Waba utwara imashini, koresha iminyururu ikurura, cyangwa uri muruganda rwo gutema ibiti, ni ngombwa kumenya imipaka yimikorere yiminyururu ukoresha. Iminyururu ifite imipaka yumurimo ntarengwa- cyangwa WLL- hafi imwe mumbaraga zabo zo gucika (ingano yingufu iminyururu ishobora kwihanganira mbere yo kumeneka).
Urwego rwumunyururu na diameter bigena imipaka yimikorere yumurongo. Urunigi rwanditseho urwego nubunini kuburyo ushobora kumenya WLL yayo ukoresheje iyi mbonerahamwe.
2. Ubwoko bw'urunigi
Icyiciro cya 30 ni urwego rwinshi, urwego rwubukungu. Azwi kandi nka Grade 30 Proof Coil Chain, abantu bakoresha iki gicuruzwa mubikorwa bitandukanye nakazi, harimo kubaka urumuri, iminyururu, ndetse no munganda zo mu nyanja. Ntabwo ari umutekano wo guterura hejuru. Urwego rwa 30 urunigi rwanditseho 3, 30, cyangwa 300.
Yitwa kandi Urwego rwa 43 rwo hejuru Urunigi cyangwa Urwego rwa 43 Tow Urunigi, ibi birasanzwe mubikorwa byo gukurura no gutema ibiti. Ntuzigere ukoresha urunigi kugirango uzamure hejuru. Uyu munyururu urimo ibishushanyo bishushanyije ukoresheje 43 cyangwa G4.
Urunigi rwo gutwara abantu bo mu cyiciro cya 70, nanone rwitwa "Urunigi rw'amakamyo yo mu cyiciro cya 70," rukora mu gushaka imizigo yo gutwara umuhanda. Ntuzigere ukoresha urunigi kugirango uzamure hejuru. Urunigi rurimo ibishushanyo bishushanyije ukoresheje 7, 70, cyangwa 700.
Icyiciro cya 80 Alloy Chain ikora hejuru yo guterura hejuru kubera igishushanyo cyayo gitunganijwe. Abantu bakunze gukoresha ubu bwoko bwurunigi nkurwego rukomeye rukurura urunigi. Urwego rwa 80 urunigi rurimo ibishushanyo bishushanyije ukoresheje 8, 80, cyangwa 800.
Ufatwa nk'urwego ruhebuje rw'urwego rwiza, rutanga hafi 25% yumurimo urenze urwego rwa 80. Ni byiza guterura hejuru. Urunigi rwo mu cyiciro cya 100 rurimo ibishushanyo byanditseho 10 cyangwa 100.
Igicuruzwa gishya ku isoko, Urwego rwo mu cyiciro cya 120 rukomeye rugera kuri 50% uruta urwego rwa 80 na 20% rukomeye kuruta urwego rwa 100. Irashobora kandi kwihanganira gukuramo kuruta iminyururu ya Grade 80 na Grade 100. Numutekano wo guterura hejuru.
3. Menya byinshi kubyerekeye itandukaniro riri hagati yicyiciro cya 70, 80 na 100 hano:
Ikibazo rusange itsinda ryacu ryo kugurisha ryumva kubakiriya kubyerekeye ibicuruzwa byacu byumunyururu ni "Ni irihe tandukaniro riri hagati yicyiciro cya 70, 80, 100, na 120?" Turasobanura itandukaniro riri hagati yibi byiciro nu munyururu ugomba gukoresha ukurikije ibyo ukeneye.
Icyiciro cya 70 Urunigi
Urwego rwa 70 urwego rukorerwa mubyuma bitunganyirizwa ubushyuhe. Bizwi kandi nka "urunigi rw'amakamyo," abantu bakoresha icyiciro cya 70 nka karuvati kuri gari ya moshi zirenga umuhanda.Ntuzigere ukoresha urunigi kugirango uzamure hejuru.
Ubu bwoko muri rusange buranga chromate irangiza kuburyo byoroshye kumenya. Yujuje kandi irondo rya California Patrol hamwe na DOT ibisabwa. Imikoreshereze y'uruhererekane, usibye ubwikorezi, harimo gukurura, gutema ibiti, amavuta, hamwe no gusaba umutekano.
