Rotary Blasthole Drilling Rig, KG590/KG590H
Surface down-the-hole drill rig for open-pit mining
This rotary blasthole drilling rig is equipped with a 4-cylinder YUCHAI engine with low emission and less pollution. Featuring a piston motor and reinforced continuous track, this construction equipment works better in ramp climbing. Thanks to the wide swing and tilt angles, the rotary blasthole drilling rig is suitable for various drilling applications. Characterized by two rotational motors that can boost feed and pull out force and reliable operation, this extraction machine features reinforced materials strong enough for its transportation from site to site. For environmental protection, the rotary blasthole drilling is equipped with dry dust collector which can help reduce pollutants to the air.
