1 Key components of the hydraulic system. The piston nozzle assembly is likely to be used in the hydraulic control system of the XGC55 crawler crane. It is responsible for accurately adjusting the flow and pressure of the hydraulic oil, and driving the crane arm luffing, lifting and other actions. Refer to the hydraulic design of XCMG XGC series models. Wear-resistant materials (such as alloy steel) may be used, and it is suitable for high pressure working conditions (30-35MPa).
2 Flow and pressure control. Through the precise cooperation of the piston and the nozzle, load sensitive control (LS) is realized to ensure the stability during compound operation. May integrate pressure compensation function to avoid system overload
