Mfundo yogwirira ntchito ya elevator ndikugwiritsa ntchito mayendedwe a conveyor sprocket ndi unyolo kuyendetsa hopper mmwamba ndi pansi molunjika kapena diagonally, potero kukweza zida molunjika kapena diagonally. Mfundo yaikulu ya elevator ndi motere:
1. Pambuyo poyendetsa galimotoyo, sprocket ya conveyor imayamba kuzungulira, kuyendetsa hopper motsatira njira yokhazikika kudzera mu unyolo.
2. Chingwecho chikakwera mmwamba motsatira chikepe, uku kumatchedwa kukweza. Chophimbacho chimadzaza ndi zinthu, ndipo zinthuzo zimakwera mmwamba motsatira chikepe.
3. Chophimbacho chikasunthira pansi motsatira chikepe, uku kumatchedwa kutaya. Zinthuzo zimatsitsidwa ndikugwera m'malo osonkhanitsira zinthu kuti zinyamulidwe.
4. Njira zotsatizana ndi kukweza ndi kutaya zimachitika mosalekeza, ndipo zinthuzo zimanyamulidwa ndikutulutsidwa mozungulira.
