Product selling points

Adopting double boom luffing mechanism and H-type hydraulic telescopic crawler chassis for rotary drilling rigs, equipped with large-diameter slewing bearings, ensuring super stability and convenient transportation;

The Cummins engine is powerful and has three-speed power control. Users can select the appropriate gear according to the operating conditions to achieve the performance of three engines with one rig. The optimized three-speed power curve effectively reduces fuel consumption and use costs.

The hydraulic system adopts load sensing technology, superimposed total power control and power control technology to make the hydraulic system highly efficient, and adopts a three-in-one combined radiator system, which has a compact structure and high heat dissipation efficiency;

XCMG's proprietary single-row rope main hoisting structure effectively solves the problem of wire rope biting and greatly extends the service life of the wire rope;

The power head has normal mode, rock-entry mode and energy-saving mode. Users can choose the corresponding mode according to different geological conditions, which improves construction efficiency and reduces fuel consumption;

Multiple configurations: optional hoisting pressure, casing drive, etc., good expandability;

The centralized lubrication system is equipped as standard to facilitate maintenance and improve work reliability.
