جهاز الحفر الدوراني XCMG XR220E منخفض التلوث

Efficient power, stable and powerful

220kN · m Golden Torque: Suitable for common formations such as clay, sand, gravel, and moderately weathered red sandstone, with high efficiency in small and medium-sized pore formation.
Cummins Power+Kawasaki Hydraulic: load sensing matching, smooth operation, and more economical fuel consumption; Single row rope winch reduces wire rope wear and increases lifespan by 2-4 times.
5m long stroke pressurization: Long casing/deep hole construction is more stable, reducing the risk of rod jamming and hole collapse, and the quality of hole formation is controllable.

Intelligent, reliable, and user-friendly operation

PLC electronic control+high-definition display: real-time display of drill pipe position, hole depth, and posture; Integrated overload/limit/anti misoperation protection, high safety redundancy.
Parallel quadrilateral amplitude changing mechanism: has a large operating range, high strength of the mast box structure, and more stable drilling accuracy and verticality.
Humanized driver’s cabin: suspended seats, low noise, light operation, and less fatigue during long-term work.

Full range adaptation and transition compliance

One machine with multiple functions: supports conventional rotary excavation, full casing, CFA long spiral and other construction methods, and does not collapse in soft soil, quicksand, and groundwater rich formations, with a wide coverage of working conditions.
Narrow transportation+track extension: The whole machine weighs about 70 tons, and the transportation height after folding the mast is ≤ 3.4m. It can be legally driven with a width of 3.5m and is easy to transfer.
Scalable track: It can operate freely in narrow construction sites and urban enclosures, with strong adaptability.

Maintain economic and residual value stability

Modular design+centralized lubrication: quick disassembly of components, maintenance can be completed in 1 hour; Automatic lubrication reduces manual labor and extends the lifespan of vulnerable parts.
XCMG Service Network: Universal parts, fast after-sales response, low maintenance costs, and good circulation in the second-hand market.
