KJ311 hydraulic top hammer drilling rig for tunneling

 

Advantages

1.KJ311 is a hydraulic drifting jumbo designed fo12-35 m2 cross section in underground mining operations.  2.Robust universal drilling boom creates ideal face drilling coverage. Automatic parallelism and 360o roll-over enable easy, fast and accurate positioning for face drilling, side way drilling and bolt hole drilling.  3.The layout of components provides excellent vision for the operator in drilling and traveling.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.  4.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. 

5.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. 

 

6.All service points are easily accessible, which simplifies daily routine maintenance.

 

Application:

It can be used for the construction of railway, road, hydroelectrical power station, building, as well as the quarry and surface mine.
