1.Ngokwendawo yokusetshenziswa
a.Lapho ukhetha isithwali samasondo esifanele, into yokuqala okufanele icatshangelwe yisisindo esithwala isondo. Isibonelo, ezitolo ezinkulu, ezikoleni, ezibhedlela, ezakhiweni zamahhovisi nasemahhotela, iphansi lihle, libushelelezi futhi izimpahla ezihanjiswayo ngokuvamile zilula, okusho ukuthi wonke ama-caster azothwala cishe u-10 kuya ku-140kg. Ngakho-ke, inketho efanelekile isithwali sesondo sokucwenga esakhiwe kusetshenziswa inqubo yokugxiviza epuleti elincanyana lensimbi (2-4mm). Lolu hlobo lwesithwala samasondo lulula, luyagobeka, futhi luthule.
b.Ezindaweni ezinjengamafekthri nezindawo zokugcina izimpahla lapho ukuthutha kwempahla kuvame kakhulu futhi umthwalo usinda (280-420kg), sincoma ukusebenzisa isithwala samasondo esenziwe ngepuleti lensimbi eliwugqinsi elingu-5-6mm.
c.Uma isetshenziselwa ukuthwala izinto ezisindayo ezifana nalezo ezivame ukutholakala ezimbonini zendwangu, ezimbonini zezimoto, noma ezimbonini zemishini, ngenxa yomthwalo omkhulu kanye nebanga elide lokuhamba, i-caster ngayinye kufanele ikwazi ukuthwala u-350-1200kg, futhi yenziwe kusetshenziswa i-8-12mm yensimbi ewugqinsi othwala amasondo ensimbi. Isithwali samasondo esinyakazayo sisebenzisa ibhodi lendiza, futhi ibhola lifakwa epuletini elingezansi, okuvumela i-caster ukuthi ithwale umthwalo osindayo ngenkathi isalondoloze ukujikeleza okuguquguqukayo kanye nokumelana nomthelela. Sincoma ukusebenzisa amasondo e-caster enziwe enayiloni eqinisiwe engenisiwe (PA6) super polyurethane noma irabha. Ngokusekelwe ezidingweni ezithile zokufaka isicelo, ingaphinda ifakwe uthayela noma ifuthwe ngomuthi wokumelana nokugqwala, futhi inikezwe umklamo wokuvimbela omazombezombe.
d.Izindawo ezikhethekile: izindawo ezibandayo neziphezulu zokushisa zibeka ingcindezi enkulu kuma-casters, futhi emazingeni okushisa aphezulu, sincoma izinto ezilandelayo
· amazinga okushisa aphansi ngaphansi kuka -45℃: polyurethane
· amazinga okushisa aphezulu asondele noma ngaphezulu kuka-230℃: ama-swivel caster akhethekile amelana nokushisa
2.Ngokomthamo wokuthwala
Ngesikhathi sokukhethwa kwamandla okuthwala ama-casters, abasebenzisi kudingeka bacabangele amamajini athile okuphepha. Sisebenzisa amasondo amasondo asetshenziswa kakhulu njengesibonelo, nakuba ukukhetha kufanele kwenziwe ngokusekelwe kulezi zindlela ezimbili ezilandelayo:
a.Ama-casters ama-3 anesisindo sonke: Omunye wabakhangisi kufanele amiswe. Le ndlela ilungele ukusetshenziswa lapho ama-casters ethwala umfutho omkhulu phezu kwezimo ezimbi zomhlaba ngenkathi kuthuthwa impahla noma okokusebenza, ikakhulukazi ezilinganisweni ezinkulu, ezisindayo eziphelele zesisindo.
b.Ama-casters angu-4 anesisindo esiphelele se-120%: Le ndlela ifanele izimo zomhlabathi ezinhle, futhi umthelela kuma-casters amancane ngesikhathi sokunyakaza kwempahla noma imishini.
c.Bala umthamo wokuthwala: ukuze ubale umthamo womthwalo odingwa ama-casters, kuyadingeka ukwazi isisindo esibulalayo semishini yokulethwa, umthwalo omkhulu kanye nenani lamasondo e-caster nama-caster asetshenzisiwe. Umthamo womthwalo odingekayo wesondo le-caster noma i-caster ubalwa ngale ndlela elandelayo:
T= (E+Z)/M×N
---T= isisindo sokulayisha esidingekayo sesondo le-caster noma i-caster
---E= i-deadweight yemishini yokulethwa
---Z= umthamo omkhulu
---M= inani lamasondo e-caster nama-caster asetshenzisiwe
---N= Isici sokuphepha (cishe 1.3 - 1.5).
Kufanele kuqashelwe amacala lapho abalingisi bezovezwa inani elibalulekile lomthelela. Akufanele kuphela kukhethwe i-caster enamandla okuthwala umthwalo omkhulu, kodwa nezakhiwo zokuvikela umthelela eziklanywe ngokukhethekile kufanele zikhethwe. Uma kudingeka ibhuleki, kufanele kukhethwe amabhuleki anebhuleki elilodwa noma amabili.
· amazinga okushisa aphansi ngaphansi kuka -45℃: polyurethane
