Main feature

1, Adopt full hydraulic power head transmission, infinitely variable speed, high drilling efficiency, low labor intensity.

 

2,  The hydraulic system of drilling rig is stable and reliable with long service life.

3, The power head adopts hydraulic variable-speed mode with high and low grades, which can meet the requirements of various formations and different drilling techniques.

4. The drill has the function of crawler walking by itself, and the equipment can be moved easily and quickly.

5.  Equipped with a slewing mechanism, the hole can be manually transferred to the side of the track when needed.

6, Compact structure, centralized operation, convenient and safe.

 

      7.The column can be stretched back and forth to meet the bolt construction requirements.

      8,Optional clamping device reduces labor intensity and operation time of loading and unloading drill pipe.
