Application: It is mainly used for diamond bit drilling and carbide bit drilling of solid bed. It also can be uses in exploring drilling and base or pile hole drilling and the small water well drilling.
Ò»£®Main Features£º |
1£®Rotation unit(hydraulic driving rotation head) adopted the France technique. It was drive by dual hydraulic motor and changed speed .by the mechanical style. |
| 2£®The rotation unit has the more stiffness spindle, transmission accurately and running steadily more advantages in the deep drilling. |
3£®The feeding and the lifting system use the single hydraulic cylinder driving the chain. It has the long feeding distance character, easy to the long rock core drilling process. |
| 4£®Rig has the high lifting speed, it can decrease the auxiliary time and improve the rig¡¯s efficiency. |
| 5£®the V style orbit in the mast can sure the enough rigidity between the top hydraulic head and the mast and give the stability at the high rotation speed |
6£®The hydraulic driving head can move away the drilling hole, accompany with the clamp machine system and the unscrew machine system, so it bring the convenient for the rock core drilling. |
7£®The main winch adopted the import product, work stability and brake reliability. |
8£®The winch for lifting the rock core has the 205m/min speed when drum empty. |
| 9£®Rig has the clamp machine and the unscrew machine, so it is convenient for unscrew rob and decrease the work intensity. |
10.The hydraulic system is reliable, the mud pump control by the hydraulic valve. All kind of the handle is concentrate at the control set, so it is convenient to solve the accident at the down of drilling hole |
