Kev siv fais fab yog ib yam khoom tshwj xeeb nqa khoom. Nws yog ntsia saum cov cranes thiab gantry cranes. Cov fais fab fais fab muaj cov yam ntxwv ntawm cov neeg me me, lub cev nyhav, kev lag luam yooj yim thiab kev siv yooj yim, thiab lwm yam. Nws yog siv rau hauv kev lag luam thiab cov chaw ua lag luam, kev lag luam, cov pov thawj thiab lwm qhov chaw.
Lub fais fab fais fab muaj ib qho qauv tsim. Lub fais fab fais fab nrog lub axis ntawm lub cev muaj zog mus rau lub axis ntawm lub nruas adopts ib tug cab iav. Cov kev tsis zoo yog: qhov ntev ntawm qhov loj, qhov ntev ntawm qhov dav, txheej txheem, tsis tshua muaj neeg kho tshuab, thiab nyuaj ua. Hydraulic system yog dual tswj. Txoj kev sib tshuam tswj tuav thiab lub sib nqus sib chwv sib sib zog nqus tau los tswj tau qhov siab. Lub tuam tsev tswj hwm hluav taws xob siv hluav taws xob tswj kom muaj kev ruaj ntseg ntawm kev tswj hwm.
Daim ntaub ntawv: Txwv, rub tawm, thau khoom thiab thau khoom ntawm cov khoom nyhav, nplua thiab kev siv cov roj siv roj, xws li kev lag luam thiab kev lag luam ntawm cov pob zeb loj thiab nruab nrab, steel qauv, thiab cov khoom siv kho tshuab, tsim nyog rau kev tsim kho thiab tsim kev lag luam, thiab kev siv choj ua lag luam thiab cov mines, Hluav taws xob, nkoj tsim, tsheb tsim, kev tsim, kev, kev txuas hniav, metallurgy, mining, nqhov dej, dej thiab lwm yam kev tsim kho vaj tse thiab kev tiv thaiv ntawm cov khoom siv cav.
