Ibikoresho bifata imashini bifata ibyuma bitandukanye, kandi impeta y'imbere ninyuma yinyuma yafashwe.Ubu bwoko bwo gutwara bugabanijwe muburyo butandukanye nkumurongo umwe, umurongo wikubye kabiri hamwe numurongo ine washyizwe kumurongo ukurikije umubare wumurongo washyizweho.
Ubushobozi bwumurongo umwe wapanze uruziga rufite umutwaro wa axial biterwa nu guhuza impande, ni ukuvuga, irushanwa ryo hanze ryiruka.Nini cyane inguni, nubushobozi bwa axial umutwaro.Umurongo umwe wapanze uruziga ni rwo rukoreshwa cyane.Ingano ntoya yimirongo ibiri yapanze ikoreshwa mukibanza cyimbere yimodoka.Imirongo ine yapakishijwe imashini ikoreshwa mumashini aremereye nkurusyo runini rukonje kandi rushyushye.
