KT integrated open-air DTH drill rig
KT5D Integrated Open-pit Down-the-Hole (DTH) Drill Rig
introduction and Parameter:
An integrated drilling device combining down-the-hole drilling and screw air compression systems. It drills vertical, inclined and horizontal holes for blasting and pre-split holes in open-pit mines and rock engineering.
Powered by a single Yuchai off-road diesel engine, it drives both screw compression and hydraulic transmission systems. Fitted with automatic rod handling, drill rod lubrication and hydraulic dry dust collection systems.
The rig boasts solid structure, high automation, excellent drilling performance, energy conservation, easy operation, flexible mobility and safe driving.
