Product Name:
Hard-rock TBM 

Brief introduction of product series:
For producing Hard-rock TBMs, CRCHI makes full use of abundant experience of tunnel construction, develops its own advanced system integration technology and attends the National 863 Program’s TBM science & technology support project. Now CRCHI has already used the most advanced  designs and testing measures in terms of excavation, muck discharging and tunnel lining and other TBM key technologies, overcoming more than 30 technological difficulties in TBM’s design, manufacturing and service like long service time, consecutive advancement, design of  high-power big-torque drive system, tunnel lining, high-energy vibration active control, automatic correction of deviation of TBM posture, the preparation of high-strength wear-resistant materials. CRCHI has fully acquired TBM’s design, manufacturing as well as technology application, breaking dependence on  foreign products and technologies with regard to hard-rock tunnel construction. Hard-rock TBMs are widely used in rail transit project, water resources and hydropower project, coal mine shaft project.

Product types:
Open-type TBM, Single-shield TBM, Double-shield TBM

Product Features:
Advance borehole drilling; advance support; direct observation of  lithology change; easy to draw geological map.
Hardox plate, composite chromium-carbide wear-resistant plate as well as hard alloy block with high wear resistance are materials of the cutter-head, which ensures long service time.  
Double row cylindrical roller thrust bearing is used in the masterdrive, ensuing long service lifetime and high safety.
