Vacheri vakawanda vane pombi mbiri huru, saka vharuvhu yekuyamura ine maviri (inozivikanwawo sevhavha huru yekuchengetedza), zvichiteerana kudzora pombi huru imwe neimwe, uye pombi imwe neimwe inodzora zviito zvitatu, bhaketi uye ruoko rukuru runofamba nedivi rimwe. iboka, ruoko rwepakati, kutenderera uye kunze kwekufamba kwedivi iboka, ose maviri makuru mavharuvhu okuyamura (pilot rubatsiro mavharuvhu) anodzora zvinopesana zviito zvitatu.

Uye pakupedzisira ivo vanewo mavharuvhu avo ekuyamura echiito chega chega, seruwoko rwekusimudza uye ruoko runodzikisira rwune mavharuvhu avo ekuyamura. Ivhavha huru yekuyamura inonyanya kugadzirisa kudzvinyirira kwemapombi maviri makuru, saka kumanikidzika kwezviito zvitatu zvinotungamirirwa nepombi huru yakafanana, maererano nezvinodiwa, kana kudzvinyirira kwechiito chimwe chete kusina kukwana kana kwakanyanyisa, ipapo iyo yakaparadzana yekuyamura valve yechiito inogona kugadziriswa.

Pavhavha huru, pane musiyano wakajeka kubva kune mamwe mavharuvhu ekuyamura. Ivhavha huru yekuyamura yemucheri ane basa rekusimbisa ichave inopfuura imwe pilot pipe. Dambudziko revhavha huru yekuyamura kazhinji nderekuti chitubu chemukati chakaputsika kana kukundikana, iyo yevhavha yepakati yakapfekwa, uye kushanda kwese hakuna simba uye kudzvanywa hakugone kusimbiswa.

Mushure mekunge PC200-6 yakazara hydraulic excavator yatangwa, chishandiso chinoshanda chinogona kuona zviito zvakasiyana, asi pombi huru inotumira ruzha rusina kujairika.

Maererano nekuongorora kwekutanga, zvinotendwa kuti pombi inovharwa kana kuti dunhu remafuta rinosanganiswa nemhepo. Nokudaro, tanga wagadzirisa chigadziro chekushanda kune nzvimbo yekuona chiyero chemafuta, uye chengetedza kuti chiyero chemafuta che hydraulic tank chiri pazasi pezinga rakaderera rechinangwa chemafuta, iyo ndiyo nzvimbo yekushayikwa kwemafuta. Mushure mokubvunza mutyairi, mhete yekuisa chisimbiso yepombi yemafuta yepamusoro-soro inotungamira kukamuri isina tsvimbo yebhakiti rodhi cylinder yakatsiviwa nekuda kwekubuda kwemafuta panguva yebasa, asi mwero wemafuta hauna kuongororwa munguva mushure mekutsiviwa. Naizvozvo, chekutanga, iyo hydraulic mafuta tank inowedzerwa kune yakajairika mafuta level, uye bvunzo inoratidza kuti ruzha rusina kujairika rwakaderedzwa, asi richiripo; Zvadaro, kuburikidza nevhavha huru yepombi yepombi kune pombi huru mushure mekuedzwa zvakare, inowanikwa kuti ruzha rusina kujairika ruchiripo, zvichiratidza kuti ruzha harungagoni kukonzerwa zvachose nekusveta kwepombi.
