Mu rwego rw’ibijyanye n’ubwikorezi n’ubwikorezi, umutekano w’imizigo si intambwe y’ingenzi gusa, ahubwo ni imbogamizi ikomeye hagati yo kuyigeza mu buryo butekanye no kwangirika gukabije. Nubwo akenshi bisa n’ahoiminyururu yo guterura,iminyururu ihambira n'iminyururu ihambira(bizwi nka imiyoboro y'ubwikorezi) bifite intego yihariye kandi y'ingenzi. Byakozwe by'umwihariko kugira ngo bifashe imizigo iremereye mu gihe cyo gutwara abantu, ntabwo ari ibyo guterura hejuru y'imodoka.
Nkuko byavuzwe muri urwo rwego, izi nsinga zikorera hafi yaiminyururu yo guteruraKu bijyanye n'ingaruka zo gutsindwa—ibibazo birimo umutekano w'abantu n'ubusugire bw'imizigo ihenze cyane. Impanuka iterwa no gucika k'umunyururu ishobora gutera imvune ikomeye ku bantu, kwangirika kw'imodoka, no gutakaza imizigo yose. Kubwibyo, ubwiza bw'icyuma n'uburyo bwo kuvura ubushyuhe ni ingenzi cyane. Ariko, ibikoresho byonyine ntibihagije; uburyo bwo kubikoresha, buyobowe n'amahame y'ubuhanga n'uburambe mu kazi, bugira uruhare runini.
Kuri SCIC (www.scic-chain.com), dutangaiminyururu yo gufunga no gufungabyakozwe mu cyuma cy’ibyuma bikozwe mu cyuma gikozwe mu buryo bw’amajwi. Buri gice gikorerwa igenzura n’igeragezwa rikomeye kugira ngo tumenye neza ko tutatanga ibicuruzwa gusa, ahubwo ko ari garanti y’umutekano. Iyi nyandiko igaragaza ibipimo by’ingenzi, inzira zo gukora aho hantu, ingamba z’ingenzi zo kwirinda, n’ibipimo ngenderwaho bikenewe kugira ngo imiyoboro y’ubwikorezi ikoreshwe neza kandi mu buryo bwizewe.
1. Ibipimo by'ingenzi by'ubuhanga
Gusobanukirwa imiterere ya tekiniki y'umuyoboro ni intambwe ya mbere yo gushyira mu bikorwa mu mutekano. Abakoresha n'abaguzi bagomba kureba kure y'ingano nyayo y'umuyoboro hanyuma bagasesengura ingingo zikurikira z'ingenzi, zigomba gushyirwaho ikimenyetso gisobanutse neza ku muyoboro cyangwa ku kirango cyawo.
a) Umutwaro ntarengwa w'akazi (WLL) ugereranije n'imbaraga zo kugabanya
- Umutwaro ntarengwa wo gukora (WLL): Iyi ni imbaraga ntarengwa muri daN (dekaNewton) cyangwa ibiro umuyoboro mushya wemerewe gukomeza mu gukurura mu buryo bugororotse mu gihe cy'akazi gasanzwe. Iyi ni yo ntarengwa "ifite umutekano". Ku bijyanye no gushyiramo imigozi, iyi ikunze kwitwa Ubushobozi bwo gufunga (LC).
- Imbaraga zo Gucika (BF): Iyi ni yo mbaraga ntoya umuyoboro uzacikamo mu gihe cy'igerageza ryangiza. Iruta cyane WLL. Hakoreshwa uburyo busanzwe bwo kwirinda (ubusanzwe 4:1 ku miyoboro y'ubwikorezi), bivuze ko umuyoboro ukomeye inshuro enye kurusha WLL yawo.
b) Icyiciro n'ibikoresho
Iminyururu igezweho yo gutwara ibintu ikozwe mu byuma bivanze, itunganywa n'ubushyuhe kugira ngo igere ku miterere yihariye ya mekanike.
