1. Zvinoenderana nemamiriro ekushandiswa
a.Pakusarudza vhiri rakakodzera, chinhu chekutanga chaunofanira kufunga nezvacho huremu hwevhiri rinokweva mavhiri. Semuenzaniso, muzvitoro zvikuru, muzvikoro, muzvipatara, muzvivakwa zvemahofisi nemahotera, pasi pakanaka, pakanaka uye zvinhu zvinotakurwa zvinowanzova zvakapfava, zvichireva kuti vhiri rega rega rinorema kubva pa10 kusvika 140kg. Saka, sarudzo yakakodzera vhiri rinokweva mavhiri rakaumbwa uchishandisa nzira yekugadzika paplate yesimbi yakatetepa (2-4mm). Rudzi urwu rwevhiri rinokweva, rinochinjika, uye risinganyanyi kurira.
b.Munzvimbo dzakadai semafekitori nematura uko kutakurwa kwezvinhu kunowanzoitwa kakawanda uye mutoro wacho wakanyanya kurema (280-420kg), tinokurudzira kushandisa vhiri rekutakura zvinhu rakagadzirwa nesimbi ine ukobvu hwe5-6mm.
c.Kana ikashandiswa kutakura zvinhu zvinorema zvakaita sezvinowanikwa mumafekitori emachira, mafekitori emotokari, kana mafekitori emuchina, nekuda kwemutoro wakakura uye daro refu rekufamba, caster yega yega inofanira kukwanisa kutakura 350-1200kg, uye inogadzirwa uchishandisa simbi ine 8-12mm gobvu. Carrier yemavhiri inofambiswa inoshandisa plane ball bearing, uye bhora bearing inoiswa paplate yepasi, zvichibvumira caster kutakura mutoro unorema uku ichiri kuchengetedza kutenderera kunochinjika uye kuramba kukanganiswa. Tinokurudzira kushandisa mavhiri ecaster akagadzirwa nenylon yakasimbiswa (PA6) super polyurethane kana rabha. Zvichienderana nezvinodiwa zvekushandisa, inogona zvakare kugayiwa kana kupfapfaidzwa nekurapwa kwekudzivirira ngura, pamwe nekugadzirwa kwekudzivirira kutenderera.
d.Nzvimbo dzakakosha: nzvimbo dzinotonhora uye dzinopisa zvakanyanya dzinoisa dambudziko guru pamidziyo yemagetsi, uye kana tembiricha yanyanya, tinokurudzira zvinhu zvinotevera
· tembiricha dzakaderera dziri pasi pe -45℃: polyurethane
· tembiricha dzakakwirira dziri pedyo kana kupfuura 230℃: macaster anotenderera anodzivirira kupisa
2. Maererano nekukwanisa kwekutakura
Panguva yekusarudza simba rekutakura remacaster, vashandisi vanofanirwa kufunga nezvemiganhu chaiyo yekuchengetedza. Isu tinoshandisa macaster ane mavhiri mana anonyanya kushandiswa semuenzaniso, kunyange hazvo sarudzo dzichifanira kuitwa zvichibva pane nzira mbiri dzinotevera:
a.Matangi matatu ane huremu hwese: Rimwe rematangi rinofanira kusungirirwa. Nzira iyi yakakodzera kushandiswa apo matangi ane simba guru mumamiriro ekunze asina kunaka paanenge achifambisa zvinhu kana michina, kunyanya muhuwandu hukuru, hunorema hwese.
b.Matangi mana ane huremu hwe120%: Nzira iyi yakakodzera mamiriro evhu akanaka, uye simba rematangi harinyanyi kukosha panguva yekufambisa zvinhu kana michina.
c.Verenga huwandu hwekutakura: kuti uverenge huwandu hwekutakura hunodiwa nevaya vanokanda zvinhu, zvakakosha kuziva huremu hwemidziyo yekutakura, huwandu hwepamusoro hwemutoro uye huwandu hwemavhiri ekugadzira zvinhu zvinoshandiswa. Huremu hwemutoro hunodiwa pavhiri rekugadzira zvinhu kana kuti vhiri rekugadzira zvinhu hunoverengerwa seizvi:
T= (E+Z)/M×N
---T= huremu hwemutoro hunodiwa pavhiri remuchina wekugadzira kana muchina wekugadzira
---E = uremu hwemidziyo yekuendesa
---Z= mutoro wepamusoro
---M= nhamba yemavhiri ecaster nemacaster anoshandiswa
---N= Chinhu chekuchengetedza (anenge 1.3 - 1.5).
Kuchenjerera kunofanira kupiwa kune zviitiko apo macaster achasangana nehuwandu hwakawanda hwekurovera. Haisi caster chete ine mutoro mukuru wekutakura zvinhu inofanira kusarudzwa, asiwo zvivakwa zvekudzivirira kurovera zvakagadzirwa nehunyanzvi zvinofanira kusarudzwa. Kana zvichidikanwa bhureki, macaster ane mabhureki rimwe chete kana maviri anofanira kusarudzwa.
