Caster ndi chofunika chowonjezera cha chonyamulira, ambiri chonyamulira mwina m'manja kapena kukokedwa, inu mu kusankha casters, ayenera zochokera kugwiritsa ntchito zipangizo ndi ntchito yeniyeni zachilengedwe, kusankha casters lolingana.
Choyamba, mukasankha oponya, muyenera kuganizira mtundu wanji wa pansi omwe mukugwiritsa ntchito powonekera? Ndi konkriti kapena marble? Kodi pansi ndi lofewa kapena lolimba? Kodi mumafunikira chitetezo chapamwamba chapansi?
Kutengera momwe amagwiritsidwira ntchito, timalimbikitsa nayiloni kapena polyurethane (TPU) yamphamvu kwambiri yapansi panthaka, ndi mawilo a rabara kapena polyurethane (PU) ya miyala ya miyala ya m'nyumba kapena pansi.
Kusintha gudumu pamwamba zinthu za oponya anu kudzakuthandizani kukulitsa zothandiza.
Chachiwiri. Kodi kulemera kwake ndi liwiro la ntchito ndi chiyani? Mukasuntha mwachangu, mphamvu zolemetsa zomwe oponya amafunikira. Caster diameter, m'lifupi ndi zinthu zonse zimakhudza kuchuluka kwa kulemera komwe caster imatha kunyamula pa liwiro lalitali kapena lotsika.
Kuti mudziwe kuchuluka kwa katundu wofunikira pa choyika chilichonse pangolo, gawani kuchuluka kwa ngolo ndi kuchuluka kwa oponya. Kenako chulukitsani zotsatirazi ndi chitetezo chomwe chimadalira momwe mungagwiritsire ntchito.
C = Zofunikira zolemetsa za casters
L = Kuchuluka kwa ngolo yamagalimoto
W = Kulemera kwa ngolo
n = chiwerengero cha oponya omwe amagwiritsidwa ntchito
SF = Chitetezo
Mayendedwe am'nyumba = 1.35 (osakwana 3 mph)
Kuyendera panja pamanja = 1.8 (osakwana 3 mph)
Zoyendera zoyendetsedwa ndi mphamvu zamkati = 2 (zochepera 3 mph)
Zoyendera zoyendetsedwa ndi mphamvu zakunja = 3 (zochepera 3 mph)
Zotsatirazi ndi mtundu wosavuta wa equation iyi pangolo yokhazikika ya 4-caster yokhala ndi 2 zapadziko lonse lapansi ndi 2 zowongolera, zokhala ndi zolemetsa pa gudumu lililonse pansi pamayendedwe apanyumba:
C = Mphamvu yolemetsa yofunikira pa ma casters
L = Kuchuluka kwa trolley
W = Kulemera kwa ngolo
Mwachitsanzo, taganizirani ngolo ya 300 lb yokhala ndi katundu wa 1,800 lb. Izi zitha kukhala 2,100 lbs. kugawidwa ndi 3. Pa katundu uyu, caster aliyense ayenera kuthandizira / kuyesedwa kwa 700 lbs. kapena zambiri.
Zinthu zina ziyenera kuwunikiridwa kuti zifotokozereni momwe ma caster amafunikira pakugwiritsa ntchito, monga: kasinthidwe ka caster, kutentha kozungulira, kuzungulira kwa ntchito, zinthu zopondaponda, ndi liwiro (mawilo okhala ndi ma mayendedwe a mpira adzakhala ndi mphamvu yocheperako pa liwiro la 3 mph).
Monga nthawi zonse, akatswiri athu oyankha amatha kukambirana za ntchito yanu kuti muwonetsetse kuti caster yolondola ikugwiritsidwa ntchito, popeza ma caster ndi opitilira mawilo.
Chachitatu, ndi kutentha kotani kwa malo omwe amagwiritsidwa ntchito? Kodi ma caster amagwiritsidwa ntchito m'nyumba kapena kunja? Pogwiritsidwa ntchito kwenikweni, kutentha kwakukulu ndi kutsika kudzakhudza ntchito ya caster pamlingo wina.
Chachinayi, ndi mikhalidwe yotani komanso malo omwe oponya anu azigwiritsidwa ntchito? Kodi pali zinyalala? Kodi pali chinyezi kapena mankhwala owopsa? Kodi dzuŵa likuwomba mosalekeza kwa oponya? Kodi magetsi osasunthika apita kwa oponya ndikuwononga zinthu zamtengo wapatali?
Mafunso onsewa ndi enanso ayenera kulowa munjira yopangira zisankho.
Ngati muli ndi mafunso ambiri okhudza kusankha caster, omasuka kutilankhulani mwachinsinsi.
