Smooth transitions XCMG XR220D Rotary Drilling Rig

Power and fuel consumption advantages

Equipped with Cummins QSL-325 electronically controlled turbocharged engine, with a rated power of 242kW and sufficient power reserve; Exclusive speed regulation program, powerful heavy load, low fuel consumption at idle speed, national three emission, which is suitable for most of the environmental protection standards of domestic construction sites.
The hydraulic system adopts negative flow+load sensitive constant power control, with fast hydraulic response, smooth action, reduced energy consumption under no-load, high composite action efficiency, and low heat generation during long-term continuous operation.

Strong chassis stability and convenient transportation

XCMG special heavy-duty telescopic track chassis, with a track gauge of 3500-4400mm that can be extended and retracted; Folding width of 3.5m, suitable for flatbed truck transportation; Expand the wide track, lower the ground contact ratio, and avoid sinking into muddy construction sites.
Large diameter heavy-duty slewing support, dual rotation deceleration braking, excellent anti overturning performance; 35% climbing ability, good passability on steep slopes and soft sites on construction sites.

Durable design of winch and drill rod

The patented single row rope main and auxiliary winches significantly reduce the compression and wear of the steel wire rope, and improve the service life of the steel wire rope; The maximum lifting speed of the main winch is 70m/min, and the drilling and soil lifting speed is fast.
Standard switchable drill rod: four section machine lock rod specializing in weathered rocks and hard soil layers; Five to six section friction rods are suitable for deep hole soil construction; The maximum drilling diameter is 2m, and the optional extended drill rod can construct a pile foundation up to 80 meters deep.

High structural rigidity and excellent drilling accuracy

High strength box type drilling mast, resistant to bending and deformation; The parallelogram double box variable amplitude mechanism has a wider support range, and the mast supports multi angle leveling (left and right ± 8 °, adjustable front and rear). The verticality of the pile foundation is controllable, and the drilling accuracy is high for XCMG Group.
The pressurized oil cylinder has sufficient thrust, and the soft rock pressurized drilling is powerful; The power head comes with an exclusive rock entry mode, with stable torque output and excellent performance against moderately weathered rock layers.
