KAISHAN KG410 and KG410H crawler DTH drilling rigs are hot-selling entry-level open-pit drilling equipment. Adopting mature industrial design and core imported hydraulic components, the machine runs steadily with low failure rate. The whole machine is compact in structure, flexible in walking and suitable for narrow construction sites. Standard 90-115mm aperture and 25m depth fully meet daily rock blasting and mining drilling needs. The optional dust collector version KG410H perfectly adapts to environmental protection inspection and green mining construction. It is the preferred cost-effective drilling rig for global small and medium mines, quarries and road construction projects.
1. Power and Environmental Upgrades
Equipped with a Yuchai off-road four-cylinder National III emission standard engine, it complies with national emission regulations, ensuring high power output whilst maintaining environmental performance. It offers enhanced adaptability to high-altitude or complex operating conditions, effectively reducing operational emissions.
2. Robust Travel and Climbing Performance
The use of a piston travel motor, combined with a folded track frame and an engineering-grade four-wheel drive system, significantly enhances operating pressure and drive stability. The high-torque travel system provides the machine with outstanding climbing capability (≤30°), enabling it to handle unpaved, rugged mountain roads or steep slopes with ease.
3. High-Efficiency Drilling and Rotation System
The dual-motor rotation mechanism substantially increases rotation torque (up to 2000 N·m) and rotational speed (120 r/min). Combined with enlarged lifting cylinders and a plate chain, it delivers powerful thrust and reliable operation, resulting in faster drilling speeds and a lower probability of drill jamming in medium-hard rock strata (f=6–20), with an economic drilling depth of up to 25 metres.
4. Robust and Durable Structural Design
Thickened, folded-edge casings enhance the machine’s overall rigidity and protection rating, effectively withstanding rockfall impacts and everyday knocks. Critical friction points, such as the guide rails, are reinforced with upper and lower wear plates, significantly extending the equipment’s service life. Additional lifting eyes ensure safer and more convenient relocation and hoisting.
5. Flexible Operation in Extreme Positions
Optimised design with enlarged tilt and boom cylinders (carriage tilt: 135° down / 50° up; drill boom tilt: 50° down / 25° up) provides the rig with a wider range of drilling angles. Whether for horizontal holes close to the ground (minimum 350 mm) or high-altitude drilling (maximum 2,840 mm), positioning is effortless, meeting the extreme positioning requirements for mine slope treatment.
6. Green Construction and User-Friendly Configuration
The KG410H model is specially equipped with a dual-cylinder dust collector, which efficiently captures dust generated during drilling to achieve dust-free operation, thereby protecting both the environment and the health of operators. The guide rails feature an inclined installation design, providing the operator with a better field of vision and clearer observation of the drilling position.
