KJ 211 Hydraulic Top Hammer Drilling Jumbo
Function and feature
KJ211 is predetermined to be used for mining, preparation work and tunneling. It is a hydraulic drilling jumbo for independent operation, which can be used for drilling vertical, inclined and horizontal blast hole. Applicable for hard-rock tunneling operation of 12-35m2 section;
Solid and reliable universal arm is equipped with the best section covering shape, and the propulsion beam can turn over by 360°and level off automatically, so as to be convenient for quickly achieving drilling and positioning.
Meanwhile, the arm can be also used for laterally opening cross drift and anchor-hold drilling operation.
The arrangement of drill carriage shall ensure the view of the manipulator in good condition.
The arrangement is in balance condition. The strong four-wheel-drive articulated base plate can ensure that the drill carriage is able to travel flexibly, quickly and safely in the narrow roadway.
High-frequency impact jack drill optimizes the transmission efficiency of impact wave, enhances the drilling rate, reduces consumption of drilling tools and enhances the serviceability rate of equipment by adopting stair piston;
Spacious operation space and a series of automatic functions are conducive for the driver concentrating to safely, quickly and accurately drill.
Each maintenance part has been protected well and shall also be easy to maintain at the same time.
