Iswishi ifakwa kukhebhu, futhi iphinikhodi yokuphepha ingafakwa ngokumane ucindezele inkinobho yokushintsha kukhebhu.Ngakho-ke, inkathazo yokuphuma ku-cab igcinwa.Ubuchwepheshe obusha bokuvula nokuvala iphinikhodi yokuphepha kutholakala ngokusetshenziswa kwesistimu yokushayela kagesi ye-excavator, kunesistimu ye-hydraulic.Ngakho-ke, ukucindezela kwamafutha abiza kakhulu kushintshwa ugesi, okusindisa izindleko ekukhiqizeni.Ku-cab, umsindo we-automatic wophondo ungasetshenziswa ukuthola ukuthi ixhunyiwe yini.Endabeni yocingo oluphukile, ukuphepha kokuguqulwa kwezandla kungaqinisekiswa.
