Ubukorikori hydraulic bwihuse ni pin gufata ubwoko bwihuse.Hano hari silindiri ya hydraulic iyobowe na solenoid valve ihuza ibyuma byimukanwa.Iyo silindiri ya hydraulic igenzurwa kurambura cyangwa gusubira inyuma, coupler yihuse irashobora gufata cyangwa gutakaza pin yimigereka yawe.Inyungu nini ya hydraulic yihuta cyane ni uko dukeneye kwicara gusa muri kabine ya excavator, kugenzura icyuma gihuza na valve ya solenoid kugirango uhuze byihuse guhindura umugereka byoroshye kandi byihuse.
