Izixhumanisi namaringi kuwuhlobo oluyisisekelo lwe-hardware yokuqopha, ehlanganisa nje iluphu yensimbi eyodwa. Mhlawumbe uke wabona indandatho eyinhloko ilele eduze kwesitolo noma isixhumanisi esi-oblong esilenga kuhuku lwe-crane. Kodwa-ke, uma umusha embonini yokugebenga noma ungakaze usebenzise isixhumanisi noma indandatho ngaphambilini, kungase kungacaci kahle ukuthi kungani lezi zixhobo ezilula zibaluleke kangaka lapho uqopha i-lift engaphezulu.
Siqaphele ukuthi uma kukhulunywa ngezixhumanisi namaringi, ulwazi oluningi oluqondile nolwezobuchwepheshe luyatholakala ku-inthanethi. Nokho, ulwazi olujwayelekile lokuthi lawa madivaysi ayini nokuthi asetshenziselwa ini cishe alukho.
Kumakhasimende akhona okungenzeka ukuthi masha emikhiqizweni ehlobene nokukhwabanisela, ukuqala ngolwazi oluyisisekelo nolwazi olusekelwe kuhlelo lokusebenza kuyadingeka ngaphambi kokungena ezintweni eziyinkimbinkimbi kakhulu. Kungakho sibhale lesi sihloko.
Kulesi sihloko, ungalindela ukufunda:
• Yiziphi izixhumanisi nezindandatho nokuthi zisetshenziselwa ini
• Yiziphi izinhlobo ezahlukene zezixhumanisi namaringi
• Izixhumanisi nezimpawu zamaringi / ukuhlonza
• Ukususwa kwezixhumanisi nezindandatho kumibandela yesevisi
1. Yiziphi Izixhumanisi Nezindandatho?
Izixhumanisi namaringi kuyizici eziyisisekelo kodwa ezibalulekile ekuphakamiseni nasekufakeni izinhlelo zokusebenza. Amadivayisi avaliwe-afana neso-asetshenziselwa ukwenza izindawo zokuxhuma emibuthanweni yokugwaza kanye ne-sling kuhlanganise.izihlilingi zamaketanga, izihlilingi zezintambo zocingo, izihlilingi zewebhu, njll.
Izixhumanisi nezindandatho zivame ukusetshenziswa njengendawo yokuxhumaimihlangano ye-multiple-leg sling—imvamisa iketango noma intambo yocingo. Angase asetshenziswe njengendawo yokuxhumana yokucushwa komlenze owodwa, emibili, emithathu, noma emine.
Izixhumanisi eziyinhloko nezindandatho-izixhumanisi eziyinhloko ezi-oblong, izindandatho eziyinhloko, nezixhumanisi eziyinhloko ezimise okwepheya-zibuye zibizwe ngokuthi amandandatho abaqoqi noma izixhumanisi zokuqoqa, njengoba "ziqoqa" imilenze eminingi ye-sling ibe isixhumanisi esisodwa.
Ngaphezu kokusetshenziswa emibuthanweni yezihlilingi, izixhumanisi namaringi kungasetshenziswa futhi njengendawo yokuxhumana phakathi cishe kwanoma yiziphi izingxenye ezimbili zomhlangano wokuhlanganisa. Isibonelo, ungasebenzisa isixhumanisi noma iringi ukuze uxhume:Bopha intambo ku-crane hook,Sling kuhhuku,Xhuma kuhuku lwendwayimana
2. Izinhlobo zezixhumanisi nezindandatho
Kunezinhlobo eziningana ezahlukene zezixhumanisi namaringi angasetshenziswa ekuhlanganiseni. Izinhlobo ezivame ukusetshenziswa kakhulu zezixhumanisi namaringi yilezi:Izixhumanisi ezi-Oblong master,I-Master link sub-assemblies,Izixhumanisi ezimise okwepheya,Izindandatho ezinhle,Izixhumanisi zokuhlanganisa
Izixhumanisi ze-Oblong master nazo zingasetshenziswa ukuxhuma i-shackle ku-crane hook, i-hook ku-shackle, nezinye izinhlangano ezihlukahlukene zokubopha.
Ama-sub-assemblies ahlanganisa izixhumanisi ezimbili eziyinhloko ezixhunywe kusixhumanisi esiyi-oblong master. Kunokuba unamathisele yomine imilenze yezihlilingi kusixhumanisi esiyinhloko, manje ingahlukaniswa phakathi kwezixhumanisi ezimbili ze-sub-assembly.
Ukusetshenziswa kwama-sub-assemblies kusiza ekunciphiseni usayizi wesixhumanisi esiyinhloko—izixhumanisi eziyinhloko ezinkulu kakhulu zingaba phezulu ngamasentimitha angu-3 ububanzi—ngenkathi kugcinwa Umkhawulo Womthwalo Wokusebenza (WLL) oqhathaniswa nesixhumanisi esikhulu kakhulu.
Ukuma kwepheya kwalezi zixhumanisi kuzenza zilungele ukusetshenziswa ngamahhuku amancane kakhulu. Kwezinye izimo, isixhumanisi esimise okwepheya sizolingana ne-oblong master link, eqeda ukunyakaza komthwalo ukusuka ohlangothini kuya ohlangothini ebusweni behuku.
Umumo oyindilinga wendandatho eyinhloko yenza ingabi yinhle kangako kunesixhumanisi esiyi-oblong master sokuxhuma kumahhuku amakhulu, ajulile e-crane. Izindandatho eziyinhloko zivame ukusetshenziswa kakhulu ekwenzeni noma ezitolo zemishini emincane futhi uma kungenjalo, azivamile ukusetshenziswa. Ezimweni eziningi, isixhumanisi esiyinhloko esiyi-oblong singasetshenziswa esikhundleni salokho.
