Strong torque SANY SR250 Rotary Drilling Rig

Strong torque, efficient rock penetration

250kN · m high torque, about 6% higher than SR235, more stable and faster drilling in hard rock and gravel layers.
208kN pressure combined with high torque effectively reduces drill jumping and hole deviation, significantly improving rock penetration efficiency.
5.3m pressurization stroke, meeting the requirements of complex construction methods such as long casing and full casing.

Intelligent electronic control, precise and stable

SYMC intelligent control system, 10 inch touch screen, real-time parameter monitoring, one click setting.
Automatic monitoring and correction of verticality, high drilling accuracy, and effective control of pile quality.
The hydraulic load sensitive system has fast response and smooth composite action, reducing fuel consumption by about 5-10%.

Reliable structure, durable and worry free

The fifth generation integral power head has high welding strength, good sealing, impact resistance, and is not easy to crack.
The reinforced mast and variable amplitude mechanism have a lifespan of over 20000 hours for key structural components, making them suitable for high-intensity construction.
International first-line hydraulic components (Kawasaki, Rexroth), single row rope main winch, long service life of steel wire rope, low maintenance cost.
Centralized automatic lubrication+remote fault diagnosis, convenient maintenance, and reduced downtime.
