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

This kind of rotary blasthole drilling rig is featured with a 4-cylinder YUCHAI engine with low emission and less pollution. Equipped with a piston motor and reinforced continuous tracks, our rotary blasthole drilling rig is characterized by two rotational motors that can boost feed and pull out force and reliable operation. In addition, this extraction machine is made of reinforced materials strong enough for transportation from site to site. For environmental protection, the rotary blasthole drilling rig contains a dry dust collector which will effectively reduce pollutants to the air.
