1. Umkhawulo Womthwalo Osebenzayo Wamaketanga Ensimbi Yesixhumanisi
Noma ngabe uthutha imishini, usebenzisa amaketanga okudonsa, noma usembonini yokugawula, kubalulekile ukwazi imikhawulo yomthwalo wokusebenza wamaketango owasebenzisayo. Amaketango anomkhawulo womthwalo osebenzayo- noma i-WLL- cishe ingxenye eyodwa kwezine yamandla awo ekhefu (inani lamandla amaketanga angamelana nawo ngaphambi kokuba anqamuke).
Ibanga leketango nobubanzi bunquma umkhawulo womthwalo wokusebenza weketango. I-Chain igcizelelwe kukho kokubili ibanga nosayizi ukuze ukwazi ukunquma i-WLL yayo usebenzisa leli shadi.
2. Izinhlobo zamaketango
IBanga lama-30 liyiketango elinezinjongo eziningi, elongayo. Eyaziwa nangokuthi i-Grade 30 Proof Coil Chain, abantu basebenzisa lo mkhiqizo ezimbonini ezihlukahlukene nemisebenzi, okuhlanganisa ukwakhiwa okulula, amaketanga okuvimbela, kanye nasembonini yasolwandle. Akuphephile ukuphakanyiswa phezulu. Iketanga leBanga lama-30 ligcizelelwe kusetshenziswa u-3, 30, noma 300.
Okuphinde kubizwe nge-Grade 43 High Test Chain noma i-Grade 43 Tow Chain, lokhu kuvamile ezimbonini zokudonsa nokugawula imithi. Ungalokothi usebenzise leli ketango ukuze uphakamise phezulu. Lolu chungechunge luhlanganisa imiklamo eqoshwe kusetshenziswa i-43 noma i-G4.
I-Grade 70 Transport Chain, ebizwa nangokuthi "i-Grade 70 Truckers Chain," isebenza ekutholeni imithwalo yokuthuthwa emgwaqweni. Ungalokothi usebenzise lolu chungechunge kunoma yikuphi ukuphakamisa phezulu. Lolu chungechunge luhlanganisa imiklamo eqoshwe kusetshenziswa i-7, 70, noma 700.
I-Grade 80 Alloy Chain isebenzela ukuphakamisa phezulu ngenxa yomklamo wayo ophethwe ukushisa. Abantu bavamise ukusebenzisa lolu hlobo lweketango njengeketango lokudonsa kanzima. Iketanga leBanga lama-80 lihlanganisa imiklamo eqoshwe kusetshenziswa i-8, 80, noma 800.
Njengoba kubhekwa uchungechunge lwekhwalithi yeprimiyamu, inikeza cishe umkhawulo womthwalo ophakeme ongu-25% ngaphezu kochungechunge lweBanga lama-80. Kuphephile ukuphakanyiswa phezulu. Amaketanga eBanga le-100 afaka imiklamo eqoshwe nge-10 noma i-100.
Umkhiqizo omusha emakethe, iketango leBanga le-120 linamandla afinyelela kwangama-50% kunochungechunge lweBanga lama-80 futhi luqine ngo-20% kuneketango leBanga le-100. Iphinde imelane nokuhuzuka kunawo womabili amaketango eBanga lama-80 nele-100. Kuphephile kumakheshi aphezulu.
3. Funda kabanzi mayelana nomehluko phakathi kwamabanga 70, 80 kanye nele-100 lapha:
Umbuzo ojwayelekile ithimba lethu labadayisi eliwuzwayo kumakhasimende mayelana nemikhiqizo yethu ewuchungechunge uthi “Uyini umehluko phakathi kwe-grade 70, 80, 100, kanye neketango le-120?” Sichaza umehluko phakathi kwalezi zigaba nokuthi yimaphi amaketanga okufanele uwasebenzise ngokwezidingo zakho.
I-Grade 70 Chain
Iketanga le-Grade 70 lenziwa ngensimbi ye-carbon efakwe ukushisa. Okwaziwa nangokuthi "uchungechunge lwabashayeli bamaloli," abantu basebenzisa ibanga lama-70 njengama-tie-down kuma-trailer asendleleni.Ungalokothi usebenzise leli ketango ukuze uphakamise phezulu.
Lolu hlobo ngokuvamile lufaka isiphetho se-chromate esagolide ngakho-ke kulula ukukubona. Iphinde ihlangabezane nezidingo ze-California Highway Patrol kanye ne-DOT. Ukusetshenziswa kwalolu chungechunge, ngaphandle kwezokuthutha, kufaka phakathi ukudonsa, ukugawulwa kwemithi, izinsimbi zikawoyela, nezicelo zokuphepha.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-7, 70, noma 700.
