Ii-Master Links kunye nee-Master Link Assemblies zizinto ezibalulekileyo ekubunjweniizilingi zokuphakamisa imilenze emininzi.Nangona ikakhulu zenziwe njengecandelo le-chain sling, zisetyenziselwa zonke iintlobo ze-slings kuquka i-wire rope slings kunye ne-webbing slings.
Ukukhetha ii-master links ezichanekileyo nezihambelanayo akulula kangako. Kukho iintlobo ngeentlobo zee-chain sling components esinokufuna ukuzidibanisa ngelixa imigangatho kunye neendlela zokusebenza zahlukile kakuhle - ngoko ke kuyanceda ukuxoxa ngeminye yemiba kunye neengcebiso.
Yintoni i-Master Link?
Ii-Master Links kunye nee-Master Link Assemblies zikwaziwa ngamanye amagama aquka ii-oblong links, ii-head rings, ii-multi-master link assemblies njl. Zezinye zezona ntlobo zindala ze-forged lifting tackle kwaye ziphezulu kwii-multi-leg lifting slings.
Izilingi zokuphakamisa imilenze emininzi zinokuba luncedo kakhulu ekusasazeni amandla okuphakamisa kunye nokufezekisa uzinzo kunye nolawulo lomthwalo esifuna ukuwuphakamisa. Nangona kunjalo, ingxaki esisiseko kukubaizilingikwaye izinto ezisetyenziswa kwi-sling zenzelwe indawo enye yokudibanisa ukuze ithwale umthwalo. Ukuba sinemilenze emibini, emithathu okanye emine kwi-sling yethu, ngoko nganye yaloo milenze ifuna into yokuyilungelelanisa nendawo yokuncamathisela (njenge-crane hook) okanye enye into edibanisa umlenze omnye ngexesha.
Uqhagamshelo
Indlela amakhonkco e-master afikelela ngayo kunxibelelwano ibalulekile.
Kwi-sling yemilenze emibini oku kulula kakhulu, i-Master Link inikwe umlinganiselo wokunxibelelana kwe-sling ukuya kuthi ga kwisibini esisezantsi:
Kwisilingi esinemilenze emine, oku kulula kakhulu. Ukudibanisa imilenze emine ethwele umthwalo esiphelweni sekhonkco eliphambili akuvumelekanga, kodwa ukusebenzisaIndibano yeQhagamshelo eliPhambili(Ikhonkco le-Multi-Master) singaphinda-phinda kabini kabini ukuze sifumane imilenze emine:
Imilenze emithathu inzima ngakumbi. Amanye amaxwebhu amadala anokubonisa imilenze emithathu kwikhonkco elinye, nangona kunjalo, oku ngoku akuvumelekanga ngokubanzi. Indlela efanelekileyo kukusebenzisa indlela efanayo nolungiselelo lwemilenze emine kwaye usebenzise isilingi esinye kuphela kwenye yeendawo eziphakathi.

Umda woMthwalo wokusebenza
Sisenokujonga imifanekiso engasentla size sicinge ukuba ubomi bulula – kodwa hayi ngokukhawuleza kangaka!
Nguwuphi uMda woMthwalo woMsebenzi (i-WLL) ekufuneka siwujonge?
Mhlawumbi le yeyona ngxaki yokuqala kwezininzi esiza kujongana nazo.
Ngesilingi esinemilenze emininzi kufuneka siqinisekise ukuba yonke imilenze yesilingi kunye ne-Master Link ine-WLL eyaneleyo yomsebenzi. Singakhetha izinto ngeendlela ezimbini - singakhetha imilenze esiyidingayo kuqala, emva koko sikhethe i-Master Link ehambelanayo - okanye singakhetha i-Master Link kuqala, size sifumane imilenze yesilingi enezinga elaneleyo.
Ukuze senze olu balo kufuneka siqale sazi i-engile yesilingi.
E-Australia le yi-engile ebandakanyiweyo phakathi kwemilenze yesilingi, kwaye i-WLL ephezulu esinokuyinika iya kubalwa kwi-60 degrees.
I-Angle yeSling esemgangathweni yase-Australia yokubala i-WLL ephezulu.
Ukuba nereyithingi ye-60° esiyifumanayo kunokuba luncedo kakhulu kuba kunceda ukwandisa amandla anokubakho kunye nokusebenza kakuhle kweesling zethu.
Kukho into ebambekayo nangona kunjalo – kwaye leyo yimigangatho yaseYurophu eqhelekileyo (umgangatho we-EN).
Ii-Angles ze-European Standard Chain Sling zokubala i-WLL ephezulu.
Apha i-engile ilinganiswa ukusuka ngokuthe nkqo, kwaye oko akuyongxaki kangako – kodwa i-WLL ephezulu ibalwa kwi-45° elingana noluhlu lwee-engile ezibandakanyiweyo zase-Australia ezingama-90°. Ngamafutshane, kuthetha ukuba kubungakanani obunikiweyo betsheyini, i-WLL ephezulu yesling kunye neye-master link ehambelanayo incinci.
