Rotary Blasthole Drilling Rig, KG430/KG430H
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. Also it features a piston motor and reinforced continuous track, both of which help this construction tool work better in ramp climbing. Wide swing and tilt angles make the unit suitable for various drilling applications. Moreover, this kind of rotary blasthole drilling rig is characterized by two rotational motors that can boost feed and pull out force and reliable operation. Thanks to the reinforced materials, the drilling machine can be transported from site to site. For environmental protection, the drilling rig consists of a dry dust collector that effectively reduces pollutants to the air.