-Icyiciro cya 8 (urugero, Icyiciro cya 80 cyangwa 100): Iyi ni yo ngamba ikoreshwa mu nganda mu gusimbuza imishumi ifite imikorere yo hejuru. Umubare (80 cyangwa 100) werekeza ku rwego rw'icyiciro, ari na rwo rugena imbaraga zo gukurura.Urunigi rw'icyiciro cya 100itanga WLL iri hejuru ku gipimo kimwe ugereranije naIcyiciro cya 80, bigatuma iminyururu yoroheje kandi byoroshye kuyifata hatabayeho gutakaza imbaraga.
- Imiterere y'ibikoresho: Icyuma cya alloy kigomba kuba gifite ubuzima bwiza kandi gihuye kugira ngo gishobore kwihanganira imbaraga zihindagurika z'ubwikorezi hatabayeho kuvunika gato.
c) Ingano n'uko bingana
- Ingano y'izina (Diameter): Ubunini bw'insinga y'icyuma ikoreshwa mu gukora amasano. Ibi bifitanye isano itaziguye na WLL.
- Ingano z'imbere: Uburebure n'ubugari biri imbere mu gice cy'urukiramende bigomba kuba bihagije kugira ngo ibice bihuza (nk'ingunguru n'imigozi) byicare neza bidafatanye.
d) Ibice bigize sisitemu
Sisitemu yo gufunga iminyururu si ibintu bifitanye isano n'iminyururu gusa. Aho intege nke cyane muri sisitemu niho hagena ubushobozi rusange.
- Ibikoresho byo ku mpera: Ingofero (urugero, ingofero zo gufata, ingofero zo ku mashyiga) n'iminyururu bigomba kugira WLL nibura ingana n'iy'umunyururu.
- Ibikoresho bitera imbaraga (Ratchet cyangwa Lever): Ibi bikoreshwa mu gushyira imbaraga zikenewe mbere yo gutera imbaraga ku mugozi kugira ngo umutwaro ukomeze.
2. Umurimo wo gukorera aho hantu: Gukingira umutwaro
Imikorere myiza isaba uburyo buhamye. Imiyoboro y'ubwikorezi ikoreshwa n'imbaraga "zidahinduka" (kwihuta, gufunga feri, gukonja) n'imbaraga zihinduka (gutigita). Intego y'imikorere aho hantu ni ukurwanya izo mbaraga.
a) Igenzura rya mbere yo gukoresha
Mbere yo gukoresha buri gihe, ni ngombwa kugenzura amaso.
- Gusuzuma mu buryo bw'amashusho: Reba aho ingingo zigoramye cyangwa zangiritse, utudomo, imiyoboro, n'ingese cyangwa ibitonyanga bikomeye.
- Uburyo bwo guhuza: Menya neza ko imikoranire ihinduka neza. Gukomera bishobora kugaragaza ko imbere hangiritse cyangwa ko hari umwanda.
- Igenzura ry'ibikoresho: Genzura ko imigozi idahindagurika, imyenge yayo idakomeye, kandi ko imigozi yayo y'umutekano (niba ishyizwemo) ikora neza.
b) Ubuhanga bwo Gukoresha
- Gukoresha umunyururu: Iminyururu igomba kunyura mu murongo ugororotse hagati y'aho imodoka ifata n'umutwaro. Irinde impande zityaye; niba umunyururu ugomba kunyura hejuru y'imfuruka ityaye, koresha intebe zo mu mfuruka zirinda cyangwa ibyuma birinda impande kugira ngo wirinde gucika kw'iminyururu.
- Gukoresha imbaraga:
1. Shyira umunyururu ku ngingo z'imigozi y'ikinyabiziga n'ingingo z'imizigo (urugero, impeta z'imigozi).
2. Koresha igikoresho gitera imbaraga (ratchet cyangwa lever hoist) kugira ngo ufate umuvuduko woroshye hanyuma ushyireho umuvuduko ubanziriza uwo muvuduko.
