High torque deep pile XCMG XR220D Rotary Drilling Rig

Power system advantages

Equipped with Cummins QSL9 electronically controlled turbocharged engine, with a rated power of 242kW and sufficient explosive power; Adapting to National III emissions, with controllable fuel consumption and low durability failure rate, it is not easy to experience high temperature and speed drop during long-term heavy-duty drilling
Adopting a positive flow+maximum power control hydraulic system, power is output as needed, with no load fuel saving and full drilling output torque. The action response is fast and the composite action is smooth. Compared with the old D-model, the power matching is optimized and the fuel economy is upgraded.

Special highlights of winch and wire rope

Single layer rope main winch eliminates the squeezing and wear of multi-layer steel wire ropes, significantly increasing the service life of steel wire ropes; The single-layer winding drilling depth sensor has precise distance measurement and zero deviation in hole depth reading.
The main winch is equipped with a steel wire rope monitoring infrared camera, which allows the driver’s cab to view the wear and tear of the steel wire rope, the status of the rope arrangement, and avoid the risk of rope breakage; The pressure hoist has sufficient thrust, and the drilling in hard soil layers is powerful under pressure.

Mast, fuselage and drilling accuracy

High strength box type thickened drilling mast, parallelogram amplitude changing mechanism, wide operation coverage, strong anti vibration and anti bending performance, small mast shaking for deep hole operation, and high verticality of drilling.
Scalable widened track special chassis, large diameter slewing support; The stability of the track deployment is strong during work, and the soft foundation is not prone to warping; Retract the track width and narrow it, making the whole vehicle easy to disassemble and transport, suitable for flatbed transportation.
The mast can be adjusted in multiple directions (with adjustable front to back and left to right inclination angles), and has strong adaptability to steep slopes and offset pile construction.
