1. Umutwaro ntarengwa w'imikorere y'iminyururu y'icyuma ihuza uruziga
Waba utwara imashini, ukoresha iminyururu ikurura, cyangwa uri mu nganda zikora ibiti, ni ngombwa kumenya imipaka y'umutwaro ukoresha. Iminyururu ifite umupaka w'umutwaro ukoreraho - cyangwa WLL - wa hafi kimwe cya kabiri cy'imbaraga zayo zo gucika (ingano y'imbaraga iminyururu ishobora kwihanganira mbere yuko icika).
Intera n'umurambararo w'umunyururu bigena umutwaro ntarengwa w'umunyururu. Umunyururu ushushanyijeho urwego n'ingano yawo kugira ngo ubashe kumenya WLL yawo ukoresheje iyi mbonerahamwe.
2. Ubwoko bw'urunigi
Icyiciro cya 30 ni urunigi rufite intego nyinshi kandi ruhendutse. Ruzwi kandi nka Icyiciro cya 30 Proof Coil Chain, abantu bakoresha iki gicuruzwa mu nganda zitandukanye n'imirimo, harimo ubwubatsi bworoheje, iminyururu y'inzitizi, no mu nganda zo mu mazi. Ntabwo ari byiza guterura hejuru y'amazi. Urunigi rwa 30 rushyirwamo ibishushanyo mbonera hakoreshejwe 3, 30, cyangwa 300.
Iyi miyoboro yitwa kandi Grade 43 High Test Chain cyangwa Grade 43 Tow Chain, ibi bikunze kugaragara mu nganda zikora imirimo yo gukurura no gusarura ibiti. Ntukigere ukoresha iyi miyoboro mu guterura hejuru. Iyi miyoboro irimo imiterere yashushanyije hakoreshejwe 43 cyangwa G4.
Urunigi rw'ubwikorezi rwo mu cyiciro cya 70, kandi rwitwa "Urunigi rw'Abashoferi b'Amakamyo rwo mu cyiciro cya 70," rukora mu gufata imizigo yo gutwara imodoka hejuru y'umuhanda. Ntukigere ukoresha urunigi mu guterura imodoka hejuru y'umuhanda. Urunigi rurimo imiterere yakozwe hakoreshejwe 7, 70, cyangwa 700.
Umunyururu wa Alloy wo mu cyiciro cya 80 ukoreshwa mu guterura hejuru bitewe n'imiterere yawo ikoreshwa mu bushyuhe. Abantu bakunze gukoresha ubu bwoko bw'umunyururu nk'umunyururu uremereye ukurura. Umunyururu wa 80 urimo imiterere ishushanyijeho hakoreshejwe 8, 80, cyangwa 800.
Ifatwa nk'umunyururu w'ubwiza buhanitse, itanga umutwaro ntarengwa wo gukora uri hejuru ya 25% ugereranyije n'umunyururu w'icyiciro cya 80. Ni nziza guterura hejuru. Iminyururu y'icyiciro cya 100 irimo imiterere yashushanyijeho 10 cyangwa 100.
Umugozi w’inyuma ku isoko, ni igicuruzwa gishya ku isoko, ufite imbaraga zigera kuri 50% kurusha umugozi w’inyuma ku kigero cya 80 na 20% kurusha umugozi w’inyuma ku kigero cya 100. Nanone kandi, urwanya kwangirika kurusha imigozi y’inyuma ku kigero cya 80 na 100. Ni mwiza ku guterura hejuru y’imodoka.
3. Menya byinshi ku itandukaniro riri hagati y'amashuri 70, 80 na 100 hano:
Ikibazo itsinda ryacu rishinzwe kugurisha rikunze kumva ku bakiriya ku bijyanye n'ibicuruzwa byacu ni iki: “Ni irihe tandukaniro riri hagati y'imigozi y'icyiciro cya 70, 80, 100, na 120?” Dusobanura itandukaniro riri hagati y'ibi byiciro n'imigozi ugomba gukoresha ukurikije ibyo ukeneye.
Urunigi rw'icyiciro cya 70
Umunyururu w’icyiciro cya 70 ukorwa mu byuma bishyushye bya karuboni. Uzwi kandi nka "umunyururu w’amakamyo", abantu bakoresha icyiciro cya 70 nk'imigozi ihambiriye ku magareta anyura hejuru y’umuhanda.Ntuzigere ukoresha uyu munyururu mu guterura hejuru y'imodoka.
Ubu bwoko muri rusange bufite irangi rya zahabu rya krometi bityo biroroshye kubimenya. Bunahuye n'ibisabwa na California Highway Patrol na DOT. Ikoreshwa muri uru ruhererekane, usibye gutwara abantu, harimo gukurura, gutema ibiti, ibikoresho byo guteka peteroli, n'ibikorwa by'umutekano.
