II. Core Performance and Advantages

High efficiency and energy saving: By adopting the SANY SYMC controller + EP power distribution system, the soil construction efficiency is improved by about 20%, and the comprehensive fuel consumption is reduced by 10%–15%. The compound action is smooth, and the soil throwing speed is fast.
Multi-method adaptability: Supports rotary drilling, long spiral (CFA), secant piles, deep mixing, and other construction methods; low clearance mode allows operation under bridges/indoors; drill rod visualization + floating pre-tightening protect the drilling tools and extend the lifespan of steel wire ropes.
Intelligence and Safety: High-definition intelligent touch screen for real-time monitoring of parameters; centralized automatic lubrication; equipped with overload protection, turntable locking, tilt alarm, and remote diagnosis to reduce downtime.
Application scenarios: bridge pile foundations, high-rise building foundations, municipal roads, reservoir dam seepage prevention walls, ports and docks, etc.; it has good penetrability to clay, sand layers, pebbles, and moderately weathered rock formations.
