Ndingajoyina izilingi ezimbini eziFlethi Ndawonye ukwandisa Ubude?

Iqela lokurhweba lilungiselela ilifti. Umthwalo uneenyawo ezili-15 ubude, kodwa kuphela isilingi esicaba esikhoyo ziinyawo ezili-10. Umphathi ufuna isilingi eside-kwaye ngokukhawuleza. Isilingo sokudibanisa nje izilingi ezimbini ezimfutshane kunye phantse asinakuthintelwa.

Kodwa umphathi wezobuchwephesha uyazi ngcono. Ngokutsho kwe -OSHA 1910.184(c) (2) , nanini na xa kusetyenziswa nayiphi na i-sling, izilingi aziyi kufinyezwa ngamaqhina okanye iibholiti okanye ezinye izixhobo zokuzenzela. I-ASME B30.9 ngokufanayo ifuna ukuba izilingi zingajijwa, zifinyezwe, zibe nde, zibotshelelwe kumaqhina, okanye zidityaniswe ngokuqhina.

I-Lishenflex ibisenza izilingi ezisicaba zokwenziwa amashumi eminyaka, kwaye amava ethu entsimi abonisa ukuba ukudityaniswa kwesilingi ngokungafanelekanga ngoyena nobangela uphambili wokurhwaphiliza . Isenzo esilula sokubopha izilingi ezimbini kunye sinokunciphisa amandla nge-50% okanye ngaphezulu, ukudala indawo yokungaphumeleli eyintlekele phantsi komthwalo.

1. Kutheni Ukujoyina i-Slings ngokuthe ngqo kuyingozi

1.1 Amaqhina kunye ne-Girth Hitches-Ukunciphisa Amandla Amandla

Eyona ndlela iqhelekileyo yokudibanisa izilingi ezimbini liqhina okanye i -hitch girth (unyawo lwelark). Zombini iindlela zenza ukugoba okubukhali okugxininisa uxinzelelo kwindawo encinci. Ngokovavanyo olubhekiselele kuluntu olunyukayo lwase-UK, i-girth hitch inokunciphisa amandla esilingi malunga ne- 50% . Naphantsi kokuPhakanyiswa kweMisebenzi kunye neMimiselo yokuPhakamisa kweZixhobo (LOLER), ukunciphisa ubuncinane i-20% xa kwenziwa ngee-slings ezinobubanzi obulinganayo.

I-SpanSet ilumkisa ukuba naluphi na uhlobo lwesilingi-i-webbing sling, isilingi esingqukuva, intambo yocingo, ityathanga-akufunekanga iqhinwe. Ukubopha iqhina kuya kubangela ukuba iindawo ezinamaqhina zisikekele enye kwenye kwaye ibangele umonakalo, onokuthi ekugqibeleni ubangele ingozi ebulalayo.

1.2 'I-Pulley Effect' kunye nesenzo sokusika

Xa ii-slings ezimbini zidibeneyo kwaye zibekwe phantsi komthwalo, indawo yokudibanisa yenza njenge-pulley. Izilingi zihamba ngokuchasene enye kwenye phantsi koxinzelelo oluphezulu, zidala ukungqubana kunye nokusika isenzo esinokuqhawula imicu. I-SpanSet ichaza ngokucacileyo ukuba izilingi ezinamaqhina zibangela ukuba iindawo zinqumle omnye komnye, zidale umonakalo onokuthi ekugqibeleni ubangele ingozi ebulalayo. Yiyo loo nto i-OSHA kunye nemigangatho ye-ASME ithintela ukujoyina ngokuqhina-umonakalo uqhubela phambili kwaye uhlala ungabonakali kude kube ukusilela.

1.3 IMigangatho yoShishino iyakwalela

Ngokwe- WAC 296-155-55825 , abaqeshi akufuneki banciphise okanye bandise izilingi ngokudibanisa okanye ukujija. Oku kusebenza kwizilingi zewebhu zokwenziwa ngokukodwa. Phantsi kwe -ASME B30.9 , amaqhina kuyo nayiphi na indawo yesilingi zizizathu zokususwa kwangoko enkonzweni. Oku kuthetha ukuba isilingi esibotshiweyo—nokuba kube kanye—sifanele sihlulwe.

Isikhokelo sohlolo seMazzella Companies sidwelisa 'amaqhina kuyo nayiphi na indawo yesilingi' njengemeko efuna ukususwa enkonzweni, kwaye sikwachaza nokuba izilingi azisayi kusonteka, zibotshelelwe kumaqhina, okanye kudityaniswe ngokuqhina. Ngokufanayo, i -Lifting Operations kunye neMimiselo yokuPhakamisa kweZixhobo (LOLER) iyakwenqabela i-knotting njengendlela yokunciphisa okanye ukudibanisa i-slings.

2. Oko Kuthethwa yiMigangatho

3. Indlela eLungileyo yokwandisa ubude be-Sling

Ukuba izilingi ezimbini ezisicaba kufuneka zidityaniswe ukufikelela ubude obufunekayo, ekuphela kwendlela ekhuselekileyo kukusebenzisa izixhobo zokuphakamisa ezizinikeleyo.

