Suitable for excavation drilling and anchor rod drilling operations in 35m ² -195m ² highway and railway tunnels, pumped storage power stations, hydro-power stations, reservoir irrigation tunnels, and underground caverns.
Precision: computer-controlled drilling system, automatic positioning and drilling, precise control of the angle of the advancing beam and depth of the hole, small amount of over-digging. Safety: one machine only needs 3 people to operate, the workers are far away from the palm surface, the construction is safer. High efficiency: automatic drilling, automatic anti-jamming, fast drilling speed of single hole, improve construction progress. Stability: rock drill, main hydraulic components and chassis transmission system are all of well-known brands. Humanized design: fully enclosed cab, humanized design for operation, reducing noise and dust damage.
