Engineering Advantages & Performance Highlights
1. Cummins High-Output Powertrain (92 kW)
Equipped with a turbocharged Cummins QSB3.9-C125 industrial diesel engine (92 kW / 2200 rpm), providing massive power reserve, low specific fuel consumption, and consistent penetration speed in tough rock up to f = 20.
2. Double-Motor High-Torque Rotary Head
Dual hydraulic drive motors double the output rotary torque to 4500 N·m while maintaining smooth 0–110 rpm speed regulation. This prevents drill pipe stalling when drilling large-diameter holes (up to 202 mm).
3. Folding Frame Track with ±8° Self-Leveling
Heavy-duty steel crawler chassis features a folding frame structure and hydraulic track pitch leveling (±8°). Combined with 440 mm ground clearance, it keeps the drill mast vertical on steep slopes and uneven benches.
4. Heavy-Duty Feed Mechanism & Lifting Force
An expanded oil cylinder-leaf chain feed mechanism provides a 4010 mm long feed stroke and 25 kN lifting force, significantly speeding up 3-meter drill rod handling and deep-hole tool recovery.
5. Large Multi-Stage Dust Collection (KG610H)
The KG610H configuration integrates a heavy-duty cyclone/dry dust collection system to capture respirable silica dust at the hole collar, complying with strict international green mining regulations.
6. Reinforced Boom Articulation & Limiting Reach
Expanded boom pitch and heavy lift cylinders allow wide-angle articulation (beam tilt 185°, swing 80°). Minimum horizontal hole height reaches 900 mm and maximum reach extends to 2850 mm for versatile bench trimming.
Target Industrial Applications (Rock Hardness f = 6 – 20)
Engineered for continuous heavy-load operations across demanding open-pit mining and major infrastructure sites:
- Open-Pit Metal & Non-Metal Mining: Large-scale blast hole drilling in iron ore, copper, gold, coal, and limestone mines.
- Quarry & Aggregate Production: Heavy bench blasting, perimeter pre-splitting, and secondary boulder reduction.
- Major Civil Earthworks: Deep rock excavation for highways, railways, hydroelectric dams, and power station foundations.
- Geotechnical Engineering: High-wall slope reinforcement, rock bolting, and anchor cable hole drilling.

Frequently Asked Questions (FAQ)
What is the main difference between Kaishan KG610 and KG610H?
The primary difference is that the KG610H is factory-equipped with a high-capacity cyclone dry dust collection system and has an overall width of 2800 mm (weight: 7600 kg), whereas the standard KG610 does not include the dust collector and has a narrower width of 2250 mm (weight: 7100 kg).
What portable air compressor is recommended for the KG610/KG610H?
With an air consumption requirement of 15 to 26 m³/min and matching a K5 (5-inch) DTH hammer, we recommend pairing the KG610 series with a Kaishan portable diesel screw air compressor delivering 18–25 bar pressure and 18–24 m³/min flow (such as KSCY-550/18 or LGCY-22/20).
Can the KG610 drill horizontal and pre-split angle holes?
Yes. The rig features wide boom articulation with a beam tilt of 185° and boom swing of 90°, allowing horizontal hole drilling at heights between 900 mm and 2850 mm, as well as inclined angle drilling for pre-split blasting.
