Xana Ndzi Nga Hlanganisa Swirhendzevutana Swimbirhi Swa Xiphepherhele Swin’we Leswaku Ndzi Engetela Ku Leha?

Vatirhi va rigging va le ku lunghiseleleni ka lift. Ndzhwalo wu lehe timitara ta 15, kambe hi wona ntsena flat sling leyi kumekaka i 10 feet. Mulanguteri u lava xihuku xo leha—naswona u hatlisa. Ndzingo wo hlanganisa ntsena swirhendzevutana swimbirhi swo koma swi le kusuhi ni ku nga siveriwi.

Kambe mulanguteri wa rigging u swi tiva ku antswa. Hi ku ya hi OSHA 1910.184(c)(2) , nkarhi wun’wana na wun’wana loko ku tirhisiwa xirhendzevutani xihi kumbe xihi, swirhendzevutani a swi fanelanga ku hungutiwa hi mafenya kumbe tiboloti kumbe switirhisiwa swin’wana swa nkarhinyana. ASME B30.9 hi ku fanana yi lava leswaku swirhendzevutani swi nga soholotiwi, swi hungutiwa, swi lehisiwa, swi bohiwa swi va mafenya, kumbe ku hlanganisiwa hi ku hlanganisiwa.

Lishenflex yi endle makume ya malembe yi ri karhi yi endla swirhendzevutana leswi endliweke hi swiphepherhele, naswona ntokoto wa hina wa le nsin’wini wu kombisa leswaku ku hlanganisiwa loku nga fanelangiki ka swirhendzevutana i xivangelo lexikulu xa timhangu ta vukanganyisi . Xiendlo xo olova xo boha swirhendzevutani swimbirhi swin’we xinga hunguta matimba hi 50% kumbe kutlula, leswi endlaka leswaku kuva na ndzhawu yo tsandzeka swinene ehansi ka ndzhwalo.

1. Ha Yini Ku Hlanganisa Swirhendzevutana Hi Ku Kongoma Swi Ri Ni Khombo

1.1 Ti-Knot na Girth Hitches—Ku Pfuxetiwa Ka Matimba swinene

Ndlela leyi tolovelekeke yo hlanganisa swirhendzevutani swimbirhi i knot kumbe girth hitch (lark’s foot). Maendlelo lawa hamambirhi ya endla ku gombonyoka loku tlhavaka loku dzikisaka ntshikilelo eka ndhawu leyitsongo. Hikuya hi swikambelo leswi kongomisiweke eka vaaki va UK climbing, girth hitch yinga hunguta matimba ya sling hi kwalomu ka 50% . Hambi kuri ehansi ka Lifting Operations and Lifting Equipment Regulations (LOLER), kuhungutiwa ka kwalomu ka 20% loko ku endliwa hi ti slings ta diameter yo ringana.

SpanSet yi tsundzuxa leswaku muxaka wihi na wihi wa xirhendzevutani—xisirhelelo xa webbing, xirhendzevutani xa xirhendzevutana, ntambhu ya waya, nketani—a wu fanelanga ku hlanganisiwa. Ku boha xikhomo swi ta endla leswaku swiphemu leswi bohiweke swi tsemakanyana ivi swi onha, leswi nga hetelelaka swi vanga mhangu leyi dlayaka.

1.2 'Mbuyelo wa Pulley' na Goza ro Tsema

Loko swirhendzevutana swimbirhi swi hlanganisiwa ivi swi vekiwa ehansi ka ndzhwalo, ndhawu yo hlanganisa yi tirha ku fana ni pulley. Ti slings ti famba ti lwisana ehansi ka tension yale henhla, leswi endlaka leswaku kuva na friction xikan’we naku tsema action leyinga tsema ti fibre. SpanSet yi vula hi ku kongoma leswaku swirhendzevutana leswi hlanganisiweke swi endla leswaku swiphemu swi tsema, leswi endlaka leswaku ku va ni ku onhaka loku nga hetelelaka ku va ni mhangu leyi dlayaka. Leswi hi swona swi endlaka leswaku mimpimanyeto ya OSHA na ASME yi yirisa ku hlanganisa hi ku hlanganisa—ku onhaka ku ya emahlweni naswona hakanyingi a ku vonaki ku kondza ku tsandzeka.

