Efficient SANY SR405R Rotary Drilling Rig

405kN · m+6th generation drill pipe: King of hard rock, full rock penetration efficiency

Ultra high torque+strong pressure: 405kN · m torque+340kN pressure, easy to dry intact granite, strongly/moderately weathered rock, ultra thick pebble layer, and solitary rock, with a rock penetration capacity increased by 25%+compared to 365, fast drilling of hard rock, and no machine holding.
The sixth generation 580 drill pipe: integrated pressure platform+material upgrade+strengthening ring, with a 25% increase in strength, strong impact resistance, anti torsion and crack prevention; The hard rock depth of the 5-section machine lock rod reaches 88m, and the verticality of the 106m deep hole of the friction rod is stable.
Full casing/casing king: 340kN pressure+400kN main winch, suitable for full casing, casing follow-up, CFA long spiral, no collapse or shrinkage of holes in quicksand/groundwater/soft rock.

377kW Cummins+high flow hydraulic: sufficient power, compound smoothness, fuel saving

Cummins high horsepower: 377kW, abundant power, fast response, stable in high altitude/high temperature/low temperature; Load sensing hydraulic+large displacement main pump, with smooth composite action, no jamming, and high efficiency.
Intelligent fuel saving: Big data optimized fuel consumption, 10% -15% lower than peers, saving 60000-120000 yuan annually; Idle automatic speed reduction, intelligent load matching, powerful heavy work, and energy-saving light work.
Single row rope main winch: With a diameter of 36mm thick rope and no compression or twisting, the lifespan is doubled, reducing downtime and material costs during rope replacement.

131t heavy machine+box type mast: as stable as a rock, deep hole does not float

Heavy duty specialized chassis: 131t heavy weight, low center of gravity, 5.2m wide tracks, no shaking on hard rocks, no drifting in deep holes, extremely strong resistance to overturning, high drilling accuracy, and minimal rework.
Box type mast+double boom: strong rigidity, good resistance to torsion, resistance to alternating loads, and no deformation during long-term construction; 360 ° rotary slag removal, with few dead corners and high efficiency.
Stable under all operating conditions: Large holes/deep holes/hard rocks/full casing are stable, and continuous operation for 2 months without stopping, with full reliability.
