1. Ngokwemeko-bume yokusetyenziswa
a.Xa ukhetha isithuthi esifanelekileyo sokuthwala amavili, into yokuqala ekufuneka uyiqwalasele bubunzima besithuthi esithwala amavili. Umzekelo, kwiivenkile ezinkulu, ezikolweni, ezibhedlele, kwizakhiwo zeeofisi nakwiihotele, umgangatho ulungile, uthambile kwaye iimpahla ezihanjiswayo zihlala zilula, oko kuthetha ukuba isithuthi ngasinye siya kuthwala malunga ne-10 ukuya kwi-140kg. Ke ngoko, ukhetho olufanelekileyo yisithuthi esithwala amavili esenziwe ngenkqubo yokunyathela kwipleyiti yesinyithi esincinci (2-4mm). Olu hlobo lwesithuthi esithwala amavili lulula, luguquguquka, kwaye alunamsindo.
b.Kwiindawo ezinje ngeefektri nakwiindawo zokugcina impahla apho ukuthuthwa kwemithwalo kuxhaphake kakhulu kwaye umthwalo unzima (280-420kg), sicebisa ukusebenzisa isithuthi esithwala amavili esenziwe ngepleyiti yentsimbi enobukhulu obuyi-5-6mm.
c.Ukuba isetyenziselwa ukuthwala izinto ezinzima ngakumbi ezifana nezo zifumaneka rhoqo kwiifektri zelaphu, iifektri zeemoto, okanye iifektri zoomatshini, ngenxa yomthwalo omkhulu kunye nomgama omde wokuhamba, i-caster nganye kufuneka ikwazi ukuthwala i-350-1200kg, kwaye yenziwe kusetyenziswa i-carrier yevili yentsimbi enobukhulu obuyi-8-12mm. I-carrier yevili eshukumayo isebenzisa i-plane ball bearing, kwaye i-ball bearing ifakwe kwipleyiti esezantsi, ivumela i-caster ukuba ithwale umthwalo onzima ngelixa igcina ukujikeleza okuguquguqukayo kunye nokumelana nempembelelo. Sicebisa ukusebenzisa amavili e-caster enziwe nge-nylon eqinisiweyo (PA6) super polyurethane okanye irabha evela kwamanye amazwe. Ngokusekelwe kwiimfuno ezithile zokusetyenziswa, ingagalelwa okanye itshizwe ngonyango lokumelana nokugqwala, kunye noyilo lokuthintela ukujija.
d.Iindawo ezikhethekileyo: iindawo ezibandayo nezishushu kakhulu zibeka uxinzelelo olukhulu kwii-casters, kwaye xa kushushu kakhulu, sicebisa ezi zinto zilandelayo
· amaqondo obushushu aphantsi angaphantsi kwe -45℃: i-polyurethane
· amaqondo obushushu aphezulu akufutshane okanye angaphezulu kwama-230℃: ii-casters ezikhethekileyo ezijikelezayo ezingatshiyo ubushushu
2.Ngokutsho komthamo wokuthwala
Ngexesha lokukhetha umthamo wokuthwala we-casters, abasebenzisi kufuneka baqwalasele imida ethile yokhuseleko. Sisebenzisa ii-casters ezine-wheel casters ezisetyenziswa kakhulu njengomzekelo, nangona ukhetho kufuneka lwenziwe ngokusekelwe kwezi ndlela zimbini zilandelayo:
a.Ii-casters ezi-3 ezinobunzima obupheleleyo: Elinye la ma-casters kufuneka lixhonywe. Le ndlela ifanelekile kwizicelo apho ama-casters ethwala amandla amakhulu xa umhlaba uphantsi xa ehambisa impahla okanye izixhobo, ingakumbi xa zizonke zinobunzima obukhulu nobunzima.
b.Ii-casters ezi-4 ezinobunzima obupheleleyo be-120%: Le ndlela ifanelekile kwiimeko zomhlaba ezilungileyo, kwaye impembelelo kwii-casters incinci ngexesha lokuhamba kweempahla okanye izixhobo.
c.Bala umthamo wokuthwala: ukuze kubalwe umthamo womthwalo ofunekayo ngabathuthi, kuyimfuneko ukwazi ubunzima bezixhobo zokuhambisa, umthwalo ophezulu kunye nenani lamavili e-caster kunye nabathuthi abasetyenzisiweyo. Umthamo womthwalo ofunekayo kwivili le-caster okanye i-caster ubalwa ngolu hlobo lulandelayo:
T= (E+Z)/M×N
---T= ubunzima bomthwalo obufunekayo kwivili le-caster okanye i-caster
---E= ubunzima obungapheliyo bezixhobo zokuhambisa
---Z= umthwalo ophezulu
---M= inani lamavili e-caster kunye nee-caster ezisetyenzisiweyo
---N= Into yokhuseleko (malunga ne-1.3 - 1.5).
Kufuneka kuqwalaselwe iimeko apho ii-caster ziya kuvezwa kumonakalo omkhulu. Akufuneki kukhethwe i-caster enomthwalo omkhulu kuphela, kodwa kufuneka kukhethwe nezakhiwo zokukhusela impembelelo eziyilwe ngokukodwa. Ukuba kufuneka i-brake, ii-caster ezinee-brake enye okanye ezimbini kufuneka zikhethwe.
· amaqondo obushushu aphantsi angaphantsi kwe -45℃: i-polyurethane
