Product Description

Specification

Dminingwell MW280 crawler water well drilling rig

MW280 crawler water well drilling rig is a powerful, fully hydraulic drilling machine designed for efficient water and air drilling, featuring a heavy-duty excavator chassis, high-torque rotary system, and flexible dual-system configuration for complex ground conditions.
1. Powered by a 75 kW Yuchai turbocharged diesel engine with full hydraulic control for walking, rotation, feeding, lifting, and outriggers.
2. Patented composite mast with 6.6 m stroke, double-cylinder lifting, and cylinder protection blocks for strong and safe operation.
3. Professional steel excavator crawler chassis with reducer-equipped travel motors for durability, stability, and low ground damage.
4. Parallel gearbox with independent oil pumps and optimized hydraulic system for sufficient power, easy maintenance, and low operating cost.
5. Supports dual drilling systems (air compressor or mud pump), high-speed rotary up to 150–160 rpm, hydraulic outriggers, and precision wellhead positioning for efficient and accurate drilling.
 
Customization available. MW series covers drilling depths from 180 m to 1000 m.
