Yintoni i-7:1 iFactor yoKhuseleko kwaye kutheni ibalulekile?

Umphathi wokurhwaphiliza ukhetha a ukuphakamisa isilingi  kulinganiswe ngeetoni ezi-2. Umthwalo unobunzima beetoni ezi-1.5-kakuhle ngaphakathi komda. Kodwa kwenzeka ntoni ukuba isilingi sothukile? Kuthekani ukuba umthwalo awujongwanga kakuhle? Kuthekani ukuba ukuwohloka kwemekobume kuye kwenza buthathaka imicu? I-sling ene-7: I-1 yokhuseleko factor inika isithinteli esibalulekileyo kwezi meko zingalindelekanga.

 

I-Lishenflex  ibisenza izilingi zokunyusa ezenziweyo ngaphezulu kweminyaka engamashumi amabini, kwaye umbuzo omnye esiwuva rhoqo kubasebenzisi bokugqibela ngowokuba: Ithetha ukuthini le nombolo ye-7:1 kwithegi eneneni? Impendulo ingundoqo ekukhuselweni okukhuselekileyo-kwaye ihlala ingaqondwa.

 

IFactor yoKhuseleko vs. Umda woMthwalo wokuSebenza: Ukuqonda umahluko

Ukuze uqonde i-7: I-1 yokukhusela i-factor, kufuneka uqale ukwahlula phakathi kwamagama amabini abalulekileyo: Umthwalo wokuSebenza (WLL) kunye nokuQhaphaza kwamandla  (okubizwa ngokuba yi-Minimum Breaking Load okanye i-MBL) .

 

Ngokutsho kweHercules Lifting guide , ubudlelwane phakathi kwezi zimbini zixabisekileyo zichongwa yi-design factor: WLL = Ukuqhawula Amandla ÷ Design Factor .

 

lwe- 7:1 Ukhuseleko  luthetha ukuba ukophuka kwesilingi kuphindwe kasixhenxe kwi-WLL yayo. Kwi-1-toni ye-WLL isilingi, amandla okuqhekeza ubuncinane iitoni ezisi-7. Njengoko kuchaziwe kwimigangatho yoshishino kuquka I-EN 1492-1 kunye ne-EN 1492-2 , lo mlinganiso ngowona mlinganiselo ofunekayo kwizilingi zokwenziwa.

Kutheni i-7:1 ye-Synthetic Lifting Slings?

Iindidi zezixhobo ezahlukeneyo zisebenzisa izinto ezahlukeneyo zokhuseleko:

 

Izilingi ze-Synthetic fiber zifuna into ephezulu yokhuseleko kunentambo yocingo okanye ityathanga kuba zisengozini ngakumbi kwizinto ezingqongileyo ezinokuthoba amandla ngaphandle kwesilumkiso esibonakalayo.

 

Ngokutsho kwe -WorkSafe WA's Mines Safety Bulletin No. 155 , ii-slings ezijikelezayo zokwenziwa zisengozini ngakumbi kumonakalo womzimba, ukukhanya kwelanga (i-ultraviolet), iikhemikhali, kunye nokushisa okugqithisileyo kunezinye iintlobo zokuphakamisa izixhobo. I-7:1 factor ibonelela ngesithintelo ngokuchasene nezi meko zingalindelekanga zehlabathi lokwenyani.

 

Njengoko i-Lifting Gear Direct  iphawula kwisikhokelo sabo semveliso, utshintsho lwamva nje lwamashishini luye lwafuna iintlobo ezithile zokuphakamisa ii-slings ukuba zibe ne-7: I-1 yokukhusela i-factor kunokuba i-5: i-1 ubudala i-slings-ithetha ukuba i-slings ngoku inomthwalo omncinci wokuqhawula amaxesha asixhenxe i-WLL yabo.

 

Ixabiso lehlabathi lokwenyani le-7:1 iFactor yoKhuseleko

I-7:1 factor ayifuni. Ibalela :

 

Umthwalo owothukileyo -ukufakwa komthwalo ngequbuliso okanye ukukhululwa

 

Ukunyakaza okuguquguqukayo - ukugungqa okanye ukuguquka ngexesha lokunyuswa

 

Ukonakaliswa kwendalo —iUV, ikhemikhali, okanye umonakalo wobushushu ekuhambeni kwexesha

 

Ukugqojozwa —ukugqabhuka, ukusikeka nokonakala

 

Izinto ze-engile -ukunciphisa amandla ekubambeni ukuminxa okanye kwibhaskithi

 

Ukunyamezelwa kwemveliso -ukwahluka kwezinto kunye nokwakhiwa

 

Ngokutsho kwe-CERTEX Denmark , izilingi ze-synthetic textile zisengozini ngakumbi kwimiphetho ebukhali, ukunxiba kunye nokukhuhlana, ukusikwa kunye neenyembezi, ubushushu obungaphezulu kwemilinganiselo yobushushu obuvunyelweyo, iikhemikhali ezingahambelaniyo, kunye nokuvezwa kwe-UV ngokuhamba kwexesha. I-7: 1 inkalo yokhuseleko ibonelela ngomda kobu bubuthathaka, iqinisekisa ukuba isilingi esithotywe ngumonakalo omncinci wokusingqongileyo sisenokuba namandla aneleyo okumelana nomthwalo waso olinganisiweyo ngokukhuselekileyo.

