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