XGC55 crawler crane：

The XGC55 crawler crane is a new generation of crawler crane product successfully developed by XCMG following QUY55 crawler crane. While inheriting the advantages of the old products, the new generation pays more attention to improving the performance, operating efficiency, convenience for disassembly and transportation, and comfort of operation. The system is mature and reliable, and the safety devices are complete. It is equipped with a self-erecting function, main winch quick release function, one key switch function, an engine cold start device, a winch monitoring system, a hydraulic high-pressure bypass filter system, and an electronic level gauge, anti-lightning system, travel commutation function, the main boom catwalk and other advanced technology, all aspects of performance are superior to the domestic counterparts.
