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.
The rotation unit has running steadily and transmission accurately, it has more advantages in the deep drilling.
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.
Rig has high lifting speed, which can improve the rig’s efficiency and decrease the auxiliary time.
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.
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.
Rig has the clamp machine and the unscrew machine, so it is convenient for unscrew rod and decrease the work intensity.
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.
The hydraulic driving head can move away the drilling hole.

The YDL-2B crawler drill is a full hydraulic top drive drilling rig mainly utilized for diamond bit drilling and carbide bit drilling. It is also suitable for diamond drilling with wire-line coring techniques.
The drilling depth capacities vary based on the pipe size: up to 1000 meters for BQ (Ф56mm), 600 meters for NQ (Ф71mm), 400 meters for HQ (Ф89mm), and 200 meters for PQ (Ф114mm).
The rotation unit features advanced French engineering. It is driven by dual hydraulic motors with mechanical speed adjustment, providing a broad speed range and high torque at low speeds to ensure stable and precise deep drilling.
The hydraulic system employs plunger-type designs for both the rotary motor and the main pump. This French-engineered configuration ensures safer, more reliable operation during high-intensity drilling tasks.
It features a BW-250 model three-cylinder reciprocating piston mud pump and is powered by a 6BTA5.9-C180 diesel engine rated at 132KW / 2200rpm.
