Crawler-mounted diesel DTH rig with centralized console and dry dust collection—built for quarry blastholes and open-pit drilling.
Hole Diameter: 110–165 mm
Engine: Yuchai 73.5 kW
Max. Working Torque: 3500 N·m
Weight: 6460 kg
Gradability: 30°
Built for Quarry and Open-Pit Work
The HW930-1 is a separated DTH surface drill rig designed for quarry blasthole drilling, pre-splitting, and conventional open-pit production. The rig body is precisely matched to the DTH bit, delivering strong productivity while minimizing fuel consumption and operating costs. It handles 110–165mm holes across a wide range of rock conditions.
Efficient Operation, Stable in Harsh Conditions
A centralized console puts control and monitoring functions within easy reach, improving operator efficiency and reducing labor cost. The crawler chassis is built to adapt to harsh working conditions while maintaining stability, with 30° gradability and ±10° leveling. The oil-cylinder chain feed delivers 20 kN propulsion and 45 kN lifting force, while 3500 N·m working torque and 0–100 rpm rotation keep penetration steady. Dry dust collection is standard.
Typical Applications: Quarry blasthole drilling, pre-splitting, open-pit mining, construction rock excavation.
