Full Hydraulic Driving Drilling Equipment SDC-2A Used For Diamond Bit Drilling Mobile Drilling Rigs

Mobile Drilling Rigs Full Hydraulic Driving Drilling Equipment SDC-2A Used For Diamond Bit Drilling

SDC-2A Mobile Drill

SDC2A mobile drill is one kind of full hydraulic driving drilling equipment installed on the classic of EQ1141NBJ diesel truck.

1. Application range
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.
2. Main features
(1)Rotation unit(hydraulic drive head)adopted the international advanced 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 distance characters. It is easy for 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.
(7)Rig has the clamp machine system and the unscrew machine system, so it bring the convenient for the rock core drilling.
(8)The hydraulic system adopted the France technique; the hydraulic system has the high reliability.
(9)The mud pumps control by the hydraulic valve. All kind of the handle is concentrate at the control set, so it is convenient to solve the incident at the down of drilling hole.
