About HY150S Hydraulic Water Well Drilling Machine
The HY150S mini water well drilling rig is an independently‑developed product of our company. It supports both pneumatic DTH drilling and mud pump rotary drilling, enabling fast penetration in hard rock formations. In addition, it comes with four heavy‑duty hydraulic outriggers, making this water well drilling machine extremely easy to transport.
Furthermore, the rig adopts the latest advanced hydraulic technology, delivering low fuel consumption, high rotary torque, and user‑friendly operation. It is widely applied in various projects, including deep water well drilling, agricultural irrigation well drilling, geothermal well drilling, exploration borehole drilling, and miniature pile driving. Thanks to its strong performance, the HY150S reaches a maximum drilling depth of 150 meters.
Besides, we equip this unit with a robust 42 kW Yunnei diesel engine that provides steady and sufficient power output. Its rotary head generates a maximum torque of 4,600 N·m and offers a 12‑ton lifting capacity. Despite its compact footprint, this small drilling rig delivers outstanding drilling capacity. It uses 2‑meter drill rods for simple and fast rod loading and unloading.
Moreover, we manufacture this compact drilling rig with premium raw materials. It features a sleek, compact structure, high working efficiency, low failure rate, excellent cost‑effectiveness and a long service life. Our drilling rigs have been fully verified by market practice, and they earn consistent positive feedback from global customers.
