Hydraulic Tunnel Drill Rig

Product Description

HTT-Series hydraulic tunnel drill was driven by the diesel engine or motor, which consists of many model parts. It is widely used in the tunnel anchor, tunnel drilling, vertical well drilling and pile hole (pipe roof) in road, railway, and subway.

The feed and rotary head were driven by hydraulic motor, therefore, the air and oil consumption and total drilling cost are lower.
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.
Explosion-proof design makes it suitable to work in the tunnel.
Highly-efficient hydraulic control system used for horizontal move.
Reliable parts support high drilling efficiency.
The carriage with rollers provide for minimal wear to the drill guide.
Equipped with two hydraulic clamps is easy to load and unload drilling rods and improve efficiency.
The diesel engine and main hydraulic parts adopt imported products or famous domestic companies.
The special compensation device makes a full protection of drill rod threads.
