Qhov muag tau txais kev muag khoom ntawm sling rau truss cov kev tshwm sim ua ib qho "tsis pom cov ntaub thaiv" rau kev tiv thaiv cov khoom muaj txiaj ntsig. Piv nrog tsoos hlau hlau hlau hlau hlau hlau hlau los yog cov saw hlau, lub webbing muaj qhov chaw du thiab muaj kev ntxhib. Thaum nyob hauv kev sib cuag nrog cov cuab yeej siv, nws tuaj yeem tsim lub zog txawm - bearing nto. Txawm tias thaum cov khoom siv tau xav ntawm lub kaum sab xis lossis me ntsis shaken, nws yuav tsis khawb lossis extrusable teeb pom kev zoo thiab lub suab tawm suab. Cov yam ntxwv no yog qhov tshwj xeeb tshaj yog thaum tuav cov khoom siv kho qhov muag thiab txuag tau rau kev pheej hmoo tom qab kev ua haujlwm qeeb los ntawm cov cuab yeej ua haujlwm.
Ib qho ntxiv, qhov zoo ntawm sling rau truss kev tshwm sim ua haujlwm yooj yim yog qhov tseem ceeb. Lawv yog lub teeb pwm thiab khaws cia yooj yim. Ib qho 10 - 'meter' {matege}} Millimeters hnyav nrog qhov siab ntawm qhov truss rau kev xav tau qhov kev xav tau rau cov cuab yeej ntxiv. Thaum kev kho kom haum ib ntus yog qhov yuav tsum tau, qhov yooj ntawm lub webbing ua rau kev sib txhuam tawm los ntawm kev sib txhuam, kom ua haujlwm ntsiag to, ua haujlwm kom muaj kev ua haujlwm ntsiag to thiab ua haujlwm zoo ntawm kev tsim kho. Muaj dab tsi ntxiv, nws cov huab cua zoo tsis kam yog ib qho kev txhawb nqa ruaj khov, tsis yooj yim rau cov neeg caij nplooj zeeg lossis muaj hnub nyoog los ntawm kev ua txhaum cai ntawm theem kev tsim kho.
Nws yog qhov tseeb ntawm cov xeeb ceem uas sib npaug lub zog, kev tiv thaiv thiab yooj yim uas ua rau cov khoom lag luam truss, muab cov khoom lag luam tsis zoo ntawm kev ua yeeb yam.
