1. Umkhawulo Womthwalo Wokusebenza Wezintambo Zensimbi Eziyindilinga
Kungakhathaliseki ukuthi uthutha imishini, usebenzisa amaketanga okudonsa, noma usembonini yokugawula imithi, kubalulekile ukwazi imikhawulo yomthwalo osebenzayo weketanga olisebenzisayo. Amaketanga anomkhawulo womthwalo osebenzayo - noma i-WLL - cishe okukodwa kwamandla awo okuphuka (inani lamandla amaketanga angamelana nawo ngaphambi kokuba aphuke).
Izinga lochungechunge kanye nobubanzi kunquma umkhawulo womthwalo osebenzayo wochungechunge. Uchungechunge lufakwe kokubili izinga kanye nosayizi ukuze ukwazi ukunquma i-WLL yalo usebenzisa leli shadi.
2. Izinhlobo zeketanga
Ibanga 30 liwuchungechunge olunezinjongo eziningi nolunokonga. Olwaziwa nangokuthi i-Grade 30 Proof Coil Chain, abantu basebenzisa lo mkhiqizo ezimbonini nasemisebenzini eyahlukahlukene, okuhlanganisa ukwakhiwa okulula, izintambo zokuvimbela, kanye nasembonini yasolwandle. Akuphephile ukuphakamisa ngaphezulu. Intambo yebanga 30 ifakwa nge-embossed kusetshenziswa i-3, 30, noma i-300.
Lokhu kubizwa nangokuthi i-Grade 43 High Test Chain noma i-Grade 43 Tow Chain, kuvamile embonini yokudonsa nokufaka imithi. Ungalokothi usebenzise le chain ukuphakamisa ngaphezulu. Le chain ihlanganisa imiklamo eqoshiwe kusetshenziswa i-43 noma i-G4.
Iketanga Lokuthutha Lebanga 70, elibizwa nangokuthi "Iketanga Lamaloli Lebanga 70," lisebenza ekuqiniseni imithwalo yokuthutha ngaphezulu komgwaqo. Ungalokothi usebenzise leli ketanga kunoma yikuphi ukuphakamisa okungaphezulu. Leli ketanga lihlanganisa imiklamo eqoshiwe kusetshenziswa i-7, 70, noma i-700.
I-Grade 80 Alloy Chain isebenza ekuphakamiseni okungaphezulu ngenxa yomklamo wayo ophathwa ngokushisa. Abantu bavame ukusebenzisa lolu hlobo lweketanga njengochungechunge oludonsayo olusindayo. I-Grade 80 chain ifaka imiklamo eqoshiwe kusetshenziswa i-8, 80, noma i-800.
Njengoba ibhekwa njengeketanga lekhwalithi ephezulu, inikeza umkhawulo womthwalo womsebenzi ophakeme cishe ngo-25% kunoketanga lwebanga lama-80. Iphephile ukuphakamisa ngaphezulu. Amaketanga ebanga lama-100 afaka imiklamo eqoshwe nge-10 noma i-100.
Njengomkhiqizo omusha emakethe, uchungechunge lwe-Grade 120 luqine ngamaphesenti angama-50 kune-Grade 80 kanye nochungechunge lwe-Grade 100 oluqine ngamaphesenti angama-20. Luphinde lumelane nokuguguleka kakhulu kune-Grade 80 kanye ne-Grade 100. Luphephile ekuphakamiseni okungaphezulu.
3. Funda kabanzi ngomehluko phakathi kwamabanga 70, 80 kanye ne-100 lapha:
Umbuzo ovamile ithimba lethu lokuthengisa eliwuzwa kumakhasimende mayelana nemikhiqizo yethu yochungechunge uthi “Yimuphi umehluko phakathi kochungechunge lwebanga lama-70, lama-80, lama-100, kanye nelama-120?” Sichaza umehluko phakathi kwalezi zigaba nokuthi yimaphi amaketanga okufanele uwasebenzise ngokwezidingo zakho.
Uchungechunge lweBanga lama-70
Uchungechunge lwebanga lama-70 lwenziwa ngensimbi yekhabhoni ephathwa ngokushisa. Okwaziwa nangokuthi "uchungechunge lwabathuthi bamaloli," abantu basebenzisa ibanga lama-70 njengezinto zokubopha ezinqoleni ezihamba emgwaqweni.Ungalokothi usebenzise le ketanga ukuphakamisa ngaphezulu.
Lolu hlobo ngokuvamile lune-gold chromate finish ngakho kulula ukuyibona. Luphinde luhlangabezane nezimfuneko ze-California Highway Patrol kanye ne-DOT. Ukusetshenziswa kwalolu chungechunge, ngaphandle kwezokuthutha, kufaka phakathi ukudonsa, ukugawula imithi, imishini yokumba uwoyela, kanye nezinhlelo zokuphepha.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-7, 70, noma 700.
