Ntev npaum li cas Kuv Yuav Tsum Hloov Kuv Li Lifting Slings?

A lifting sling ua tsis tiav thaum lub sij hawm nqa ib txwm. Lub load poob. Tsis muaj leej twg pom nws tuaj - lub sling zoo zoo thaum sawv ntxov check.

 

Qhov xwm txheej no muaj ntau dua li cov kws tshaj lij rigging feem ntau saib xyuas. Thiab nws feem ntau tshwm sim los ntawm kev saib xyuas ib leeg: khaws ib txoj hlua hauv kev pabcuam ntev ntev.

 

Tsis zoo li ntau cov khoom lag luam, lub lifting sling tsis tuaj nrog hnub tas sij hawm stamped ntawm nws daim ntawv. Cov neeg tsim khoom muab kev txwv kev ua haujlwm thiab kev nyab xeeb, tab sis tsis tshua muaj lub sijhawm hloov kho. Qhov no ua rau cov neeg siv kawg los txiav txim siab thaum lub sling tau mus txog qhov kawg ntawm nws txoj kev pabcuam nyab xeeb.

 

Lishenflex tau tsim cov hlua khi hlua khi rau ntau tshaj li ob xyoo lawm, thiab peb cov ntaub ntawv qhia tau hais tias kev hloov ntxov ntxov ua rau poob nyiaj, thaum lub sijhawm hloov pauv yuav muaj kev pheej hmoo. Qhov tseem ceeb yog nkag siab txog cov xwm txheej uas txiav txim siab lub luag haujlwm ntawm lub neej tiag tiag - thiab paub meej tias thaum twg yuav so nws.

 

Cia siab rau Kev Pabcuam Lub Neej los ntawm Sling Hom

Tsis muaj ob lub lifting slings muaj hnub nyoog tib yam. Kev pabcuam lub neej kev cia siab sib txawv los ntawm cov khoom siv, nrog rau cov hlua hluavtaws feem ntau muaj lub hauv paus luv luv ntawm kev ua neej nyob piv rau cov hlua hlau lossis cov saw hlau.

 

Raws li kev ua haujlwm ib txwm muaj, cov ntaub ntawv kev lag luam qhia tau hais tias cov khoom siv hluavtaws feem ntau muaj lub neej ntev ntawm 2-5 xyoos, thaum hlua hlua hlua tuaj yeem kav li 5-10 xyoo thiab cov hlua hlua yuav ntev tshaj 10 xyoo nrog kev saib xyuas kom zoo. Txawm li cas los xij, cov kev kwv yees no yog cov txheej txheem, tsis lav. Ib txoj hlua siv nyob rau hauv ib puag ncig hnyav lossis raug hnyav hnyav yuav xav tau hloov sai dua.

 

Raws li Canadian Lub Chaw Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb (CCOHS) , cov hlua hluavtaws tshwj xeeb yog qhov muaj kev cuam tshuam rau ib puag ncig - tshav ntuj, noo noo, thiab kub siab tshaj 90 ° C (194 ° F) tuaj yeem ua rau ob qho tib si nylon thiab polyester slings, thaum nylon slings puas los ntawm acids thiab polyester slings puas los ntawm alkalis . Qhov kev sib txawv ntawm cov tshuaj lom neeg no yog ib qho tseem ceeb ntawm kev xaiv: raws li tau piav qhia hauv Mazzella Tuam Txhab 'cov ntaub ntawv qhia cov khoom siv hluavtaws, nylon muaj kev tiv thaiv zoo rau alkalis tab sis tsis tsim nyog rau cov kua qaub, qhov polyester tiv taus cov kua qaub tab sis degrades hauv alkaline ib puag ncig. Cov tshuaj lom neeg tsis zoo no txhais tau hais tias cov hlua siv nyob rau hauv ib puag ncig hnyav yuav xav tau kev hloov zoo ua ntej lub neej ntev.

 

Rau slings siv nyob rau hauv tas li UV raug ib puag ncig, xws li cov chaw tsim kho sab nraum zoov, pom cov cim xws li tshuaj dawb los yog muaj zog ntxiv qhia tias degradation thiab yuav tsum tau tshem tawm tam sim ntawd los ntawm kev pab cuam. Liftex Slings phau ntawv qhia kev nyab xeeb sau tseg tias UV kev puas tsuaj tuaj yeem cuam tshuam rau cov khoom siv hluav taws xob hauv qhov sib txawv, los ntawm me me mus rau tag nrho cov degradation.

 

Lishenflex txoj kev tsim khoom tau lees paub tias lub sling txoj kev pabcuam lub neej yog txhais los ntawm nws tus mob, tsis yog nws lub hnub nyoog. Qhov no yog vim li cas kev hloov pauv raws li kev lag luam yog qhov kev coj ua zoo tshaj plaws hauv kev lag luam.

 

Txoj Kev Ntsuam Xyuas Raws Li Kev Hloov Hloov

Tsis yog kev cia siab rau lub sijhawm teem tseg, txoj hauv kev lag luam tus qauv yog kev tshuaj xyuas raws li kev hloov pauv: lub sling yuav tsum tau hloov thaum kev tshuaj xyuas qhia txog kev puas tsuaj uas cuam tshuam rau nws txoj kev siv nyab xeeb.

