Qhov Kev Nyuaj Siab zais: Yog vim li cas Internal Fiber puas yog qhov tseem ceeb tshaj qhov hnav

Tus saib xyuas rigging ua ib qho kev tshuaj xyuas ua ntej siv. Cov nqa txoj siv sia  zoo li zoo-tsis muaj kev txiav, tsis muaj kev puas tsuaj, tsis pom kev hnav. Nws pom zoo siv. Ob xuab moos tom qab ntawd, lub sling ua tsis tiav nruab nrab-nqa, xa me nyuam rov 3-tuj steel beam. Kev tshawb nrhiav qhia qhov ua rau: kev puas tsuaj hauv fiber ntau uas tsis muaj leej twg pom.

Qhov no scenario tsis yog hypothetical. Nws ua si hauv kev cob qhia thiab chaw tsim kho txhua xyoo, thiab nws qhia txog qhov tseeb tseem ceeb hauv kev ruaj ntseg rigging: yam koj tsis pom tuaj yeem ua rau koj raug mob. Rau cov khoom siv nqa khoom siv , kev puas tsuaj hauv fiber ntau feem ntau txaus ntshai tshaj li qhov hnav tsis zoo vim nws tseem tsis pom txog thaum lub sijhawm tsis ua haujlwm.

 

Ntawm Dongfang Lishen , peb tau sim ntau txhiab tus polyester slings hauv peb qhov chaw tsim khoom. Peb cov ntaub ntawv tsis tu ncua qhia tau hais tias slings nrog pom saum npoo hnav feem ntau khaws cov seem tseem ceeb, thaum cov hlua uas zoo li pristine tuaj yeem ua tsis tau zoo vim yog kev puas tsuaj sab hauv.

 

Mechanisms ntawm Internal Fiber puas

 

Kev puas tsuaj sab hauv rau ib txoj siv nqa nqa  tau tshwm sim los ntawm ntau lub tshuab, tsis muaj ib qho uas tuaj yeem ntseeg tau los ntawm kev tshuaj xyuas qhov muag ib leeg.

 

Kev qaug zog los ntawm Cyclic Loading

 

Kev kawm tshawb fawb txog kev hloov pauv polyester webbing slings tau pom tias rov ua dua thiab tshem tawm - txawm tias tsis pub dhau lub peev xwm ntsuas - ua rau muaj kev qaug zog ntau dua. Txoj kev tshawb nrhiav pom tias webbing slings nthuav tawm peb theem sib txawv thaum lub sij hawm ncab:

 

 

Kev tshawb fawb xaus lus tias tom qab kev kho mob cyclic, lub zog tawg, elongation ntawm kev so, thiab qaug zog tiv thaiv ntawm PET webbing slings txo qis, txo qis kev pab cuam lub neej. Tseem ceeb heev, cov kev hloov no tshwm sim ua ntej ib qho kev taw qhia saum npoo pom tshwm.

 

Kev puas tsuaj

 

Ib qho kev poob qis, lub forklift pob, lossis txawm tias kev tuav tsis zoo tuaj yeem ua rau thaj chaw fiber ntau sib sib zog nqus hauv cov qauv  nqa txoj siv . Sab nrauv webbing yuav qhia me ntsis lossis tsis muaj qhov cim, tab sis cov xov paj sab hauv yog tawg. Tom ntej no loading concentrates kev nyuaj siab ntawm cov seem uas tsis muaj fibers, accelerating tsis ua hauj lwm.

 

Stitching Degradation

 

Kev tshawb nrhiav tsis txaus ntseeg tau ua los ntawm Maltese cov tub ceev xwm ntawm polyester web sling uas ua tsis tiav thaum lub nkoj cawm siav tau qhia tias cov xov xov stitching tau degraded loj heev nrog rau feem ntau ntawm lub cev sling. Kev tshuaj xyuas microscopic pom tias cov khoom siv stitching yog nylon, tsis yog polyester - thiab nws tau degraded ntau vim yog UV raug, thaum lub polyester webbing tseem zoo heev. Lub sling lub ntsej muag sab nraud tsis qhia txog qhov tsis muaj zog sab hauv. Qhov tshwm sim? Stitching rub tawm ntawm lub splice nyob rau hauv load.

 

Cov ntaub ntawv no qhia txog lub ntsiab lus tseem ceeb:  kev tshuaj xyuas yuav tsum xyuas tsis yog lub cev sling nkaus xwb, tab sis txhua yam khoom siv thauj khoom.

 

Vim li cas Kev Tshawb Fawb Pom Tsis Txaus

 

Kev tshuaj xyuas txhua hnub tsom rau qhov pom qhov tsis xws luag: txiav, puas, vuam splatter, tshuaj lom neeg kub hnyiab, thiab cov cim npe tsis raug. Cov qauv kev lag luam xws li ASME B30.9 thiab WAC 296-155-33825 tswj xyuas cov kev kuaj pom. Lawv yog cov tseem ceeb - tab sis lawv tsis txaus.

 

Kev lag luam kev sim ua los ntawm ICHCA International qhia qhov cuam tshuam loj ntawm ntau yam kev puas tsuaj ntawm lub peev xwm sling:

 

 

Daim ntawv ceeb toom tias qhov abrasion ua rau tsuas yog 1% muaj peev xwm txo qis - pom kev puas tsuaj, tab sis tsawg zog poob. Lub caij no, cov xwm txheej uas tuaj yeem ua rau muaj kev puas tsuaj sab hauv - pob qij txha, kev sib txhuam, kev txiav ntug - ua rau tsis ua haujlwm ntawm 30-71% qis dua qhov muaj peev xwm. Qhov kev sib raug zoo yog qhov tseeb:  qhov pom tsis pom kev sib haum xeeb yog qhov txaus ntshai tshaj qhov pom kev hnav khaub ncaws.

