Fast hole forming XCMG XR220D Rotary Drilling Rig

Power and hydraulic system: fuel-efficient and powerful, suitable for complex geological formations

Reliable and durable power
Equipped with Cummins QSL9 electronically controlled turbocharged engine, with a rated power of 242kW and sufficient power reserve; Electronic control speed regulation optimizes fuel consumption, reducing fuel consumption by 12% to 15% in the same class, suitable for long-term continuous pile driving; Compliant with Euro III emissions, both domestic and overseas exports can be registered in compliance
Energy saving and efficient hydraulic system
Adopting a dual control hydraulic architecture of positive flow and maximum power, flow is distributed according to demand, significantly reducing energy consumption under no-load and drilling conditions; Paired with Kawasaki imported main pump and motor, it has fast response, low failure rate, and balanced drilling efficiency in soft and hard soil layers

Chassis and overall stability: Strong resistance to overturning, convenient transition

Specialized telescopic crawler chassis for rotary excavation
The track gauge can be adjusted to 3500-4400mm: during construction, the wide track is deployed, with a grounding pressure of only 90kPa, and the muddy and soft ground does not sink; After folding the tracks, the overall width of the vehicle narrows, and the flatbed truck can be transported directly without dismantling large parts, saving time and money for short distance transfers.
Large diameter slewing bearing+high-strength drilling mast
Thickened large gear ring rotary bearings have strong anti torsion and anti overturning capabilities; The box type integrated drilling mast has sufficient rigidity, high drilling verticality accuracy, and is less prone to deviation when drilling deep or large holes; The parallelogram amplitude changing mechanism has a wide range of operation coverage and strong adaptability to the site.

Winch and drilling system: longer lifespan, precise measurement

Single row rope main winch
Single layer winding structure thoroughly improves the compression wear of steel wire rope caused by multi-layer winding, and doubles the service life of steel wire rope; The winch is equipped with a drilling depth sensing device, which provides accurate distance measurement for single-layer winding, minimal error in hole depth data, and uniform hole forming standards.
Standard multifunctional homework configuration
The original factory comes with a winch pressurization and casing drive device, which can directly perform full casing wall protection construction to cope with quicksand and collapse formations; Multiple specifications of drill rods can be matched with friction rods and machine lock rods, with a maximum drilling diameter of 2.2-2.5m and a maximum depth of 88m. Construction can be carried out on clay, gravel, and moderately weathered rock layers.
Easy maintenance of power head
Detachable drive key design, parts can be replaced separately after wear and tear, without the need to disassemble the power head as a whole, greatly reducing maintenance time
