Slurry Microtunneling Pipe Jacking Tbm Mtbm

This Slurry Microtunneling Pipe Jacking TBM MTBM accomplishes long distance thrust (300 mtr ~ 1000 mtr for 1 span) and enables replacement of cutter bit at anytime as required.
Features:
1) Drive system in DH-L , installed on the periphery of the machine , generates high torque. With attached high-power cone crusher in a chamber, it is adaptable to large boulder layer as large as 2/3 of the nominal diameter to 200 MPa rock layer.
2) Cutter bit , when worn out , can be replaced from inside of the machine.
3) Optimum cutter selected in accordance with the soil property will offer effective excavating capacity and reduces surface resistance.
4) High precise excavation result can be obtained not only for linear excavation but for curved excavation with its effective center bending method steering mechanism , thrust angle sensor and detective system using optical instrument.
Diameter Available from : 1000 mm to 3000 mm
