Iphinifa elichotshozwayo lakhiwe ngomzimba wephinifa, isilinda esisebenza ngehydraulic, umhlathi onyakazayo kanye nomhlathi ogxilile.Umzimba wepliers wakhiwe ngamazinyo omhlathi, izindwani, namazinyo ajwayelekile.Ifakwe ku-excavator futhi ingeyokunamathiselwe kwe-excavator.
Izindlawu zokuchoboza manje sezisetshenziswa kabanzi embonini yokudiliza [1].Phakathi nenqubo yokudiliza, ifakwe ku-excavator ukuze isetshenziswe, ukuze kusetshenziswe umqhubi oyedwa kuphela we-excavator.