 

Raws li tau hais los ntawm ASME B30.9, cov hlua yuav tsum tau kuaj peb theem:

 

Kev tshuaj xyuas hom zaus leej twg ua

Ua ntej siv Kos Ua ntej txhua tus neeg nqa nqa / Tus Saib Xyuas

Kev soj ntsuam ntau zaus txhua hnub lossis ua ntej siv Tus Neeg Tsim Nyog

Kev soj ntsuam ib ntus Yam tsawg kawg ib xyoos ib zaug Tus Neeg Tsim Nyog Tsim Nyog/Tus Neeg Muaj Peev Xwm

ASME muab cov txheej txheem tshuaj xyuas ib ntus ntxiv raws li cov kev pabcuam: Kev Pabcuam Ib txwm - Txhua xyoo; Kev Pabcuam hnyav - Txhua hli mus rau Peb Hlis; Kev Pabcuam Tshwj Xeeb - Raws li kev pom zoo los ntawm tus neeg tsim nyog. CCOHS tau hais ntxiv tias qhov kev tshuaj ntsuam xyuas yuav tsum yog raws li qhov siv lub sling ntau npaum li cas, hom kev nqa nqa tau ua, thiab kev paub dhau los nrog cov hlua zoo sib xws.

 

Yuav tsum muaj cov ntaub ntawv tshawb xyuas ib ntus raws li ASME B30.9. Tus tswv hauj lwm yog lub luag hauj lwm rau kev tuav cov ntaub ntawv ntawm kev tshuaj ntsuam xyuas tsis ntev los no. Kev tsis tuaj yeem khaws cov ntaub ntawv soj ntsuam yog ib qho teeb meem tshwm sim uas tuaj yeem tiv thaiv lub tuam txhab kom tsis txhob ua raws li cov cai tswj kev nyab xeeb hauv chaw ua haujlwm.

 

Thaum Yuav Tshem Tawm Lifting Sling Tam Sim No

Qee hom kev puas tsuaj yog qhov tsis siv neeg rau kev so haujlwm tam sim ntawd. Raws li ASME B30.9 tus qauv, cov xwm txheej hauv qab no yuav tsum tau tshem tawm tam sim ntawd ntawm kev pabcuam:

 

Ncua lossis tsis pom daim npav cim npe

 

Acid los yog caustic burns ntawm lub cev sling

 

Cov pov thawj ntawm kev puas tsuaj thaum tshav kub kub - melted, charred, los yog brittle cheeb tsam

 

Qhov, kua muag, txiav, hnav, lossis snags uas nthuav tawm cov xov paj

 

Cov xov paj tawg lossis puas ntsoog - feem ntau pom tau los ntawm kev kov

 

Weld splatter uas nthuav tawm core yarns

 

Discoloration thiab nkig los yog tawv nqaij ntawm ib feem ntawm lub sling - tej zaum yuav qhia txog tshuaj lom neeg los yog UV puas

 

Knots nyob rau hauv lub cev sling

 

Fittings uas pitted, corroded, tawg, khoov, twisted, los yog tawg

 

Oregon OSHA tau txais kev cai rau cov khoom siv web slings qhia cov txheej txheem tshem tawm ntxiv: kev hnav tsis zoo, hmoov fiber ntau ntawm cov hlua, tawg lossis txiav fibers, kev hloov pauv hauv cov hlua loj lossis qhov sib npaug, hloov xim lossis rotting, thiab distortion ntawm kho vajtse. Cov kev cai kuj tseem hais txog kev nyab xeeb ntawm kev ua haujlwm kub-synthetic web slings ntawm polyester thiab nylon yuav tsum tsis txhob siv ntawm kub tshaj 180 ° F (82 ° C).

 

Cov lus ceeb toom tseem ceeb: Ib txoj hlua uas tau koom nrog hauv kev thauj khoom poob lossis xav tias yuav tsum tau muab tshem tawm tam sim ntawd ntawm kev pabcuam, txawm tias pom kev puas tsuaj tsis pom tseeb.

 

Kev txiav txim siab tshwj xeeb: UV, tshuaj lom neeg, thiab cua sov puas

Synthetic lifting slings yog tshwj xeeb tshaj yog yooj yim rau ib puag ncig degradation uas tej zaum yuav tsis pom tam sim ntawd.

 

Kev puas tsuaj UV: fading xim yog thawj daim ntawv ceeb toom. Hnub ci raug embritttles hluavtaws fibers, txo lub zog lub sij hawm. Kev pom kev pom ntawm UV degradation muaj xws li bleaching tawm ntawm sling xim, nce nruj ntawm sling khoom, thiab nto abrasion nyob rau hauv cov cheeb tsam uas tsis nquag nyob rau hauv kev sib cuag nrog lub load. Slings siv nyob rau hauv qhov chaw tiv thaiv UV txuas ntxiv yuav tsum tau kuaj xyuas ib xyoos ib zaug lossis ntau zaus nyob ntawm qhov raug mob hnyav.

 

Tshuaj lom neeg: Raws li tau sau tseg los ntawm CCOHS, nylon slings puas los ntawm acids thaum polyester slings puas los ntawm alkalis. Kev siv cov khoom siv tsis raug hauv ib puag ncig tsis zoo ua rau lub neej ua haujlwm luv luv thiab tuaj yeem ua rau tsis ua haujlwm tam sim ntawd. Piv txwv li, polyester slings yuav tsum tsis txhob siv nyob rau hauv fumes, vapors, los yog kua ntawm caustics, thiab nylon slings yuav tsum tsis txhob siv nyob rau hauv lub acids los yog phenolics.

 

Kev puas tsuaj thaum tshav kub kub: CCOHS txheeb xyuas qhov kub siab tshaj 90 ° C (194 ° F) ua kev puas tsuaj rau nylon thiab polyester slings. Tsis zoo li qhov pom kev txiav los yog puas tsuaj, kev puas tsuaj thaum tshav kub feem ntau tshwm sim raws li qhov chaw txhav lossis tawv nqaij uas tuaj yeem tsis pom thaum lub sijhawm tshuaj xyuas.
