Iyo crane inoderedza ndiyo yakakosha chikamu chechikamu mune yekusimudza michina. Izvo zvinonyanya kushandiswa kuderedza kumhanya kwemotokari uye kuwedzera iyo yekubuda torque, kuitira kuti ityaire kusimudza, kumhanya uye kuuraya michina kuyerera zvakanaka. Hunhu hwayo hwekushanda hwaro hwakakura-hwakakura mutoro wekutakura, zvakakwirira zvekutakura kugona, uye zvinogona kujairana kazhinji kutanga-kumira uye kukanganisa mitoro. Mhando dzakajairika dzevakadzikiswa zvinosanganisira giya inodzvinyirira, honye giya inodzvinyirira uye pasi zvinoderedzwa. Sarudza yakakodzera mhando maererano nezvinodiwa chaizvo zve crane.
Vanoderedza vanowanzoumbwa nehupfumi, magiya, fani uye kusimbisa zvishandiso, uye kuwana kuunganidza uye torque kuwedzera kuburikidza neThelque kuwedzera kweGiredhi neGiredhi Giriy. Iyo yakakwira-yekumhanyisa kutenderera kwemota inotenderedzwa kune iyo kuendesa kuburikidza neyakaisa shaft. Mushure mekunge vaviri vaviri vadzedzisi zvishoma nezvishoma, iyo inodikanwa yakaderera-kumhanya uye yakakwirira-torque simba ndeyekubuda neiyo inobuda shaft. Kuve nechokwadi chekuvimbika, kuderedza kunoda kuve nehurongwa hwakanaka hwekushandisa uye kushandisa zvakakwirira-zvine simba zvinhu kuti zvidzivirire mitoro inorema uye kukanganisa.
Crane anodzikisira anoshandiswa zvakanyanya mumachira, kuvaka, metallurgy uye mamwe minda, uye kuita kwavo zvakanangana nekuchengeteka uye kushanda kwemidziyo. Kugadziriswa Kwezuva Nezuva Kunoda kuongorora nguva dzose kweiyo lubricating chimiro chemafuta, giya kupfeka uye kushaira kuti udzivise kukundikana kana kusapindirana. Yakakwirira-mhando inoderedzwa inogona kuwedzera zvakanyanya hupenyu hwebasa reiyo crane uye kuderedza mari yekuchengetedza.
