Cov hlua khi hauv qab yog cov tub ntxhais thauj khoom-cov kabmob ntawm cov crane, uas muaj qhov sib txuas, rub lub thaiv, cov kabmob, lub xauv kev nyab xeeb thiab cov khoom sib txuas, thiab yog siv los nqa cov khoom ruaj ntseg. Nws lub luag haujlwm tseem ceeb yog txhawm rau cuam tshuam lub zog ntawm txoj hlua hlau los ntawm lub rubey thaiv, thiab ua kom tiav ntau- lub kaum sab xis nqa nrog tus nuv rotatable. Tus nuv lub cev tawg, qhib deformation, kaw kaw thiab kev sib hloov yooj yuav tsum tau kuaj txhua hnub. Cov khoom tseem ceeb uas hnav dhau qhov txwv yuav tsum tau hloov kom tsis txhob muaj kev pheej hmoo ntawm kev tawg.

Crane hooks yog cov khoom tseem ceeb ntawm cov khoom nqa nqa, siv los nqa cov khoom hnyav. Lawv feem ntau yog ua los ntawm siab -lub zog alloy steel thiab muaj cov khoom xws li hnav tsis kam thiab cuam tshuam. Cov qauv ntawm lub crane nuv muaj xws li lub cev nuv, nuv lub caj dab thiab kev ruaj ntseg xauv, uas yuav tsum tau xyuas tsis tu ncua rau hnav thiab deformation. Cov hom muaj xws li ib qho hooks thiab ob chav hooks, uas yog siv dav hauv kev tsim kho, chaw nres nkoj thiab kev tsim khoom lag luam.

Lub reducer ceev (tseem hu ua reducer lossis gearbox) yog lub zog xa hluav taws xob siv los txo qhov ceev thiab nce lub zog. Nws yog dav siv nyob rau hauv industrial machinery, automation khoom, tsheb thauj mus los thiab lwm yam teb. Nws hloov lub siab ceev thiab qis torque tso zis ntawm lub cev muaj zog lossis lub cav mus rau hauv qhov qis qis thiab siab torque tso tawm los ntawm cov qauv sib kis xws li lub zog, lub zog cua sov, thiab lub ntiaj teb lub zog kom tau raws li qhov xav tau ntawm cov khoom siv sib txawv.
