Compact diesel-powered DTH rig for quarry, presplitting, and production blasthole drilling.
Hole Diameter: 90–100 mm
Engine: Yuchai 78 kW
Working Torque: 2400 N·m
Weight: 4800 kg
Gradability: 30°
Built for Quarry and Blasthole Work
The HW916-1 is a new-generation separated DTH surface drill rig designed for small and medium-sized quarries and contractors. The rig body is matched to the DTH bit to deliver strong productivity while keeping fuel consumption and operating costs low.
Compact, Mobile, Multi-Site
Diesel-powered DTH rigs offer excellent maneuverability and a smaller footprint than conventional setups, allowing one machine to serve multiple locations. With a 2 km/h travel speed and 30° gradability, the HW916-1 moves across bench and site terrain without a transporter.
Proven Drilling Performance
A Yuchai YCD4T22T-105A engine delivers 78kW, driving 2400 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. Dust collection is available as an option.
Typical Applications: Quarry drilling, presplitting, conventional production blasthole drilling, construction and mining contracting.
