Ndinogona Kujoina Mafurati Maviri Pamwechete Kuti Ndiwedzere Hurefu?

Vashandi vekugadzira zvinhu vari kugadzirira lift. Mutoro wacho wakareba mamita gumi nemashanu, asi chete flat sling iripo ndeye 10 tsoka. Mutariri anoda chipfuramabwe chakareba-uye nekukurumidza. Muedzo wekungobatanidza zvipfuramabwe zviviri pamwechete unenge usingadzivisiki.

Asi mutariri wemagetsi anoziva zviri nani. Zvinoenderana neOSHA 1910.184(c)(2) , pese panoshandiswa chero chipfuramabwe hachifanirwe kupfupikiswa nemapfundo kana mabhaudhi kana zvimwe zvigadziriso. ASME B30.9 inodawo kuti zvipfuramabwe zvirege kumonyoroka, kupfupikiswa, kurebeswa, kusungwa kuita mapfundo, kana kubatanidzwa neknotting.

Lishenflex yanga ichigadzira machira ekugadzira machira kwemakumi emakore, uye ruzivo rwemumunda rwedu runoratidza kuti zvipfuramabwe zvisizvo zvinokonzeresa zviitiko zvekubira . Chiito chakareruka chekusunga zvipfuramabwe zviviri pamwe chete chinogona kuderedza simba ne50% kana kupfuura, zvichigadzira njodzi yekutadza nzvimbo pasi pemutoro.

1. Sei Kujoinha Slings zvakananga kune ngozi

1.1 Knots uye Girth Hitches-Yakanyanya Kuderedza Simba

Nzira yakajairika yekubatanidza zvipfuramabwe zviviri ipfundo kana girth hitch (lark's foot). Nzira mbiri idzi dzinogadzira mabhende akapinza anoisa kushushikana panzvimbo diki. Zvinoenderana nekuyedza kunoratidzwa munharaunda yekukwira yeUK, girth hitch inogona kuderedza simba rekupfura neanosvika 50% . Kunyangwe pasi peKusimudza Operations uye Lifting Equipment Regulations (LOLER), kudzikiswa kunenge 20% kana kuchiitwa nezvipfuramabwe zvakaenzana.

SpanSet inoyambira kuti chero rudzi rwechipfuramabwe — chipfuramabwe chewebhu, chipfuramabwe chakatenderera, tambo dzewaya, cheni — hachifanirwe kuvharwa. Kusunga pfundo kuchaita kuti zvikamu zvakasungwa zvigure mukati memumwe uye zvokonzera kukuvadza, izvo zvinogona kupedzisira zvakonzera tsaona inouraya.

1.2 Iyo 'Pulley Effect' uye Kucheka Chiito

Kana zvipfuramabwe zviviri zvabatanidzwa uye kuiswa pasi pemutoro, nzvimbo yekubatanidza inoita senge pulley. Zvipfuramabwe zvinofamba zvichipesana pasi pekukakavadzana kwakanyanya, zvichigadzira kukweshera uye kucheka zviito zvinogona kucheka mafibhi. SpanSet inotaura zvakajeka kuti zvipfuramabwe zvakasungwa zvinokonzeresa kuti zvikamu zvidimbure mukati memumwe nemumwe, zvichigadzira kukuvadzwa kunogona kupedzisira kwakonzera tsaona inouraya. Ichi ndicho chikonzero OSHA uye ASME zviyero zvinorambidza kujoinha neknotting-kukuvara kuri kufambira mberi uye kazhinji kusingaonekwe kusvika kukundikana.

1.3 Mitemo Yemaindasitiri Inoirambidza

Per WAC 296-155-55825 , vashandirwi havafanire kupfupisa kana kurebesa slings neknotting kana kumonyorora. Izvi zvinoshanda kune synthetic web slings chaizvo. Pasi peASME B30.9 , mapfundo mune chero chikamu chechipfuramabwe izvikonzero zvekubviswa kubva pabasa. Izvi zvinoreva kuti chipfuramabwe chakasungwa—kunyange kamwe chete—chinofanira kubviswa.

Gwaro rekuongorora Makambani eMazzella rinoronga 'mapfundo mune chero chikamu chechipfuramabwe' sechimiro chinoda kubviswa pabasa, uye zvakare rinoti zvipfuramabwe hazvizomonyororwa, kusungwa kuita mapfundo, kana kubatanidzwa neknotting. Saizvozvo, Kusimudza Operations uye Kusimudza Equipment Regulations (LOLER) inorambidza knotting senzira yekupfupisa kana kujoinha zvipfuramabwe.

2. Zvinotaurwa neMitemo

3. Nzira Yakarurama Yokuwedzera Kureba kweSling

Kana maviri akafuratira slings achifanira kubatanidzwa kuti awane hurefu hunodiwa, nzira chete yakachengeteka iri kushandisa yakatsaurirwa kusimudza Hardware.

