Fast pulling‑out speed SANY SR220 Rotary Drill Rig

Power and drilling capability

Rated torque 220kN・m, maximum drilling depth with friction rod 64m, machine locking rod 47m, maximum pile diameter 2.3m, suitable for housing construction, municipal projects, bridges, and ordinary highway piles
The SR220R rock penetration version features optimized torque and pressurization systems, capable of handling strongly and moderately weathered rock layers to meet foundation penetration requirements
The main winch features a floating function, eliminating the need to continuously raise the winch when lowering the drill pipe, thereby saving effort and fuel while preventing wire rope tangling

Hydraulics and Energy Efficiency

Load-sensitive hydraulic system, on-demand flow output, low fuel consumption under light-load conditions, superior economy in the same class
Multi-mode options: Drilling, Fast, and Energy-saving modes, offering significant cost advantages for long-term urban construction
CAN Bus Whole Machine Monitoring, Real-time Data Acquisition for Engine, Hydraulic, and Winch Status, with Intuitive Fault Alarms

Structurally reliable and durable

The large box-type mast and high-strength welded chassis provide resistance to torsion and bending, reducing the likelihood of cracking. The stress-concentrated areas of the drill pipe are reinforced for extended service life
The tracked chassis has a reasonable ground pressure, ensuring good off-road capability on soft terrain. The machine’s weight is well-balanced, reducing the risk of getting stuck
