Product Description
The KJ311 full hydraulic tunneling drill rig is suitable for tunneling operations in hard rock mines 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 arrangement of the drill rig ensures that the driver has a good view. The layout is balanced, and the powerful four-wheel drive articulated chassis ensures flexible, fast and safe driving in narrow lanes.
•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 maintenance parts are well protected and easy to access for maintenance.
