Description
KJ311-type full-hydraulic tunnel jumbo is applicable for hard-rock mine tunneling with section of 12-35m2.
Solid 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 boring and positioning. Meanwhile, the drill boom can be also used for laterally opening cross drift and anchor-hold drilling operation.
The arrangement of drill rig 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 travels 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 is protected well and easy to access and maintain at the same time.
