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

This type of 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, these designs help the drilling machine work better in ramp climbing. Thanks to the wide swing and tilt angles, our 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, the surface drill rig slide base is arranged in a special way for easy operation and better visibility. For more convenient transportation, the rotary blasthole drilling rig is featured with reinforced materials.
