KGH5AIII Open-Air DTH Drill Rig

The built-in original Kaishan screw air compressor provides stable air pressure, completely getting rid of external air sources. One rig completes relocation, positioning and drilling, reducing procurement and management costs of auxiliary equipment. No disassembly is needed for relocation with high transportation efficiency.

Thickened steel crawler and high-torque travel motor have excellent grip. The large ground clearance enables the rig to cross gravel, steep slopes and uneven roads. The maximum 25° climbing angle ensures smooth operation in complex mountainous and mining areas.

Hydraulic drive for boom, rotation and feed ensures stable movement and precise positioning. The high-pressure DTH hammer delivers powerful impact force, achieving fast drilling on hard rocks such as granite, limestone and basalt, much more efficient than traditional split drills.

The exclusive hydraulic anti-jamming circuit releases pressure and reverses automatically when the drill is stuck, preventing drill rod distortion and breakage. It reduces replacement frequency of drill bits and rods and cuts long-term operating costs.

The high-power wet dust remover adsorbs drilling dust with water mist, keeping the working site clean. The dust emission meets environmental standards of Europe, Southeast Asia and other regions, suitable for strictly regulated areas.

The industrial four-cylinder diesel engine has sufficient and stable power with economic fuel consumption. The multi-stage air filter prevents dust from entering the engine in dusty environments and extends the service life of power system.

Single-person central levers with clear function zones require no professional training. Operators can master the operation quickly, adapting to various overseas labor conditions.

Early warning and automatic shutdown protections for oil pressure, air pressure, engine overload and high temperature avoid equipment damage and personal accidents, suitable for shift work.

The modular structure divides air compressor, hydraulic parts and power components clearly. Wearing parts are easy to disassemble and replace, realizing quick on-site maintenance and repair for overseas projects
