Reinforcement key structures High SANY Sr220 Rotary Drill Rig

Strong power, efficient drilling (benchmark in the same level)

250kW high-power engine: the mainstream highest power configuration in the same class, with no attenuation during heavy-duty continuous operation, and a drilling efficiency in hard rock that is 10% -15% higher than the same torque model.
Load sensitive hydraulic+power head adaptive: intelligent matching of torque and pressure, 7-26rpm wide speed covering clay for rapid soil throwing, stable cutting of pebbles/mudstone, avoiding boring and idling.
240kN high lifting force+70m/min high-speed winch: Strong ability to escape from difficulties during buried and stuck drilling, fast lifting and lowering speed, shortened single pile cycle time, and 4-6 piles per day (Φ 800-1200mm, 20-30m).
Actual performance: In medium hard rock layers such as granite, the drilling efficiency is improved by about 25% compared to similar models, and a single pile can save more than 30 minutes, resulting in a significant increase in annual revenue.

Sturdy structure, stable and reliable (high attendance rate)

Heavy duty chassis+wide track design: The track deployment width is 4300mm, the grounding ratio is low, the anti overturning ability is strong, the mast shaking is small during construction, and the hole verticality accuracy is high (≤ 1 ‰).
High rigidity drilling mast+segmented thickening structure: optimized through finite element analysis, robot welding+100% non-destructive testing, long-term high-strength construction is not easy to deform, suitable for deep holes and complex formations.
Customization of core components: gearboxes, slewing bearings, and hydraulic components jointly designed with internationally renowned manufacturers, with high compatibility, few failures, and long maintenance cycles.
Centralized automatic lubrication: Key hinge points are automatically refilled at regular intervals, reducing manual maintenance, lowering early wear, and extending equipment lifespan.

Intelligent control, safe and easy to use (lowering the threshold)

S-ADMS intelligent system: 10 inch high-definition touch screen, real-time monitoring of hole depth, verticality, fuel consumption, fault codes, supports one click vertical adjustment, intelligent drilling, easy for beginners to operate.
Drill pipe visualization+anti misoperation protection: Real time display of machine lock rod/friction rod position to prevent pressure overload and drill pipe damage, improving construction safety.
360 ° panoramic monitoring+safety warning: blind spot visibility, collision and overturning prevention, safer construction at night; AI fault diagnosis provides early warning of potential problems and reduces downtime.
Remote management: Supports the Yiweixun APP to view device location, working hours, and fuel consumption in real-time, making fleet management efficient and convenient.
