I-Master Links kanye ne-Master Link Assemblies yizingxenye ezibalulekile zokwakhiwaizihlilingi zokuphakamisa imilenze eminingi.Nakuba ekhiqizwa ngokuyinhloko njengengxenye ye-chain sling asetshenziselwa zonke izinhlobo zezihlilingi ezihlanganisa izihlilingi zezintambo zocingo kanye nezihlilingi zewebhu.
Ukukhetha izixhumanisi eziyinhloko ezilungile nezihambisanayo akuqondile nokho.Kunezinhlobonhlobo ezinhle zezingxenye zesihlilingi esingase sifune ukuzixhuma kuyilapho izindinganiso nezinqubo zihluka kahle - ngakho-ke kuyasiza ukuxoxa ngezinye zezinkinga nezikhombi.
Yini i-Master Link?
I-Master Links kanye ne-Master Link Assemblies nazo zaziwa ngamanye amagama ahlanganisa izixhumanisi ezi-oblong, izindandatho zekhanda, imihlangano yezixhumanisi eziyinhloko eziningi njll. Zingenye yezinhlobo ezindala kakhulu ze-forged lifting tackle futhi zihlala phezulu kwezihlilingi zokuphakamisa imilenze eminingi.
Izihlilingi zokuphakamisa imilenze eminingi zingabaluleka kakhulu ekusabalaliseni amandla okuphakamisa kanye nokuzuza ukuzinza nokulawula umthwalo okhokhelwayo esifuna ukuwuphakamisa.Inkinga esemqoka nokho ukuthiizihlilingifuthi izingxenye zendwayimane zenzelwe indawo eyodwa yokuxhuma ukuthi ithwale umthwalo.Uma sinemilenze emibili, emithathu noma emine kusihlilingi sethu, ngakho-ke umlenze ngamunye waleyo milenze udinga okuthile okuzowujwayelanisa nendawo yokunamathisela (njengehhuku ye-crane) noma enye into eyamukela umlenze owodwa kuphela ngesikhathi.
Ukuxhumana
Indlela izixhumanisi eziyinhloko ezifinyelela ngayo ukuxhumana ibalulekile.
Emilenzeni emibili lokhu kulula, i-Master Link ilinganiselwe ngokuxhumanisa izihlilingi ezimbili ekugcineni kwayo engezansi:
Ngendwayimane yemilenze emine, lokhu nakho kulula.Ukuxhuma imilenze elayishiwe emine ekupheleni kwesixhumanisi esiyinhloko akuvunyelwe, kodwa ngokusebenzisa i-Master Link Assembly (Isixhumanisi Esiyinhloko Esiningi) singaphindaphinda kabili ngokubili ukuze sithole imilenze emine:
Imilenze emithathu iyinkimbinkimbi.Eminye imibhalo emidala ingase ibonise imilenze emithathu ibe isixhumanisi esisodwa, nokho, lokhu manje sekunqatshelwe.Indlela efanele iwukusebenzisa indlela efanayo nokuhlelwa kwemilenze emine futhi usebenzise indwayimane eyodwa kuphela kweziphakathi.
Izihlilingi Ezimbili Ezinemilenze Emibili
Imithwalo Emine Yezihlilingi Ezinemilenze
Ukulayishwa Kwezihlilingi Ezintathu
Umkhawulo Womthwalo Osebenzayo
Singase sibheke izithombe ezingenhla bese sicabanga ukuthi ukuphila kulula - kodwa akusheshi kangako!
Yimuphi Umkhawulo Womthwalo Wokusebenza (WLL) okudingeka siwubheke?
Lokhu mhlawumbe kungokokuqala kweziningi zezinkinga esizobhekana nazo.
Ngesihlilingi semilenze eminingi kufanele siqinisekise ukuthi yonke imilenze yesihlilingi kanye ne-Master Link ine-WLL eyanele yomsebenzi.Singakhetha izingxenye ngendlela eyodwa kwezimbili - singakhetha imilenze esiyidingayo kuqala, bese sikhetha Isixhumanisi Esiyinhloko esizohambisana nayo - noma singakhetha i-Master Link kuqala, bese sithola imilenze yendwayimane enamandla anele alinganisiwe.
