Nshobora gukoresha Flat Sling muburyo bwa Choke Hitch?

Abakozi babigenewe bakeneye kuzamura umutwaro wa silindrike - umuyoboro wibyuma, inkingi ya beto, cyangwa umugozi wa rebar. Uwiteka umugozi  uringaniye bafata kuri rack nuburebure bukwiye nubushobozi. Ariko umutwaro ntusobanura ingingo zifatika. Igikoresho kizengurutsa umugozi uzengurutse umutwaro, kinyura mu jisho rimwe mu rindi, kandi kiragikomera. Iki nikiniga - kandi gishobora kuba igisubizo cyiza, ariko mugihe bikozwe neza.

 

Lishenflex  imaze imyaka irenga makumyabiri ikora ibishushanyo mbonera bya synthique, kandi uburambe bwumurima wacu bwerekana ko gufata choke biri mubintu byakoreshejwe nabi cyane. Indwara ya choke igaragara nkiyoroshye, ariko kuyikoresha neza biterwa no gusobanukirwa kugabanya ubushobozi, inguni ikwiye, hamwe nuburyo bwa shitingi. Dukurikije imibare y’inganda  zakozwe na EN 1492-1 zubahiriza uruganda rukora imipira, ubushobozi bwa choke ni 0.8 - bivuze ko umugozi wagenwe kuri toni 1 muri lift ihagaritse ushobora gutwara gusa kg 800 mumatongo.

 

Indwara ya Choke ni iki?

Kuniga kunanirwa ni ibishushanyo mbonera aho umugozi uzengurutswe n'umutwaro, kandi impera imwe ya shitingi inyuzwa mu jisho ritandukanye cyangwa rikwiranye. Umutwaro uhita uzamurwa, bigatuma umugozi ukomera hafi yumutwaro. Ibi birema ingaruka zifatika  zituma umutwaro urinda kunyerera.

 

Nkuko byasobanuwe mubuyobozi bwa OSHA kubijyanye no gukoresha Sling Safe , hiteri ya choker ikwiranye n'imizigo igoye kuringaniza cyangwa umutekano hamwe na lift igororotse. Choker hit itwara umutwaro neza mukuzenguruka. Ariko, OSHA iraburira mu buryo bweruye ko mugihe cyo kuniga, ingingo ya choke igomba kuba kumubiri wa shitingi gusa, ntizigere igabanywa cyangwa ikwiye.

 

Ikigo  cya Rigging Institute  kivuga ko icyuma cya choke ari kimwe mu bintu bitatu by'ibanze bya shitingi, hamwe na vertical na basket, kandi bikunze gukoreshwa mugihe umutwaro udafite aho uhurira.

 

Kugabanya ubushobozi muri Choke Hitch

Ikintu gikomeye cyane mugukoresha choke hit ni kugabanya ubushobozi. Urupapuro rwerekana akazi ntarengwa ni murwego rwo hejuru. Iyo ikoreshejwe mukuniga, ubushobozi buragabanuka cyane.

 

Dukurikije amabwiriza ya OSHA yerekeranye no gukoresha Sling Safe , umutwaro wagenwe ku mugozi mu mwobo wa choke ugenwa n’uruganda rukora imashini kandi rushingiye ku mfuruka ya choke. OSHA ivuga ko ubushobozi bwa choke bushobora gukoreshwa mugihe inguni ya choke ari dogere 120 cyangwa zirenga. Ku mfuruka ya choke iri munsi ya dogere 120, umutwaro wagenwe ugomba kugabanuka cyane ukurikije ibyifuzo byuwakoze sling.

 

Imbonerahamwe yo kugereranya ubushobozi (ishingiye kuri EN 1492-1 polyester igororotse):

 

Inkomoko: EN 1492-1 amakuru yubushobozi kuva CEREX na Mennens

 

Nkuko imbonerahamwe ibigaragaza, ibintu bya choke (KL) ni 0.8 munsi ya EN 1492-1, byerekana kugabanuka kwa 20% ugereranije no guhagarikwa.

 

Ni ryari Indwara ya Choke ikwiye?

Indwara ya choke irakwiriye mubihe byihariye:

 

1.Imizigo idafite ingingo zomugereka zisobanutse - imitwaro ya silindrike, imiyoboro, imigozi ya rebar, hamwe ninkingi zifatika

 

2.Imizigo ikeneye gufatwa neza - kwirinda kunyerera mugihe cyo guterura cyangwa kuzunguruka

 

3.Guterura ukuguru-kuguru -ahantu hose igitebo ntigishoboka

 

Nkuko byagaragajwe na Medeer Lifting , icyuma cya choke ni ingirakamaro mu gufata imizigo neza ariko ntigifite umutekano uhagaze neza kandi gishobora kwangiza umugozi iyo gikoreshejwe nabi. Gusa imigozi yagenewe gukoreshwa ya choke igomba gukoreshwa muriyi miterere, kandi shitingi igomba kugenzurwa ibyangiritse mbere na nyuma yo gukoreshwa.

