Puas muaj kev nyab xeeb los siv cov nqa nqa uas tau khaws cia ntub?

Cov neeg ua haujlwm rigging ua tiav ib lub elevator rau hnub los nag. Cov lifting sling  yog ntub, tab sis nws zoo nkaus li zoo. Cov neeg ua haujlwm pov nws mus rau hauv qhov chaw cia khoom thiab txav mus rau txoj haujlwm tom ntej. Ob lub lis piam tom qab, cov hlua tau muab rov qab, tshuaj xyuas sai, thiab siv rau kev nqa qhov tseem ceeb. Txoj hlua tsis ua haujlwm. Kev tshawb nrhiav qhia tias yog vim li cas: mildew loj hlob thiab fiber ntau degradation los ntawm khaws cia ntub.

 

Qhov xwm txheej no muaj ntau dua li cov kws tshaj lij rigging feem ntau xav lees. Raws li kev lag luam kev taw qhia, slings uas ntub dej thaum siv los yog tu yuav tsum tau ua kom huab cua qhuav ua ntej cia. Khaws ib lub pas dej da dej caw cov kab mob mildew loj hlob thiab degradation fiber ntau. Canadian Center for Occupational Health and Safety (CCOHS) sau tseg ntxiv tias nylon slings poob 10-15% lub zog thaum ntub, txawm tias lub zog rov qab los thaum ziab.

 

Lishenflex  tau tsim cov hlua khi hlua khi rau ntau tshaj li ob xyoo lawm, thiab peb qhov kev paub dhau los qhia tau hais tias cov hlua khi tsis zoo yog qhov feem ntau saib xyuas qhov kev puas tsuaj thiab ua tsis tiav ntxov. Kev nkag siab txog qhov txaus ntshai ntawm kev cia ntub dej yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm sling thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.

 

Dej Risks

Cov kev pheej hmoo tseem ceeb cuam tshuam nrog kev khaws cia nqa slings ntub dej muaj xws li:

 

Fiber Swelling thiab Dimensional Hloov

 

Nylon yog cov khoom siv hygroscopic - nws absorbs noo noo los ntawm ib puag ncig. Raws li Wikipedia qhov nkag ntawm nylon, nylon absorbs noo noo nyob rau hauv ntau yam ntawm 2-8%  los ntawm qhov hnyav nyob ntawm cov av noo thiab kub. Qhov kev nqus no ua rau cov fibers swell, uas tuaj yeem cuam tshuam sling yooj thiab haum rau fittings.

 

Lub zog poob

 

CCOHS txheeb  xyuas tias nylon slings tuaj yeem poob 10-15% ntawm lawv lub zog thaum ntub, txawm tias lub zog rov qab los thaum ziab. Oregon OSHA  sau ntawv ntxiv tias nylon slings yuav poob txog 25% ntawm lawv lub zog thaum ntub dej vim yog nqus dej noo. Polyester slings, los ntawm qhov sib txawv, tsis cuam tshuam los ntawm kev ya raws tab sis tuaj yeem raug kev txom nyem los ntawm lwm yam kev degradation xws li mildew yog tias khaws cia ntub.

 

Mildew thiab Rot

 

Tej zaum qhov tseem ceeb tshaj plaws nyob rau lub sij hawm ntev ntawm kev cia ntub yog mildew thiab rot. Raws li Wikipedia nkag mus rau mildew, mildew yog ib hom kab mob fungus uas loj hlob hauv qhov chaw ntub dej, sov, thiab qhov cua tsis zoo. Thaum cov hlua khaws cia ntub, mildew tuaj yeem loj hlob ntawm qhov chaw thiab nruab nrab ntawm cov fibers, ua rau muaj kev cuam tshuam loj ntawm cov qauv fiber ntau. CCOHS tshwj xeeb txheeb xyuas cov pwm, pwm pwm, thiab rotting raws li cov xwm txheej uas ua rau cov hlua tsis muaj zog thiab yuav tsum tau tshem tawm tam sim ntawd los ntawm kev pabcuam.

 

Material-Specific Vulnerabilities

Tsis yog tag nrho cov khoom siv hluavtaws ua rau tib txoj hauv kev kom ya raws. Kev nkag siab txog qhov sib txawv yog qhov tseem ceeb rau kev saib xyuas kom zoo.

 

Tau qhov twg los: CCOHS Synthetic Web Slings Guide; Oregon OSHA

 

Raws li cov lus qhia, nylon slings feem ntau muaj kev cuam tshuam rau lub zog poob thaum ntub dej, thaum polyester slings yog qhov yooj yim rau mildew  yog khaws cia.

 

Lishenflex 's lab cov ntaub ntawv lees paub tias cov nylon slings kuaj ntub dej qhia tau hais tias 12-18% txo qis hauv kev tawg lub zog piv rau cov qauv qhuav, txhawb qhov tseem ceeb ntawm ziab nylon slings ua ntej siv. Polyester slings, los ntawm qhov sib txawv, qhia qhov sib txawv ntawm lub zog me me ntawm cov dej ntub thiab qhuav, tab sis tuaj yeem tsim pwm yog tias sab laug ntub rau lub sijhawm ntev.