Uyu muyoboro urimo igishushanyo mbonera gifite 7, 70, cyangwa 700.
Umunyururu wa 80 ni umunyururu w'icyuma ukoreshwa mu bushyuhe ufite igipimo cyo hejuru cy'uburemere. Uburemere bwawo butuma utekanye mu guterura no guterura iminyururu hejuru. Ni mwiza kandi mu gukoreshwa nko kugarura, kurinda no gukurura iminyururu.
Uyu muyoboro urimo kandi kugaragara cyane mu nganda zitwara amakamyo atwara imizigo iremereye mu nganda. Kubera ko ubu bwoko bw'imiyoboro muri rusange bufite ubwoko bwihariye bwa clevis grab hook, kandi bene ubwo bufatanye ntibwemerewe guterura hejuru y'imodoka.
Uyu muyoboro urimo igishushanyo mbonera gifite 8, 80, cyangwa 800.
Urunigi rw'icyiciro cya 80
Urunigi rw'icyiciro cya 100
Umugozi w’igorofa ya 100 ni igicuruzwa gishya kandi kirimo gukundwa cyane nk’igisimbura umugozi w’igorofa ya 80. Kubera ko ufatwa nk’uw’igiciro cyiza n’inganda, utanga imitwaro irenzeho 25% ugereranyije n’igorofa ya 80 kandi ukoreshwa mu guterura ibintu hejuru y’imodoka.
Abantu benshi bakoresha urwego rwa 100 ugereranyije n'urwego rwa 80 kugira ngo bafate imizigo irambuye. Uru runigi rufite imbaraga nyinshi n'ingano ntoya idaca ku mubare ntarengwa w'imizigo ikoreshwa.
Ariko, kubera ko iyi minyururu muri rusange ifite ubwoko bwihariye bwa clevis grab hook, kandi bene iyo minyururu ntiyemerewe guterurwa hejuru.
Uyu muyoboro urimo igishushanyo mbonera gifite 10, 100, cyangwa 1000.
Umunyururu w’icyiciro cya 120 na wo ni icyiciro gishya cy’umunyururu w’imikorere myiza, utanga imbaraga nyinshi mu nganda. Imiterere y’umunyururu w’impande zombi ituma habaho guhuza kw’ibice by’umunyururu ku minyururu, bigabanya umuvuduko ku munyururu.
Ibi bivuze ko imitwaro y'akazi iri hejuru ya 50% ugereranyije n'icyiciro cya 80, na 20% ugereranyije n'icyiciro cya 100. Ingano y'umunyururu 120 ikora mu guterura hejuru. Ni ngombwa kumenya ko kimwe n'ingano y'umunyururu 80 n'ingano y'umunyururu 100, ingano y'umunyururu nayo ntabwo itekanye mu guterura hejuru bitewe n'ubwoko bw'ingufu zikoreshwa.
Ubwo bwoko bw'urunigi bufite irangi ry'ubururu rirabagirana kugira ngo byoroshye kubumenya.
Urunigi rw'icyiciro cya 120
Uko ubwoko bw'urunigi bwaba buri kose, abantu bose bagomba kubahiriza amahame yashyizweho n'Ishyirahamwe ry'Igihugu ry'Abakora Urunigi (NACM), arimo:
- Ntukigere utwara cyangwa ngo ushyire imizigo hejuru y'abantu.
- Gusuzuma iminyururu buri gihe kugira ngo barebe ko hari iminyururu yacitse, ipfundikiye, yangiritse, yagutse, ifite iminkanyari, n'uko ikwiriye.
- Ubushyuhe bukabije cyangwa guhura n'ibidukikije bikoresha imiti nka aside cyangwa ibinyobwa byangiza cyangwa imyuka bishobora kugabanya imikorere y'uruhererekane.
- Ganira n'uwakoze urunigi niba imiyoboro ikora hanze y'ubushyuhe bwagenwe (-40 °F kugeza 400 °F).
- Kuraho umugozi kuri serivisi niba ubunini bw'igice icyo ari cyo cyose kiri ku muyoboro buri munsi y'agaciro ntarengwa kavuzwe.
- Mu kuvanga ubwoko bw'iminyururu cyangwa ibice, byose bigomba gupimwa ku mubare ntarengwa w'umutwaro w'ibice cyangwa iminyururu ifite amanota make.
- Reba amahitamo yacu y'iminyururu y'ubwikorezi yo mu cyiciro cya 70, hamwe n'iminyururu y'imishumi.
