Mayelana Nokukhethwa Kwezakhi

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

2. Impahla ye-caster bracket: i-bracket ivamise ukwenziwa ngensimbi ye-carbon kanye ne-galvanized. Izindleko ze-bracket ye-stainless steel ziphakeme. Ingakhethwa 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, ngokujwayelekile kukhethwa obomvu nempunga; i-super artificial rubber ngokujwayelekile inombala ompunga kuphela.

4. Ibhola le-casters: kunezibhakela, izikhonkwane, izibhakela ze-plastiki zobunjiniyela, ama-casters alula (ikhasi ngalinye le-caster liphatha okungaphansi kuka-150kg) ngokuvamile usebenzisa izibhakela zebhola, okuyinto elula kakhulu ukuyiphusha; izibhakela ze-needle roller (ikhompyutha) ngokuvamile zifanele ama-casters anzima, futhi amandla azo okuphatha aqinile, kodwa ukungqubuzana kukhulu, futhi kuyinselele ukuyiphusha; izibhakela ze-plastiki (ama-sleeves) ngokuvamile zisetshenziswa ngokuhlanganyela nezibambo ze-stainless steel, ezivikeleke ekugqokeni futhi zingahlanzwa, kodwa uma kuqhathaniswa nezibhakela zebhola, isikhala sikhulu futhi kuyinselele.

5. Amabhuleki wezikhwama: kukhona amabhuleki aseduze, amabhuleki okunyathela, kanye namabhuleki aphelele. Amabhuleki aseduze afakwe phakathi kwesigaba sesikhwama; amabhuleki okunyathela kanye namabhuleki aphelele afakwe engxenyeni ephezulu yesikhwama; amabhuleki aseduze kanye namabhuleki okunyathela angabamba kuphela isikhwama. Ukuphenduka kwe-radial, ibhuleki ingaphinde iphenduke; ibhuleki ephelele (ebizwa nangokuthi ibhuleki eliphindwe kabili), uma unyawo olulodwa lufakwe, isikhwama sihamba ngokuqondile futhi ukuhamba kwe-bracket kuyabambeka ngesikhathi esifanayo. Ngokuvamile, amabhuleki okunyathela asetshenziswa kakhulu, kodwa siphakamisa ukuthi njengoba udinga ukusebenzisa amabhuleki, kungcono ukusebenzisa amabhuleki aphelele.

Okukhuluma ngenhla kuyizinto ezisemqoka ezijwayelekile zokukhetha i-caster. Ngokuqinisekile, kunezinto eziningi nezimibala ze-casters, futhi kunezihlanganisi eziningi ezihlukene ngokuya ngezidingo ezihlukene zokusetshenziswa.
