Mayelana Nokukhethwa Kwezakhi

1. Impahla ye-wheeli: impahla esetshenziselwa ama-wheeli emsebenzini ohlanzekile ivamise ukuba yi-nylon, polyurethane, kanye ne-super artificial rubber (ngokuvamile, ama-wheeli ejazi elijwayelekile, ikakhulukazi amnyama, awasetshenziswanga, ngoba ahlola phansi futhi kulula ukuwa). Phakathi kwalezi zimpahla ezintathu, i-nylon iyona eqinile kakhulu, kulula ukuyiphusha, kodwa umsindo uphakamisa, okungase kubangele ukulimala phansi; i-super artificial rubber (eyaziwa ngokuthi i-silent wheel) iyona ethambile kakhulu, ayinomsindo uma iphushwa, futhi ayizukulimaza phansi, kodwa ibanga umthwalo; i-polyurethane ikhuluma phakathi kwalezi ezimbili, ngakho-ke impahla ye-polyurethane ivamise ukusetshenziswa, futhi ubunzima bayo bujwayelekile.

2. Impahla ye-caster bracket: i-bracket ivamise ukwenziwa nge-carbon steel kanye ne-galvanized. Izindleko ze-stainless steel bracket ziphezulu. Kungakhethwa ngokuya ngendawo yokusetshenziswa nezidingo. Sivame ukuncoma ukusebenzisa ama-bracket e-stainless steel.

3. Umbala wezinsimbi: i-nylon inemibala emhlophe, emnyama nempunga, phakathi kwazo umhlophe usebenza kakhulu; i-polyurethane inombala obomvu, ompunga nblack, ngokuvamile kukhethwa obomvu nempunga; i-super artificial rubber ivamise ukuba mpunga kuphela.

4. Ibhola le-casters: kunezibhakabhaka, izikhonkwane, ama-bearings epulasitiki, ama-casters alula (ikhasi ngalinye le-caster liphatha ngaphansi kuka-150kg) ngokuvamile usebenzisa ama-ball bearings, okuyinto elula kakhulu ukuyiphusha; ama-needle roller (ikholomu) ama-bearings ngokuvamile afanele ama-casters anzima, futhi amandla awo okuphatha aqinile, kodwa ukungqubuzana kukhulu, futhi kuyaphazamiseka ukuyiphusha; ama-bearings epulasitiki (ama-sleeves) ngokuvamile asetshenziswa ndawonye nezinsika zensimbi engagqwali, ezivimbela ukugqwala futhi zingahlanzwa, kodwa uma kuqhathaniswa nama-ball bearings, isikhala sikhulu futhi kuyaphazamiseka.

5. Amabhuleki ezinsimbi: kukhona amabhuleki aseduze, amabhuleki okunyathela, kanye namabhuleki aphelele. Amabhuleki aseduze afakwe phakathi kwesigaba se-wheeli; amabhuleki okunyathela kanye namabhuleki aphelele afakwe engxenyeni ephezulu ye-wheeli; amabhuleki aseduze kanye namabhuleki okunyathela angabamba kuphela i-wheeli. Ukuphenduka kwe-radial, ibhande lingaphinde liphenduke; ibhuleki ephelele (eyaziwa nangokuthi ibhuleki eliphindwe kabili), lapho unyawo olulodwa luphakanyiswa, i-wheeli ibhujiswa ngokuqondile kanye nokuphenduka kwe-bracket ngesikhathi esifanayo. Ngokuvamile, amabhuleki okunyathela asetshenziswa kakhulu, kodwa siphakamisa ukuthi njengoba udinga ukusebenzisa amabhuleki, kungcono ukusebenzisa amabhuleki aphelele.

Izing above yizinto ezisemqoka ezijwayelekile zokukhetha i-caster. Ngokuqinisekile, kunezinto eziningi nezimibala ze-casters, futhi kunezixazululo ezahlukene ngokuya ngezidingo ezahlukene zokusetshenziswa.
