Surface down-the-hole drill rig for open-pit mining

The rotary blasthole drilling rig is equipped with a 4-cylinder YUCHAI engine with low emission and less pollution. The construction machine features a piston motor and reinforced continuous track, both of which help the drill rig work better in ramp climbing. Owing to the wide swing and tilt angles, the extraction tool is suitable for various drilling applications. Characterized by two rotational motors that can boost feed and pull out force and reliable operation, this surface drill rig features reinforced materials strong enough for its transportation from site to site. Additionally, the rotary blasthole drilling rig is equipped with a dry dust collector that can help reduce pollutants to the air.
