Cov hlua hlauyog qhov hloov tau yooj yim thiab muaj zog ua los ntawm ntau cov xov hlau virted. Nws yog feem ntau siv nyob rau hauv lifting, hoisting, thiab kev siv haulling. Cov hlua hlau tuaj yeem raug faib ua ntau hom, txhua tus nrog nws tus kheej thiab cov ntawv thov hauv cov xwm txheej sib txawv. Thaum xaiv txoj hlua hlau, nws yog qhov tseem ceeb kom ua tib zoo xav txog qhov kev xav tau tshwj xeeb thiab ib puag ncig cov haujlwm kom paub meej thiab ua haujlwm tau zoo.
I. HLAU HLAU LIM LIM HOM:
1. Ib Leeg {{- strand xov hlau: ua los ntawm ib qho xaim xaim hlau, nws ib txwm siv rau cov khoom sib kis thiab nruj ntawm cov khoom siv me me. Vim tias lub zog tsawg ntawm ib tus hlau xaim, nws load {{{- cov kabmob muaj feem ntau, ua rau nws haum rau lub teeb ntim.
2. Ntau {- strand xov hlau: ua los ntawm ntau cov hlau sib tw, nws los ntawm ob hom: Muab kauv hlua hlua. Ntau - strand hlau hlau Muaj cov khoom siv hlau tsis muaj zog, thiab tsim nyog rau cov ntaub ntawv uas yuav tsum muaj lub zog hnyav, muaj zog thiab lub neej ntev.
(1) Muab kauv hlua: muab kauv hlua yog ua los ntawm sib ntswg ntau cov strands ntawm cov hlau xaim mus rau ib qho strand, thiab ua ke ntawm cov strands ua ke. Nws muaj zoo elasticity thiab muaj zog hnav tsis kam thiab yog tsim rau hoisting, traction thiab lwm lub sijhawm.
(2) Cov hlua sib pab ua: parallel hlua yog ua los ntawm sib ntswg ntau cov strands ntawm cov hlau xaim hauv parallel. Nws muaj lub zog siab tensile lub zog thiab tsim nyog rau hoisting thiab nqa ntawm cov tshuab loj thiab khoom siv.
Ii. Siv cov hlua hlau nrog cov qauv sib txawv:
1. Ib Leeg - strand xov hlau: Haum rau kev sib tw ntawm cov tshuab thiab khoom siv me me, thiab lwm yam.
2. Nws muaj cov yam ntxwv ntawm kev qaug zog tsis kam, hnav tsis kam thiab muaj zog load - cov kabmob muaj peev xwm.
3. Parallel Hlua: Haum rau hnyav thauj, ntev} deb} deb li nqa, xws li nqa cov tshuab loj thiab khoom siv, nkoj traction, thiab lwm yam.
III. Cov ntsiab cai ntawm cov hlua xaim xaiv:
1. Xaiv cov qauv tsim nyog qauv raws li phiaj xwm tsim nyog: Xaiv cov qauv hlua hlau tsim nyog ua kom muaj kev nyab xeeb thiab kev ntseeg tau.
2. Xaiv cov khoom siv tshwj xeeb tsim nyog thiab cov khoom siv ua haujlwm: Xaiv cov hlua khi, thiab xyuas kom haum rau cov hlua khi, thiab lwm cov khoom tau raws li cov phiaj xwm ua tau.
3. Xaiv cov txiaj ntsig tsim nyog raws li kev thauj khoom muaj peev xwm: Xaiv cov hlua tsim nyog cov hlua thiab kom muaj nuj nqis xws li qhov siab xav tau thiab Lifting qhov siab.
Kev kuaj xyuas tsis tu ncua thiab kev txij nkawm: Cov hlua hlau yuav tsum tau kuaj xyuas thiab tswj xyuas thaum siv cov xwm txheej los ntawm kev puas tsuaj lossis hnav.