Kwi-engile yesilingi ebandakanyiweyo ye-60°, i-master link WLL kufuneka ibe ubuncinane izihlandlo ezili-1.73 kune-leg WLL.
Kwi-engile yesilingi ebandakanyiweyo ye-45°, i-master link WLL kufuneka ibe ubuncinane ngokuphindwe kayi-1.41 kune-leg WLL.
Kwakhona kuthetha ukuba ukukhethwa kwemveliso kunye nokuhambelana kwayo okudweliswe eYurophu akulunganga e-Australia.
Layisha Ukwabelana
Izilingi ezinemilenze emine zenza iphiramidi. Oku kulula kuba imithwalo emininzi imile okwengxande – kodwa inengxaki yayo kwaye yimeko yokungaguquguquki. Ngamafutshane, imilenze ayibelani ngokulinganayo ngomthwalo.
Enyanisweni, kukho ubhejo olunye kuphela oluqinisekileyo xa kufikwa kulwabiwo lomthwalo kwaye oko kubungakanani bezinto ngokungathi zabelana ngomthwalo ngemilenze emibini kuphela... yiloo nto eyenziwa yi-Australian Standards - kwaye singenza uvavanyo olubonisa ukuba yindlela yobulumko.
Oko kuthetha ukuba kwi-Master link assembly yethu kukuba zombini i-master link ephezulu kunye ne-intermediate links ezisezantsi kufuneka zihlangabezane ne-WLL encinci ye-assembly ukuba zijongwa ngemilenze emibini.
Ngokwe-AS3775 oku kuthetha ukuba:
Iimfuneko zeNdibano ye-Master Link yase-Australia.
Kwakhona, imithetho yaseYurophu yahlukile. Oko bakuvumelayo kukubeka amanqaku kwiislings ezine zemilenze emithathu. Kakade ke, isling yemilenze emine ayinakuzixhasa ngokwasemzimbeni ngemilenze emithathu - yindlela esekelwe kumanani kuphela.
Le yenye yezinto ezithi ngamanye amaxesha zisebenze kwaye ngamanye amaxesha zingasebenzi. Kwimeko apho imithwalo yomthwalo iqinile kwaye ngamaxesha apho imilinganiselo yesilingi isondela kwimo yokwenyani yephiramidi, isabelo somthwalo phakathi kwemilenze sinokuba sibi kakhulu kwaye isilingi kufuneka sincitshiswe ukuze kujongwe imilenze ethe tyaba ephumayo.
Oko kuthetha ukukhethwa kweendibano zeMaster Link kukuba xa i-master link WLL icatshulwe njengexabiso elinye phesheya – oku kunokuthetha ukuba ii-intermediate link azinamandla ngokwaneleyo.
Ikhonkco eliyiNtloko laseYurophu lisebenza ngolu hlobo:
Oku kusebenza kwimigangatho ye-EN sling, kodwa akuhambelananga ngokwendalo neMigangatho yase-Australia. Okubalulekileyo kukuba, ayilunganga kangako kumsebenzisi – oko kukuthi, ngaphandle kokuba ukhetho lwemveliso lwenziwe ngononophelo ukuze luhambelane nemithetho ye-AS3775 sling.
Iindibano ze-European Standard Master Link Assemblies zisenokufuna ukuncitshiswa ukuze ii-intermediate links zibe namandla ngokwaneleyo.
Ukufakela iCrane Hook
Abasebenzisi abaninzi besilingi bajongene nomba wokwenza izilingi zisebenze ngee-crane hooks. Nokuba i-crane hook incinci kakhulu kwi-lift tackle - okanye i-lift tackle incinci kakhulu kwi-crane hook.
Ukuze ufake ikhonkco eliphambili kwi-crane hook, kufuneka kuqatshelwe ngokukodwa xa kudityaniswa izinto ezihambelana kakuhle.
Zonke ii-crane hooks zenzelwe ukuba ziqine xa zigoba kwindawo enye. Ukuze basebenzise amandla amaninzi basebenzisa i-cross section enzulu kunokuba ibanzi, kwaye ityebile ngaphakathi kunangaphandle.
Ukujonga ukuba i-Masterlink kunye ne-hook zifanelekile na.
Ukuxinana kwabantu abaninzi
Sifuna ukuba amakhonkco ethu abe made ngokwaneleyo ukuze alingane nezinto ezifana nee-crane hooks phezulu kunye nee-fittings ezantsi - kodwa njengoko sibona ngasentla, maxa wambi kufuneka abe makhulu ngokwaneleyo.
Oku akupheleli nje ekubeni kubekho i-crane hook, kodwa kuyimfuneko yokuba kubekho i-sling leg interfaces.
Ukuba iindawo zokudibana azikwazi ukuhlala ngokwemvelo kwikhonkco kwaye zithwale imithwalo ngokuchanekileyo, iindawo zokudibana zixinene kakhulu. Oku kugxininisa iindawo ngeendlela ezingaqhelekanga kwaye akuvumelekanga.
