Rotation unit (hydraulic drive head) adopted the France technique. It is driven by dual hydraulic motors and changed speed by the mechanical style. It has wide range speeds and high torque at low speed, satisfying different project construction and drilling processes.

The rotation unit has a stiffer spindle, transmitting accurately and running steadily, which offers distinct advantages in deep drilling applications.

The feeding and lifting system uses a single hydraulic cylinder driving the chain. Featuring long-distance characters, it is highly suited for the long rock core drilling process.

The rig features high lifting speed, which significantly decreases auxiliary time and improves overall drilling efficiency.

The V style orbit in the mast ensures sufficient rigidity between the top hydraulic head and the mast, delivering excellent stability at high rotation speeds.

The hydraulic driving head is engineered with the flexibility to move away from the drilling hole when required.

Equipped with a clamp machine system and an unscrew machine system, bringing great convenience to rock core drilling operations.

The hydraulic system adopts advanced France technique, ensuring high reliability and stable performance during demanding tasks.

Mud pumps are controlled via a hydraulic valve. All control handles are concentrated on the control panel, making it easy to manage down-hole situations.
