Iyo yekudziya yedhiramu bhitumini inonyunguduka mudziyo ndeye kupisa, kunyunguduka uye bhitumini kunyungudika kuburikidza nendiro yekudziya. Iyo inonyanya kuumbwa nedhiramu yekubvisa bhokisi, yekusimudza sisitimu, propeller uye yemagetsi control system.

Bhokisi rebhitumini rinonyunguduka ngoma rakakamurwa kuita makamuri ekumusoro neepasi. Imba yepamusoro ikamuri inonyunguduka yebhitumini, iyo yakafukidzwa zvakanyanya nemafuta ekudziya macoil kana pombi dzekudziya kwemhepo. Btumen rinopisa uye rinonyunguduka uye rinobuda mudhiramu. Iyo crane hook inoiswa pane gantry, uye bhaketi rekubata rinoturikwa. Bhakiti rebhitumini rinosimudzwa newinji yemagetsi, yobva yafambiswa nedivi kuti iise bhaketi rebhitumini panjanji. Ipapo propeller inosaidzira bhaketi muimba yepamusoro kuburikidza nenjanji mbiri dzegwara, uye panguva imwe chete, bhaketi risina chinhu rinobudiswa kubva kumashure kwekubuda. Pane anti-drip mafuta tank pamusuwo webhitumini. Iyo bhitumini inopinda mukamuri yepasi yebhokisi uye inoramba ichipisa kusvikira kutonhora kunosvika anenge 100, iyo inogona kutakurwa. Zvadaro inopombwa mutangi rebhitumini nepombi yebhitumini. Imba yepasi inogona zvakare kushandiswa sebhitumini yekudziya tangi.
Midziyo yekunyungudusa Drum ine hunhu hwekusadzivirirwa nenharaunda yekuvakira, kuchinjika kwakasimba, uye kuderera kwakanyanya kwekutadza. Kana kugadzirwa kukuru kuchidikanwa, mayunitsi akawanda anogona kuunganidzwa.
