing the torsion and increasing the torque force, making the cutter head move irregularly, achieving the effect of low rotating speed but great torque force, breaking stones finally. The construction mainly deals with complex kinds of s