1.3 Swipimelo swa Vumaki Swi Yi Yirisa

Hi ku ya hi WAC 296-155-55825 , vathori a va fanelanga ku pfuxeta kumbe ku lehisa swirhendzevutana hi ku hlanganisa kumbe ku soholota. Leswi swi tirha eka ti synthetic web slings hiku kongoma. Ehansi ka ASME B30.9 , ti knots eka xiphemu xin’wana na xin’wana xa sling i swivangelo swo susiwa hi xihatla eka ntirho. Leswi swi vula leswaku xihuku lexi bohiweke—hambi ku ri kan’we—xi fanele xi mbundzumuxiwa.

Nkongomiso wa ku kambela wa Tikhamphani ta Mazzella wu xaxameta 'ti knots eka xiphemu xihi kumbe xihi xa xirhendzevutani' tanihi xiyimo lexi lavaka ku susiwa eka ntirho, naswona wu ya emahlweni wu vula leswaku swirhendzevutani a swi fanelanga ku soholotiwile, swi bohiwa swi va mafenya, kumbe ku hlanganisiwa hi ku hlanganisiwa. Hilaha ku fanaka, Milawu ya Matirhelo yo Tlakusa na Switirhisiwa swo Tlakusa (LOLER) yi yirisa ku hlanganisa tanihi ndlela yo pfuxeta kumbe ku hlanganisa swirhendzevutani.

2. Leswi Mimpimanyeto Yi Swi Vulaka

3. Ndlela Leyinene Yo Andzisa Ku leha Ka Sling

Loko swirhendzevutana swimbirhi leswi nga ni swiphepherhele swi fanele swi hlanganisiwa leswaku ku fikeleriwa ku leha loku lavekaka, ndlela yin’we ntsena leyi hlayisekeke i ku tirhisa switirhisiwa swo tlakusa leswi tinyiketeleke.

3.1 Swibokisana

Ti shackles i ndlela leyi tolovelekeke swinene yo hlanganisa swirhendzevutani. Tihlo rin’wana na rin’wana ra sling ri khomanisiwile na shackle pin kumbe bow, leswi endlaka leswaku kuva na ndzhawu yo hlanganisa leyi ringaneleke ndzhwalo. EN 1492-1 yi hlamusela leswaku swirhendzevutani swa webbing leswi lukiweke hi xiphepherhele swi nga tirhisiwa na switirhisiwa, ntsena loko switirhisiwa swi ringanisiwile kahle naswona swi fambisana na xirhendzevutani.

Swilaveko swa nkoka loko u tirhisa swihuku : .

• Shackle WLL yifanele ku ringana kumbe ku tlula WLL ya sling

• Vukulu bya shackle byifanele kuringanela mahlo ya sling handle ko boha

• Shackle pin yifanele ku tiyisiwa kahle no khomiwa

3.2 Swikhomo swa Joker na Swihlanganisi leswi Tinyiketeleke

SpanSet yi ringanyeta Joker Hook tani hi ndlela yin’wana leyi hlayisekeke yo engetela ku leha ka sling. Joker Hook yitirha tani hi xihlanganisi xo hlanganisa ku hlanganisa ku leha kambirhi ka swirhendzevutani kumbe swirhendzevutani swa webbing swin’we, leswi pfumelelaka ku endla xirhendzevutani xo leha loko swilaveka. Yina vuswikoti byo tlakusa, tikhodi ta mihlovo, naswona yi fambisana na swipimelo swa EN 1492.

