Key Features and Performance
- Dual Rotary Technology: Features a unique lower rotary drive that advances steel casing through unconsolidated overburden like sand, gravel, glacial till, and boulders.
- Enhanced Torque: The DR24HD’s heavy-duty gear-driven lower drive generates two and a half times the torque of the standard DR-24 model, reaching up to 2,500,000 in-lbs.
- Superior Pullback: Equipped with a heavy-duty mast and larger hoist cylinders, it offers an increased pullback capacity of 118,000 lbs for the lower drive and 80,000 lbs for the top drive.
- Versatile Drilling: Supports various methods including mud, air, reverse circulation, and flooded reverse circulation. It can use conventional tools such as down-the-hole hammers, roller cones, or drag bits.
- Precision and Quality: The lower drive’s casing rotation results in exceptionally straight holes, minimizing stress on casing welds and simplifying the installation of screens and pumps.
