1. Ho ya ka tikoloho ya tshebediso
a.Ha o kgetha koloi e loketseng ya ho jara mabili, ntho ya pele eo o lokelang ho e nahana ke boima ba koloi e jarang mabili. Mohlala, mabenkeleng a maholo, dikolong, dipetleleng, meahong ya diofisi le dihoteleng, mokatong o motle, o boreleli mme thepa e tsamaiswang hangata e bobebe, ho bolelang hore koloi e nngwe le e nngwe e tla jara boima ba hoo e ka bang 10 ho isa ho 140kg. Ka hona, kgetho e loketseng ke koloi e jarang mabili e entsweng ka ho sebedisa mokhoa wa ho hata poleiting e tshesane ya tshepe (2-4mm). Mofuta ona wa koloi e jarang mabili o bobebe, o tenyetseha, mme o kgutsitse.
b.Libakeng tse kang lifeme le matlo a polokelo moo ho tsamaisoang thepa khafetsa 'me mojaro o le boima haholo (280-420kg), re khothaletsa ho sebelisa sesebelisoa sa ho jara mabili se entsoeng ka poleiti ea tšepe e teteaneng ea 5-6mm.
c.Haeba e sebelisetsoa ho jara lintho tse boima tse kang tse atisang ho fumanoa lifekthering tsa masela, lifekthering tsa likoloi, kapa lifekthering tsa mechini, ka lebaka la mojaro o moholo le sebaka se selelele sa ho tsamaea, caster e 'ngoe le e 'ngoe e lokela ho khona ho jara 350-1200kg, 'me e etsoe ho sebelisoa carrier ea mabili a tšepe a teteaneng a 8-12mm. Carrier ea mabili a tsamaeang e sebelisa bearing ea bolo ea sefofane, 'me bearing ea bolo e kentsoe poleiting e ka tlase, e lumellang caster ho jara mojaro o boima ha e ntse e boloka potoloho e tenyetsehang le khanyetso ea tšusumetso. Re khothaletsa ho sebelisa mabili a caster a entsoeng ka nylon e matlafalitsoeng (PA6) super polyurethane kapa rabara e tsoang kantle ho naha. Ho latela litlhoko tse itseng tsa ts'ebeliso, e ka boela ea galvanized kapa ea fafatsoa ka kalafo ea ho hanyetsa mafome, hammoho le ho fuoa moralo oa thibelo ea ho kobeha.
d.Libaka tse ikhethang: libaka tse batang le tse nang le mocheso o phahameng li beha khatello e kholo holim'a li-caster, 'me maemong a feteletseng a mocheso, re khothaletsa lisebelisoa tse latelang
· mocheso o tlase o ka tlase ho -45℃: polyurethane
· mocheso o phahameng o haufi le kapa o fetang 230℃: li-caster tse ikgethang tse hanelang mocheso
2. Ho ya ka bokgoni ba ho jara
Nakong ea khetho ea bokhoni ba ho jara ba li-caster, basebelisi ba hloka ho ela hloko meeli e itseng ea polokeho. Re sebelisa li-caster tse sebelisoang haholo tsa mabili a mane e le mohlala, leha likhetho li lokela ho etsoa ho latela mekhoa e 'meli e latelang:
a.Li-caster tse 3 tse nang le boima bohle: E 'ngoe ea li-caster e lokela ho emisoa. Mokhoa ona o loketse lits'ebetso moo li-caster li nang le matla a maholo holim'a maemo a mabe a mobu ha li ntse li tsamaisa thepa kapa lisebelisoa, haholo-holo ka bongata bo boholo, bo boima ka kakaretso.
b.Li-caster tse 4 tse nang le boima ba kakaretso ba 120%: Mokhoa ona o loketse maemo a mobu a matle, 'me tšusumetso ho li-caster e nyane haholo nakong ea ho tsamaisoa ha thepa kapa lisebelisoa.
c.Bala bokgoni ba ho jara: e le ho bala bokgoni ba ho jara bo hlokahalang ke di-caster, ho hlokahala ho tseba boima bo feteletseng ba disebediswa tsa ho tsamaisa thepa, mojaro o moholo le palo ya mabili a caster le di-caster tse sebediswang. Bokgoni ba ho jara bo hlokahalang bakeng sa lebili la caster kapa caster bo balwa ka tsela e latelang:
T= (E+Z)/M×N
---T= boima ba mojaro bo hlokahalang bakeng sa lebili la caster kapa caster
---E = boima bo feteletseng ba lisebelisoa tsa ho isa thepa
---Z= mojaro o moholo ka ho fetisisa
---M= palo ea mabili a caster le li-caster tse sebelisitsoeng
---N= Ntlha ea polokeho (hoo e ka bang 1.3 - 1.5).
Ela hloko maemo ao li-caster li tla pepesehela tšusumetso e kholo. Hase feela hore ho lokela ho khethoa caster e nang le bokhoni bo boholo ba ho jara moroalo, empa le meaho e entsoeng ka mokhoa o ikhethileng ea tšireletso ea tšusumetso le eona e lokela ho khethoa. Haeba ho hlokahala brake, li-caster tse nang le li-brake tse le 'ngoe kapa tse peli li lokela ho khethoa.
