جهاز حفر دوار عالي الكفاءة في تشكيل الركائز XCMG XR400E

Strong rock penetration ability and high pile forming efficiency

400 kN · m high torque+300 kN strong pressure, high drilling efficiency in hard rock/gravel layers.
Three modes of power head: ordinary/rock entry/energy saving, suitable for different formations, taking into account efficiency and oil consumption.

Powerful and fuel-efficient

Cummins high displacement electronically controlled engine, with intelligent power adjustment in three gears, powerful under heavy loads, and fuel-efficient in soft terrain.
Load sensing hydraulic system+three in one heat dissipation, high system efficiency, low heat generation, and low fuel consumption.

Good stability and construction safety

H-type telescopic track chassis+large diameter slewing support, strong anti overturning ability, and more stable for deep piles/large diameter piles.
Double arm variable amplitude mechanism, optimized hinge point, stable operation, narrowable transportation, and convenient transition.

Durable, easy to maintain, and low cost

Single row rope main winch reduces the “biting” of steel wire rope structurally, prolongs rope life, and reduces rope replacement costs.
Key hydraulic components and seals are made of well-known brands, with high reliability, low failure rate, and easy maintenance.

High degree of intelligence

Standard intelligent control system: automatic soil throwing, bottom protection, cruise control, real-time monitoring of depth/verticality.
Comfortable operation, easy to pick up, reduces manual labor intensity, and minimizes human error.
