كفاءة عالية في الحفر السريع لثقب واحد، جهاز الحفر الدوراني SR205

Core construction performance advantages

Torque adaptation for small and medium-sized pile foundations, strong deep hole capability
Maximum output torque of 205kN · m, speed of 5-30rpm, suitable for 0.6-1.8m aperture; The maximum drilling depth of the friction rod is 64m, and the machine lock rod is 51m. It mainly focuses on deep hole pile foundations for industrial and civil construction, with outstanding drilling efficiency in clay, sand, and silty soil layers. SANY Phili.
The maximum pressure is 165kN, the lifting force of the main winch is 185kN, the lifting speed of the winch is fast, the amount of soil taken in a single operation is large, and the single hole pile forming cycle is short.
Compact body, flexible transition, and friendly to small spaces
The whole machine has a medium-sized tonnage of 63 tons, with a tail turning radius of only 3.8m; the transportation width can be reduced to 3.21m, without the need to split the mast, and can be directly transported by flatbed trucks. Sany Heavy Industry can operate in small working faces in urban and rural communities, urban villages, and basements.
The telescopic large width chassis has a working deployment width of 4150mm and widened tracks of 700mm. The grounding ratio is low, making it difficult for vehicles to sink on soft soil construction sites. The stability of the whole machine is strong for deep hole construction, and the verticality of the hole is high.

Power and Hydraulic: fuel-efficient, durable, and smooth output

Isuzu 212kW electronic fuel injection engine, economical and energy-saving
7.79L large displacement six cylinder power, multi gear adaptive fuel supply, with a comprehensive fuel consumption 10% -15% lower than similar equipment, and a significant advantage in long-term dry construction fuel costs; National III emission standard, applicable to both urban and rural construction sites, with a long maintenance cycle.
Specialized heavy-duty hydraulic system, resistant to impact and low failure rate
The fifth generation power head of Sany is equipped with a double buffering and shock-absorbing structure, which buffers and relieves force when encountering isolated rocks or hard interlayers, protecting the drill pipe and the entire machine; High flow variable control of the main pump, power distribution according to demand, automatic power reduction under light load of the empty drill, and automatic switching of torque mode between soft and hard formations.
Core hydraulic components are jointly customized with international manufacturers, with optimized pipeline layout and significantly reduced leakage points.
