High verticality of drilled hole SANY SR200 Rotary Drilling Rig

Powerful and efficient construction

Kawasaki Negative Control Hydraulic System: Unique in its class, with precise pump valve matching, fast response, and low loss.
Main winch rapid merging: lifting speed of 72m/min, hole forming efficiency is about 10% higher than competitors.
High torque+wide rotation speed: 7-30rpm, suitable for efficient drilling in soft soil, clay, sand layers, and moderately weathered rocks.

Low fuel consumption and low operating costs

Intelligent power matching between engine and hydraulic system, on-demand output, with fuel consumption 5% -10% lower than the same level.
Isuzu engines are sturdy and durable, with long maintenance cycles and good fuel adaptability.

Sturdy structure and high reliability

International customization of key components: Kawasaki pump valves, Rexroth/Italian motors, German reducers, highly matched.
Finite element+fatigue analysis: optimization of key structures such as mast, drill pipe, and chassis, robot welding, and 100% non-destructive testing.
Enhanced chassis: SY310RC dedicated rotary excavator chassis, 700mm wide tracks, low ground pressure ratio, strong adaptability to the site.

Comfortable operation and precise control

Large space cab: suspended seats, low noise and dust-proof, low handle force, easy operation.
Intelligent monitoring system: large screen display parameters, fault self diagnosis, real-time warning, reducing misoperation.
Mast automatic verticality adjustment: automatically corrected within a tilt range of ± 3 °, with high hole verticality and stable quality.
