Umzimba wemoto ngokubanzi uneentsika ezintathu, ikholamu yangaphambili (ikholamu A), ikholamu ephakathi (ikholamu B), ikholam yangasemva (ikholamu C) ukusuka ngaphambili ukuya ngasemva. Kwiimoto, ngaphezu kwenkxaso, ikholomu nayo idlala indima yesakhelo somnyango.
Ikholamu yangaphambili yikholomu yokudibanisa ekhohlo nasekunene edibanisa uphahla kwi-cabin yangaphambili. Ikholamu yangaphambili iphakathi kwekhompatimenti ye-injini kunye ne-cockpit, ngaphezulu kwezibuko zasekhohlo nezasekunene, kwaye iya kuvala indawo ye-horizon yakho ejikayo, ngakumbi xa ujika ngasekhohlo, ngoko kuxoxwe ngakumbi.
I-Angle apho ikholamu yangaphambili ibhloka imbono yomqhubi kufuneka kwakhona ithathelwe ingqalelo xa kuqwalaselwa ikholomu yangaphambili yejometri. Kwiimeko eziqhelekileyo, umgca wokujonga umqhubi ngekholamu yangaphambili, i-binocular overlap Angle yetotali yi-5-6 degrees, ukusuka kwinduduzo yomqhubi, i-Angle encinci i-overlap, ingcono, kodwa oku kubandakanya ukuqina kwekholamu yangaphambili. , kungekhona nje ukuba nobukhulu obuthile bejometri ukugcina ubunzima obuphezulu bekholamu yangaphambili, kodwa nokunciphisa umgca womqhubi wempembelelo yokubona i-occlusion, yingxaki ephikisanayo. Umyili kufuneka azame ukulinganisa ezi zimbini ukuze afumane iziphumo ezilungileyo. KuMboniso weemoto waMazwe ngaMazwe waseMntla Melika ngo-2001, iVolvo yaseSweden yazisa iSCC yayo yamva nje yemoto. Ikholomu yangaphambili yatshintshwa ibe yifom ecacileyo, efakwe ngeglasi ecacileyo ukwenzela ukuba umqhubi abone ihlabathi langaphandle ngekholomu, ukwenzela ukuba indawo eyimfama yentsimi yombono iyancipha ibe yincinci.
