Structural reinforcement XCMG Xr280 Rotary Drilling Rig

Strong torque and industry-leading rock penetration ability

300kN · m ultra large torque+260kN full stroke pressurization, suitable for hard rock formations such as weathered sandstone, granite, limestone, etc., with a rock penetration efficiency 15% -20% higher than similar models.
Wide speed range of 6-27rpm, fast soil throwing for soft soil and low-speed high torque cutting for hard rock, with strong adaptability to geological formations.
The power head is intelligent and adaptive, automatically matching the resistance of the formation, reducing drilling blockage and jamming, and the verticality of the borehole is ≤ 1 ‰.

Sturdy structure, full of stability and reliability

Special H-type hydraulic telescopic track chassis+large diameter slewing support: The track has a deployed width of 4800mm, a low grounding ratio, strong anti overturning ability, and first-class stability in deep hole and hard rock construction.
Double arm parallelogram amplitude mechanism: optimized hinge points, large support range, strong rigidity of drilling mast, small shaking, high drilling accuracy.
Segmented thickened box type drilling mast+three sided guide rail: anti torsion, anti impact, long-term heavy load without deformation.
Single row rope main/auxiliary winch: The lifespan of the steel wire rope is increased by 2-4 times, and the annual maintenance cost is significantly reduced.
Centralized automatic lubrication+lubrication free hinge point: reduces manual maintenance and increases equipment attendance.

Intelligent control, precise, safe and easy to use

PLC+CAN bus+10 inch touch screen: real-time display of hole depth, verticality, fuel consumption, fault codes, one click vertical adjustment, automatic hole alignment, intelligent drilling.
Multiple safety protections: power head torque limit, automatic pressure limit, overload prevention, anti overturning, 360 ° panoramic monitoring, ensuring safer construction.
Remote monitoring and diagnosis: GPS positioning, labor/fuel consumption statistics, remote troubleshooting, efficient fleet management.

Multi method adaptation, one machine with multiple uses and wide coverage

Support rotary excavation, oil cylinder pressurization, winch pressurization, long casing, pipe rolling machine CFA、 Dual power head, pneumatic down the hole hammer and other full construction methods, easy to switch.
Special design for long casing: 6m pressure stroke, smooth lowering of casing, suitable for complex formations such as backfill soil, quicksand, gravel, etc.
Optional torque multiplier, with a casing drive torque of up to 450kN · m, providing stronger construction capability for hard layer casing.