 

Kev lag luam scrapping cov qauv txhawb qhov no: lub tiaj lifting siv nto uas yog hnav tab sis zoo yuav tsum tau downgraded, tab sis yog hais tias lub puas nto mus txog 1/4 ntawm txoj siv dav , nws yuav tsum tau muab pov tseg. Ib yam li ntawd, yog hais tias lub load-bearing seam yog tawg, stitching yog hnav tawm, los yog lub fiber nto ua ntxhib thiab flaky, tam sim ntawd scrapping yuav tsum tau.

 

Txoj Kev 'Xav thiab Fold' Txoj Kev

 

Txij li kev soj ntsuam pom ib leeg tsis txaus, cov kws paub txog kev rigging siv cov txheej txheem tshuaj xyuas tactile:

 

Khoov lub sling raws nws qhov ntev. Mloog rau lub suab nrov nrov - qhov no qhia tias cov fibers puas lawm.

 

Compress lub webbing ntawm tus ntiv tes xoo thiab forefinger. Sib piv nrog ib tug paub-zoo sling. Ib qho kev xav mos los yog tsis sib xws qhia txog kev puas tsuaj sab hauv.

 

Tshawb xyuas thaj tsam splice kom zoo zoo.  Qhov no yog thaj chaw uas muaj kev ntxhov siab tshaj plaws. Xyuas seb puas muaj qhov sib txawv, tawv, lossis tsis sib xws.

 

Cov txheej txheem no, ua ke nrog kev kuaj pom, ua kom pom tseeb ntawm kev degradation sab hauv.

 

Tsim Kev Siv Archive

 

Dongfang Lishen qhov kev paub dhau los qhia tau hais tias kev taug qab nqa txoj siv sia ua haujlwm keeb kwm yog ib txoj hauv kev zoo tshaj plaws los tswj kev pheej hmoo ntawm kev puas tsuaj sab hauv. Daim ntawv teev kev siv yuav tsum sau tseg:

 

Hnub pib siv

 

Lift suav thiab load magnitude

 

Hom hitches siv

 

Environmental tej yam kev mob (kub, tshuaj raug, UV)

 

Kev tshuaj ntsuam xyuas

 

Cov ntaub ntawv no tso cai rau kev hloov pauv kev kwv yees, tso cai rau koj los so cov hlua ua ntej kev puas tsuaj sab hauv mus txog qib tseem ceeb. Raws li kev lag luam tus qauv sau tseg, slings hauv kev pabcuam hnyav yuav tsum tau kuaj xyuas tsawg kawg ib zaug hauv ib lub hlis twg, thiab kev kuaj pov thawj yuav tsum tau ua tsawg kawg txhua rau lub hlis hauv qhov chaw hnyav.

 

Tus nqi tiag ntawm kev tsis quav ntsej txog kev puas tsuaj sab hauv

 

Kev cuam tshuam nyiaj txiag ntawm kev nqa txoj siv tsis tau  txuas mus deb tshaj tus nqi ntawm txoj hlua. Xav txog:

 

Cov neeg raug mob lossis tuag taus

 

Kev puas tsuaj rau cov khoom siv kim lossis khoom siv

 

Qhov project qeeb thiab downtime

 

Kev tswj hwm kev nplua thiab cov nqi tshawb xyuas

 

Reputation puas thiab poob ntawm cov neeg siv kev ntseeg siab

 

Nyob rau hauv qhov xwm txheej ntawm fabrication cog tau piav nyob rau hauv thaum pib ntawm tsab xov xwm no, qhov kev tshawb fawb qhia tias lub sling tau raug rau ib tug poob siab load ob lub lis piam ua ntej. Qhov kev poob siab ua rau muaj kev puas tsuaj rau hauv fiber ntau, tab sis lub webbing sab nrauv tsis pom qhov cim. Tus thawj saib xyuas, tso siab rau kev tshuaj xyuas qhov muag ib leeg, tshem cov hlua kom siv txuas ntxiv. Tus nqi ntawm qhov kev txiav txim siab tau ntsuas hauv rau tus lej.

 

Summary and Practical Recommendations

 

Kev puas tsuaj ntawm fiber ntau yog qhov tseem ceeb tshaj qhov hnav vim tias nws tsis pom, kev loj hlob, thiab tuaj yeem ua rau tsis ua hauj lwm tam sim ntawd yam tsis muaj kev ceeb toom. Ib txoj hlua uas zoo nkaus li muaj kev nyab xeeb rau sab nraud tej zaum twb tau poob feem ntau ntawm nws lub zog.

 

Tiv thaiv koj pab neeg thiab koj cov khoom muaj nqis:

 

Tsis txhob cia siab rau kev kuaj pom ib leeg. Muab tactile checking rau hauv txhua qhov kev tshuaj xyuas ua ntej siv.

 

Tsim ib daim ntawv siv rau txhua qhov hlua.  Taug qab nqa suav thiab ib puag ncig raug.

 

Ua raws li cov txheej txheem nyiaj laus laus.  Thaum ib lub sling mus txog ntawm ntug ntawm cov txheej txheem seem-khaws nws.

 

Xav txog cov khoom sib xws. Raws li kev tshawb nrhiav hauv hiav txwv pom, cov ntaub ntawv tsis sib xws (nylon stitching ntawm polyester sling) tuaj yeem ua rau lub neej luv luv nyob rau hauv qhov raug UV.

 

Qhia koj pab neeg kom nkag siab txog cov txheej txheem kev puas tsuaj sab hauv - tsis yog los kuaj xyuas kev txiav thiab hnav.
