XR550D Rotary Drilling Rig

1. Equipped with an H-type hydraulically telescopic crawler chassis specially designed for rotary drilling rigs and a large-diameter slewing bearing, ensuring superior stability and convenient transport; the chassis features oscillating outriggers to assist with disassembly;

2. The hydraulic system adopts load-sensing technology, making the hydraulic system more efficient and more energy-saving; a three-in-one combined radiator system is used, featuring a compact structure and high heat dissipation efficiency;

3. Equipped with an imported Cummins engine, delivering strong power with sufficient power reserve to meet plateau construction requirements; noise and emissions meet Euro III standards;

4. The unique large triangular luffing mechanism and extra-large mast cross-section improve the stability of the equipment's working device and ensure hole-forming quality during the construction of large-diameter and ultra-deep pile holes;

5. The XCMG D-series single-layer-spooling main winch structure allows the main winch wire rope to be wound in a single layer throughout the full drilling depth, effectively solving the problem of wire rope "cross-lapping" and greatly extending the service life of the wire rope;

6. The power head offers a normal mode and a rock-socketing mode, respectively targeting soil and rock formations to improve construction efficiency; the power head features an automatic rotation function, with continuously adjustable speed in both normal and rock-socketing modes;

7. A centralized lubrication system is standard, for maintenance and
