BEST-DX2A Core Drilling Rig Full Hydraulic For Geological Mining Drilling

BEST-DX2A Core Drilling Rig Full Hydraulic For Geological Mining Drilling

BEWT-DX2A Full Hydraulic Core Drill Rig adopts lightweight and modular design, and is compact in structure, rational in overall
arrangement, easy in operation, high performance and low maintenance. It is mainly used in rope coring drilling process with
diamond bit , for drilling needs of various strata, with a wide range of adaptability.

1.The rig adopts full hydraulic driving system and moves with its steel crawlers.
2.The drill head adopts the top drive structure. The rotation of drill head is set with 2 gear stepless speed adjustment. Drill
head is driven by cylinder directly and set with lateral translation mechanism.
3.The mast is foldable, with a touchdown function, and the mast can be extended as required.
4.The rotation of the spindle is driven by a single motor, with high operation efficiency.
5.A hydraulic clamp and centering guide are adopted at the position above the drilling hole.
