Advantages of Power Drilling

285kN · m rated high torque, strong adaptability to geological formations
Equipped with a high-power power head as standard, the torque and speed can be infinitely adjusted, making soft soil drilling light and easy, and the ability to break pebbles and weathered rock layers is sufficient; The maximum pile diameter is 2200mm, the deepest friction rod is 94m, and the deepest machine lock rod is 61m. Small and medium-sized pile foundations are fully covered
Full stroke long-term pressurization system
17.1m ultra long pressurization stroke, fast lifting and pressurization speed, long casing and deep hole construction are not easy to suck up and collapse holes, and the advantages of backfill soil and river beach soft formation construction are prominent
Reliable imported powertrain
Equipped with Isuzu high-power diesel engine, with abundant power reserve and low idle fuel consumption; Power matching hydraulic system, smooth composite action, strong continuity in soil drilling and lifting, and higher daily pile forming quantity

Efficient and fuel-efficient, with lower operating costs

Intelligent power zoning control
The system distributes power in real-time based on drilling load, reducing power under no-load conditions and outputting at full load conditions. Compared to other models in the same class, the comprehensive fuel consumption is 10% to 15% lower, resulting in significant savings in long-term construction fuel expenses
Step type main winch drum
Single layer arrangement and winding of steel wire rope, without compression or grinding damage, increases the service life of steel wire rope by 35%, significantly reducing the frequency of consumable replacement; The winch has a faster rope lifting speed and higher hole efficiency
The sixth generation integral locking drill pipe
High strength thickened pipe wall+integral locking structure, strong resistance to torsion and deformation, reliable locking without slipping, increased drilling efficiency by 10%, and drill pipe failure rate far lower than old-fashioned drill pipes
