Ukuqonda amazinga ezintambo kubalulekile ekukhetheni intambo efanele yezimboni, yokuphakamisa, noma yezokuphepha. Njengoba kunezinhlobo eziningi kangaka zezintambo emakethe, sazi kanjani ukuthi sisebenzisa ibanga elifanele lezintambo kumaphrojekthi ethu? Isinyathelo sokuqala ukujwayelana namabanga ezintambo, ukuqedwa kwezintambo kanye nokuthi zisho ukuthini.
Ayini Ama-Chain Grades?
Ama-chain grade ayindlela yokuhlukanisa ama-alloy steel chain ngokusekelwe emandleni awo okudonseka kanye nomkhawulo womthwalo wokusebenza (WLL). Uma izinga liphezulu, i-chain iqina futhi ilukhuni.
| Ibanga | Izinto | Amandla Okuqina (psi) | Ukusetshenziswa Okuvamile |
| Ibanga lama-30 | Ikhoyili Yobufakazi (ikhabhoni) | ~30,000 | Umsebenzi olula: ukubopha, izithiyo |
| Ibanga 43 | Ukuhlolwa Okuphezulu (ikhabhoni) | ~43,000 | Ukubopha umthwalo, ukudonsa, ukuloba |
| Ibanga lama-70 | Ezokuthutha (ingxubevange) | ~70,000 | Uchungechunge lwezokuthutha, ukubopha amaloli |
| Ibanga lama-80 | Insimbi ye-alloy | ~80,000 | Iketanga lokuphakamisa, iketanga lamahlathi, ukubopha |
| Ibanga le-100 | Insimbi ye-alloy ye-premium | ~100,000 | Ukuphakamisa okunzima, izinti, ama-lifti aphezulu |
| Ibanga 120 | Insimbi ye-alloy ethuthukisiwe | ~120,000 | Ukuphakamisa okunzima okukhethekile |
Amagama Ayisihluthulelo Okufanele Uwazi:
1. Umkhawulo Womthwalo Osebenzayo (WLL):Isisindo esiphezulu iketanga elingasiphakamisa ngokuphephile.
2. Amandla Okuqina:Iketanga lamandla aphezulu lingamelana ngaphambi kokuphuka.
3. Ukuhlolwa Kobufakazi:Ukuhlolwa komthwalo othile (ngokuvamile okungu-2x WLL) ukuqinisekisa ukuthi akukho zinkinga.
Ukuqeda Iketanga:
Nasi isifinyezo esifushane salokho abakushoyo:
1. Ezinombala ozimele:akukho ukuqeda noma ukumboza
2. I-okside emnyama:I-okside emnyama noma ukufiphaza kuyingubo yokuguqulwa kwezinto zensimbi, esetshenziselwa ukwengeza ukumelana nokugqwala okuncane, ukubukeka, nokunciphisa ukukhanya.
3. I-Electro galvanized:i-electroplating yokufaka i-zinc ebusweni, ifakwa esixazululweni sikasawoti we-zinc, bese ugesi ubeka ungqimba lwe-zinc olubushelelezi, olucwebezelayo, oluncane, olufanayo
4. I-dip eshisayo ekhanyisiwe:Kuhilela ukucwilisa insimbi ku-zinc encibilikisiwe cishe ku-450°C, I-zinc isabela nensimbi ukuze yakhe izendlalelo ezijiyile ze-zinc-iron alloy, Inikeza ukumelana okungcono kokugqwala kwesikhathi eside, ikakhulukazi ngaphandle.
5. Impuphu embozwe: Ukugqoka ngempuphu uhlobo lokugqoka olusetshenziswa njengempuphu egeleza ngokukhululeka, eyomile.Izembozo zempuphu zingakhiqiza izembozo ezijiyile kakhulu kunezembozo ezivamile zoketshezi ngaphandle kokugijima noma ukugoba.
Qaphela:AmaBanga angu-80 nangaphezulu kuphela avunyelwe ukuphakamisa izimpahla ezithwala imithwalo ngokwezindinganiso ze-OSHA kanye ne-ASME.
Ukukhetha Uchungechunge Olufanele：
1. Nquma umthwalo:Yazi isisindo kanye nesici sokuphepha.
2. Imvelo:Iyagqwala, izinga lokushisa eliphezulu, njll.
3. Ukusetshenziswa:Ukuphakamisa, ukudonsa, ukubopha phansi, njll.
4. Imithethonqubo:I-OSHA, i-DOT, noma okunye ukuthobela imithetho.
Isiphetho：
Manje njengoba usuqonda umehluko emazingeni ahlukahlukene eketanga, ungasebenza ngokuphephile futhi ukhethe iketanga elifanele isicelo sakho. Futhi uma ufuna iketanga elisezingeni eliphezulu, i-G80 noma i-G100 lifting hook, i-chain sling, noma unemibuzo mayelana nokuthi yini oyidingayo, xhumana nathi lapha kwa-Qingdao Well Done Imp & Exp Co., Ltd.. Ochwepheshe bethu bazokujabulela kakhulu ukukusiza ukuthi uthole okudingayo.
