Ultra high torque+deep pile capacity, suitable for hard rock

550kN · m torque+400kN pressure, can efficiently drill hard rocks above 330MPa.
Maximum drilling depth of 132m+3.5m aperture, suitable for super large pile foundations such as cross sea bridges, super high-rise buildings, and high-speed railway main towers.

Super stability, no shaking of ultra deep piles, high precision in drilling

H-type hydraulic telescopic track+large diameter slewing support+swinging leg, the whole machine is as stable as a rock.
Large triangular amplitude+ultra large cross-section box type drilling mast, with extremely strong torsional and bending resistance, and industry-leading verticality and drilling quality of ultra deep piles.

Single row rope main winch, completely solving the problem of “biting rope”

The XCMG D-series single row rope main winch operates in a single row winding state at full drilling depth, with no biting rope, long service life, and minimal maintenance.

Dual mode power head, adaptive to soil/rock layers

Normal mode: High speed, efficient drilling in soil layers.
Rock breaking mode: high torque, low speed, strong ability to break hard rocks.
The speed is continuously adjustable, suitable for complex geological conditions.

Efficient and energy-saving hydraulic system+reliable heat dissipation

The load sensing hydraulic system provides on-demand oil supply, with high efficiency and low fuel consumption.
Three in one combination radiator, compact structure, strong heat dissipation, suitable for high temperature/plateau working conditions.
