Chifukwa kapangidwe ka crane kumakhala kovuta komanso kwakukulu, kumawonjezera ngozi ya crane pamlingo wina, womwe udzawopsezedwa kwambiri ndi ogwira ntchito. Chifukwa chake, onetsetsani kuti makina oyenera kukweza tsopano ndi chinthu chofunikira kwambiri cha chithandizo chapadera cha zida zapadera. Nkhaniyi ifotokoza zoopsa zobisika kwa aliyense kuti apewe kuopsa munthawi yake.
Choyamba, ngozi zobisika zobisika ndi zolakwika zomwe zilipo mu makina owoneka okha. Chifukwa maofesi omanga omangawo samalamizidwa kwambiri pakugwira ntchito kwa makina onyamula, izi zapangitsa kusowa pokonza ndi kuwongolera kwa makina onyamula. Kuphatikiza apo, vuto la kulephera kwa makina okweza lidachitika. Monga vuto la kutaya kwamafuta mu makina ochepetsera, kugwedezeka kapena phokoso limachitika mukamagwiritsa ntchito. Pakapita nthawi, zimabweretsa ngozi za chitetezo. Chinsinsi cha vutoli ndikuti wogwira ntchito yomanga ilibe chidwi chokwanira kukweza makina ndipo sanakhazikitse tebulo lokonzedwa bwino.
Chachiwiri, ngozi zachitetezo ndi chilema cha zida zamagetsi zonyamula makina. Zida zamagetsi ndi gawo lofunikira la zida zamagetsi. Komabe, pakadali pano, chitetezo chambiri choyambirira chasandutsa mavuto pakupanga makina kukweza, kotero kuti magetsi amagetsi avala zoopsa, zomwe zimayambitsa ngozi zingapo.
Chachitatu, ngozi zachitetezo ndi zolakwika za zigawo zazikulu za makina okweza. Magawo akuluakulu a makina okweza amagawidwa m'mitundu itatu: imodzi ndi mbedza, inayo ndi chingwe chomangira, ndipo pamapeto pake pulley. Zinthu zitatu izi zimakhala ndi zofunika pakugwira ntchito yotetezeka komanso yolimba. Udindo waukulu wa mbedza ndikupachika zinthu zolemera. Chifukwa chake, nthawi yayitali yogwiritsa ntchito, mbedza imakonda kwambiri kutopa. Ndipo kamodzi mbewa ili pamapewa okhala ndi zinthu zambiri zolemera, padzakhala vuto lalikulu langozi. Chingwe cha waya ndi gawo lina la makina okweza zomwe zimakweza zinthu zolemera. Ndipo chifukwa cha kugwiritsa ntchito ndi kuvala kwakanthawi, kumayenera kukhala ndi vuto loletsa, ndipo ngozi zimachitika mosavuta pankhani yodzaza katundu wonenepa kwambiri. Zomwezi ndi zomwe zimachitika ndi ma pulleys. Chifukwa cha nthawi yayitali - kukwera kumachitika mu ming'alu ndi kuwonongeka. Ngati zofooka zimachitika panthawi yomanga, Ngozi yayikulu chitetezo idzachitika.
Chachinayi, mavuto omwe alipo pakugwiritsa ntchito makina onyamula. Wogwiritsa ntchito makina okweza samadziwika bwino ndi chitetezo cha chitetezo chokhudzana ndi crane. Kugwiritsa ntchito molakwika makina kukweza kumayambitsa kuwonongeka kwakukulu kwa makina omwe akuwonetsa ndi ochita opaleshoni okha.
