Application Range

YDL-2B crawler drill is full hydraulic top drive drilling rig, which is mainly used for diamond bit drilling and carbide bit drilling. It also can be used in diamond drilling with wire-line coring technique.

Main Features

(1) Rotation unit adopted the France technique. It was drive by dual hydraulic motors and changed speed by the mechanical style. It has the wide range speeds and high torque at the low speed.

(2) The rotation unit has running steadily and transmission accurately, it has more advantages in the deep drilling.

(3) The feeding and the lifting system use the single hydraulic cylinder driving the chain, which has long feeding distance and giving the convenient for the drilling.

(4) Rig has high lifting speed, which can improve the rig’s efficiency and decrease the auxiliary time.

(5) 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 the drilling hole.

(6) The V style orbit in the mast cans sure the enough rigidity between the top hydraulic head and the mast , and gives the stability at the high rotation speed.

(7) Rig has the clamp machine and the unscrew machine, so it is convenient for unscrew rod and decrease the work intensity.

(8) For the hydraulic system to running more safely and reliably, it adopted the France technique, and the rotary motor and main pump both use the plunger type.

(9) The hydraulic driving head can move away the drilling hole.
