Product Description
The KJ310 full-hydraulic tunneling drill rig is specially designed for steep and inclined roadways . The maximum usable slope is 25 degrees, which is suitable for hard rock mine tunneling operations with a section of 12-35 square meters.
The sturdy universal drill arm has the best cross-sectional coverage shape, and the 360- degree reversal and automatic leveling of the propelling beam facilitate quick and convenient drilling positioning. The drill boom can also be used for lateral opening of stone gates and bolt drilling operations.
The drill rig's propelling beam moves horizontally, the final hole automatically stops pushing and stopping punching, slag blowing at the bottom of the hole, electronic pulse lubrication and other functions, reducing operations and improving work efficiency.
The high-frequency percussion rock drill uses stepped pistons to optimize the shock wave transmission efficiency, increase the drilling speed , reduce the consumption of drilling tools and improve the integrity of the equipment.
The spacious working space and a series of automatic functions help the driver to concentrate on drilling safely , quickly and accurately.
All repair and maintenance parts are well protected and at the same time easy to access and maintain.