Uyu munyururu urimo ibishushanyo bishushanyijeho 7, 70, cyangwa 700.
Urunigi 80 ni urunigi rukoreshwa nubushyuhe hamwe nimbaraga nyinshi ugereranije nuburemere. Imbaraga zayo zituma umutekano wo guterura hejuru no guterura. Nibyiza cyane kubikoresha nko gukira, umutekano, n'iminyururu ikurura.
Uru ruhererekane narwo rugenda rusanzwe mu nganda zitwara amakamyo kugira ngo zikore imitwaro iremereye cyane. Kuberako ubu bwoko bwurunigi busanzwe bufite ubwoko bwihariye bwa clevis grab hook, kandi inteko nkizo ntizemewe guterura hejuru.
Uyu munyururu urimo ibishushanyo byanditseho 8, 80, cyangwa 800.
Icyiciro cya 80 Urunigi
Icyiciro cya 100 Urunigi
Icyiciro cya 100 Urunigi nigicuruzwa gishya kandi kiragenda gikundwa cyane nkuwasimbuye urwego rwa 80. Urebye ubuziranenge buhebuje nababikora, butanga hafi 25% yumurimo ntarengwa wo gukora kurenza icyiciro cya 80 kandi ikora kubikorwa byo guterura hejuru.
Abantu benshi bakoresha icyiciro cya 100 hejuru yicyiciro cya 80 kugirango babone imitwaro yuzuye. Urunigi rurimo imbaraga zongerewe nubunini buto butajyanye numurimo wimirimo.
Ariko, kubera ko iyi minyururu isanzwe ifite ubwoko bwihariye bwa clavis grab hook, kandi inteko nkizo ntizemewe guterura hejuru.
Uru ruhererekane rurimo ibishushanyo byanditseho 10, 100, cyangwa 1000.
Icyiciro cya 120 cyicyiciro nacyo nicyiciro gishya cyurwego rwo hejuru, rutanga imbaraga zisumba izindi mu nganda. Imiterere ya kare ihuza uburyo bwo guhuza byinshi hagati yimyanya igaragara kumurongo, bigabanya umuvuduko kumurongo.
Ibi bisobanurwa kumurimo wimirimo uri hejuru ya 50% kurenza icyiciro cya 80, na 20% hejuru yicyiciro cya 100. Urunigi urwego 120 rukora mukuzamura hejuru. Ni ngombwa kumenya ko nkuko hamwe na Grade 80 ihambira inteko zuruhererekane hamwe nicyiciro cya 100 cyo guhambiranya inteko, inteko zumunyururu nazo ntizifite umutekano mukuzamura hejuru bitewe nubwoko bwibikoresho byakoreshejwe.
Ubu bwoko bwurunigi bufite ubururu bwerurutse burangira kugirango bumenyekane byoroshye.
Icyiciro cya 120 Urunigi
Hatitawe ku bwoko bw'urunigi, bose bagomba kubahiriza ibipimo byashyizweho n'ishyirahamwe ry'igihugu ry'abakora iminyururu (NACM), birimo:
- Ntuzigere utwara cyangwa guhagarika imizigo yazamuye abantu.
- Kugenzura iminyururu buri gihe kubice, gouges, kwambara, kurambura, nik, kandi bikwiranye.
- Ubushyuhe bukabije cyangwa guhura nibidukikije bikora imiti nka acide cyangwa amavuta yangirika cyangwa imyotsi bishobora kugabanya imikorere yumunyururu.
- Baza uwakoze urunigi niba iminyururu izakorera hanze yubushyuhe bwateganijwe (-40 ° F kugeza 400 ° F).
- Kuraho urunigi muri serivisi niba umubyimba ku gice icyo aricyo cyose uhuza uri munsi yurutonde ntarengwa.
- Iyo kuvanga urunigi cyangwa ubwoko bwibigize, byose bigomba gutondekwa kumurimo wimirimo yimikorere yibintu biri hasi cyane.
- Reba ibyo twahisemo byo mu cyiciro cya 70 cyo gutwara abantu, hamwe nu munyururu.
