Product Description

Specification

Dminingwell MW300 crawler water well drilling rig

MW300 crawler water well drilling rig is a high-efficiency, fully hydraulic drilling machine designed for medium to deep water well projects. With strong rotary torque and dual drilling methods (mud and DTH air drilling), it delivers reliable performance in complex geological conditions.
1. 300 m drilling depth with 140–325 mm bore diameter for industrial, agricultural, and geological wells.
2. High-torque rotary system delivering 5700–7500 N·m with stable 40–70 rpm operation.
3. Powerful Yuchai diesel engine (85 kW) with 18T lifting force for deep-hole drilling.
4. Supports mud drilling in soft formations and DTH air drilling in rock with high penetration efficiency (15–35 m/h).
5. Heavy-duty crawler chassis with full hydraulic control, auxiliary winches, and easy maintenance for long-term operation.
 
Customization available. MW series covers drilling depths from 180 m to 1000 m.
