Integrated Surface DTH Drilling Rig, KT5D
Down-the-hole drill rig for open-pit mining
This machine integrates a hydraulic long hole drilling rig and a screw air compressor. With a special design, it can be used for either vertical drilling or angle drilling, which is suitable for drilling blastholes and pre-splitting holes in open-pit mines and stonework sites. Powered by a Yuchai off-road engine that meets China Stage III emission standards, the drilling machine works by activating the compressor and a hydraulic machine through a flywheel and a rear PTO shaft. The machine is equipped with a hands-free rod handling system, a floating clamp, a rod lubrication module and a hydraulic dry dust collector. Angle indicator is also available. As you can see, this machine is highly automated and can be efficiently used in drilling rocks. It is easy to use and convenient to be transported from site to site.
