1. Umda wokuLawulwa kokuSebenza kwiiNgxoxo zeNsimbi eziLungeleleyo
Nokuba uthutha oomatshini, usebenzisa amatyathanga okutsala, okanye ukwishishini lokugawulwa kwemithi, kubalulekile ukwazi imida yomthwalo wokusebenza wekhonkco olisebenzisayo.Amatyathanga anomda womthwalo osebenzayo- okanye i-WLL- malunga nesinye kwisinye kwikhefu lamandla awo (ubungakanani bamandla amatyathanga anokumelana nawo phambi kokuba aqhawuke).
Ibakala lekhonkco kunye nedayamitha imisela umda womthwalo wokusebenza wekhonkco.Itsheyini ifakwe kuzo zombini ibakala kunye nobungakanani ukuze ukwazi ukumisela iWLL yayo usebenzisa le tshati.
2. Iintlobo zekhonkco
IBanga lama-30 litsheyini elinenjongo ezininzi, elinoqoqosho.Ikwaziwa njenge-Grade 30 Proof Coil Chain, abantu basebenzisa le mveliso kumashishini ahlukeneyo kunye nemisebenzi, kubandakanywa ulwakhiwo olulula, i-barrier chain, kunye noshishino lwaselwandle.Ayikhuselekanga ekuphakamiseni phezulu.Itsheyini yeBakala 30 ibhalwe kusetyenziswa u-3, 30, okanye 300.
Ikwabizwa ngokuba yiBanga lama-43 loVavanyo oluPhezulu okanye iBanga lama-43 iTow Chain, oku kuxhaphakile kumashishini okutsala nokugawula imithi.Ungaze usebenzise eli khonkco xa uphakamisa umphezulu.Eli khonkco libandakanya uyilo olufakwe kwi-43 okanye i-G4.
ICandelo lezoThutho zeBanga lama-70, elikwabizwa ngokuba yi-"Grade 70 Truckers Chain," lisebenza ekuqinisekiseni imithwalo yokuthuthwa phezu kwendlela.Ungaze usebenzise elitsheyina nakuphi na ukunyusela phezulu.Eli khonkco libandakanya uyilo olufakwe kwi-7, 70, okanye i-700.
I-Alloy Chain yeBakala 80 isebenzela ukunyusela phezulu ngenxa yoyilo lwayo olunobushushu.Abantu baqhele ukusebenzisa olu hlobo lwetsheyini njengetsheyini yokutsala nzima.Ikhonkco leBakala 80 libandakanya uyilo olugxininisiweyo kusetyenziswa u-8, 80, okanye 800.
Ithathwa njengekhonkco lomgangatho weprimiyamu, ibonelela ngomda womthwalo ongaphezulu wama-25% ngaphezulu kwekhonkco leBanga lama-80.Ikhuselekile ekuphakamiseni phezulu.Amatyathanga eBakala 100 abandakanya iidizayini ezibhalwe nge-10 okanye i-100.
Imveliso entsha emarikeni, ikhonkco leBanga le-120 lomelele ukuya kutsho kuma-50% kunekhonkco leBakala 80 kunye ne-20% yomelele kunekhonkco leBanga le-100.Ikwayakwazi ukumelana nokukrala kunawo omabini amatyathanga eBanga lama-80 kunye neBanga le-100.Ikhuselekile kwizinyusi eziphezulu.
3. Funda kabanzi malunga nomahluko phakathi kwamabanga 70, 80 kunye ne-100 apha:
Umbuzo oqhelekileyo oviwa liqela lethu leentengiso kubathengi malunga neemveliso zethu zekhonkco "Nguwuphi umahluko phakathi kwebanga lama-70, 80, 100, kunye nekhonkco le-120?"Sichaza umahluko phakathi kwezi ndidi kunye nokuba yeyiphi imixokelelwane omele uyisebenzise ngokweemfuno zakho.
IBakala 70 Ikhonkco
Ikhonkco leBanga le-70 lenziwa ngentsimbi yekhabhoni ephethwe ngubushushu.Ekwaziwa ngokuba "yityathanga lamalori," abantu basebenzisa ibanga lama-70 njengezinto zokubopha kwiitreyila ezihamba endleleni.Ungaze usebenzise eli khonkco xa uphakamisa umphezulu.
Olu hlobo lubonisa ukugqitywa kwechromate yegolide ukuze kube lula ukuqaphela.Ikwadibana neCalifornia Highway Patrol kunye neemfuno zeDOT.Ukusetyenziswa kweli tsheyini, ngaphandle kwezothutho, kubandakanya ukutsala, ukugawulwa kwemithi, izixhobo zeoyile, kunye nezicelo zokhuseleko.
