Integrated Surface DTH Drilling Rig, KT12
Down-the-hole drill rig for open-pit mining
This machine is powered by a two-terminal engine that meets China Stage III emission standards. The engine activates the compressor and hydraulic transmission system, through which the machine can drill holes ranging from 115-152 mm in different angles, making it the best choice for operators when considering drilling blastholes and pre-splitting holes in open-pit mines and stonework sites. With a hands-free rod handling system and a lubrication module, the machine can be operated by a single person who can control the machine through a console in the cab. The machine can drill holes in a better way with its interior anti-jamming system and an angle and depth indicator. It is also equipped with an advanced dust collector, a big cab, a powerful air-conditioner and a quality speaker, providing a cozy working evniornment for operators.