 

Imyitozo myiza:  Mugihe cyo kuniga, ingingo ya choke igomba guhagarikwa kumubiri wa shitingi - ntizigera ijisho, gucamo ibice, cyangwa bikwiye. Inguni ya choke igomba kuba 120 ° cyangwa irenga kugirango igumane ibintu byose 0.8.

 

Ibitekerezo byingenzi byumutekano

Ntugakoreshe igikoma niba:

 

Sling Igiti gifite gukata, gukuramo, cyangwa kudoda kwangirika muri kariya gace kazabyara

 

Inguni ya choke iri munsi ya 120 ° nta kugabanya ubushobozi bujyanye

 

● Umutwaro ufite impande zikarishye zishobora guca fibre (koresha inguni)

 

● Urubingo rugoretse cyangwa rufunitse - ibi bitera ingingo zingana zingana

 

Tag Ikiranga cya shitingi kibuze cyangwa kitemewe - ntushobora kugenzura ubushobozi bwagenwe

 

OSHA irabuza mu buryo bweruye:

 

Ingingo zifunitse (kugabanya cyangwa kurambura ipfundo cyangwa kugoreka ntibyemewe)

 

● Using a sling in a choke hitch with the choke point on a splice or fitting

 

Kuruhuka imitwaro kuri shitingi

 

Gukuramo umugozi munsi yumutwaro mugihe umutwaro uhagaze kumurongo

 

Igeragezwa rya laboratoire ya Lishenflex ryemeza ko gutemagura ndetse byangiritse byoroheje - nko gukuramo ibice cyangwa gukata inkombe - uburambe bwihuta kwambara muburyo bwa choke hitch bitewe nimbaraga ziteranijwe kuri choke. Niyo mpamvu mbere yo gukoresha no kugenzura kenshi kuri ASME B30.9 ni ingenzi cyane kubice bikoreshwa mugukata.

 

Ubugenzuzi busabwa kugirango Choke ikoreshwe

Imishumi ikoreshwa mugace ka choke igomba kugenzurwa kenshi kuruta iyakoreshejwe gusa muri lift ihagaritse. ASME B30.9  isaba inzego eshatu zo kugenzura:

 

Ibipimo byingenzi byo kuvanaho munsi ya ASME B30.9  kubice bisobekeranye bikoreshwa muri choke:

 

● Kumeneka cyangwa kwambara kudoda mubice bitwara imitwaro

 

● Acide cyangwa caustic yaka

 

Ibimenyetso byangiza ubushyuhe

 

● Imyobo cyangwa amarira yerekana imipira yibanze-cyane cyane kuri choke

 

Wear Kwambara birenze urugero

 

Utudodo mu mubiri wa shitingi - birabujijwe gupfundika munsi ya OSHA

 

● Guhindura ibara cyangwa uduce duto twerekana imiti yangiza cyangwa UV

 

Incamake n'ibyifuzo bifatika

Igipande kiringaniye  kirashobora gukoreshwa muburyo bwa choke, ariko porogaramu igomba kwegerwa ubwitonzi nubushobozi.

 

Ibyingenzi byingenzi:

 

1. Kugabanya ubushobozi ntibishobora kuganirwaho -kuniga kugabanuka kugabanya WLL kugera kuri 80% yubushobozi bwa vertical munsi ya EN 1492-1

 

2.Kora inguni zingirakamaro - gumana 120 ° cyangwa irenga kubintu 0.8 byuzuye; gabanya ubushobozi kumpande ntoya kubayobora

 

3.Ntukigere uniga igice cyangwa gikwiye - ingingo ya choke igomba kuba kumubiri

 

4.Tekereza mbere na nyuma yo gukoreshwa - gufata ibyemezo byibanda ku guhangayika; reba ibyangiritse byaho

 

5.Koresha kurinda inguni -kumutwaro ufite impande zikarishye

 

Lishenflex  ikora amashanyarazi ya polyester ifite amaso ashimangiwe hamwe nibimenyetso byerekana amabara asobanutse neza, yujuje ubuziranenge bwa EN 1492-1 na ASME B30.9. Ibicuruzwa byacu byageragejwe kubintu byose byashizwemo, harimo na choke, kandi turatanga amahugurwa yo kugenzura kugirango dushyigikire umutekano.

 

Niba ukeneye ubufasha bwo kumenya niba ibice byawe bya tekinike bikwiranye na choke hit-cyangwa ukeneye ubuyobozi kubijyanye no kubara ubushobozi bwa geometrie yawe yihariye - nyamuneka ohereza imeri kuri sales@lishenflex.com , hamwe nitsinda ryacu tekinike tuzatanga inkunga kumuntu umwe.
