KT integrated open-air DTH drill rig
KT11 Integrated Open-pit Down-the-Hole (DTH) Drill Rig

introduction and Parameter:

Capable of drilling vertical, inclined and horizontal holes, it is mainly used for blasting holes and pre-split holes in large open-pit mines and rock engineering projects.Powered solely by a Cummins off-road diesel engine, it drives both the screw compression system and hydraulic transmission system via dual-end output. It is equipped with an automatic rod handling system, floating drill rod slide module, drill rod lubrication module, anti-jamming system, hydraulic dry dust collection system, air-conditioned cab with heating and cooling, and optional drilling angle and depth indication functions.The drill rig features a compact structure, high level of automation, excellent drilling performance, environmental friendliness, energy efficiency, easy operation, flexible mobility and safe driving.
