Reliable Power SANY SR280 Rotary Drilling Rig

Strong rock penetration capability, suitable for complex strata

Rated output torque: 280kN・m, dual-motor dual-reduction power head, capable of stably drilling through medium weathered rock, limestone, and karst strata; supports various drill tools such as core barrel drilling and sand bucket retrieval, with strong versatility for building, municipal, and bridge pile foundations.

Upgraded damping structure with high durability

The power head features enhanced buffer reinforcement, with shock absorption capability improved by 4.3 times, significantly extending the lifespan of the motor and reducer. The mast and luffing structure have been optimized for increased stiffness, superior impact and sway resistance, better hole verticality, and reduced fatigue damage to structural components during hard rock construction.

The hydraulic and electric control system is stable, ensuring smooth operation

The electric proportional pressurization system features stepless adjustable pressure; smooth compound actions with rapid response in rotation, lifting, lowering, and travel; equipped with primary winch floatation, anti-ground contact protection, and adaptive torque-speed adjustment for soil layers, ensuring fuel efficiency and excellent controllability.
