2020 Sany SR235 Drilling Rig

The SANY SR235 rotary drilling rig is a versatile and powerful piling machine developed for medium to large-scale deep foundation projects. Designed to balance performance, efficiency, and reliability, the SR235 is widely used in bored pile construction for bridges, commercial buildings, residential high-rises, and municipal infrastructure works.

Equipped with a high-performance diesel engine rated at approximately 257 kW, the SR235 provides strong and stable power output while maintaining optimized fuel efficiency. The machine delivers a maximum output torque of around 235 kN·m, enabling effective drilling in clay, sand, gravel, and moderately weathered rock formations. It offers a maximum drilling diameter of up to 2000 mm and a maximum drilling depth of up to 68 m (friction Kelly bar), meeting the requirements of most urban and infrastructure foundation projects.

The SR235 features a robust mast structure and reinforced crawler undercarriage, ensuring stability during deep drilling operations. Its advanced hydraulic system allows smooth multi-function control, while the intelligent monitoring interface provides real-time operational data to improve accuracy and jobsite safety.

Compatible with both friction and interlocking Kelly bars, the SR235 can be configured according to different geological conditions, offering flexibility and high construction efficiency for international contractors seeking dependable foundation equipment.
