Imiyoboro y'ubwikorezi(zitwa kandi iminyururu ihambiriye, iminyururu ihambiriye, cyangwa iminyururu ihambiriye) ni iminyururu ikomeye cyane y'icyuma ikoreshwa mu gufata imizigo iremereye, idahuye, cyangwa ifite agaciro kanini mu gihe cyo gutwara imizigo mu muhanda. Iyo ihujwe n'ibikoresho nk'ibifunga, imigozi, n'imishumi, ikora uburyo bukomeye bwo gukumira imizigo burinda ko imizigo ivamo, kwangirika, n'impanuka.
Porogaramu z'ibanze ni izi zikurikira:
- Gukingira ibikoresho by'ubwubatsi/ibiremereye (imashini zicukura, amabati)
- Gutuza imiyoboro y'ibyuma, imiyoboro y'ubwubatsi, n'imiyoboro ya sima
- Gutwara imashini, modules z'inganda, cyangwa imizigo minini cyane
- Ahantu hashobora gutera ibyago byinshi (impande zikonje, uburemere bukabije, ubushyuhe/gushyuha)
Akamaro ko gushyiraho imiyoboro y'ubwikorezi:
- Umutekano:Birinda guhindagurika kw'imizigo bishobora gutera guhindagurika cyangwa imisumari.
- Gukurikiza amategeko:Yujuje ibisabwa n'amategeko (urugero, FMCSA muri Amerika, EN 12195-3 muri EU).
- Kurinda Umutungo:Bigabanya kwangirika kw'imizigo/amakamyo.
- Uburyo bwo gukoresha neza ikiguzi:Irashobora kongera gukoreshwa kandi iramba iyo ifashwe neza.
Dore ubuyobozi bwuzuye bwo gutwara/gushyira iminyururu mu mikandara kugira ngo imizigo y'amakamyo ikomeze kwitabwaho, buvuga ku ngingo zimwe na zimwe zitabwaho n'inganda:
| Ikiranga | Imiyoboro y'ubwikorezi | Imigozi yo ku rubura |
|---|---|---|
| Ibikoresho | Ibyuma by'icyuma (Ibyiciro bya G70, G80, G100) | Urushundura rwa polyester/nylon |
| Ibyiza Kuri | Imitwaro ikarishye, uburemere bukabije (> 10T), gukururana/gushwanyagurika cyane, ubushyuhe bwinshi | Ubuso bworoshye, imizigo yoroheje, |
| Imbaraga | WLL iri hejuru cyane (ibiro 20.000+), ifite ubushobozi buke bwo kuyikoresha | WLL (kugeza kuri lbs 15.000), uburimbane buto |
| Ubudahangarwa ku byangiritse | Irwanya gukomereka, kwangirika, kwangirika kwa UV | Ishobora kwangirika kubera gucibwa, imiti, no gucika burundu kw'imirasire y'izuba |
| Ibidukikije | Ahantu hatose, hafite amavuta menshi, hashyushye cyangwa hateye ubwoba | Ahantu humutse kandi hagenzurwa |
| Imikoreshereze Isanzwe | Imashini z'ubwubatsi, ibyuma biremereye by'ubwubatsi | Ibikoresho byo mu nzu, ikirahure, ubuso bwasizwe irangi |
Itandukaniro ry'ingenzi:Iminyururu irakora neza mu mitwaro iremereye, igoye, cyangwa ikarishye aho gukomera ari ngombwa; ubudodo burinda ubuso bworoshye kandi bworoshye/bworoshye gufata.
A. Guhitamo uruhererekane
1. Ingano y'amanota:
-G70 (Uruhererekane rw'Ubwikorezi): Ikoreshwa muri rusange, ubushobozi bwo kugenda neza.
-G80 (Urunigi rwo Kuzamura):Ingufu nyinshi, zisanzwe mu kurinda umutekano.
-G100:Igipimo cyo hejuru cy'imbaraga ugereranyije n'uburemere (koresha hamwe n'ibikoresho bihuye).
- Buri gihe huza urwego rw'uruhererekane n'urwego rw'ibikoresho.
