Product Overview
What is Hydraulic Crawler Water Well Drilling Rig?
The Dminingwell WM350 Hydraulic Crawler Water Well Drilling Rig is a heavy-duty and multi-functional deep borehole drilling machine designed for groundwater extraction, irrigation wells, industrial water supply, and geothermal heating projects.
Driven by a powerful hydraulic system and mounted on a robust crawler chassis, the WM350 offers exceptional mobility, stability, and drilling performance in medium–hard and hard rock formations.
For users seeking smaller drilling equipment for light-duty environments, please refer to 【Small crawler water well rig 】.
If your project requires DTH drilling knowledge, see 【DTH Hammer Selection Guide 】.
When operating in loose formations, the optional 【ODEX/Eccentric Casing System 】 provides excellent borehole protection.
Powered by a reliable 92 kW Yuchai engine, the WM350 delivers a high hydraulic output and large rotary torque, making it ideal for demanding drilling operations.
To support the rig, Dminingwell supplies matched pneumatic equipment including 【Portable Screw Air Compressors 】, 【Mobile Screw Air Compressors 】, and high-pressure units suitable for DTH drilling .
With a 6.6m one-time feed stroke, long drill pipe options, and 15–35 m/h penetration efficiency, the WM350 is built for high productivity.
