Chifukwa kamangidwe ka crane ndizovuta komanso zazikulu, zichulukitsa kuchitika kwa ngozi ya crane pamlingo wina, zomwe zitha kuwopseza chitetezo cha ogwira ntchito.Chifukwa chake, kuwonetsetsa kuti makina onyamulira akugwira ntchito moyenera kwakhala chinthu chofunikira kwambiri pakuwongolera zida zapadera zamakono.Nkhaniyi isanthula zoopsa zobisika zachitetezo momwemo kuti aliyense apewe zoopsa munthawi yake.
Choyamba, zoopsa zobisika zotetezedwa ndi zolakwika zilipo mu makina onyamulira okha.Chifukwa chakuti mayunitsi ambiri ogwira ntchito yomanga sapereka chidwi chokwanira pakugwira ntchito kwa makina onyamulira, izi zapangitsa kusakwanira kwa kukonza ndi kuyang'anira makina onyamulira.Kuphatikiza apo, vuto la kulephera kwa makina onyamula zidachitika.Monga vuto la kutulutsa mafuta pamakina ochepetsera, kugwedezeka kapena phokoso kumachitika pakagwiritsidwa ntchito.M'kupita kwanthawi, zidzabweretsa ngozi zachitetezo.Chinsinsi cha vutoli ndikuti wogwira ntchito yomangayo alibe chidwi chokwanira chokweza makina ndipo sanakhazikitse tebulo lokwezera bwino lamakina.
Chachiwiri, zoopsa zachitetezo ndi zolakwika za zida zamagetsi zamakina onyamula.Zida zamagetsi ndizofunikira kwambiri pazida zamagetsi.Komabe, pakali pano, zivundikiro zambiri zotetezera zapachiyambi zathetsa mavuto panthawi yomanga makina okweza, kotero kuti zida zamagetsi zakhala zikuvutika kwambiri, zomwe zinayambitsa ngozi zambiri zachitetezo.
Chachitatu, kuopsa kwa chitetezo ndi zolakwika za mbali zazikulu za makina onyamula.Zigawo zazikulu za makina okweza amagawidwa m'magulu atatu: imodzi ndi mbedza, ina ndi chingwe cha waya, ndipo potsiriza pulley.Zigawo zitatuzi zimakhudza kwambiri magwiridwe antchito otetezeka komanso okhazikika a makina onyamulira.Ntchito yaikulu ya mbedza ndi kupachika zinthu zolemera.Chifukwa chake, munthawi yayitali yogwiritsidwa ntchito, mbedzayo imakhala yovuta kwambiri pakupuma kutopa.Ndipo mbedza ikangokhala pamapewa ndi zinthu zambiri zolemetsa, padzakhala vuto lalikulu la ngozi yachitetezo.Chingwe chawaya ndi gawo lina la makina onyamulira omwe amanyamula zinthu zolemera.Ndipo chifukwa cha kugwiritsiridwa ntchito kwa nthawi yaitali ndi kuvala, ziyenera kukhala ndi vuto lopunduka, ndipo ngozi zimachitika mosavuta pankhani ya kulemera kwakukulu.N'chimodzimodzinso ndi ma pulleys.Chifukwa cha kutsetsereka kwa nthawi yayitali, pulley imachitika mosavutikira m'ming'alu ndi kuwonongeka.Ngati zowonongeka zimachitika panthawi yomanga, ngozi zazikulu zachitetezo zidzachitika mosapeŵeka.
Chachinayi, mavuto omwe alipo pakugwiritsa ntchito makina onyamulira.Wogwiritsa ntchito makina onyamulira sadziwa zambiri zokhudzana ndi chitetezo cha crane.Kugwiritsa ntchito molakwika makina onyamulira kudzawononga kwambiri makina onyamulira komanso ogwiritsa ntchito okha.