Ukuxinana kwabantu kunokuba yingxaki enkulu ingakumbi xa kusetyenziswa i-masterlink kunye neentambo zentambo.
Kwizilayidi ezincinci ukufumana ikhonkco elinobukhulu obuhle kunokuba lula, kodwa xa uqhagamshelo lufika ngobukhulu obukhulu ukuba lunokuxinana aluyi kusebenza.
Kumzekelo okwifoto, indibaniselwano yeethimbles ezenziwe ngobunzima obukhulu (umfanekiso wasekunene) iyaphazamisana kwaye ayikwazi ukuhlala kakuhle.
Ububanzi
Kuvakala kulula – masenze nje amakhonkco abe makhudlwana. Kodwa ukuba namakhonkco abanzi kuza neendleko. Sisafuna amakhonkco ethu abe namandla ngokwaneleyo. Ngaphakathi kwemida yamandla entsimbi ekhoyo oku kuthetha ukuba amakhonkco atyebileyo enziwe ngobubanzi obukhulu bezinto ezibonakalayo. Oku kunokwenza kube nzima ukufumana amakhonkco afanelekileyo.
Iikhonkco ezininzi zine-stain ecinezelweyo ukunceda ekubambeni i-chain connector. Kubalulekile ukujonga ubukhulu bomlomo we-connector kunye nobubanzi bangaphakathi ukuba ufuna ukujonga ukuba iyangena na into efana ne-masterlink okanye i-shackle.
Ukusebenzisa ikhonkco elineflethi ecinezelweyo ukuphucula ukuhambelana.
Amandla
Kodwa i-masterlink ifanele ibe namandla kangakanani? Phantsi kwemigangatho ye-sling yase-Australia, i-masterlink yayo nayiphi na i-sling* kufuneka ibe ne-breaking load factor ye-4:1 - ngendlela efanayo naleyo ifana ngayo ne-chain slings.
Oku kwenzeka nokuba yintoni na into ebangela ukuqhekeka komthwalo kwiintlobo ezahlukeneyo zemilenze yesilingi: Itsheyini, Intambo yocingo, I-Round-sling, I-Webbing, njl. Izinto ezifunekayo ezibangela ukuqhekeka komthwalo wezilingi, nokuba zi-5, 7, okanye ngaphezulu ziyagcinwa ukuze kuthathelwe ingqalelo ubuthathaka bezinto ezahlukeneyo. Ezi azichaphazeli ngokuthe ngqo izixhobo zetsheyini ezibandakanyiweyo, ngoko ke into ebangela ukuqhekeka komthwalo ihlala injalo kwitsheyini yesilingi.
Oku akunjalo kwamanye amazwe nangona kunjalo, kwaye imithetho yasekuhlaleni kufuneka ithotyelwe.
* Kukho ezinye izinto ezingaqhelekanga, i-breaking load factor ye-sling epheleleyo ye-crene workbox ephethe abasebenzi iphindwe kabini, ngoko ke ikhonkco eliya kuba yi-4:1 yi-8:1 xa lilungiselelwe ibhokisi yokusebenza.
Kukho okungakumbi kuyo ewe. Nayiphi na i-masterlink kufuneka ibe yi-ductile, kufuneka ikwazi ukumelana nobomi obuqhelekileyo bokusebenza kwe-sling, kwaye kufuneka ihlale ixesha elide ivavanywa.
I-chain sling ene-Master Link ebhedini yovavanyo
Okubalulekileyo – ii-masterlinks azifakwanga ubungqina bodwa de zibe zizinto ezivavanywayo. Kwinqanaba lobonelelo lwezixhobo, ii-masterlinks zivavanywa kuphela ngee-mandrels.
Uvavanyo lobungqina luyinxalenye ebalulekileyo yokwenza izilingi ezithembekileyo. Kukho iintlobo ngeentlobo zeendawo ezihambelanayo kangangokuba uvavanyo lubonelela ngesiqinisekiso esifunekayo sokuba zonke iindawo zinamandla afana ne-WLL ephawulweyo - kwaye ziya kusinda kubunzima bokusetyenziswa ngaphandle kokuguquka.
Uvavanyo lukwakhusela kwiziphene zenxalenye.
I-Masterlink enesiphako sokuvelisa esifunyenweyo xa umthwalo wokufaka ubungqina uvaliwe.
Iziseko
Iziseko
Ii-Master Links ziyinxalenye ebalulekileyo xa kufikwa ekulungiseni i-overhead lift njengoko ziyindawo yokudibanisa ii-chain slings kunye nokusetyenziswa kwezinye iintlobo ze-sling.
Iincwadi ezipheleleyo zingabhalwa malunga nee-masterlinks kwaye singakwazi ukuchukumisa ezinye zezona zinto zisisiseko apha:
• Iikhonkco eziphambili zee-slings zemilenze emininzi kufuneka zicwangciswe ngokuchanekileyo