2. Ingano n'ubwishingizi bw'umutungo:
- Kubara igiteranyo cy'imbaraga zikenewe (bikurikije amabwiriza nka EN 12195-3 cyangwa FMCSA).
- Urugero: 20.000 lb umutwaro ukeneye ≥ 5.000 lbs kuri buri mugozi (4: 1 security factor).
- Koresha iminyururu ifite umuvuduko wa WLL ≥ wabazwe (urugero, umunyururu wa G80 wa 5/16": WLL 4,700 lbs).
B. Guhitamo ibikoresho
- Ibikoresho byo gufunga:
Ibikoresho byo gufunga Ratchet: Bifasha cyane, kandi bifasha mu gucunga neza (bikwiriye imitwaro ikomeye).
Ibikoresho byo gufunga ibyuma: Bihuta, ariko bishobora gutuma ibyuma bisubira inyuma (bisaba imyitozo).
- Imigozi/Ibikoresho byometseho:
Gufata Ibikoresho: Huza ku miyoboro y'urunigi.
Udukingirizo: Ifata ku ngingo zidahinduka (urugero, icyuma cy'ikamyo).
Amasano ya C-Hooks/Clevis: Ku bikoresho byihariye (urugero, amaso y'icyuma).
- Ibikoresho: Ibirinda impande, ibipima umuvuduko, iminyururu.
C. Imiterere yihariye y'umutwaro
- Imashini z'ubwubatsi (urugero, Imashini icukura):iminyururu ya G80 (3/8"+) ifite udukoresho two gufatanya uduce duto;Komeza inzira/amapine + aho bifatanye; wirinde ko umurongo ugenda.
- Ibikoresho by'icyuma:iminyururu ya G100 ifite udupira twa C cyangwa chocks;Koresha "ishusho-8" yo gushyiramo imigozi inyuze mu jisho rya coil.
- Imitako y'imiterere:iminyururu ya G70/G80 ifite uduce tw'ibiti kugira ngo idatemba;Umunyururu unyuranyije ku nguni ≥45° kugira ngo ukomeze ku ruhande.
- Imiyoboro ya beto: Impande zometseho + iminyururu hejuru y'umuyoboro ku nguni za 30°-60°.
A. Igenzura (Mbere/Nyuma ya Buri Ikoreshwa)
- Imiyoboro y'uruhererekane:Kwanga niba: Yarambuye ≥3% by'uburebure, imikato, imigozi >10% by'umurambararo w'urukiramende, isuka, ingese ikomeye.
- Imigozi/Amapingu:Kwanga niba: Igoramye, umuhogo ufunguka >15% wiyongereye, ucitsemo ibice, ubuze imigozi y'umutekano.
- Ibikoresho byo gufunga:Kwanga niba: Umukingo/umubiri ugonze, ibirenge/amapine byashaje, amaboliti adafunguye, ingese mu buryo bwo gukubita.
- Rusange:Reba niba nta byangiritse ahantu hahurira (urugero, aho umunyururu ukoze ku mutwaro);Genzura ibimenyetso bya WLL bisomeka neza n'amakashe y'icyiciro.
B. Amabwiriza yo gusimbuza
- Gusimbuza byemewe:Imyanya iyo ari yo yose igaragara, uburebure, cyangwa ikimenyetso cy’urwego rw’inyuguti ntibisomeke;Imigozi/imishumi igonze >10° uvuye ku ishusho y'umwimerere;Udupira tw'urunigi turi hejuru ya 15% by'umurambararo w'umwimerere.
- Kubungabunga impanuka:Siga amavuta yo gufunga irangi buri kwezi;Simbuza ibikoresho byo gufatanya buri myaka 3-5 (nubwo byaba ari nta kibazo; ubusaza bw'imbere ntibugaragara);Guhagarika akazi nyuma y'imyaka 5-7 yo gukoreshwa cyane (gusuzuma inyandiko).
C. Inyandiko
- Kubika inyandiko ziriho amatariki, izina ry'umugenzuzi, ibyavuye mu bushakashatsi, n'ibikorwa byakozwe.
- Kurikiza amahame ngenderwaho: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