I-80 chain iyiketango lensimbi elashwe ngokushisa elinamandla amakhulu ukuya esisindweni. Amandla ayo ayenza ivikeleke ekuphakamiseni phezulu nasekuphakamiseni izihlilingi. Ilungele futhi ukusetshenziswa njengokululama, ukuphepha, namaketango okudonsa.
Lolu chungechunge seluvame kakhulu embonini yamaloli e-flatbed ukuze kuvikeleke imithwalo esindayo yezimboni. Ngoba lezi zinhlobo zamaketango ngokuvamile zifakwe uhlobo oluthile lwe-clevis grab hook, futhi amaketango anjalo awavunyelwe ukuphakanyiswa phezulu.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-8, 80, noma 800.
I-Grade 80 Chain
I-Grade 100 Chain
Iketanga le-Grade 100 liwumkhiqizo omusha futhi liya ngokuya liduma njengokungena esikhundleni seketango lebanga lama-80. Ibhekwa ikhwalithi yeprimiyamu abakhiqizi, inikeza imikhawulo yomthwalo osebenzayo ecishe ibe ngu-25% ephakeme kunebanga lama-80 futhi isebenzela izinhlelo zokusebenza zokuphakamisa phezulu.
Abantu abaningi basebenzisa ibanga le-100 ngaphezu kwebanga lama-80 ukuze bavikele imithwalo eyisicaba. Lolu chungechunge luqukethe amandla engeziwe kanye nosayizi omncane ongaphambani nomkhawulo womthwalo osebenzayo.
Kodwa-ke, ngenxa yokuthi la maketango ngokuvamile afakwe uhlobo oluthile lwe-clevis grab hook, futhi imihlangano enjalo ayivunyelwe ukuphakanyiswa phezulu.
Lolu chungechunge luhlanganisa imiklamo eqoshwe ngo-10, 100, noma 1000.
Iketanga leBanga le-120 liphinde libe yisigaba esisha sochungechunge lokusebenza okuphezulu, olunikeza amandla aphezulu embonini. Isitayela sokuxhumanisa isikwele sidala ukuthintana okwengeziwe phakathi kwezindawo ezithwalayo kuzixhumanisi, okunciphisa ingcindezi kuketango.
Lokhu kuhumusha imikhawulo yemithwalo yokusebenza ephakeme ngo-50% kunebanga lama-80, kanye no-20% ngaphezu kwebanga le-100. I-chain grade 120 isebenzela ukuphakamisa phezulu. Kubalulekile ukuqaphela ukuthi njengasemihlanganweni ehlanganisa iketango leBanga lesi-80 kanye nemihlangano ye-tie down chain assemblies, amaketango ahlanganayo nawo awaphephile ekuphakamiseni phezulu ngenxa yohlobo lwamahhuku asetshenziswayo.
Lolu hlobo lweketango lunombala oluhlaza okwesibhakabhaka okhanyayo ukuze lubonakale kalula.
I-Grade 120 Chain
Kungakhathalekile ukuthi hlobo luni lweketango, bonke kufanele balandele izindinganiso ezibekwe yi-National Association of Chain Manufacturers (NACM), okuhlanganisa:
- Ungalokothi uthuthe noma umise imithwalo ephakanyisiwe phezu kwabantu.
- Ukuhlola amaketanga ngezikhathi ezithile ukubona imifantu, ama-gouges, ukuguga, ama-elongation, ama-nick, nokufaneleka.
- Amazinga okushisa eqile noma ukuchayeka ezindaweni ezisebenza ngamakhemikhali njengama-acids noma uketshezi olubolayo noma intuthu kunganciphisa ukusebenza kweketango.
- Xhumana nomkhiqizi weketango uma amaketanga ezosebenza ngaphandle kwezinga lokushisa elinconywayo ( -40 °F kuya ku-400 °F).
- Khipha iketango enkonzweni uma ubukhulu kunoma iyiphi ingxenye kusixhumanisi bungaphansi kwenani eliphansi elifakwe ohlwini.
- Lapho kuxutshwa iketango noma izinhlobo zengxenye, konke kufanele kukalwe emkhawulweni womthwalo osebenzayo wengxenye enesilinganiso esiphansi kakhulu noma iketango.
- Phequlula esikukhethele iketango lezokuthutha lebanga lama-70, kanye nezihlilingi.
