KT7C Drill Rig

The KT7C integrated open-air down-the-hole drilling rig is advanced drilling equipment that integrates the down-the-hole drilling system and the screw air compression system. It is equipped with a Yuchai six-cylinder national three diesel engine to provide power for the two systems. It has a compact structure and good integrity. , Easy to move. High-pressure single-stage compression screw with core drill rig equipment product knowledge of the nose, the application of leading international Tom’s Y -shaped line, turnover rate (13m³ / min), pressure high (1.7 MPa), high wind pressure Pneumatic impactor provides strong power, and the rock drilling speed is 20%-50% higher than that of the air pressure drill rig.

KT7C integral high-pressure open-pit down-the-hole drilling rig is mainly used for rock work in stone works and open-pit mines.
