Izixhumi zezimoto ziyizingxenye zokuvikela ezivamile uma kuqhathaniswa ezisetshenziswa ekukhiqizeni kwanamuhla, futhi zibalulekile ekuthuthukiseni ukuzinza kokuxhunywa kwedivayisi.Izixhumi zisetshenziswa kakhulu ekukhiqizeni nasekuphileni kwethu, futhi akudingekile ukusho emkhakheni wokusetshenziswa kwemikhiqizo kagesi.Imikhiqizo kagesi engenazo izixhumi iyimihlobiso engenamsebenzi.Nakuba ziwumzimba oyinhloko, izixhumi ziyizesekeli kuphela, kodwa Ukubaluleka kokubili kuyafana, ikakhulukazi ngesikhathi sokuqaphela ukudluliswa kolwazi lwemishini ye-electromechanical, ebonisa indima ebalulekile yesixhumi.