3.1 Amakhamandela

Amakhamandela yeyona ndlela ixhaphakileyo yokudibanisa izilingi. Iliso ngalinye le-sling lincanyathiselwe kwipini ye-shackle okanye isaphetha, ukudala indawo yokudibanisa elinganiselwe ngumthwalo. I-EN 1492-1 ixela ukuba izilingi ezilukiweyo ezisicaba zinokusetyenziswa kunye nokufakwa, ngaphandle kokuba izifakelo zilinganiselwe ngokufanelekileyo kwaye ziyahambelana nesilingi.

Iimfuno eziphambili xa usebenzisa amakhamandela :

• Ityayile i-WLL kufuneka ilingane okanye igqithe kwi-WLL yesilingi

• Ubungakanani bekhama kufuneka bulingane amehlo esilingi ngaphandle kokubopha

• Iphini yekhonkco kufuneka iqiniswe ngokufanelekileyo kwaye ikhuseleke

3.2 Iihuku zeeJoker kunye neziQhagamshelwano ezizinikeleyo

I-SpanSet icebisa i -Joker Hook njengenye indlela ekhuselekileyo yokwandisa ubude besilingi. I-Joker Hook isebenza njengesidibanisi sokudibanisa ukudibanisa ubude obubini bee-slings ezijikelezayo okanye i-webbing slings kunye, ekuvumela ukuba wenze isilingi eside xa kufuneka. Inokuphakamisa umthamo, iikhowudi zemibala, kwaye iyahambelana nemigangatho ye-EN 1492.

3.3 Uqhagamshelo oluthambileyo (Xa luvunyelwe)

I-Liftex kunye nabanye abavelisi bavumela uxhulumaniso oluthambileyo kuphela xa uqhagamshelo lwenziwe kwi-hardware elinganiswe ngokufanelekileyo-kungekhona ngokuthe ngqo kwi-sling-to-sling. Umgangatho waseTshayina we -GB/T 25854 ngokufanayo ufuna ukuba zonke iinxalenye zokudibanisa zilinganiswe kwaye zihambelane ne-sling's WLL, kwaye zonke iindawo kufuneka zihlolwe ukunxiba kunye nokonakala ngaphambi kokusetyenziswa.

4. Kwenzeka ntoni xa usebenzisa iKnotted Sling?

• Isilingi kufuneka sicinywe : Ngokwe-ASME B30.9, amaqhina afuna ukususwa enkonzweni.

• Izicatshulwa ze-OSHA : I-OSHA ihlala ikhankanya abaqeshi ngokusebenzisa izilingi ezinamaqhina. Ubuncinci kwityala elinye elibhaliweyo, kukhutshwe isilingi sewebhu sokwenziwa esasibotshelelwe kwiqhina.

• Ukunciphisa amandla : I-hitch ye-girth inciphisa amandla nge-20-50%, kuxhomekeke kwindlela yokudibanisa.

• Umngcipheko wokungaphumeleli kwentlekele : Ukukhuhlana kunye nesenzo sokusika kwiqhina kunokubangela ukusilela ngesiquphe phantsi komthwalo.

5. Isishwankathelo kunye neeNgcebiso eziSebenzayo

Ukudibanisa ii-slings ezimbini ezicwangcisiweyo nge-knotting okanye i-girth hitching inqatshelwe yi-OSHA, ASME, EN 1492-1, kunye ne-LOLER . Ukuziqhelanisa kunciphisa amandla e-sling nge-20-50%, kudala umonakalo oqhubekayo kwingxabano, kwaye ibeka abaqhubi kwingozi enkulu yokusilela.

Izinto eziphambili ezithathwayo:

1. Ungaze iqhina okanye igirth-hitch slings kunye -ithintelwe yimigangatho emininzi kwaye inciphisa amandla kakhulu

2. Sebenzisa i-hardware ezinikeleyo -i-chackles, i-Joker Hooks, okanye ezinye iziqhagamshelo ezinomthwalo womthwalo kuphela iindlela ezikhuselekileyo

3. Amanqaku omdlalo -zonke iihardware eziqhagamshelayo kufuneka zibe ne-WLL elingana okanye enkulu kune-WLL yesilingi

4. Hlola unxibelelwano —jonga ukuba izinto zekhompyutha ziyawafanela na amehlo esilingi kwaye azinakonakala

5. Qeqesha iqela lakho -qinisekisa ukuba zonke iirigger ziyasazi isithintelo kunxibelelwano olunamaqhina

I-Lishenflex yenza i-polyester flat slings ukuya kwi-EN 1492-1 kunye nemigangatho ye-ASME B30.9, kunye neempawu ezicacileyo ezinombala ocacileyo kunye nokuthungwa komthwalo. Sikwabonelela nge-hardware yokurhwaphiliza-kuquka amakhamandela kunye neziqhagamshelo-ezenzelwe ukudityaniswa okukhuselekileyo kwesilingi.
