- The power head is equipped with a high-power top-impact mechanism, enabling efficient percussive drilling without the need for down-the-hole hammers or air compressors, resulting in high drilling efficiency and excellent borehole quality.
- Multi-angle adjustment capability meets drilling requirements at various construction angles, offering flexible and convenient operation.
- Drilling tools transmit impact energy uniformly from the outer section to the inner section, effectively reducing risks such as tool sticking or burial, thereby lowering construction risk and cost.
- Delivering high torque, high rotational speed, and strong impact power, making it suitable for most geological formations, especially cobble layers, crushed rock layers, boulder-mixed soils, and sand layers that rely on impact drilling for hole formation. The drilling rig provides fast penetration and high hole-forming quality. In water-rich formations where down-the-hole impact tools cannot operate reliably, this rig becomes the preferred construction solution.
- Equipped with a mobile operator platform, the rig offers simple and flexible operation, allowing operators to conveniently observe the borehole and ensure stable, safe construction.

- The power head provides high-power top impact, achieving effective impact drilling without down-the-hole hammers or air compressors.
- Equipped with an internationally proven variable-angle mechanism, enabling flexible angle adjustment and broad applicability for both domestic and overseas projects, especially tunnel construction.
- Uniform impact energy transmission through the drilling tools reduces drilling accidents such as stuck or buried tools, lowering construction risks and costs.
- The rig offers high torque, high speed, and strong power output, enabling rapid drilling in cobble layers, crushed rock, boulder-mixed soils, and sand layers. In formations with excessive groundwater where down-the-hole impact tools are ineffective, this rig provides an irreplaceable construction advantage.
