Nkag siab txog pob khawm kho vajtse thiab rooj tog zaum screws pib nrog rooj tog. Feem ntau cov pob khawm zoo nyob rau hauv kev ua lag luam siv carbon structural steel. Lawv yog thawj kub-kuav los tiag steel strips thiab ces txias-dov mus rau hauv steel strips nrog ib tug tuab ntawm tsawg tshaj li 4 hli. Txij li thaum dov ntawm chav tsev kub tsis tsim cov hlau oxide, qhov zoo ntawm cov khaub thuas dov strip steel yog qhov zoo. Cov tuam txhab lag luam siv cov qauv zoo, cov qauv zoo ntawm cov ntsia hlau kom ua tiav cov khoom siv hluav taws xob, txhim kho kev tsim khoom, txo cov nqi seem, thiab txuag nqi zog. Tsis tas li ntawd, qee qhov hinges tseem tuaj yeem kho qhov kaw lub qhov rooj ntxiv rau kev hloov kho peb sab. Feem ntau, nrog lub zog muaj zog Nws yog nyob ntawm qhov siab thiab hnyav qhov rooj. Nws yog siv rau lub qhov rooj nqaim thiab qhov rooj iav. Koj tsuas yog yuav tsum tau kho lub caij nplooj ntoos hlav quab yuam. Tig lub pob khawm ib tig los kho cov rooj tog kho vajtse screws, thiab lub caij nplooj ntoos hlav quab yuam yuav raug txo los ntawm 50%.
Ib qho khoom siv rooj tog ntsia hlau uas kho lub pob khawm. Kev ua haujlwm ntawm cov ntsia hlau yog ua kom cov khoom siv hauv chav ua noj tawm sab nraud, haum rau protruding tom qab kaw lub i. Cov ntsia hlau rau sab laug yog rau tuav. Piv txwv li, lub pob khawm zoo tuaj yeem txiav txim siab los ntawm cov hauv qab no: (1) Cov tsos yog du thiab muag heev, pob khawm steel phab ntsa yog thicker, thiab nws hnyav dua thaum pib (nws txhais tau hais tias cov khoom yog qhov zoo, pwm yog zoo, thiab cov hlau yog zoo) Nruab nrog hydraulic shock absorbers los yog thawj shock absorbers; Muaj ntau hom hinges. Nyob ntawm seb hom ntawm nws lub hauv paus, muaj cov hom ruaj khov thiab ib qho tuaj yeem raug tshem tawm. Yog tias koj ua raws li nws txhais tes, muaj swb-hauv lossis clip-on hinges.
