Low failure rate SANY Sr405 Rotary drilling rig

Super strong rock penetration and deep pile capability, preferred for hard rock/100 meter piles

405kN · m high torque+5-25rpm wide speed regulation: suitable for moderately weathered to slightly weathered granite, limestone, sandstone, with a rock penetration efficiency 20% -30% higher than domestic models of the same level, and a significant increase in daily pore formation in hard rock.
The sixth generation 580 drill rod+integral pressure platform: material upgrade, strengthened ring design, stronger resistance to torsion and impact, increased pressure by 15%, increased rock penetration capacity by 25%, 5-section machine lock rod hard rock drilling depth can reach 88m.
Full stroke pressurization+large stroke oil cylinder: With a pressurization stroke of 6m, the construction of long casing/casing is more relaxed, and it has significant advantages in dealing with easily collapsed formations such as quicksand and backfill soil.
Hundred meter deep pile capacity: The maximum friction rod is 106m, which meets the needs of ultra deep piles such as cross sea bridges, super high-rise buildings, and high-speed railway bridges.

Extremely stable structure, reliable for heavy-duty continuous construction

131t ultra heavy rotary excavator special chassis: 800mm wide tracks, expandable track spacing, low center of gravity+high ground pressure, no overturning during soft foundation/steep slope construction, and no downtime for 2 consecutive months. Case three.
Box type drilling mast+double boom amplitude: anti torsion and anti alternating load, no deformation during deep hole construction, hole verticality ≤ 1 ‰, smooth lowering of steel cage.
Parallelograms mechanism: flexible transition, fast positioning in restricted areas, transportation height ≤ 3.75m, no need to dismantle masts, high transition efficiency.
Structural component lifespan>20000 hours: Key parts are reinforced, with low failure rate and attendance rate ≥ 95%.

Intelligent control and efficient energy saving, first-class human-machine experience

Intelligent cockpit+high-definition touch screen: low-noise constant temperature, 6 intelligent functions (automatic sag adjustment, parameter memory, fault diagnosis, pressure table display, etc.), reducing pilot strength by 50%.
Yiweixun APP remote management: GPS positioning, labor/fuel consumption statistics, remote diagnosis, one click call service, efficient fleet management.
Load sensing hydraulic+ECO mode: on-demand power distribution, comprehensive fuel consumption 10% -15% lower than industry peers, annual fuel savings of 60000-120000 yuan.
Centralized lubrication system: time-saving and labor-saving maintenance, reducing maintenance costs by 20%.

Multi method full coverage, one machine for multiple uses, reducing costs and increasing efficiency

Basic construction method: dual mode of oil cylinder/winch pressurization, rapid construction in conventional geological formations.
Extended construction method: supports long casing, pipe rolling machine CFA、 Dual power head, suitable for complex formations such as karst, gravel, and deep soft soil.
Strong casing construction: 13m ultra long winch pressure stroke, long casing can be lowered in one go, resulting in more stable pile quality.
Flexible selection of drill rods: Friction resistance/machine lock/self-locking drill rods are optional, suitable for different hole depths and geology.
