جهاز حفر دوار عالي العزم للأكوام العميقة SANY SR360R

360kN · m super rated torque, heavy-duty rock socketed benchmark

Rated output torque of 360kN · m, far exceeding the Shanhe 300 model; Equipped with an Isuzu 6WG1 300kW high-power engine, with a maximum pressure of 290kN and a main roll lifting force of 360kN, it is suitable for drilling and rolling in moderately weathered and slightly weathered granite, thick pebble layers, and hard interlayers of the same level, and is suitable for ultra large and large-diameter rock socketed piles.
The maximum pore diameter is 2.5m, the maximum depth of the friction rod is 100m, and the interlocking rod is 65m. It is suitable for high-speed railway bridge piers, cross river bridges, wind power foundations, and heavy-duty pile foundations of super high-rise main buildings.

Five generation multi gear adaptive power head, automatically matching with geological formations

Five speed regulation+intelligent adaptive system for rock entry, the system automatically adjusts torque, speed, and pressure. It can quickly lift soft soil and cut hard rock with high torque and low speed, increasing comprehensive drilling efficiency by 15%; Built in multiple sediment seals+circulation forced lubrication, ensuring long-term high-intensity rock penetration and preventing high temperature damage to the gearbox.
The whole machine is equipped with triple buffering for lifting, rotating, and twisting, greatly reducing impact loads. The service life of the power head, drill rod, and reducer is significantly extended, reducing key breakage and drill rod breakage failures.

High flow heavy-duty hydraulic system, fast hoisting operation speed

Load sensing full power matching hydraulic, maximum lifting speed of 75m/min for main winch, and 36mm thick steel wire rope for large-diameter drum; The movements of soil throwing, drilling, and lifting are smoothly connected, with thick sediment in deep holes and strong lifting ability under stuck drilling conditions, resulting in lower risks of buried drilling.
