Wopangidwira zida zamafakitale ndi mafoni, valavu ya M5 imapereka chitetezo chokwanira kuzovuta kwambiri, kupititsa patsogolo chitetezo chokwanira komanso magwiridwe antchito a hydraulic.

TheVavu Yothandizira Oyendetsa M4ndi gawo lofunikira lomwe limapangidwa kuti lipereke mpumulo wodalirika pamakina a hydraulic. Amapangidwa kuti asunge bata ladongosolo powongolera kupanikizika komanso kupewa kupanikizika kwambiri. Mtundu wa M4 umamangidwa kuti ugwire ntchito zosiyanasiyana, kupereka kuwongolera molondola komanso kukhazikika pansi pazigawo zopanikizika kwambiri.

TheVavu ya Hydraulic 336/B9042ndi gawo lowongolera bwino lomwe limapangidwa kuti ligwiritsidwe ntchito pamakina olemera, zida zamafakitale, kapena makina a hydraulic. Imagwira ntchito yowongolera kayendedwe ka madzi, kuthamanga, kapena mayendedwe mkati mwadongosolo, kuonetsetsa kuti ikugwira ntchito moyenera komanso yodalirika. Valavu iyi imamangidwa ndi zida zolimba kuti zipirire malo opanikizika kwambiri komanso zovuta, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zovuta. Kapangidwe kake kocheperako komanso magwiridwe antchito odalirika kumapangitsa kuti ikhale yofunika kwambiri pakusunga magwiridwe antchito ndi chitetezo.

TheR215-7 Vavu Yaikulu Yothandizirandi hydraulic pressure control valve yopangidwira kuti igwiritsidwe ntchito pamakina olemera, monga zofukula (mwachitsanzo, mtundu wa Volvo R215-7). Ntchito yake yayikulu ndikuteteza dongosolo la hydraulic pochepetsa kupanikizika kwakukulu, kuteteza kuwonongeka komwe kumachitika chifukwa cha kupsinjika kwambiri. Pamene kupanikizika kwadongosolo kumadutsa malire omwe adayikidwa kale, valavu imatsegula kuti itembenuzire madzi ochulukirapo kubwerera kumalo osungiramo, kuonetsetsa kuti ntchito yotetezeka komanso yogwira ntchito. Ndi gawo lokhazikika, lopangidwa mwaluso lofunikira kwambiri pakusunga kudalirika komanso moyo wautali wamagetsi amtundu wa hydraulic m'malo ovuta.

Zimatsimikizira kuti dongosololi limagwira ntchito mkati mwa malire otetezeka, kuteteza kuwonongeka kwa zigawo za hydraulic chifukwa cha kupanikizika kwambiri. Valavu imatseguka yokha kuti itulutse madzi ochulukirapo pamene kupanikizika kumadutsa poyambira, ndikubwereranso kumalo osungira. Izi zimateteza dongosolo kuti lisawonongeke ndikuwonjezera chitetezo cha ntchito. Mtundu wa DH500 mwina udapangidwa kuti uzitha kutengera kupsinjika kwakanthawi komanso mphamvu zoyenda, zogwirizana ndi zofunikira za zida zomwe zimagwira.
