Product Description
Discover the DTH-150 Water Well Drilling Rig—your professional-grade choice for versatile, efficient, and deep borehole drilling. Powered by a robust 120 HP deck engine, the DTH-150 delivers up to 4000 Nm of rotary head torque and variable speeds from 0–100 rpm, enabling fast and accurate drilling in diameters ranging from 115–165 mm. Ideal for DTH (Down-The-Hole) and mud rotary drilling methods, this rig effortlessly adapts to rock, clay, and mixed formations with both air and water flushing mediums.
Mounted on a two-wheel trolley, truck (4×2), crawler, or skid, the DTH-150 optimizes site mobility for quick setup and efficient relocation. Hydraulic systems provide a smooth rod changing process with automated breakout wrench and a generous 300-liter tank for continuous operation. The rig supports air compressors up to 600 CFM/200 PSI, mounted on separate trolley/truck, and optionally features hammer opener, GPS monitoring, and fuel tracking—guaranteeing both safety and productivity.
