Improve construction safety XCMG XR220D Rotary Drilling Rig

Power and Hydraulics

Equipped with the Cummins QSL-325 electronically controlled turbocharged engine, delivering 242kW of power with ample reserves and economical fuel consumption. The hydraulic system employs positive flow + peak power control for on-demand output, ensuring fuel efficiency and rapid response, ideal for construction in clay, sand layers, and areas with minimal cobblestone deposits. The 220kN・m power head torque allows switching between standard and rock-breaking modes, balancing soil drilling and soft rock fragmentation.

Structurally stable and with high hole-forming precision

High-strength box-type mast + patented parallelogram luffing mechanism, featuring a wide luffing range and strong rigidity; multi-directional tilt adjustment of the mast, real-time verticality monitoring, and excellent hole straightness
Hydraulic telescopic crawler chassis + large-diameter slewing bearing ensures stable operation; compliant width after retraction facilitates transport without requiring oversized vehicles, offering significant advantages for road, bridge, and housing construction projects
Single-row rope main winch significantly reduces wire rope wear and extends lifespan; equipped with depth detection and a cab-mounted winch monitoring camera for easy observation of wire rope conditions
