Jumbo underground tunnel boring drilling rig machine a sophisticated rotary drilling mechanism to excavate tunnels through various geological formations. The system utilizes a massive rotating cutter head equipped with disc cutters or roller bits, powered by high-torque hydraulic motors.
As the cutter head rotates at high efficiency drilling speed , its array of hardened steel or tungsten-carbide teeth systematically fracture the rock strata while synchronized thrust cylinders maintain forward propulsion.
High Efficiency
Enables rapid drilling and anchoring operations, accelerating project timelines.
Reduces manual labor through automated or semi-automated systems.