3. Gushyira imbaraga mbere y'umuvuduko bigomba kuba bihagije kugira ngo umutwaro ugume utembera mu gihe cy'ihindagurika risanzwe ry'ubwikorezi ariko ntibigomba kurenga 50% by'imbaraga z'umunyururu mu gihe cy'ihindagurika. Gushyira imbaraga nyinshi mu muvuduko bitera imbaraga zidasanzwe kuri sisitemu kandi bishobora kwangiza umutwaro.
- Gufata impera zirekuye: Uburebure bw'umunyururu urenze bugomba gufatwa neza kugira ngo hirindwe "umunyururu w'umushumi" mu gihe cyo kuwutwara, ibyo bikaba byakwangiza imizigo cyangwa umunyururu ubwawo.
c) Ubusumbane n'Uburinganire
Ku mizigo iremereye cyangwa ifite agaciro gakomeye, uburyo bwo kuyihambira bugomba kuba buringaniye. Umubare w'imishumi n'inguni yayo (inguni yo kuyihambira) ni ingenzi cyane. Ubushobozi bwo kuyihambira bugabanuka uko inguni itambitse igabanuka. Byaba byiza iyo imishumi igomba kuba hafi y'imishumi igana ku yindi kugira ngo idatera imbere.
3. Amabwiriza y'ingenzi yo kwirinda: Ibyo utagomba gukora
Ubunararibonye bwerekana ko ingaruka nyinshi z'uruhererekane rw'ibikoresho zidaterwa n'inenge mu nganda ahubwo ziterwa no kubikoresha nabi. Gukurikiza ingamba zikurikira ntibishobora kuganirwaho.
a) Nta guterura ibintu hejuru y'imodoka
Iri ni ryo tandukaniro ry'ingenzi cyane. Iminyururu yo gufunga ntabwo yagenewe guterura hejuru. Guterura bikubiyemo imbaraga zidasanzwe kandi zishobora kurenza imipaka y'imiterere idahindagurika y'ibice by'iminyururu yo gutwara. Gukoresha umunyururu wo gufunga mu gushyiraho uburyo bwo kuzamura ni ukutubahiriza umutekano cyane.
b) Irinde kohereza ibintu bitunguranye
Gutembagara cyangwa guterana bitunguranye—nk'ikamyo itangiye mu buryo butunguranye cyangwa imizigo ihindukiye no “gufata” umugozi—bishobora guteza imbaraga zirenze kure WLL, bigatuma ivunika vuba ako kanya. Buri gihe imigozi igongana neza.
c) Kurinda ubushyuhe n'ingufu
- Ubushyuhe: Ibyuma bya aluminiyumu bitakaza imbaraga zabyo zikoreshwa mu bushyuhe iyo bihuye n'ubushyuhe bwinshi. Irinde ko byahura n'ibikoresho bishyushya cyangwa ibishashi byo gusudira.
- Gutera iminyururu: Ntugakurure iminyururu ku gishishwa cya sima cyangwa ahantu hatera iminyururu. Ibi bigabanya ibikoresho bihuza, bigagabanya agace gahuza iminyururu kandi bigatuma iminyururu igabanuka.
d) Irinde kuzunguruka no gupfundika
Nta na rimwe umunyururu ugomba gukoreshwa mu buryo bugoramye. Kuzunguruka bitera imbaraga zo guhindukira ku buryo umunyururu utari wagenewe gukoreshwa. Ntukigere ukoresha amapfundo kugira ngo ugabanure umunyururu; koresha agakoresho ko gufata gahagaze neza mu muyoboro.
e) Inguni yo Gutwara
Iyo umunyururu ukoreshejwe mu gupfunyika igikapu cyangwa mu buryo bw'amaguru menshi, imbaraga kuri buri kuguru ziyongera uko inguni iturutse ku ruhande ruhagaze yiyongera. Iyi "angle factor yo gupfunyika" igomba kubarwa kugira ngo hatagira ukuguru kumwe kurenza urugero.
