Stable hole-forming quality XCMG XR280D Rotary Drilling Rig
Description
Detailed description
Description
Strong torque, stable rock penetration, deep hole strength: 28 ton “rock penetrating small steel cannon”
280kN · m+210kN compression: easy to dry strongly/moderately weathered rocks, pebble layers, and isolated stones, with a rock penetration efficiency 30% higher than 220, more flexible and cost-effective than 360.
88m ultra deep hole+2.5m large diameter: The deep hole of the friction rod has good verticality and is suitable for high-rise buildings, subways, and wind power foundations; 6m long stroke pressurization, long casing/full casing without rod jamming or hole collapse.
Power head rock entry mode: automatically matches torque/speed, does not hold the machine or shake the rod in hard rocks, and has stable drilling quality.
Single row rope+Cummins: fuel-efficient, durable, and much more fuel-efficient over time
Rear single row rope main winch: The steel wire rope has no compression or twisting, doubling its lifespan and reducing downtime and consumables costs (saving more than 30% compared to double row ropes).
298kW Cummins+load sensing hydraulic: sufficient power, fast response, smooth composite action; The comprehensive fuel consumption is 10% -15% lower than that of the same level, and the annual fuel savings are 30000-60000 yuan; Idling automatically reduces speed and saves idle time.
Large diameter slewing bearing+88t heavy body: stable operation, strong anti vibration, no shaking of hard rocks, no drifting of deep holes, reducing rework.
Intelligent and stable, easy to operate and handle: with few malfunctions, even beginners can learn
XCMG self-developed CAN bus+PLC electronic control: 3ms response, high-definition screen real-time display of hole depth/verticality/torque; Anti jamming pole, anti misoperation, overload/overturning/limit/anti fall full protection.
Mast automatic sag adjustment+depth self recording: one click calibration, accurate data, reducing manual errors; The main winch is equipped with an infrared camera, allowing the driver’s cab to directly view the steel wire rope, ensuring safety and peace of mind.
Parallel quadrilateral variable amplitude+box shaped mast: strong rigidity, good torsional resistance, high drilling accuracy; 360 ° rotary slag removal, with few dead corners and high efficiency.
