Hydraulic Tunnel Drill Rig is widely used in the tunnel anchor, tunnel drilling, vertical well drilling and pile hole (pipe roof) in road, railway, and subway.
(1) They are mainly used for drilling holes for water exploring and injection, gas exploring and discharging, geological exploring, bolting on slope and other drilling works.
(2)It is available of all direction position (±90°) for in underground coal mines. Adopting entire hydraulic system
(3) It consists of main frame, pump station and operational panel. With the split type structure in the main frame, it is easy to disassemble and transportation.
(4)It suits for different drilling requirements with using high-grade alloy, PDC drill bits, large diameter spiral drill rod and core drill bits.
Hydraulic Tunnel Drill Rig Characteristics
1. The feed and rotary head were driven by hydraulic motor, therefore, the air and oil consumption and total drilling cost are lower.
2. The hydraulic feed and rotary head put out the biggest feeding force and largest rotary torque, which makes it more suitable for operation in complex worksites.
3. Explosion-proof design makes it suitable to work in the tunnel.
4. Highly-efficient hydraulic control system used for horizontal move.
5. Reliable parts support high drilling efficiency.
6. The carriage with rollers provide for minimal wear to the drill guide .
7. Equipped with two hydraulic clamps is easy to load and unload drilling rods and improve efficiency.
8. The diesel engine and main hydraulic parts adopt imported products or famous domestic companies.
9. The special compensation device makes a full protection of drill rod threads.