Ukwenza lesi sibalo kufanele siqale sazi i-engeli ye-sling.
E-Australia lokhu kuzoba i-engeli efakiwe phakathi kwemilenze ye-sling, futhi i-WLL ephezulu esingayabela izobalwa ngamadigri angu-60.
I-Australian Standard Sling Angle yokubala ubuningi be-WLL.
Ukuba nesilinganiso esingu-60° esitholakalayo kithi kungaba usizo kakhulu ngoba kusiza ukukhulisa amandla anamandla nokuba wusizo kwezihlilingi zethu.
Kukhona okubanjwayo nokho - futhi lelo izinga elivamile laseYurophu (izinga le-EN) .
I-European Standard Chain Sling Angles yokubala ubuningi be-WLL.
Lapha i-engeli ikalwa ukusuka mpo, futhi leyo akuyona inkinga enjalo – kodwa ubukhulu be-WLL bubalwa ku-45° okulingana nobubanzi be-engeli obuhlanganisiwe obungu-90° base-Australia.Ngamafuphi, kusho ukuthi kusayizi onikeziwe weketango, ubukhulu be-WLL besihlilingi kanye nesixhumanisi esiyinhloko esihambisanayo buncane.
Ku-engeli efakwe isihlilingi engu-60°, isixhumanisi esiyinhloko esithi WLL kufanele okungenani sibe izikhathi ezingu-1.73 kunomlenze othi WLL.
Ku-engeli yesihlilingi efakiwe engu-45°, isixhumanisi esiyinhloko esithi WLL kufanele okungenani sibe izikhathi ezingu-1.41 kunomlenze othi WLL.
Kusho futhi ukuthi ukukhethwa kwemikhiqizo nokuhambisana okusohlwini lwase-Europe akuvumelekile e-Australia.
Layisha Yabelana
Izihlilingi ezinemilenze emine zakha iphiramidi.Lokhu kulula ngoba imithwalo eminingi ekhokhelwayo inonxande - kodwa inenkinga engokwemvelo futhi lokho kuwukunganqumi okumile.Kalula nje, imilenze ayihlanganisi umthwalo ngokulinganayo.
Eqinisweni, kunokubheja okukodwa kuphela okuqinisekile uma kuziwa ekulayisheni isabelo futhi lokho kuwusayizi wezingxenye sengathi zabelana ngomthwalo emilenzeni emibili kuphela... yilokho okwenziwa yi-Australian Standards - futhi singenza izivivinyo ezibonisa ukuthi kuwumkhuba ohlakaniphile. .
Okushiwo ngomhlangano wethu wesixhumanisi oMkhulu nokho ukuthi kokubili isixhumanisi esiyinhloko nezixhumanisi ezingezansi ezimaphakathi kufanele zihlangabezane nenani elincane le-WLL lomhlangano uma kubhekwa emilenzeni emibili.
Ngokwe-AS3775 lokhu kusho:
Izidingo Zomhlangano We-Australian Master Link.
Nalapha, imithetho yaseYurophu iyahluka.Abakuvumelayo wukulinganisa izihlilingi ezine zemilenze emilenzeni emithathu.Impela isihlilingi semilenze emine asikwazi ukuzisekela ngokwaso emilenzeni emithathu - kuyindlela esekelwe ezinombolweni kuphela.
Lokhu kungenye yalezo zinto ngezinye izikhathi ezisebenzayo futhi ngezinye izikhathi zingasebenzi.Ezimeni lapho imithwalo ekhokhelwayo iqinile futhi ngezikhathi lapho izilinganiso zesihlilingi zisondela eduze kokwakheka kwephiramidi yangempela isabelo somthwalo phakathi kwemilenze singaba sibi kakhulu futhi isihlilingi kufanele sehliswe ukulinganiswa ukuze kulandelwe imilenze exegayo.
