1.Kurikije ibidukikije bikoreshwa
a.Mugihe uhisemo gutwara ibiziga bikwiye, ikintu cya mbere ugomba kwitaho ni uburemere bwibiziga.Kurugero, muri supermarket, amashuri, ibitaro, inyubako zo mu biro na hoteri, hasi ni nziza, yoroshye kandi ibicuruzwa bikikijwe hirya no hino usanga byoroshye, bivuze ko buri caster izatwara hafi 10 kg 140.Kubwibyo, amahitamo akwiye ni icyuma gitwara ibiziga byakozwe hakoreshejwe uburyo bwo gutera kashe ku cyuma cyoroshye (2-4mm).Ubu bwoko bwikiziga cyoroshye, cyoroshye, kandi kiracecetse.
b.Ahantu nkinganda nububiko aho usanga imizigo ikunze kugaragara kandi umutwaro uremereye (280-420kg), turasaba ko dukoresha umutwaro wibiziga bikozwe mubyuma bya 5-6mm.
c.Niba ikoreshwa mugutwara ibintu biremereye nkibisanzwe biboneka mu nganda z’imyenda, mu nganda z’imodoka, cyangwa mu nganda z’imashini, kubera umutwaro munini hamwe n’urugendo rurerure rwo kugenda, buri caster igomba kuba ishobora gutwara ibiro 350-1200, kandi bigakorwa hifashishijwe 8 -12mm yububiko bwibyuma bitwara ibiziga.Umwikorezi wikiziga cyimukanwa akoresha umupira windege, kandi umupira ushyirwa kumasahani yo hepfo, bigatuma caster yikorera umutwaro uremereye mugihe ikomeza guhinduranya no guhangana ningaruka.Turasaba gukoresha ibiziga bya caster bikozwe muri nylon yongerewe imbaraga (PA6) super polyurethane cyangwa rubber.Ukurikije ibyifuzo byihariye bikenewe, birashobora kandi gushyirwaho imbaraga cyangwa guterwa imiti yo kurwanya ruswa, ndetse no guhabwa igishushanyo mbonera cyo gukumira.
d.Ibidukikije bidasanzwe: ahantu hakonje nubushyuhe bwo hejuru hashyira impungenge nyinshi kuri casters, kandi kubushyuhe bukabije, turasaba ibikoresho bikurikira
· Ubushyuhe buke munsi ya -45 ℃: polyurethane
· Ubushyuhe bwo hejuru hafi cyangwa hejuru ya 230 ℃: ibyuma bidasanzwe birwanya ubushyuhe bwa swivel
2. Ukurikije ubushobozi bwo gutwara
Mugihe cyo gutoranya ubushobozi bwo gutwara ibintu, abakoresha bakeneye kuzirikana imipaka yihariye yumutekano.Dukoresha cyane ibiziga bine bikoreshwa nkurugero, nubwo guhitamo bigomba gukorwa hashingiwe kuburyo bubiri bukurikira:
a.Abakinnyi 3 bafite uburemere bwose: Umwe mubakinnyi agomba guhagarikwa.Ubu buryo burakwiriye kubisabwa aho abaterankunga bafite imbaraga nyinshi kubutaka bubi mugihe bagenda ibicuruzwa cyangwa ibikoresho, cyane cyane mubunini, buremereye buringaniye.
b.Imashini 4 zifite uburemere bwa 120%: Ubu buryo bukwiranye nubutaka bwiza bumeze neza, kandi ingaruka kuri casters ni nto mugihe cyo gutwara ibicuruzwa cyangwa ibikoresho.
c.Kubara ubushobozi bwo gutwara: kugirango ubare ubushobozi bwimitwaro ikenerwa nabakinnyi, birakenewe kumenya uburemere bwibikoresho byo kugemura, umutwaro ntarengwa n'umubare w'inziga za caster na casters zikoreshwa.Ubushobozi bwimitwaro isabwa kumuziga ya caster cyangwa caster ibarwa kuburyo bukurikira:
T = (E + Z) / M × N.
--- T = uburemere bwo gupakira bukenewe kubiziga bya caster cyangwa caster
--- E = uburemere bwibikoresho byo gutanga
--- Z = umutwaro ntarengwa
--- M = umubare wibiziga bya caster na casters byakoreshejwe
--- N = Impamvu z'umutekano (hafi 1.3 - 1.5).
Hagomba kwitonderwa kubibazo aho abaterankunga bazahura ningaruka zikomeye.Ntabwo hagomba gusa guhitamo caster ifite ubushobozi bunini bwo gutwara imizigo, ariko hagomba no guhitamo uburyo bwihariye bwo kurinda ingaruka.Niba feri ikenewe, casters ifite feri imwe cyangwa ebyiri igomba guhitamo.
· Ubushyuhe buke munsi ya -45 ℃: polyurethane
