Hlau hlua nyob rau tib txoj kab uas hla thaum lub nominal tensile lub zog yog qis dua, ntau steel hlau nyob rau hauv txhua txoj hlua, lub finer lub cheeb ntawm cov hlau, qhov zoo dua cov hlua txoj kev yooj yim, tab sis cov hlua yog ib qho yooj yim rau hnav.Conversely, lub thicker txoj kab uas hla. ntawm cov hlau hlau nyob rau hauv txhua txoj hlua ntawm txoj hlua, qhov ua rau txoj hlua tsis yooj yim dua, txoj hlua yog resistant rau hnav.
Yog li ntawd, ntau hom hlua hlau, nws txoj kev siv yog txawv. Raws li qhov xav tau tiag tiag ntawm kev nqa thiab nqa cov haujlwm, feem ntau, kev xaiv cov hlua hlau tuaj yeem suav tias yog cov hauv qab no.
(1) 6 × 19 hlau hlua yog siv los ua hlua hlua hlua, rub hlua thiab ua lifting rigging, feem ntau yog siv rau khoov load me me los yog raug kev txom nyem los ntawm hnav thiab tsim kua muag ntawm qhov chaw.
(2) 6 × 37 steel hlau hlua yog siv los khi ntau yam khoom thiab cov khoom siv hauv kev nqa nqa, nrog rau cov xov nyob ib ncig ntawm lub rubey thaiv thiab ua rigging rau nqa qhov hnyav. Siv tau thaum txoj hlua yog khoov.
Lang nteg steel hlau hlua, qhov saum npoo yog tiaj tiaj, muag muag, nrog zoo khoov qaug zog tiv thaiv, ntau ruaj; nws qhov tsis zoo yog tias txoj hlua lub taub hau yooj yim xoob, yooj yim tig thaum dai cov khoom hnyav, yooj yim rau curl thiab kink, thiab yog li ntawd yuav tsum tsis txhob siv rau hauv kev nqa ib leeg. Lifting thiab hoisting cov haujlwm feem ntau yog siv los khaws cov hlua sib txuas sib txuas.
