Cov ntaub ntawv no tsuas yog hais txog cov ntsiab lus tseem ceeb rau kev siv Chain Lashings kom muaj kev nyab xeeb xwb. Tej zaum yuav tsum tau ntxiv cov ntaub ntawv no rau cov kev siv tshwj xeeb. Saib cov lus qhia dav dav txog kev txwv tsis pub thauj khoom, uas tau muab rau sab tom qab.
IB TXWM:
Tshawb xyuas cov saw hlau ua ntej siv.
● Xam lub zog lashing uas xav tau rau txoj kev xaiv ntawm kev txwv tsis pub thauj khoom.
● Xaiv lub peev xwm thiab tus naj npawb ntawm cov saw hlau kom muab tsawg kawg yog lub zog lashing uas tau xam
● Xyuas kom tseeb tias cov qhov khi ntawm lub tsheb thiab/lossis cov khoom thauj muaj zog txaus.
● Tiv thaiv cov saw hlau kom tsis txhob muaj cov npoo me me los yog txo qhov muaj peev xwm khi tau raws li cov lus qhia ntawm cov chaw tsim khoom.
● Xyuas kom tseeb tias cov saw hlau tau nruj kom raug.
● Ua tib zoo thaum tso cov saw hlau yog tias lub nra tsis ruaj khov txij li thaum muab cov saw hlau khi.
TSIS TXHOB:
● Siv cov saw hlau los tsa ib qho khoom thauj.
● Khi, khi, lossis hloov kho cov saw hlau.
● Cov saw hlau uas muaj khoom ntau dhau.
● Siv cov saw hlau khi rau ntawm ntug ntse uas tsis muaj kev tiv thaiv ntug lossis txo qhov muaj peev xwm khi.
● Tso cov saw hlau rau cov tshuaj yam tsis tau sab laj nrog tus neeg muag khoom.
● Siv cov saw hlau uas muaj cov txuas saw hlau uas tsis zoo, lub tensioner puas lawm, cov terminals puas lawm lossis daim ID uas ploj lawm.
Xaiv Qhov Kev Sib Tw Saw Kom Yog
Tus qauv rau kev khi cov saw hlau yog BS EN 12195-3: 2001. Nws yuav tsum tau kom cov saw hlau ua raws li EN 818-2 thiab cov khoom sib txuas kom ua raws li EN 1677-1, 2 lossis 4 raws li qhov tsim nyog. Cov khoom sib txuas thiab luv luv yuav tsum muaj lub cuab yeej ruaj ntseg xws li lub latch kev nyab xeeb.
Cov qauv no yog rau cov khoom qib 8. Qee cov chaw tsim khoom kuj muab cov qib siab dua uas, qhov loj me rau qhov loj me, muaj peev xwm khi tau zoo dua.
Cov saw hlau muaj ntau yam peev xwm thiab qhov ntev thiab ntau yam kev teeb tsa. Qee qhov yog rau lub hom phiaj dav dav. Lwm tus yog rau cov ntawv thov tshwj xeeb.
Kev xaiv yuav tsum pib nrog kev ntsuam xyuas cov zog ua rau ntawm lub nra. Lub zog lashing uas xav tau yuav tsum tau suav raws li BS EN 12195-1: 2010.
Tom ntej no xyuas seb cov qhov chaw khi ntawm lub tsheb thiab/lossis cov khoom thauj puas muaj zog txaus. Yog tias tsim nyog, siv ntau cov hlua khi kom faib lub zog mus rau ntau qhov chaw khi.
Cov saw hlau khi tau cim nrog lawv lub peev xwm khi (LC). qhia hauv daN (deca Newton = 10 Newtons) Qhov no yog lub zog kwv yees li sib npaug rau qhov hnyav ntawm 1kg.
Siv Cov Saw Lashings Kom Muaj Kev Nyab Xeeb
Xyuas kom tseeb tias lub tensioner ywj siab kom sib dhos thiab tsis khoov hla ntug. Xyuas kom tseeb tias cov saw hlau tsis ntswj lossis khi thiab cov khoom siv txuas nrog cov ntsiab lus lashing kom raug.
Rau ob feem lashings, xyuas kom meej tias cov khoom sib xws.
Xyuas kom tseeb tias cov saw hlau raug tiv thaiv los ntawm cov npoo ntse thiab me me los ntawm cov khoom ntim lossis cov khoom tiv thaiv ntug.
Lus Cim: Cov lus qhia ntawm cov chaw tsim khoom yuav tso cai siv rau ntawm cov npoo me me yog tias lub peev xwm lashing raug txo qis.
Kev Tshuaj Xyuas thiab Khaws Cia Hauv Kev Pabcuam
Cov hlua khi ntawm cov saw hlau tuaj yeem raug puas tsuaj los ntawm kev rub cov saw hlau hla cov npoo me me yam tsis muaj kev tiv thaiv ntug txaus. Txawm li cas los xij, kev puas tsuaj tuaj yeem tshwm sim tsis tau xav txog vim yog cov khoom thauj txav mus los thaum thauj khoom yog li ntawd yuav tsum tau kuaj xyuas ua ntej txhua zaus siv.
Cov saw hlau yuav tsum tsis txhob raug tshuaj lom neeg, tshwj xeeb yog cov kua qaub uas ua rau hydrogen embrittlement. Yog tias muaj kev ua qias tuaj yeem tshwm sim, cov saw hlau yuav tsum tau ntxuav nrog dej ntshiab thiab cia kom qhuav ntuj. Cov tshuaj lom neeg tsis muaj zog yuav ua rau muaj zog ntxiv los ntawm kev ua pa.
Yuav tsum tau kuaj xyuas cov saw hlau kom paub tseeb tias puas tsuaj ua ntej txhua zaus siv. Tsis txhob siv cov saw hlau yog tias pom muaj qhov tsis zoo hauv qab no: cov cim tsis nyeem tau; cov saw hlau khoov, ntev lossis muaj qhov, cov khoom sib txuas lossis cov khoom siv kawg tsis zoo lossis muaj qhov, cov xauv kev nyab xeeb tsis ua haujlwm lossis ploj lawm.
Cov saw hlau yuav maj mam lwj zuj zus. Lub LEEA pom zoo tias yuav tsum muaj ib tus neeg txawj ntse los tshuaj xyuas lawv tsawg kawg txhua 6 lub hlis thiab sau cov ntaub ntawv txog qhov tshwm sim.
Cov saw hlau tsuas yog yuav tsum tau kho los ntawm ib tus neeg uas muaj peev xwm ua li ntawd xwb.
Rau kev khaws cia mus sij hawm ntev, qhov chaw khaws cia yuav tsum qhuav, huv si thiab tsis muaj tej yam tsis huv.
