تتميز حفارة الحفر الدوراني SANY SR360 بكفاءة عالية في البئر الواحد

Strong construction capability and outstanding rock penetration performance

The rated torque is 360kN · m, the maximum pile diameter is 2.5m, the maximum drilling depth of the friction rod is 100m, and the machine lock rod is 65m. It can cope with large-diameter deep pile foundations for bridges, high-speed railways, and high-rise buildings. Equipped with an adaptive power head for rock insertion, the multi gear torque and speed are automatically matched, resulting in higher cutting efficiency for hard rock formations such as sandstone and mudstone. The 50-80MPa rock formation can be stably embedded for rock construction

High stability of the whole machine

Special heavy-duty chassis, track width of 4840mm, total weight of 120 tons, low center of gravity; The large triangular amplitude truss mast has strong bending and torsion resistance, and is not easy to shake or tilt during deep hole and hard rock operations. The anti vibration structure reduces rock impact and has a long fatigue life for structural components.

Power hydraulic system, efficient and energy-saving

Equipped with Isuzu high-power engine and Kawasaki negative control hydraulic system, flow is distributed according to demand; The main winch merges and lifts quickly, with a maximum lifting speed of 75m/min and smooth compound movements. Intelligent load control, with lower fuel consumption compared to similar models, and significant advantages in long-term construction and operation costs.