Izixhumanisi zokuhlanganisa zingase zibe yimishini noma ezishiselwe futhi ngokuyinhloko zisetshenziselwe ukuxhuma ingxenye yeketango kusixhumanisi esiyinhloko noma esilinganisweni. Angase futhi asetshenziselwe ukudala ukuxhumana phakathi kwezixhumanisi eziyinhloko, izingwegwe, noma ezinye izingcezu zehadiwe.
Izixhumanisi zokuhlanganisa ezishiselwe, njengazo zonke ezinye izixhumanisi kuketango, zixhunywe kusixhumanisi esiyinhloko noma isiphetho esifashisayo futhi sivalwe ngokushiselwe ukwakha uxhumano.
Isithombe esivezwe kulesi sigaba sibonisa izindlela ezimbili ezihlukene isixhumanisi sokuhlanganisa esishiselwe esingasetshenziswa. Esithombeni esingakwesokunxele, isixhumanisi sixhunywe unomphela kuhhuku yamehlo futhi sisetshenziselwa ukuxhuma idivayisi kuhhuku ejikayo. Ngakwesokudla, izixhumanisi zokuhlanganisa ezishiselwe zisetshenziselwa ukuvikela imilenze yeketanga nokubamba izingwegwe kusixhumanisi esiyinhloko.
I-Hammerlok® Ihlanganisiwe futhi Yahlakazwa
Amagama amathathu ebhrendi ajwayelekile ezixhumanisi zokuhlanganisa ahlanganisa:
• I-Hammerlok® (umkhiqizo we-CM)
• Kuplex® Kuplok® (Peerless brand)
• I-Lok-a-Loy® (umkhiqizo we-Crosby)
I-Kuplex® Kupler®, nayo engumkhiqizo ongena-Peerless, ingolunye uhlobo oluvamile lwesixhumanisi sokuhlanganisa. Lezi zixhumanisi zokuhlanganisa zinokubukeka okuhluke kancane okufana neketango. Kukhona uhhafu womzimba owodwa kuphela lapho uxhumano lwenziwa khona ngephinikhodi yokulayisha kanye nephinikhodi yokugcina. Uma kubhekwa ukuthi awekho ama-halves amabili omzimba, i-Kuplex® Kupler® ayincikile phakathi nendawo.

3. Izixhumanisi nezindandatho Izimpawu / Ukuhlonza
Ngokuya nge-ASME B30.26 Rigging Hardware, isixhumanisi ngasinye, i-master link subassembly, nendandatho izomakwa isikhathi eside ngumkhiqizi ukuze ibonise:
• Igama noma uphawu lokuhweba lomkhiqizi
• Usayizi noma umthwalo olinganiselwe
• Ibanga, uma kudingeka ukuhlonza umthwalo okaliwe
4. Izixhumanisi Nokususwa Kwezindandatho Kumibandela Yesevisi
Ngesikhathi sokuhlola, susa noma yiziphi izixhumanisi, isixhumanisi esiyinhloko sama-sub-assemblies, namaringi kusukela kusevisi uma noma yimiphi imibandela esohlwini lwe-ASME B30.26 Rigging Hardware ikhona.
• Umazisi olahlekile noma ongafundeki
• Izinkomba zokulimala kokushisa, okuhlanganisa i-weld spatter noma iziteleka ze-arc
• Umgodi noma ukugqwala ngokweqile
• Izingxenye ezithwala umthwalo ezigobile, ezisontekile, ezihlanekezelwe, ezeluliwe, ezinwetshiwe, eziqhekekile noma eziphukile
• Ama-nick amaningi noma ama-gouges
• Ukwehliswa ngo-10% kobukhulu boqobo noma bekhathalogi nganoma yisiphi isikhathi
• Ubufakazi bokushisela noma ukuguqulwa okungagunyaziwe
• Ezinye izimo, kuhlanganise nomonakalo obonakalayo obangela ukungabaza ngokuqhubeka nokusetshenziswa
Uma kukhona noma yimiphi imibandela engenhla, idivayisi kufanele isuswe kusevisi futhi izobuyiselwa kusevisi kuphela uma/uma igunyazwe ngumuntu oqeqeshiwe.
5. Ukusonga
Sithemba ukuthi lesi sihloko sisizile ukukunikeza ukuqonda okuyisisekelo kokuthi izixhumanisi namaringi ayini, ukuthi asetshenziselwa ini, kanye nemibandela ehlobene yokuhlonza kanye nokuhlola ku-ASME B30.26 Rigging Hardware.
Ukukufingqa, izixhumanisi nezindandatho zisebenza njengezindawo zokuxhuma emhlanganweni wokugoqa noma umhlangano we-multiple-leg sling. Yize kunezinhlobo eziningi ezahlukene zezixhumanisi namasongo asetshenziswa ekurimbeni, izixhumanisi eziyi-oblong master yizona eziguquguquka kakhulu futhi ezivame ukusetshenziswa njengeizindandatho zomqoqi.
Izixhumanisi zokuhlanganisa zisetshenziselwa ukuxhuma izingxenye zeketango endaweni ehambisanayo noma indandatho yokuqoqa futhi ingase ibe ngomshini noma eshiselwe.
Njenganoma iyiphi enye ingxenye yezingxenyekazi zekhompuyutha, qiniseka ukuthi uthobela izindinganiso ezifanele ze-ASME nokususwa kumibandela yesevisi.
