Description of Underground KJ311 Full hydraulic New multi Purpose excavator top hammer construction drilling rig
KJ311 full hydraulic Drill Rig is suitable for 12-35 square meter section of the hard rock mining tunneling operations.
Rugged universal boom section has the best coverage shape, advancing beam 360-degree flip and automatic flat allowing quick and easy to achieve drilling positioning. But it can also be used boom laterally open Shimen and anchor drilling operations.
Drill driver arrangement ensures good view. Arrangement balanced, powerful four-wheel-drive chassis is hinged in the narrow tunnel can ensure flexible, fast, safe driving.
High impact drilling machine cascade optimized piston shock wave transmission efficiency, improve the drilling speed and reduces solder consumption and improve the operability of the device.
Spacious work space and a series of automatic functions help the driver concentrate on safe, fast and accurate drilling.
Various maintenance parts are well protected at the same time accessible and easy to maintain.
