Our company's open-type rock TBM features fully independent core technologies in key system components, such as a main bearing design that maximizes the diameter for TBM of the same specification, a safe, flexible, and efficient arch installer, and a unique central spherical joint thrusting and gripping mechanism. It also adopts a built-in slide-type shotcrete manipulator and a unique four-claw lip seal design, with a single-pass pressure-bearing capacity of up to 10 bar, enhancing equipment performance and operational efficiency.
This type of machine is suitable for strata with relatively good rock integrity and relatively high uniaxial compressive strength, and features high construction efficiency and low cost.
