The state-of-the-art Heavy-Duty Face Drilling Rig with Three-Arm Combination for Tunnels integrates an innovative three-arm combination design, featuring dual tunneling arms and a specialized cutting arm. This cutting-edge configuration allows for the seamless execution of cutting and tunneling operations, enabling blasting and cutting holes to be completed in perfect harmony. This ingenious design enhances efficiency, reducing rock drilling time by over 20%. With the capability to achieve tunneling blast holes reaching an impressive depth of 6m and cutting holes extending to 6.3m in a single operation, it ensures remarkable progress with a single drifting footage exceeding 5.5m per cycle.
Deep single rock drilling depth
Employing an advanced composite extended propeller design, the drilling blast holes can achieve a remarkable depth of up to 6m, ensuring superior performance and efficiency.
Cutting and rock drilling coordinated operation
Featuring a sophisticated three-arm independent control system, the rig allows cutting and tunneling operations to harmonize seamlessly, maximizing efficiency and productivity.
Wide operating range
Engineered with dual propellers, our rig ensures extensive coverage across the rock drilling section, delivering exceptional performance across a broad operational range.
