Unyolo wamayendedwe(omwe amatchedwanso maunyolo omangira, maunyolo omangirira, kapena maunyolo omangira) ndi maunyolo achitsulo olimba kwambiri omwe amagwiritsidwa ntchito poteteza katundu wolemera, wosakhazikika, kapena wamtengo wapatali pamayendedwe apamsewu. Zophatikizidwa ndi ma hardware monga zomangira, mbedza, ndi maunyolo, amapanga dongosolo loletsa katundu lomwe limalepheretsa kusuntha kwa katundu, kuwonongeka, ndi ngozi.
Zofunika Kwambiri ndi:
- Kuteteza zida zomanga / zolemera (zofukula, ma bulldozer)
- Kukhazikika kwazitsulo zachitsulo, mizati yomangidwa, ndi mapaipi a konkire
- Makina onyamula, ma module a mafakitale, kapena katundu wokulirapo
- Malo omwe ali pachiwopsezo chachikulu (m'mbali zakuthwa, zolemera kwambiri, kutentha / kukangana)
Kufunika koyika ma chain chain:
- Chitetezo:Zimalepheretsa kusintha kwa katundu komwe kungayambitse ma rollovers kapena jackknifes.
- Kutsata:Imakwaniritsa zofunikira zamalamulo (mwachitsanzo, FMCSA ku USA, EN 12195-3 ku EU).
- Chitetezo cha katundu:Amachepetsa kuwonongeka kwa katundu/magalimoto.
- Mtengo Mwachangu:Zogwiritsidwanso ntchito komanso zokhalitsa ngati zisamalidwa bwino.
Nayi chiwongolero chokwanira choyendetsera / kutsekereza maunyolo oteteza katundu wamagalimoto, kuwongolera mfundo zina zomwe zimaganiziridwa bwino ndi mafakitale:
| Mbali | Unyolo Wamayendedwe | Masamba a Webbing |
|---|---|---|
| Zakuthupi | Aloyi zitsulo (Makalasi G70, G80, G100) | Polyester / nayiloni ukonde |
| Zabwino Kwambiri | Zolemetsa zakuthwa, zolemera kwambiri (> 10T), kukangana kwakukulu / kuyabwa, kutentha kwakukulu | Malo osakhwima, katundu wopepuka, |
| Mphamvu | WLL yapamwamba kwambiri (20,000+ lbs), yotambasula pang'ono | WLL (mpaka 15,000 lbs), kutsika pang'ono |
| Kukana Zowonongeka | Imakana mabala, abrasion, kuwonongeka kwa UV | Zowopsa ku mabala, mankhwala, kuwala kwa UV |
| Chilengedwe | Kunyowa, mafuta, kutentha, kapena zopweteka | Malo ouma, olamulidwa |
| Ntchito Wamba | Zopangira zitsulo, makina omanga, zitsulo zolemera kwambiri | Mipando, magalasi, malo opaka utoto |
Kusiyana Kwakukulu:Unyolo umaposa katundu wolemetsa, wopweteka, kapena wakuthwa kumene kulimba ndikofunikira; maukonde amateteza malo osalimba ndipo ndi opepuka/osavuta kugwila.
A. Kusankhidwa kwa Chain
1. Nkhani Zamagulu:
-G70 (Transport Chain): Kugwiritsa ntchito zonse, ductility wabwino.
-G80 (Lifting Chain):Mphamvu zapamwamba, zofala pachitetezo.
-G100:Kuchuluka kwamphamvu kwa kulemera kwamphamvu (kugwiritsa ntchito ndi zida zofananira).
- Nthawi zonse gwirizanitsani giredi ya unyolo ndi giredi ya Hardware.
2. Kukula & WLL:
- Werengetsani zovuta zonse zofunika (pa malamulo monga EN 12195-3 kapena FMCSA).
- Chitsanzo: 20,000 lb katundu amafunikira ≥5,000 lbs tension pa unyolo (4: 1 chitetezo factor).
- Gwiritsani ntchito maunyolo okhala ndi WLL ≥ kukanika kowerengeka (mwachitsanzo, 5/16" G80 unyolo: WLL 4,700 lbs).
B. Kusankha kwa Hardware
- Zomangamanga:
Ma Ratchet Binders: Kuvuta kolondola, kugwirira ntchito kotetezeka (koyenera katundu wovuta).
Ma Lever Binders: Mofulumira, koma pachiwopsezo cha snap-back (amafunikira maphunziro).
- Zokowera / Zowonjezera:
Grab Hooks: Lumikizani ku maulalo a unyolo.
Slip Hooks: Nangula kumalo okhazikika (mwachitsanzo, chimango chagalimoto).
Maulalo a C-Hooks/Clevis: Zolumikizira zapadera (monga, maso achitsulo).
- Zida: Zoteteza m'mphepete, zowunikira zovuta, maunyolo.
C. Katundu-Mwachindunji Zosintha
- Makina Omanga (mwachitsanzo, Excavator):Unyolo wa G80 (3/8"+) wokhala ndi zomangira za ratchet;Sungani mayendedwe / mawilo + malo olumikizira; kuletsa kusuntha kwa mawu.
- Zitsulo zachitsulo:Unyolo wa G100 wokhala ndi makoko a C kapena makoko;Gwiritsani ntchito "chithunzi-8" kudutsa m'diso la coil.
- Miyezo ya Structural:Unyolo wa G70/G80 wokhala ndi dothi lamatabwa kuteteza kutsetsereka;Cross-chain pakona ≥45 ° kuti mukhale okhazikika.
- Mipope ya Konkire: Chock malekezero + maunyolo pamwamba pa chitoliro pa 30 ° -60 ° ngodya.
A. Kuyang'anira (Asanayambe/Akamaliza Kugwiritsa Ntchito Iliyonse)
- Maulalo a Chain:Kanani ngati: Kutambasula ≥3% ya kutalika, ming'alu, nick> 10% ya ulalo awiri, weld splatter, dzimbiri kwambiri.
- Ndolo / Unyolo:Kanani ngati: Zopotoka, kutseguka kwa mmero> kuwonjezeka kwa 15%, ming'alu, zingwe zotetezedwa.
- Zomangamanga:Kanani ngati: Chigwiriro/thupi lopindika, zomangira/magiya otha, mabawuti omasuka, dzimbiri mu makina a ratchet.
- General:Yang'anani zovala pamalo olumikizirana (mwachitsanzo, pomwe unyolo umakhudza katundu);Tsimikizirani zilembo za WLL zovomerezeka ndi masitampu agiredi.
B. Njira Zosinthira
- Kusintha Kovomerezeka:Ming'alu yowoneka, kutalika, kapena sitampu yosawerengeka;mbedza/unyolo wopindidwa>10° kuchokera ku mawonekedwe apachiyambi;Chain link kuvala > 15% ya mainchesi oyambirira.
- Kusamalira Kuteteza:Mafuta omangira ratchet pamwezi;Bwezerani zomangira zaka 3-5 zilizonse (ngakhale zitakhala zosasunthika; zobvala zamkati sizikuwoneka);Pumulani maunyolo pambuyo pa zaka 5-7 zogwiritsidwa ntchito kwambiri (zolemba zolemba).
C. Zolemba
- Sungani zipika zomwe zili ndi masiku, dzina la oyendera, zomwe mwapeza, ndi zomwe mwachita.
- Tsatirani miyezo: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