3.3 Swihlanganisi swo olova (Loko swi Pfumeleriwa) .

Liftex na vaendli van’wana va pfumelela ku hlanganisiwa ko olova ntsena loko ku hlanganisiwa ku endliwile eka xitirhisiwa xa hardware lexi ringanyetiweke kahle—ku nga ri hi ku kongoma sling-to-sling. Xiyimo xa China xa GB/T 25854 hi ku fanana xi lava leswaku swiphemu hinkwaswo leswi hlanganisaka swi ringanisiwa naswona swi fambisana na WLL ya sling, naswona swiphemu hinkwaswo swi fanele ku kamberiwa ku vona loko swi onhakile na ku onhaka loko swi nga si tirhisiwa.

4. Ku Humelela Yini Loko U Tirhisa Xirhendzevutana Lexi Nga Ni Mafenya?

• Xirhendzevutani xifanele ku lahliwa : Hi ASME B30.9, ti knots ti lava ku susiwa eka vukorhokeri.

• Swikombo swa OSHA : OSHA yi tshamela ku tshaha vathori hikwalaho ko tirhisa swirhendzevutana leswi hlanganisiweke. Eka nandzu wun’we lowu tsariweke, ku humesiwe xikombelo xa xikombo xa xirhendzevutani xa webu lexi endliweke lexi bohiweke hi xikhomo.

• Kuhungutiwa ka matimba : Girth hitch yihunguta matimba hi 20-50%, kuya hi ndlela yo hlanganisa.

• Khombo ra ku tsandzeka ka khombo : Ku hlangana na ku tsema eka xikhomo swinga vanga ku tsandzeka ka xitshuketa ehansi ka ndzhwalo.

5. Nkatsakanyo na Switsundzuxo leswi Tirhaka

Ku hlanganisa swimbirhi swa xiphepherhele swirhendzevutana hi ku knotting kumbe girth hitching swi yirisiwile hi OSHA, ASME, EN 1492-1, na LOLER . Mukhuva lowu wu hunguta matimba ya sling hi 20-50%, wu endla ku onhaka loku yaka emahlweni kusuka eka friction, naswona wu veka vafambisi ekhombyeni ro tsandzeka ra khombo.

Swilo swa nkoka leswi tekiwaka:

1. U nga tshuki u knot kumbe girth-hitch slings swin’we —swi yirisiwile hi mimpimanyeto yo tala naswona swi hunguta matimba swinene

2. Tirhisa tihardware leti tinyiketeleke —swikhomo, Joker Hooks kumbe swihlanganisi swin’wana leswi ringaniseriweke hi ndzhwalo hi swona ntsena tindlela leti hlayisekeke

3. Swiringanyeto swa ku fambisana —tihardware hinkwato leti hlanganisaka ti fanele ti va na WLL leyi ringanaka kumbe ku tlula WLL ya sling

4. Kambela swihlanganisi —languta leswaku hardware yi ringanela mahlo ya sling naswona a yi onhakanga

5. Dyondzisa ntlawa wa wena —tiyiseka leswaku va- rigger hinkwavo va swi tiva ku yirisiwa ka swihlanganisi leswi hlanganisiweke

Lishenflex yi endla ti polyester flat slings kuya hi EN 1492-1 na ASME B30.9 standards, na swikoweto swa vuswikoti leswi nga erivaleni swa mihlovo na ku rhungela loku rhwalelaka ndzhwalo. Hi tlhela hi nyikela hi switirhisiwa swa rigging—ku katsa ni swikhomo ni swihlanganisi—leswi endleriweke ku hlanganisa swirhendzevutana leswi hlayisekeke.

Loko u lava mpfuneto wo hlawula hardware yo hlanganisa leyi faneleke eka matirhelo ya wena yo tlakusa—kumbe u lava mpfuneto wo kumisisa ndlela leyi faneleke yo engetela ku leha ka xirhendzevutani—hi kombela u rhumela imeyili eka sales@lishenflex.com , naswona ntlawa wa hina wa xithekiniki wu ta nyika nseketelo wa munhu hi xiyexe.