 

Uvavanyo lwelebhu ye- Lishenflex iqinisekisa ukuba kunye ne-10% ye-edge cut-enokuthi iphoswe kwitshekhi ekhawulezayo yokusetyenziswa-inokunciphisa umthamo we-sling nge-35%. I-7:1 factor iqinisekisa ukuba isilingi esinomonakalo omncinci sisenokugcina amandla awoneleyo okuphakamisa umthwalo waso olinganisiweyo. Yiyo loo nto eyona nto iphezulu yokhuseleko ingeyiyo nje imfuneko yokuthotyelwa-yimfuno ebonakalayo.

 

Indlela i-7:1 Umba woKhuseleko obonakala ngayo xa uSebenza

Ngaphantsi kwe-EN 1492-1 kunye ne-EN 1492-2, i-7: 1 inkalo yokhuseleko idityaniswe neempawu zomthamo ezinombala:

 

Umthombo: EN 1492-1/2 imigangatho yekhowudi yombala

 

I-DIN EN 1492-2  ithi izilingi ezijikelezileyo kufuneka zibe nokhuseleko oluphezulu lwe-7: 1, oku kuthetha ukuba i-WLL ye-1000 kg ihambelana nomthwalo wekhefu we-7000 kg. Inkcazo yemveliso ye-SpanSet iqinisekisa ukuba izilingi zabo zewebhu ezicaba zenziwe nge-7: 1 inkalo yokhuseleko, kunye nemveliso nganye enikwe isatifikethi sokuthotyelwa kunye nenombolo ye-serial eyodwa yokulandeleka.

 

Imigangatho egunyazisa 7:1

I-7:1 inkalo yokhuseleko igunyaziswe yimigangatho emininzi yehlabathi yezilingi zokwenziwa:

 

I-WorkSafe WA  iqinisekisa ukuba i-polyester round slings ihambelana ne-AS 4497: 2018, ubuncinane bomthwalo wokuqhawula buphindwe kasixhenxe WLL yabo , kwaye ngabanye bafaka ubungqina obuphindwe kabini kwi-WLL yabo.

 

Isishwankathelo kunye neeNgcebiso eziSebenzayo

I- 7: 1 inkalo yokhuseleko  yiparameter yoyilo olubalulekileyo olubonelela ngomda wokhuseleko phakathi kwamandla okuphakamisa isilingi kunye nomda womthwalo osebenzayo. Lo mba ubangela iimeko zehlabathi lokwenyani-umthwalo owothukileyo, ukonakaliswa kwemekobume, ukunxiba, kunye nee-angle factor-ezinokuthi zibeke esichengeni amandla esilingi.

 

Izinto eziphambili ezithathwayo:

 

I-1.7: 1 igunyaziswe yi-EN 1492-1 / 2 kunye ne-AS 4497: 2018  kwi-slings synthetic

 

2.I-WLL ayikophuli amandla —ungaze usebenzise ukophula amandla njengomda wokusebenza

 

3.Eyona nto iphakamileyo yokhuseleko kwi-synthetics kungenxa yokuba sesichengeni  kwi-UV, ubushushu, iikhemikhali, kunye nomonakalo emzimbeni.

 

4.Hlala ujonge i-sling tag -ibonisa zombini i-WLL kunye nokhuseleko

 

5.Hlola rhoqo -i-7:1 factor sisithinteli, hayi indawo yolondolozo olufanelekileyo

 

I-Lishenflex  ivelisa i-slings yokuphakamisa i-synthetic kunye ne-7: i-1 yokhuseleko factor, ehambelana ne-EN 1492-1 kunye ne-EN 1492-2 imigangatho. Iimveliso zethu zibonakalisa iimpawu zomthamo ocacileyo wombala, iinombolo ze-serial ezizodwa zokulandelela umkhondo, kwaye zifakwe ubungqina bokuqinisekisa ukuthembeka.

 

Ukuba ufuna uncedo lokuqonda iimfuno zokhuseleko lwemisebenzi yakho yokuphakamisa-okanye ufuna uncedo lokuqinisekisa ukuba izilingi zakho ziyahlangabezana nemigangatho eyimfuneko-nceda uthumele i-imeyile sales@lishenflex.com , kunye neqela lethu lobugcisa liya kubonelela ngenkxaso yomntu omnye.