3.1 Matani

Shackles ndiyo nzira yakajairika yekubatanidza zvipfuramabwe. Ziso rechipfuramabwe rega rega rakanamirwa papini yechakekeri kana uta, zvichigadzira nzvimbo yekubatanidza inoremerwa. TS EN 1492-1 inotsanangura kuti machira akarukwa akapfava anogona kushandiswa nemagetsi, kunze kwekunge maitirwo akayerwa zvakanaka uye achienderana nechipfuramabwe.

Zvinodiwa zvakakosha kana uchishandisa matani :

• Shackle WLL inofanira kuenzana kana kudarika WLL yechipfuramabwe

• Shackle size inofanira kukwana maziso echipfuramabwe pasina kusunga

• Iyo shackle pini inofanirwa kusimbiswa zvakanaka uye yakachengetedzwa

3.2 Joker Hooks uye Dedicated Connectors

SpanSet inokurudzira iyo Joker Hook seimwe nzira yakachengeteka yekuwedzera kureba kwechipfuramabwe. Iyo Joker Hook inoshanda sechibatanidza chekubatanidza kuti ubatanidze hurefu huviri hwematenderedzwa kana mabhii slings pamwe chete, zvichiita kuti iwe ugadzire chipfuramabwe chakareba pazvinenge zvichidikanwa. Iyo ine simba rekusimudza, mavara makodhi, uye inoenderana neEN 1492 zviyero.

3.3 Mabatanidza Akapfava (Kana Abvumidzwa)

Liftex uye vamwe vagadziri vanobvumira zvinyoro-nyoro zvibatanidzi chete kana iyo yekubatanidza yaitwa kune yakanyatso rated hardware fitting-kwete zvakananga kupfura-ku-ku-sling. Iyo yekuChina yakajairwa GB/T 25854 yakafanana inoda kuti zvese zvinobatanidza zvikamu zviyererwe uye zvienderane neiyo chipfuramabwe's WLL, uye zvikamu zvese zvinofanirwa kuongororwa kuti hazvina kupfeka uye kukuvara zvisati zvashandiswa.

4. Chii Chinoitika Kana Ukashandisa Knotted Sling?

• Chipfuramabwe chinofanira kuraswa : Pa ASME B30.9, mapfundo anoda kubviswa pabasa.

• OSHA citations : OSHA inogara ichidudza vashandirwi pakushandisa mapfundo akaroverwa. Mune inokwana nyaya imwe chete yakanyorwa, citation yakapihwa ye synthetic web sling yaive yakasungwa mupfundo.

• Kuderedza simba : A girth hitch inoderedza simba ne 20-50%, zvichienderana nenzira yekubatanidza.

• Njodzi yekutadza njodzi : Iko kupokana uye kucheka chiito papfundo kunogona kukonzera kutadza kamwe kamwe pasi pemutoro.

5. Pfupiso uye Mazano Anoshanda

Kujoinha slings maviri akafuratira neknotting kana girth kurova kunorambidzwa neOSHA, ASME, EN 1492-1, uye LOLER . Iyo tsika inoderedza simba rekupfura ne20-50%, inogadzira kukuvara kunofambira mberi kubva mukukwesha, uye inofumura vashandisi kunjodzi yekutadza.

Zvokudya zvakakosha:

1. Usambofa pfundo kana girth-hitch slings pamwe chete - inorambidzwa nemaitiro akawanda uye inoderedza simba zvakanyanya.

2. Shandisa Hardware yakatsaurirwa -shackles, Joker Hooks, kana zvimwe zvinongedzo-yakatemerwa zvibatanidza ndiyo chete nzira dzakachengeteka

3. Mechi ratings - ese anobatanidza hardware anofanirwa kuve neWLL yakaenzana kana yakakura kupfuura WLL yechipfuramabwe.

4. Ongorora kubatanidza - tarisa kuti hardware inokodzera maziso echipfuramabwe uye haina kukuvara

5. Rovedza timu yako - ita kuti ma riggers azive kurambidzwa pakubatanidza mafundo

Lishenflex inogadzira polyester flat slings kune EN 1492-1 uye ASME B30.9 zviyero, zvine mavara akajeka ane mavara-coded simba mamark uye anotakura-kutakura stitching. Isu tinopawo rigging Hardware-kusanganisira cheni uye majoini-akagadzirirwa akachengeteka sling yekubatanidza.

Kana iwe uchida rubatsiro kusarudza iyo yakakodzera yekubatanidza Hardware yekusimudza mashandiro ako-kana uchida rubatsiro kuona nzira yakakodzera yekuwedzera kureba kwechipfuramabwe-ndokumbira tumira email kune sales@lishenflex.com , uye timu yedu yehunyanzvi ichapa rutsigiro rwemunhu-pamwe.
