Down-the-hole drill rig for open-pit mining

This machine integrates a hydraulic long hole drilling rig and a screw air compressor. The compressor consists of a single-stage high-pressure air end that delivers 13,000 L of air per minute at up to 246.5psi, which can provide energy to KT7C’s high-pressure down-the-hole hammer. Thanks to this, the rig drills rocks 20%-50% faster than those equipped with medium-pressure air compressor. The machine is powered by a Yuchai off-road engine that meets China Stage III emission standards. With so many distinctive features, the rig is easy to use and to be transported from site to site.
