Kusamala Phungu Lapamwamba Kwambiri Kugwira Ntchito VerVA-LHN

Crace Crace imagwiritsidwa ntchito kwambiri, galimoto yolingana zambiri, yodziwika pamsika wapadera wamagalimoto, zigawo zikuluzikulu ndi Chasissions ndi kasupe, ndikusinthana kuti akwaniritse makina a galimotoyo, kudzera mumitundu yosiyanasiyana kuti mukwaniritse ntchito. Pali valavu yoyambira mu hydraulic system ya crane, yomwe imatha kusewera mothamanga pakugwa kwa crane, mkono wokulirapo, zomwe zingapewe kuwonongeka kwa chinthucho.
Valaining valavu imatha kusewera mothamanga mu crane: pomwe makina a crane kapena madontho omwe ali mu scalve am'mimba Kulamula kuti musunge ndalama, valavu yosavuta ndi valavu yoyendetsedwa kunja imagwiritsidwa ntchito m'malo mwa valavu yamagetsi. Izi ndichifukwa ngakhale valavu yothetsera valve imodzi ndi valavu yokhazikika yazomwe idachotsedwa ntchito, valavu yotsatirayi yawonjezerapo mabowo awiri, ndikugwetsa mabowo ena kuti amvetsetse bwino. Chachiwiri ndikuti makina oyendetsa bwino a valavu yasemphanayo iyenera kulumikizidwa mu Valavu, kotero kuti spul provitions ndi "ulesi", ndipo kuthamanga kwake sikusinthidwa chifukwa cha zovuta zakunja.