Eli khonkco libandakanya uyilo olufakwe kwi-7, 70, okanye 700.
Itsheyina le-80 yitsheyini yentsimbi ephethwe bubushushu enamandla amakhulu kumlinganiselo wobunzima.Amandla ayo ayenza ikhuseleke ekuphakamiseni phezulu kunye nokuphakamisa izilingi.Ikwalungile kusetyenziso olunjengokubuyisela, ukhuseleko, kunye namatyathanga okutsala.
Eli khonkco liya lixhaphake ngakumbi kushishino lwelori olune-flatbed ukukhusela imithwalo enzima kwimizi-mveliso.Ngenxa yokuba ezi ntlobo zamatyathanga ngokubanzi zixhotyiswe ngohlobo oluthile lwe-clevis grab hook, kwaye iindibano zekhonkco ezinjalo azivunywanga ukuba ziphakanyiswe phezulu.
Eli khonkco libandakanya uyilo olufakwe kwi-8, 80, okanye i-800.
IBakala 80 Ikhonkco
Grade 100 Chain
Itsheyini yeBanga le-100 yimveliso entsha kwaye iya isanda ngokuduma njengokutshintsha ikhonkco lebanga lama-80.Ithathwa njengomgangatho wepremiyamu ngabavelisi, ibonelela malunga ne-25% ephezulu yomthwalo womthwalo wokusebenza kunebakala lama-80 kwaye isebenzela izicelo zokunyuselwa phezulu.
Abantu abaninzi basebenzisa ibanga le-100 ngaphezulu kwebanga lama-80 ukukhusela imithwalo ecaba.Eli khonkco liqulethe amandla okongeziweyo kunye nobukhulu obuncinci obungahambelani nomda womthwalo osebenzayo.
Nangona kunjalo, ngenxa yokuba la matyathanga ngokubanzi axhotyiswe ngohlobo oluthile lwe-clevis grab hook, kwaye ezo ndibano zekhonkco azivunywanga ukuba ziphakanyiswe phezulu.
Eli khonkco libandakanya uyilo olufakwe kwi-10, 100, okanye i-1000.
Itsheyini yeBanga le-120 ikwaludidi olutsha lwetyathanga lentsebenzo ephezulu, enika awona mandla aphezulu kushishino.Isitayela sokudibanisa isikwele senza uqhagamshelwano olungakumbi phakathi kweendawo zokuthwala kwiikhonkco, ezinciphisa uxinzelelo kwikhonkco.
Oku kuthetha ukuba imida yomthwalo wokusebenza engaphezulu nge-50% kunebakala lama-80, kunye ne-20% ngaphezulu kwebakala le-100. I-Chain grade 120 isebenzela ukunyuselwa phezulu.Kubalulekile ukuqaphela ukuba njengakwiBanga le-80 lokubopha ikhonkco leendibano zekhonkco kunye neBanga le-100 lokubopha amatsheyina adityanisiweyo, iiassemblies zamatsheyini nazo azikhuselekanga ekuphakamiseni phezulu ngenxa yohlobo lweehuku ezisetyenzisiweyo.
Olu hlobo lwekhonkco lunokugqiba okuluhlaza okwesibhakabhaka okuqaqambileyo ukwenza ukuba baqapheleke ngokulula.
IBanga le-120 Ikhonkco
Kungakhathaliseki ukuba luhlobo luni lwekhonkco, bonke kufuneka babambelele kwimigangatho ebekwe nguMbutho weSizwe waBavelisi beChain (NACM), equka:
- Ungaze uthuthe okanye umise imithwalo ephakanyisiweyo phezu kwabantu.
- Ukuhlola amatyathanga ngamaxesha athile ukuze kubonwe iintanda, iigouges, ukunxitywa, ubude, iziqhulo, kunye nokufaneleka.
- Ubushushu obugqithisileyo okanye ukuchanabeka kwindawo esebenza ngemichiza efana neeasidi okanye ulwelo oludlekayo okanye umsi kunokunciphisa ukusebenza kwetsheyini.
- Qhagamshelana nomenzi wetsheyini ukuba amatsheyini aya kusebenza ngaphandle komgangatho wobushushu obucetyiswayo (-40 °F ukuya kuma-400 °F).
- Susa ikhonkco kwinkonzo ukuba ubukhulu bayo nayiphi na indawo kwikhonkco bungaphantsi kwexabiso elincinci elidwelisiweyo.
- Xa ukuxuba ikhonkco okanye iintlobo zecandelo, zonke kufuneka zilinganiswe kumda womthwalo wokusebenza wecandelo elinomlinganiselo ophantsi okanye ikhonkco.
-Khangela esikukhethileyo kwibanga lama-70 ikhonkco lezothutho, kunye nezilingi zamatsheyina.
