1.Ngokwemeko yokusetyenziswa
a.Xa ukhetha isithwala ivili esifanelekileyo, into yokuqala ekufuneka uyithathele ingqalelo bubunzima bomthwalo wevili.Umzekelo, kwiivenkile ezinkulu, ezikolweni, ezibhedlele, kwizakhiwo zeofisi kunye neehotele, umgangatho ulungile, ugudileyo kwaye iimpahla ezijikelezayo zihlala zikhaphukhaphu, okuthetha ukuba i-caster nganye iya kuthwala malunga ne-10 ukuya kwi-140kg.Ngoko ke, ukhetho olufanelekileyo sisithwala isondo se-plating esakhiwe ngokusebenzisa inkqubo yokunyathela kwi-plate yensimbi encinci (2-4mm).Olu hlobo lokuthwala ivili lulula, lubhetyebhetye, kwaye luthule.
b.Kwiindawo ezifana neefektri kunye neendawo zokugcina iimpahla apho ukuhamba kwempahla kuxhaphakileyo kwaye umthwalo unzima (280-420kg), sincoma ukusebenzisa i-wheel carrier eyenziwe nge-5-6mm yentsimbi yentsimbi.
c.Ukuba isetyenziselwa ukuthwala izinto ezinzima ezifana nezo ziqhele ukufunyanwa kwimizi-mveliso yamalaphu, kwimizi-mveliso yeemoto, okanye kwimizi-mveliso yoomatshini, ngenxa yomthwalo omkhulu kunye nomgama omde wokuhamba, i-caster nganye kufuneka ikwazi ukuthwala i-350-1200kg, kwaye yenziwe kusetyenziswa i-8. -12mm etyebileyo ipleyiti yentsimbi umthuthi ivili.Umqhubi wevili oshukumayo usebenzisa inqwelo yebhola yendiza, kwaye ibhola yebhola ifakwe kwi-plate ephantsi, ivumela i-caster ukuba ithwale umthwalo onzima ngelixa igcina ukujikeleza okuguquguqukayo kunye nokuchasana kwempembelelo.Sincoma ukusebenzisa amavili e-caster enziwe ngenayiloni eqinisiwe evela kumazwe angaphandle (PA6) super polyurethane okanye irabha.Ngokusekwe kwiimfuno ezithile zesicelo, inokuphinda igalelwe okanye itshizwe ngonyango lokumelana nomhlwa, kwaye inikwe uyilo lokuthintela olujikajikayo.
d.Iindawo ezikhethekileyo: iindawo ezibandayo kunye nobushushu obuphezulu zibeka uxinzelelo olukhulu kwii-casters, kwaye kumaqondo obushushu agqithisileyo, sincoma ezi zinto zilandelayo.
· amaqondo obushushu aphantsi ngaphantsi -45℃: polyurethane
· amaqondo obushushu aphezulu asondele okanye ngaphezulu kwe-230℃: ii-swivel casters ezikhethekileyo zokumelana nobushushu
2.Ngokomthamo wokuthwala
Ngexesha lokukhethwa kwamandla okuthwala ama-casters, abasebenzisi kufuneka bathathele ingqalelo imida ethile yokhuseleko.Sisebenzisa ezona zixhaphakileyo iicaster ezinevili njengomzekelo, nangona ukhetho kufuneka lwenziwe ngokusekwe kwezi ndlela zimbini zilandelayo:
a.Ii-Casters ezi-3 ezithwele ubunzima bonke: Omnye wabakhangisi kufuneka anqunyanyiswe.Le ndlela ifanelekile kwizicelo apho i-casters ithwala umfutho omkhulu phezu kweemeko ezimbi zomhlaba ngelixa uhambisa iimpahla okanye izixhobo, ngokukodwa kwimilinganiselo emikhulu, enzima kakhulu.
b.I-4 casters ethwele ubunzima obupheleleyo be-120%: Le ndlela ifanelekile kwiimeko zomhlaba ezilungileyo, kwaye impembelelo kwi-casters incinci ngexesha lokuhamba kwempahla okanye izixhobo.
c.Bala umthamo wokuthwala: ukwenzela ukubala umthamo womthwalo ofunekayo kwii-casters, kuyimfuneko ukwazi i-deadweight yezixhobo zokuhambisa, umthwalo ophezulu kunye nenani lamavili e-caster kunye ne-casters esetyenzisiweyo.Umthamo womthwalo ofunekayo kwivili lecaster okanye icaster ubalwa ngolu hlobo lulandelayo:
T= (E+Z)/M×N
---T= ubunzima bokulayisha obufunekayo kwivili lecaster okanye icaster
---E= ubunzima bezixhobo zokuhambisa
---Z= ubukhulu bomthwalo
---M= inani lamavili ecaster kunye neecaster ezisetyenzisiweyo
---N= Into yokhuseleko (malunga ne-1.3 - 1.5).
Ingqalelo kufuneka ihlawulwe kumatyala apho i-casters iya kuboniswa kwisixa esibalulekileyo sempembelelo.Akufuneki kuphela i-caster enomthamo omkhulu wokuthwala umthwalo okhethiweyo, kodwa izakhiwo ezikhethekileyo zokukhusela impembelelo kufuneka zikhethwe.Ukuba i-brake iyadingeka, ii-casters ezineziqhoboshi enye okanye ezimbini kufuneka zikhethwe.
· amaqondo obushushu aphantsi ngaphantsi -45℃: polyurethane
