Kaishan DTH Drilling Rigs

Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.

Kaishan KG410 / KG410H Crawler DTH Drilling Rig (90–115 mm Open-Pit & Quarry)

The Kaishan KG410 and KG410H are industry-proven crawler-mounted down-the-hole (DTH) drilling rigs engineered for open-pit mining, aggregate quarries, and road construction. Featuring a standard Φ90–115 mm drilling diameter and a 25 m economical drilling depth, these rigs deliver up to 2000 N·m rotation torque and superior ≤ 30° climbing capability. Equipped with an off-road 59 kW Yuchai China III diesel engine and an optional dual-cylinder dry dust collector (KG410H), the series ensures low operating costs, maximum uptime in hard rock (f=6–20), and full environmental compliance. Direct factory pricing, matched screw air compressor packages, and genuine spare parts are available worldwide.
  • Product Detail Introduction

Key Engineering & Operational Advantages

1. High-Torque Dual-Motor Rotary Head

Equipped with a dual-motor rotation system delivering up to 2000 N·m torque and 0–120 rpm revolving speed. Combined with an enlarged feed cylinder and heavy-duty plate leaf chain, it minimizes drill pipe sticking in fractured, medium-to-hard rock formations (f=6–20).

2. Robust Tramming & 30° Gradeability

Powered by a high-pressure plunger piston tramming motor and a heavy-duty folding track frame. The engineering-grade 4-wheel drive track chassis delivers stable traction, 280 mm ground clearance, and up to 30° climbing capacity on rugged mountain haul roads.

3. Emission-Compliant Yuchai Off-Road Engine

Driven by a Yuchai YCD4R23T8-80 four-cylinder diesel engine (59 kW @ 2400 rpm) meeting National/China III non-road emission standards. Provides high altitude adaptability, low fuel consumption, and reliable power output for harsh quarry environments.

4. Multi-Angle Boom & Extreme Drilling Geometry

Optimized hydraulic cylinders provide a wide articulation envelope: carriage tilt down 135° / up 50° and boom swing left 44° / right 45°. Capable of horizontal toe-hole drilling at heights from 350 mm up to 2950 mm for precision bench and slope stabilization.

5. Reinforced Impact-Resistant Structure

Thickened folded-edge profile housing protects sensitive hydraulic valves against rockfall impacts. Wear-resistant guide rail wear plates, reinforced feed chains, and factory-welded lifting eyes ensure prolonged service life and safe crane transport.

6. Eco-Friendly Dual-Cylinder Dust Collection (KG410H)

The KG410H model incorporates an integrated high-efficiency dual-cylinder dry dust extraction system. Captures silica dust directly at the borehole collar, complying with strict occupational health and green mining environmental inspections.

Primary Applications & Working Conditions

Open-Pit Quarrying

Ideal for limestone, granite, and sandstone quarries requiring continuous 90–115 mm blast holes with rapid bench positioning and low fuel consumption per meter.

Surface Mining & Earthwork

Handles production blasting in small-to-medium coal mines, iron open-pits, and foundation excavations with high ground clearance on uneven terrain.

Highway & Infrastructure Cuttings

Flexible horizontal and toe-hole capabilities allow precision pre-split and slope stabilization drilling along steep highway and railway rock cuts.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between Kaishan KG410 and KG410H?

A: The core mechanical chassis and drilling capabilities are identical. However, the KG410H features a factory-fitted dual-cylinder dry dust extraction system that actively suctions drilling dust from the borehole collar, meeting strict municipal and national environmental protection standards.

Q: Which air compressor should be paired with the KG410/KG410H?

A: The drill rig requires an air volume of 10 to 17 m³/min. We recommend pairing it with a medium-to-high pressure portable diesel screw compressor, such as the Kaishan LGCY-18/17 (18 m³/min @ 1.7 MPa) or KSCY-550/14, to ensure maximum penetration rates in hard rock.

Q: Can this machine drill horizontal holes close to the ground?

A: Yes. With its wide-angle boom and carriage cylinders, the KG410 series can achieve horizontal toe holes at a minimum ground height of 350–750 mm and up to 2950 mm for upper bench stabilization.

Q: How is the equipment shipped internationally?

A: Due to its compact transport dimensions (6,000 × 2,100/2,350 × 2,000 mm) and weight under 5 tons, the KG410/KG410H can be conveniently loaded into standard 20GP or 40HQ shipping containers or transported via flat-rack and Ro-Ro vessels.
