Introduction Hydraulicexcavatorsarewidelyusedinearthmoving,civilengineering,mining,andotherfieldsduetotheirpowerfuldiggingcapabilitiesandhighmobility.However,traditionalhydraulicexcavatordiggingdeviceshavesomeshortcomings,suchaslowaccuracy,lowefficiency,andhighenergyconsumption.Inrecentyears,withthedevelopmentoftechnology,thehydraulicexcavatorindustryhasundergonesignificantchanges,butthebasicstructureofthediggingdevicehasnotbeenfundamentallychanged.