4. Ibipimo ngenderwaho byo gusimbuza: Igihe cyo gusezera ku kazi k'umusimbura
Iminyururu ni ibintu byangiritse. Imara igihe ntarengwa. Gukomeza gukoresha iminyururu yashaje cyangwa yangiritse ni nk'ikintu cy'umutekano. Umunyururu ugomba guhita ukurwa mu mirimo ugasimburwa niba hari kimwe muri ibi bikurikira kibayeho:
a) Guhinduka kw'imiterere
- Uburebure: Pima umugozi ku burebure runaka (urugero, imigozi 10). Iyo uburebure bwapimwe burenze urugero rw'umukozi (ubusanzwe uburebure bwa 3-5%), umugozi uba waragutse kandi watakaje ubuziranenge bwawo bukoreshwa mu bushyuhe. Iki ni ikimenyetso cy'ibanze cy'uko hakiri kare hadakora neza.
- Imiyoboro Igonze cyangwa Igonze: Imiyoboro iyo ari yo yose igaragara ko igonze iva mu murongo wayo wa mbere igaragaza ko hari ikintu kirenze urugero.
b) Kwangirika no gutakaza ibice
- Kwambara ku ngingo zo gutwara: Pima umurambararo w'umurambararo aho insinga zihurira. Niba umurambararo wagabanutseho ibirenze 10% (reba ibisobanuro by'uwakoze), umugozi ugomba gusimburwa. Icyuma gito ntigishobora kwihanganira umutwaro ugenwe.
- Gupfuka no Gutera: Udupira twinshi dutuma umuntu yishyira mu mwanya utaringaniye aho imitsi ishobora gutangirira.
c) Imiterere y'ubuso
- Uduce: Ndetse n'uduce tw'umusatsi mu buso bw'aho uhurira ni impamvu yo kwangwa ako kanya.
- Kwangirika gukabije: Gushonga kw'ingufu bishobora kongera stress. Iyo ubuso bupfutse cyane, umunyururu urahungabana.
d) Imiterere y'ibikoresho
- Ingofero: Simbuza ingofero niba umwobo w'umuhogo ugoramye cyangwa wafungutseho ibirenze 15%, cyangwa niba hari ikintu kigaragara cyangiritse ku ntebe y'ingofero.
e) Amakuru abura cyangwa adashobora gusomwa
Niba ikimenyetso cy'amanota cyangwa ikimenyetso cya WLL cy'uruganda kibuze, kandi urunigi rudashobora kumenyekana neza, rugomba gukurwa kuri serivisi. Ntushobora gukoresha icyo udashobora kumenya mu mutekano.
Iminyururu ihambira no kuyihambirahoni abarinzi b'umutekano w'imizigo bacecetse. Muri SCIC, twemeza ko ibikoresho fatizo—icyuma cyacu cy'ibyuma by'urusaku—n'uburyo bwo kubikora byujuje ibisabwa byo mu rwego rwo hejuru mu buziranenge bw'ibyuma. Binyuze mu igenzura n'isuzuma rikomeye, dutanga imiyoboro ushobora kwizera.
Ariko, turasaba abakora n'abaguzi bose kwibuka ko urunigi rwizewe gusa nk'uko bigenda ku ikoreshwa ryarwo. Mu kubahiriza umutwaro ntarengwa w'akazi, kubahiriza amategeko meza yo gukora, no kubahiriza amabwiriza akomeye yo gusimbuza, uba urema umuco w'umutekano urinda ubuzima bw'abantu, urinda imizigo ihenze, kandi ugakora ibishoboka byose kugira ngo urugendo rwose rusozwe neza.
Kubijyanye n'ibisobanuro bya tekiniki cyangwa kugisha inama ku bijyanye n'uruhererekane rukwiye rw'ibyifuzo byawe, hamagaraSCICuyu munsi.
