Portable diesel-powered DTH rig with centralized console for quarry and production blasthole drilling.
Hole Diameter: 90–152 mm
Engine: Yuchai 78 kW
Working Torque: 3200 N·m
Weight: 5500 kg
Gradability: 30°
Built for Quarry and Blasthole Work
The HW920-1 is a new-generation separated DTH surface drill rig. The rig body is matched to the DTH bit to deliver strong productivity while keeping fuel consumption and operating costs low. Efficient rig operation and an unobstructed component layout make daily maintenance straightforward.
Centralized Control, Lower Labor Cost
A centralized console puts key drilling controls in one place, improving operating efficiency and reducing the labor needed per shift. Combined with diesel-powered mobility and a smaller footprint, one rig can serve multiple locations across the site.
Proven Drilling Performance
A Yuchai YCD4T22T-105A engine delivers 78kW, driving 3200 N·m maximum working torque and 0–150 rpm swing speed. The oil-cylinder chain feed provides 15kN propulsion and 25kN lifting force, with φ60×3000mm drill pipe as standard. Adjustable leveling of 15° front and rear keeps the rig stable on uneven benches, and dust collection is available as an option.
Typical Applications: Quarry drilling, production blasthole drilling, construction and mining contracting.
