       JD_200B drilling rig

                                                 

JD-200B drilling rig is a vertical shaft rotary, portable and multi-purpose engineering investigation and construction drilling rig with mechanical transmission and hydraulic feed. Engineering geological survey work, shallow oil and natural gas exploitation, mine tunnel ventilation, drainage, and construction of small-diameter foundation pile holes, etc., general survey and exploration of solid deposits, inspection holes of various concrete structures for blasting holes, etc. Depending on the stratum, drill bits such as diamond, cemented carbide, and spiral can be used for drilling. It has the advantages of compact structure, light weight, small size and good disassembly, and is one of the rare ideal equipments to meet the new market demand.
Main Features
1. Select a more reasonable speed range, there are eight speed series, centralized speed change, mutual self-locking
2. Low speed, high torque, wide application range, strong drilling ability, suitable for drilling rig sampling, well drilling and pile foundation construction. It is suitable for both engineering geological survey and diamond core drilling.
3. The drilling rig has two reverse speeds, which is convenient for handling faults safely.
4. The gyrator chuck adopts a hydraulic chuck, which is reliable in clamping, does not damage the active drill pipe, and can implement non-stop down-rod.
5. Hydraulic feeding, easy operation, high drilling efficiency and low labor intensity.
, Equipped with enough instruments, which is conducive to grasping the situation in the hole, less joysticks, more reasonable layout, flexible and reliable operation.
7. The double-plate normally closed friction clutch is adopted, which is flexible to open and close, and is easy to operate and adjust.
8. Equipped with front and rear moving oil cylinders, the gyrator moves 465mm backwards, which brings a lot of convenience to the drilling tool.
9. The structure is compact, small in size, light in weight, easy to disassemble, easy to disassemble and carry, and can be used for drilling in hills or mountainous areas.
