SKW400 Water Borehole Drilling Rig
- Hole diameter :140–325
- Drilling depth: 400mm
> Reliable 400m Deep Water Borehole Well Drilling Solution
> The 400m water well drilling rig is a high-performance machine specifically engineered for medium-to-deep borehole projects. With a robust hydraulic system and a maximum drilling depth of 400 meters, it is widely used in farm irrigation, industrial water supply, and geothermal heating installations.


> Core Advantages:
> * Powerful Lifting Capacity: Designed to handle heavy drill strings and casing pipe with ease, ensuring safe operation at maximum depth.
> * High Torque Power Head: Features a top-drive hydraulic head that provides consistent rotation for fast penetration in rock and soil layers.
> * Advanced Mud Circulation: Perfectly compatible with BW-450 or BW-600 mud pumps for efficient debris removal.
> * Reinforced Chassis: The wide steel crawler tracks provide excellent stability and balance even on soft or uneven ground.
