KT integrated open-air DTH drill rig
KT5H Integrated Open-pit Down-the-Hole (DTH) Drill Rig
introduction and Parameter:
This drilling equipment integrates the down-the-hole drilling system and screw air compression system. It can drill vertical, inclined and horizontal holes, applicable to blasting holes and pre-split holes in open-pit mines and stone engineering.
Powered solely by a Yuchai off-road diesel engine, it drives both the screw compression system and hydraulic transmission system simultaneously. Equipped with automatic rod handling system, drill rod lubrication module and hydraulic dry dust collection system.
The drill rig features compact structure, high automation, superior drilling performance, environmental friendliness, energy efficiency, easy operation, flexible mobility and safe driving.
