Rotary Blasthole Drilling Rig, KGH3AⅢ
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. Featuring a piston motor and reinforced continuous track, this construction machine works better in ramp climbing. A special boom has been designed for vertical drilling. A user-friendly operating interface allows an operator capable of replacing drilling rods by himself. The rotary blasthole drilling rig is characterized by two rotational motors that can enhance feed and pull out force and reliable operation of the machine. Thanks to the reinforced materials, it will not be a tough task to move the rotary blasthole drill rig from site to site. Additionally, an improved cylinder in this drilling equipment ensures reliable operation.
