The Down-the-Hole Hammer Kit places a hydraulic rotor between the pile driver hammer and the vertical sliding column, enabling efficient drilling through rock, unreinforced concrete, or dense conglomerates. When not in use, the rotor and Down-the-Hole Hammer Kit can be detached from the hammer and set to standby, ready for quick re-engagement. This system allows seamless switching between drilling and driving functions without the need to disassemble heavy components, enhancing crew safety, operational efficiency, and minimizing setup time for versatile applications.
