High overall efficiency XCMG XR220D Rotary Drilling Rig

Power and Hydraulic System

Cummins QSL-325 electronically controlled turbocharged engine, 242kW, with sufficient power reserve, Euro III emissions, good fuel consumption control, and strong adaptability to high temperature and high-altitude working conditions
Hydraulic system adopts maximum power+positive flow control, load sensing, on-demand output, reduces overflow loss, and saves energy; The main winch adopts a single-layer rope structure, which greatly reduces the wear of the steel wire rope and extends its service life. The winch is equipped with depth detection and hole depth measurement is more accurate; The cab is equipped with an infrared camera to monitor the status of the main wire rope at any time
The power head supports switching between normal/rock breaking dual modes, and can handle soil layers, soft rocks, and pebble layers. It can also be configured with winch pressurization/sleeve pressurization

Structure and stability

Patent parallelogram variable amplitude mechanism, with a wide range of operation coverage; The drilling mast is a high-strength box shaped structure with strong rigidity and good resistance to torsion, ensuring the verticality of the drilled hole
Scalable H-type track chassis+large diameter slewing support: widening the chassis during operation to improve overall stability of the machine; Retracting tracks during transition, controllable transportation width, easy disassembly and assembly, and superior transition efficiency compared to models of the same level
The total weight of the machine is about 76 tons, with reasonable weight distribution. The diameter of the hole is 2m and the standard hole depth is 67m (special configuration can reach 80m), which is sufficient for small and medium-sized pile foundation projects

Intelligent control and construction accuracy

XCMG self-developed PLC intelligent control system, CAN bus; Automatic monitoring of mast inclination angle, automatic adjustment of verticality, real-time display of drilling depth, controllable pile hole quality, reducing the risk of collapse
360 ° full rotation vehicle, soil dumping at any angle, flexible construction site due to limited space
