KT integrated open-air DTH drill rig
KT30 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 and inclined holes, and is mainly used for drilling large-diameter blast holes and pre-split holes in large open-pit mines and rock engineering. It uses a Cummins diesel engine as the single power source, which drives both the screw compressor system and the hydraulic transmission system through dual-end output. Equipped with an aluminum rail guide, it ensures excellent borehole straightness. It is fitted with a two-stage screw compressor for strong stability of the air circuit system. The long drill rod reduces the number of rod changes. It also includes a drill rod lubrication system, a dry dust collection system, drill rod thread protection, drilling angle and depth display, an automatic rod handling device to reduce labor intensity, and an air-conditioned cab for a comfortable working environment, as well as an automatic anti-jamming valve to reduce the risk of jamming. All controls on the drill rig are electric control systems, offering high sensitivity and labor-saving operation. The drill rig features good structural integrity, a high degree of automation, excellent drilling performance, environmental protection and energy efficiency, convenient and flexible operation, and safe travel.
