High-speed hole formation SANY Sr280 Rotary Drill Rig

Efficient Rock Penetration and Working Condition Adaptability:

The power head torque reaches 280kN/m, supporting three modes: standard, low-speed high-torque, and high-speed low-torque. Combined with 230kN pressing force and 300kN pulling force, the rock penetration efficiency is better than that of similar models; torque, rotation speed, and pressing force can be automatically matched, and the rock penetration adaptive technology improves the construction efficiency in complex formations.

Structural Stability and Reliable Shock Absorption:

The truss-type anti-vibration mast is optimized for frequency resonance, with strong bending resistance, compression resistance, and shock absorption capabilities; the enhanced buffer device of the power head increases the shock absorption capacity by 4.3 times, and the service life of the motor and reducer is increased by 3 times, reducing maintenance costs.

Chassis and Hydraulic System:

The C-A-T 336D chassis has strong bearing capacity and high stability, with a traction force of 510kN and a climbing gradient of 35%; modular hydraulic arrangement, multi-rate pulling of the main winch, with bottom contact protection and priority control, suitable for complex constructions such as long casing.
Intelligent and Safety Configuration: The drill pipe visualization system displays the position of the pressure platform in real-time to avoid damage; the centralized automatic lubrication system reduces manual maintenance; GPS remote monitoring and fault early warning improve equipment management efficiency.

Multifunctional Construction Method Expansion:

It can switch between CFA construction method and rotary drilling construction method, and optional pipe twisting machine; full hydraulic soil cleaner, bottom casing device, etc., reduce labor costs and ensure drilling accuracy and verticality.

Second-Hand Residual Value and Maintenance Friendliness:

The Ca-terpi-llar chassis and core components have high durability, with a large number of second-hand markets, low failure rates, large maintenance space, easy maintenance, and significant advantages in long-term operating costs.