Okushiwo ekukhethweni kwemihlangano ye-Master Link nokho ukuthi uma isixhumanisi esiyinhloko se-WLL sicashunwa njengenani elilodwa phesheya kwezilwandle - lokhu kungasho ukuthi izixhumanisi eziphakathi nendawo aziqinile ngokwanele.
I-European Master Link isebenza kanje:
Lokhu kusebenza namazinga e-EN sling, kodwa akuhambisani ngokwemvelo namazinga ase-Australia.Okubalulekile, akuwona neze ubuwula kumsebenzisi - okungukuthi, ngaphandle uma ukukhethwa komkhiqizo kwenziwe ngokucophelela ukuze kufane nemithetho yesihlilingi ye-AS3775.
I-European Standard Master Link Assemblies ingase idinge ukwehliswa isilinganiso ukuze izixhumanisi ezimaphakathi zibe namandla ngokwanele.
Ukufaka i-Crane Hook
Abasebenzisi abaningi be-sling babhekana nenkinga yokwenza izihlilingi zisebenze ngezingwegwe ze-crane.Kuphakathi kokuthi ihhuku ye-crane incane kakhulu ukuthi ungayiphakamisa - noma i-tackle yokuphakamisa incane kakhulu kuhhuku ye-crane.
Ukuze uhlanganise i-masterlink ku-crane hook, kucelwa ukuqaphela okukhethekile ngezinhlanganisela ezilingana ngokuqinile.
Wonke amahhuku e-crane enziwa ukuthi aqine ekugobeni endizeni eyodwa.Ukwandisa ukusebenza kahle kwamandla basebenzisa i-cross section ejulile kunalokho ebanzi, futhi ekhuluphele ngaphakathi kunangaphandle.
Ihlola ukulingana kwe-Masterlink nehhuku.
Ukugcwala ngokweqile
Sidinga izixhumanisi zethu ukuthi zibe zinde ngokwanele ukuze zilingane nezinto ezifana nezingwegwe ze-crane phezulu kanye nokufakwa phansi - kodwa njengoba sibona ngenhla, ngokuvamile kufanele zibe banzi ngokwanele futhi.
Lokhu akuyona nje imfuneko ye-crane hook.Kuyisidingo sezindawo zokusebenzelana komlenze wendwayimane.
Uma izingxenye zokukhwelana zingakwazi ukuhlala ngokwemvelo kusixhumanisi futhi zithwale imithwalo ngendlela efanele izixhumanisi zigcwele ngokweqile.Lokhu kugcizelela izingxenye ngezindlela ezingavamile futhi akuvunyelwe.
Ukuminyana ngokweqile kungaba yikhanda langempela ikakhulukazi lapho kusetshenziswa i-masterlink ngezihlilingi zezintambo zocingo.
Kuma-slings amancane ukuthola isixhumanisi esinosayizi omuhle kungase kube lula, kodwa uma uxhumano lufika ngamasayizi amakhulu uma lungagcwala kakhulu ngeke lusebenze.
Esibonelweni esisesithombeni inhlanganisela yezintambo ezisindayo ezakhiwe (isithombe esingakwesokudla) ziyaphazamisana futhi azikwazi nje ukuhlala kahle.
Ububanzi
Kuzwakala kulula - ake senze izixhumanisi zibe zikhudlwana.Kodwa ukuba nezixhumanisi ezibanzi kuza ngezindleko.Sisawadinga ama-link ethu ukuze aqine ngokwanele.Ngaphakathi kwemingcele yamandla ensimbi atholakalayo lokhu ngokungaguquguquki kusho izixhumanisi ezikhuluphele ezenziwe ngobubanzi obukhudlwana bezinto ezibonakalayo.Lokhu kungenza kube nzima ukuthola izixhumi ukuthi zilingane.
Izixhumanisi eziningi zinefulethi elicindezelwe ukusiza ngokubandakanya isixhumi seketango.Kubalulekile ukuhlola ubukhulu bomlomo wesixhumi kanye nobubanzi bangaphakathi uma ufuna ukuhlola ukuthi ilingana yini nento efana ne-masterlink noma iketango.
Ukusebenzisa isixhumanisi esinefulethi elicindezelwe ukuthuthukisa ukuhambisana.