Iketanga lika-80 liyiketanga lensimbi eliphathwa ngokushisa elinesilinganiso samandla aphezulu nesisindo. Amandla alo alenza liphephe ekuphakamiseni nasekuphakamiseni izihlilingi ngaphezulu. Lihle kakhulu futhi ekusetshenzisweni okufana nokubuyisa, ukuphepha, kanye nokuhudula amaketanga.
Lolu chungechunge luya ngokuya luvame kakhulu embonini yamaloli athwala abantu ukuze kuvikelwe imithwalo yezimboni esindayo. Ngoba lolu hlobo lwamaketanga luvame ukuhlonyiswa ngohlobo oluthile lwe-clevis grab hook, futhi izinhlangano ezinjalo zamaketanga azivunyelwe ukuphakamisa ngaphezulu.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-8, 80, noma 800.
Uchungechunge lweBanga lama-80
Uchungechunge lweBanga le-100
Iketanga le-Grade 100 liwumkhiqizo omusha futhi liya ngokuya lithandwa njengokungena esikhundleni seketanga le-grade 80. Njengoba libhekwa njengekhwalithi ephezulu ngabakhiqizi, linikeza imikhawulo yomthwalo wokusebenza ephakeme cishe ngo-25% kune-grade 80 futhi lisebenza ezinhlotsheni zokuphakamisa ezingenhla.
Abantu abaningi basebenzisa ibanga le-100 kunebanga lama-80 ukubopha imithwalo eyisicaba. Leli chungechunge liqukethe amandla engeziwe kanye nosayizi omncane ongahambisani nomkhawulo womthwalo osebenzayo.
Kodwa-ke, ngoba la maketanga ngokuvamile ahlonyiswe ngohlobo oluthile lwe-clevis grab hook, futhi izinhlangano ezinjalo zamaketanga azivunyelwe ukuphakamisa ngaphezulu.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-10, 100, noma 1000.
Uchungechunge lwebanga le-120 luyisigaba esisha sochungechunge olusebenza kahle kakhulu, olunikeza amandla aphezulu embonini. Isitayela sesixhumanisi esiyisikwele sidala ukuxhumana okwengeziwe phakathi kwezindawo zokuthwala ezixhumanisweni, okunciphisa ingcindezi kuchungechunge.
Lokhu kusho ukuthi imikhawulo yomthwalo osebenzayo iphakeme ngo-50% kunebanga lama-80, kanye no-20% ngaphezu kwebanga lama-100. Ibanga le-chain 120 lisebenza ekuphakamiseni okungaphezulu. Kubalulekile ukuqaphela ukuthi njengoba kunjalo nge-Grade 80 tie down chain assemblys kanye ne-Grade 100 tie down chain assemblys, i-chain assemblys nayo ayiphephile ekuphakamiseni okungaphezulu ngenxa yohlobo lwama-hook asetshenzisiwe.
Lolu hlobo lweketanga lunombala oluhlaza okwesibhakabhaka okhanyayo ukuze lubonakale kalula.
Uchungechunge lweBanga le-120
Kungakhathaliseki ukuthi uhlobo luni lweketanga, bonke kumele balandele izindinganiso ezibekwe yiNational Association of Chain Manufacturers (NACM), ezihlanganisa:
- Ungalokothi uthuthe noma ulengise imithwalo ephakanyisiwe phezu kwabantu.
- Hlola amaketanga ngezikhathi ezithile ukuze ubone imifantu, ama-gouges, ukuguguleka, ukunwebeka, ama-nick, kanye nokufaneleka kwawo.
- Amazinga okushisa ngokweqile noma ukuchayeka ezindaweni ezisebenzisa amakhemikhali njenge-asidi noma uketshezi oluqothulayo noma umusi kunganciphisa ukusebenza kweketanga.
- Xhumana nomkhiqizi weketanga uma iketanga lizosebenza ngaphandle kwebanga lokushisa elinconywayo (-40 °F kuya ku-400 °F).
- Susa uchungechunge kusevisi uma ubukhulu kunoma iyiphi ingxenye kusixhumanisi bungaphansi kwenani eliphansi elibhalwe ohlwini.
- Uma kuhlanganiswa izinhlobo zeketanga noma zezingxenye, konke kufanele kulinganiswe emkhawulweni womthwalo osebenzayo wengxenye noma iketanga elilinganiselwe kancane.
- Dlulisa amehlo ekukhetheni kwethu uchungechunge lwezokuthutha lwebanga lama-70, kanye nezilingi zeketanga.
