Umxube wekhonkrithi weplanethi ukhiqiza izitini zekhonkrithi Izici Eziyinhloko
1) Ukusebenza kahle kokuxubana kanye nokulingana okuphezulu
2) Kulula ukufaka nokunakekela, Akukho nkinga yokuvuza.
3) Ukusebenza ngokuzenzakalelayo okuphezulu kanye nokuhlakanipha
4) Umxube wekhonkrithi weplanethi ohlonyiswe ngomshini wokuhlola izinga lokushisa nomswakama (ukulinganisa izinga lokushisa nomswakama ngesikhathi sangempela)
5) Ukunemba okuphezulu kokulinganisa
6) Ukudla okunobungani nemvelo kanye ne-hopper yokuphakamisa ehlanganisiwe yokulwa nokuwa
①Umxube wekhonkrithi weplanethi ②Isitshalo sokuhlanganisa ③Uhlelo lokulawula oluzenzakalelayo ④I-Silo ⑤ Isikulufu sokuhambisa
Okwedlule: Umxube wekhonkrithi we-spiral shaft ophindwe kabili Olandelayo: Umxube wekhonkrithi weplanethi
