Mphamvu yobweza yamagetsi imatengera ukadaulo wamagetsi kuti mukwaniritse mphamvu zodulidwa - kutuluka ndi kumbuyo ndikubwezeretsa ntchito zamitundu ya thirakitara, zomwe zimachepetsa ntchito mokwanira. Komabe, zigawo zazikuluzikulu za chassis, monga chibwibwi chonyowa chonyowa ndi valavu yowongolera ya Hydraulic Mafuta a Hydraulic kuposa thirakitala yamakina. Kamodzi wamafuta akagwiritsidwa ntchito kapena thirakitala chassis amasakanikirana, zitha kuchititsa kuti mafuta a hydraulic azikhala ocheperako, komanso oopsa kapena owuma.
