The XE530E hydraulic excavator adopts PIC feedforward intelligent control, independent cooling system and other technologies, with the characteristics of AUX1 bidirectional merging and adjustable pressure flow, high efficiency, high reliability and low fuel consumption of the whole machine; New large displacement main pump, matched with PIC feedforward intelligent control technology, energy-saving under light load, high efficiency under heavy load, and comprehensive fuel consumption reduced by 3% -5%; Adopting an independent cooling system, it is more suitable for high-altitude and high-temperature environments. The fan speed is independently controlled, reducing fuel consumption by more than 30%; Standard mechanical telescopic chassis, widened chassis for better overall stability and stronger lifting capacity in working mode; Widely used in marble mines, non-ferrous metal mines, infrastructure projects, large earthworks and other working conditions, mainly for excavation, crushing, trenching, lifting and other operations.
