KT integrated open-air DTH drill rig
KT15C Integrated Open-pit Down-the-Hole (DTH) Drill Rig

introduction and Parameter:


Here is the English translation of the new paragraph:

It can drill vertical, inclined, and horizontal holes, and is mainly used for drilling blast holes and pre-split holes in large open-pit mines and rock engineering. It uses a Cummins off-road diesel engine as the single power source, which drives both the screw compression system and the hydraulic transmission system through dual-end output. The drill rig is equipped with a high-strength aluminum alloy feed beam, a variable hydraulic system, an automatic rod handling system, a drill rod floating joint module, a drill rod lubrication module, an anti-jamming system, a hydraulic dry dust collection system, a cab with air conditioning for both cooling and heating, and drilling angle and depth indication functions. The drill rig features good structural integrity, a high degree of automation, excellent drilling performance, environmental protection and energy efficiency, convenient operation, high mobility, and safe travel.