Amandla
Kodwa i-masterlink kufanele ibe namandla kangakanani?Ngaphansi kwezindinganiso zase-Australian isihlilingi i-masterlink yanoma isiphi isihlilingi* kufanele sibe nesici somthwalo esiphukayo esingu-4:1 – esifana ncamashi naso esisebenza kumaketango amalilingi.
Lokhu kungakhathaliseki ukuthi isiphi isici somthwalo esiphukayo sezinhlobo ezihlukahlukene zemilenze yendwayimana: Iketango, Intambo Yocingo, I-Round-sling, I-Webbing, njll. Izici ezidingekayo zokuphulwa komthwalo wezihlilingi, kungaba 5, 7, noma ngaphezulu zigcinwe ukuze ubuthakathaka obuhlukahlukene bezinto ezibonakalayo buyacatshangelwa.Lokhu akuthinti ngokuqondile ukufakwa kweketango elifakiwe, ngakho-ke isici sazo somthwalo esiphukayo sihlala sinjengoba bekunjalo ngesilingi seketango.
Lokhu akunjalo kwamanye amazwe nokho, futhi imithetho yendawo kufanele ilandelwe.
* Kukhona okuthile okuhlukile, isici somthwalo esiphukayo saso sonke isihlilingi sabasebenzi abaphethe ibhokisi lokusebenzela le-crane siphindwe kabili, ngakho isixhumanisi esingaba ngu-4:1 singu-8:1 uma silungiselelwe ibhokisi lokusebenza.
Kukhona okwengeziwe ngakho Yebo.Noma iyiphi i-masterlink kufanele ibe i-ductile, kufanele ibhekane nempilo evamile yokusebenza kwesihlilingi, futhi kufanele isinde ekuhlolweni kobufakazi.
I-chain sling ene-Master Link embhedeni wokuhlola
Okubalulekile - ama-masterlink awalayishwa ngawodwana ubufakazi kuze kube senziwe isihlilingi esihlolwe ubufakazi.Ezingeni lokunikezwa kwengxenye masterlinks isampula kuphela ihlolwe phezu mandrels.
Ukuhlolwa kobufakazi kuyingxenye ebalulekile yokwenza izihlilingi ezinokwethenjelwa.Kunezinhlobonhlobo zezingxenye ezihlangana ndawonye kangangokuthi ukuhlola kunikeza isiqinisekiso esidingeka kakhulu sokuthi zonke izingxenye zinamandla afaniswe ne-WLL emakiwe - futhi zizosinda ebunzimeni bokusetshenziswa ngaphandle kokonakala.
Ukuhlola futhi kuvikela ngokumelene nokukhubazeka kwengxenye.
I-Masterlink enenkinga yokukhiqiza itholwe ekulayishweni kobufakazi.
Okuyisisekelo
Okuyisisekelo
I-Master Links iyingxenye ebalulekile uma kuziwa ekugebheni i-lift phezulu njengoba iyindawo yokuxhumana yamaketanga kanye nokusetshenziswa kwezinye izinhlobo ze-sling.
Izincwadi eziphelele zingabhalwa mayelana nama-masterlinks futhi sikwazi kuphela ukuthinta ezinye zezinto eziyisisekelo lapha:
• Izixhumanisi eziyinhloko zezihlilingi zemilenze eminingi kufanele zimiswe ngendlela efanele
• Ukwehluka kwamazinga nezilinganiso kufanele kubhekwe lapho kukhethwa izingxenye
• Kumelwe zihambisane kahle nezihlilingi namahhuku.
• Kumele abe namandla ngokwanele.
…futhi okungenani, kufanele sibheke umaka ofanayo nesitifiketi sokuhlola sobufakazi sezixhumanisi eziyinhloko ezilethwa njengengxenye yokuhlanganiswa kwesihlilingi.
Ama-masterlink amahle kuphela njengokwenziwa kwawo, ukusetshenziswa kwawo kanye nokuhlolwa okuqhubekayo.
Kufanele ngaso sonke isikhathi zikhethwe futhi zihlolwe ngumuntu onekhono.
