Description – Product Strength:
Utilizes Rexroth (Germany) automatic control system with load-sensing, increasing thrust force by 15%–20%, saving ~50% energy, and reducing heat.
Equipped with Cummins engine for high efficiency, low fuel consumption, and robust performance.
High-power Cummins engine enhances performance.
Auxiliary booster increases traction to 900 kN for large-diameter safety.
Four-layer sliding plunger mud pump structure improves suction angle and prevents separation.
Reversible electromagnetic vibrator enables efficient drill rod loading/unloading and reduces labor.
Comes with friction drums: φ89 × 3000 mm, φ114 × 3000 mm, φ127 × 3000 mm, suitable for medium-duty high-efficiency construction.
Key hydraulic components from world-leading brands ensure high reliability.
Optimized electrical system with low failure rate and easy maintenance.
Rack-and-pinion propulsion system ensures efficiency, long life, and easy service.
Patterned steel crawler tracks provide strong terrain adaptability.
“Casing-within-casing” drilling technology supports hard rock and high-efficiency operations.
