Ulwazi Oluvamile Mayelana Nebhande Le-Ratchet Tie Down

I-SHF:

Amandla esandla ajwayelekile: Amandla okusebenza kwesandla angu-500N(50daN kulebula).

I-STF:

Amandla okucindezela ajwayelekile: Amandla asele ngemva kokukhulula isibambo sebhakede le-ratchet.

Ukwelulwa:

Ukulinganiswa kokwelula, emthwalweni othile, kuvezwa njengephesenti lobude bokuqala obungalayishwanga. Zonke izinto ezingaphansi kokucindezeleka zizokwelula futhi izinto ezahlukene zinezinga elihlukile lokunwebeka emthwalweni ofanayo wokunwebeka.

Kwibhande le-ratchet, ubude busukela ku-4% kuya ku-7%.

Izinga lokushisa:

Ibhande lokubopha phansi usebenzisa i-polypropylene noma i-polyester webbing akufanele lisetshenziswe emazingeni okushisa angaphezu kuka-90℃ noma ngaphansi kuka--40℃.

Ukulungisa:

Akumelwe kube nokulungiswa kwamaphethini e-webbing, ama-ratchet buckle, ama-hook noma amaphethini okuthunga/okuthunga.

Okujwayelekile:

I-EN 12195-2, i-AS/NZS 4380, kanye ne-WSTDA-T-1 zonke ziyizindinganiso ezilawula imininingwane, ukuhlolwa, kanye nokusetshenziswa kwezintambo ze-ratchet kanye nezinhlangano zokubopha ezisetshenziselwa ukubopha imithwalo. Nakuba zifana ngenhloso, zinomehluko ngokusekelwe endaweni yazo, izidingo ezithile, kanye nezindlela zokuhlola.

1. I-EN 12195-2

• Isifunda: IYurophu (Izinga laseYurophu).
• Isihloko: Imihlangano Yokuvimbela Umthwalo Ezimotweni Zomgwaqo – Ukuphepha Ingxenye 2: Ukubopha Izintambo Zewebhu Okwenziwe Ngezintambo Zokwenziwa Ngumuntu.
• Ububanzi:Ukusetshenziswa: Igxile ezidingweni zokuthutha izimoto zaseYurophu, okuhlanganisa amadivayisi okucindezela, amandla okubopha (LC), kanye nokuhambisana nemithetho yokuphepha emgwaqweni yaseYurophu.
  • Imboza izinhlelo zokulenga ezenziwe ngemicu yokwenziwa.
  • Icacisa izidingo ezincane zobukhulu, izinto zokwakha, ukusebenza, kanye nokuhlolwa.
  • Kufaka phakathi izibalo ezinemininingwane zamandla okubamba.
  • Ugcizelela izici zokuphepha, imikhawulo yobude, kanye namandla okuphuka.
• Amandla okuphuka: Umthamo womthwalo: = 2:1

2. I-AS/NZS 4380

• Isifunda: I-Australia neNew Zealand.
• Isihloko: Izinhlelo Zokuvinjelwa Kwemithwalo – Ama-Webbing Load Restraint Assemblies.
• Ububanzi:Ukusetshenziswa: Yakhelwe izimboni zokuthutha zasekhaya nezokuthumela kwamanye amazwe e-Australia naseNew Zealand, ukuqinisekisa imikhuba yokuvimbela umthwalo ephephile.
  • Ichaza imininingwane yezintambo zokubopha ezisetshenziselwa ukubopha imithwalo.
  • Kufaka phakathi izakhiwo zezinto, ubukhulu, izidingo zokusebenza, kanye nezindinganiso zokulebula.
  • Igxila ekuqineni ezimweni zemvelo ezinzima, njengokumelana ne-UV kanye namazinga okushisa aphezulu, okubaluleke kakhulu e-Australia naseNew Zealand.
  • Kudinga isici esithile sokuphepha sokuphula imithwalo, isembozo esivikelayo ku-webbing.
• Amandla okuphuka: Umthamo womthwalo::= 2:1

3. I-WSTDA-T-1

• Isifunda: I-United States (eyanyatheliswa yi-Web Sling & Tie Down Association).
• Isihloko: Incazelo Ejwayelekile Enconywayo Yokuncishiswa Kwe-Web Yokwenziwa.
• Ububanzi:Ukusetshenziswa: Isetshenziswa kakhulu eNyakatho Melika, igxile ezimbonini zezokuthutha kanye nemithethonqubo yezokuthutha kahulumeni.
  • Inikeza iziqondiso zokuklama, ukuhlola, kanye nokusetshenziswa kwezintambo zokubopha iwebhu ezenziwe ngokwenziwa.
  • Igxila emandleni ezinto ezibonakalayo, imikhawulo yobude, kanye nokumelana nezici zemvelo (isb., ukuwohloka kwe-UV kanye nokuchayeka kumakhemikhali).
  • Kudinga ukulebula okufanele ngemikhawulo yomthwalo wokusebenza (i-WLL) kanye nemininingwane yokuhlonza.
  • Isici sokuphepha ngokuvamile singu-3:1 emkhawulweni womthwalo osebenzayo.
• Amandla okuphuka: Umthamo womthwalo = 3:1