 

Kev tshuaj xyuas tom qab ntub dej

Ua ntej ib qho ntub-kho lifting sling rov qab mus rau qhov kev pabcuam, yuav tsum tau kuaj xyuas kom meej. Raws li ASME B30.9 , cov hlua yuav tsum tau kuaj xyuas rau cov xwm txheej uas tuaj yeem cuam tshuam rau lawv txoj kev siv nyab xeeb. Tom qab ntub dej cia, tsom rau:

 

Kev soj ntsuam saum npoo

 

• Discoloration - tsaus me ntsis los yog staining yuav qhia tau hais tias mildew loj hlob

• Deg fuzziness los yog slipperiness - tej zaum yuav qhia tau hais tias fungal loj hlob

• Qhov tsis tau piav qhia - yuav qhia tau tias fiber ntau degradation

 

Tactile soj ntsuam

 

• Khoov lub sling - mloog cov suab nrov uas yuav qhia tau tias puas muaj fiber ntau

• Xav rau qhov chaw mos lossis tsis sib xws - tej zaum yuav qhia tias muaj kab mob mildew puas ntawm cov khaubncaws sab nraud povtseg

• Tshawb xyuas cov ntxhiab tsw txawv txawv - tsw ntxhiab tsw qhia tias muaj kab mob mildew loj hlob

 

Tag yam mob

 

Cov cim cim npe - yuav tsum nyob twj ywm. Yog tias daim ntawv puas lossis tsis raug cai, cov hlua yuav tsum raug tshem tawm ntawm kev pabcuam vim tias WLL tsis tuaj yeem txheeb xyuas tau.

 

Cov lus ceeb toom tseem ceeb: Ib qho ASME B30.9 , ib qho hlua uas pom muaj pwm, rot, lossis pwm yuav tsum raug tshem tawm ntawm kev pabcuam tam sim. Yog tias koj xav tias mildew loj hlob tab sis tsis paub meej, ua yuam kev ntawm kev ceev faj thiab tshem tawm cov hlua los ntawm kev pabcuam.

 

Kev ziab kom zoo thiab khaws cia

Txoj hauv kev zoo tshaj los tiv thaiv cov khoom ntub dej puas yog tsis txhob khaws cov hlua ntub dej.

 

Tshuab ziab khaub ncaws

 

Raws li kev coj ua zoo tshaj plaws hauv kev lag luam:

 

• So cov hlua nrog ib daim ntaub huv, qhuav kom tshem tawm cov av noo

• Dai los yog nteg nyob rau hauv ib qho chaw zoo ventilated

• Cia kom deb ntawm tshav ntuj ncaj qha - UV hluav taws xob tuaj yeem ua rau cov fibers puas

• Khaws kom deb ntawm qhov chaw tshav kub - qhov kub siab tshaj 90 ° C (194 ° F) tuaj yeem ua rau cov fibers mus tas li

• Tso cua kom qhuav ua ntej cia

 

Kev cia khoom

 

Raws li CCOHS thiab Lishenflex cov lus pom zoo:

 

• Txias, qhuav, zoo-ventilated cheeb tsam

• Nyob deb ntawm lub hnub ci ncaj qha, cov kav dej, cov nplaim taws qhib, thiab cov pa hluav taws xob

• Tawm hauv pem teb - ntawm pallets lossis racks los tiv thaiv kev nqus dej

• Kev tswj qhov kub thiab txias - zam cov cheeb tsam uas ua rau muaj qhov dej los yog dampness

 

Kev kuaj dej noo

Yog tias koj tsis paub meej tias lub lifting sling tau qhuav txaus, ua ib qho kev sim dej yooj yim:

 

1. Kov cov hlua - nws yuav tsum xav tias qhuav rau qhov kov

 

2. Squeeze lub webbing - tsis muaj noo noo yuav tsum pom los yog hnov

 

3. Ntsuas cov hlua (yog tias ua tau) - ib txoj hlua hnyav dua yuav qhia tau tias khaws cia noo noo

 

4. Txheeb xyuas qhov chaw cia khoom-yog tias qhov chaw cia khoom ntub dej, lub sling tej zaum yuav nqus tau noo noo los ntawm huab cua

 

Cov ntsiab lus thiab cov lus pom zoo

Kev khaws cov nqa sling ntub dej tsis yog tsuas yog kev saib xyuas me me xwb - nws tuaj yeem ua rau mildew loj hlob, fiber ntau degradation, thiab nyob rau hauv cov ntaub ntawv ntawm nylon, lub zog loj poob. Ib txoj hlua uas tau khaws cia ntub thiab pom tias muaj cov kab mob mildew lossis rot yuav tsum tau muab tshem tawm tam sim ntawd ntawm kev pabcuam.

 

Cov ntsiab lus tseem ceeb:

 

1. Nylon slings tuaj yeem poob txog 25% ntawm lawv lub zog thaum ntub - lub zog rov qab los thaum ziab, tab sis mildew puas tsuaj tas mus li.

 

2. Polyester slings tsis muaj zog los ntawm noo noo - tab sis mildew tuaj yeem loj hlob ntawm fibers yog tias khaws cia ntub

 

3. Mildew yog ib hom kab mob fungus uas loj hlob hauv qhov chaw ntub dej, sov, qhov cua tsis zoo - nws mus tas li degrades fiber ntau.

 

4. Ib txwm qhuav slings ua ntej cia - qhov no yog ib kauj ruam tseem ceeb tshaj plaws

 

5. Tshawb xyuas cov hlua ntub dej kom huv si - kom tsis muaj xim, tawv, tsw, thiab mildew

 

Lishenflex  tsim cov khoom siv polyester nqa cov hlua uas tsis tshua muaj kev cuam tshuam los ntawm ya raws li nylon, tab sis peb tseem hais ntxiv tias kev cia kom zoo yog qhov tseem ceeb rau kev siv hlua khi ntev thiab kev nyab xeeb.
