1.Picture of Kaishan KJ313 used Jumbo drill for tunnel construction from  Montabert hydraulic drifter drill cross section 13m*12m

KJ313 -type full-hydraulic tunnel jumbo is applicable for hard-rock mine tunnelling operation of 12-35m2 section, which is specially designed for hitting anchor rod at the same time. It can be used to drill 2.2m-depth bolt hole in the roadway with the height of 4m.

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 drilling and positioning. Meanwhile, the drill boom can be also used for laterally opening crossdrift 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 travels flexibly, quickly and safely in the narrow roadway.

High-frequency impact jackdrill 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.

 2.Advantages:

Robust universal drilling boom creates ideal face drilling coverage. Automatic parallelism and 360o roll-over enable easy, fast and accurate positioning for face drilling, sideway drilling and bolt hole drilling. 

The layout of components provides excellent vision for the operator in drilling and travelling.Powerful and well balanced 4-wheel drive chassis allows the rig to move through limited space and tough terrain in the mines. Duo-circuit service brake and enclosed multi-disc parking/ emergency brake ensure safety in tramming and on ramp slope. 

Field proven high frequency hydraulic drifter delivers high performance. Trapezoid shaped percussion piston optimizes shock wave transfer efficiency, enhancing penetration and decrease drilling consumables costs. 

Comfortable operator station provides safe working condition. Many automatic features simplified the drilling control and helps the miners to concentrate on fast and accurate drilling.  All service points are easily accessible, which simplifies daily routine maintenance.
