Nyob rau hauv tib txoj kab uas hla, qhov qis dua nominal tensile lub zog ntawm ib txoj hlua hlau, ntau cov xov hlau ntawm ib txoj hlua, thiab qhov zoo ntawm cov hlau txoj kab uas hla, nws qhov yooj yim dua, tab sis qhov ntau nws yog hnav. Conversely, lub thicker lub hlau txoj kab uas hla ntawm ib tug strand, qhov yooj yim ntawm cov hlua hlau, tab sis lub zog nws hnav tsis kam. Yog li ntawd, ntau hom hlau hlua muaj lawv cov kev siv tshwj xeeb. Hauv kev ua haujlwm nqa, kev xaiv cov hlua hlau tuaj yeem ua raws li cov hauv qab no:
(1) 6X19 hlau hlua yog tsim rau kev ua txiv neej hlua, cables, thiab nqa slings, feem ntau yog siv nyob rau hauv cov chaw nrog me me dabtsi yog khoov loads los yog lub teeb hnav.
(2) 6X37 hlau hlua yog tsim rau khi ntau yam khoom thiab cov khoom siv hauv kev nqa cov haujlwm, nrog rau cov hlua rub rub thiab ua cov hlua nqa, tshwj xeeb tshaj yog tsim rau cov xwm txheej uas cov hlua yog khoov.
(3) 6X61 hlau hlua feem ntau yog siv los khi ntau yam khoom. Nws txoj hlua rigidity yog qhov tsawg, ua rau nws yooj yim rau khoov thiab haum rau qhov chaw uas tsis tshua muaj kev ntxhov siab. Tsis tas li ntawd, ib leeg - nteg xaim hlua muaj lub tiaj tiaj thiab mos, ua haujlwm zoo heev rau kev khoov qaug zog, thiab muaj zog heev. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias cov strands ntawm qhov tawg kawg yog qhov yooj yim rau loosening, thiab lawv muaj kev cuam tshuam rau kev sib hloov thiab twisting thaum tshem tawm cov khoom hnyav. Yog li ntawd, hom hlua hlau no feem ntau tsis siv ib leeg hauv kev nqa khoom. Interlocking hlau hlua, ntawm qhov tod tes, yog ib qho kev xaiv rau kev nqa thiab nqa cov haujlwm.
