Ukutyala imali kwi-120A ephezulu yangoku kuthetha utyalo-mali ekusebenzeni kakuhle kunye nemveliso. Ukulinganiswa kwayo kwangoku okuphezulu kunciphisa ilahleko yamandla kunye nokuphucula ukusebenza ngokubanzi kwezixhobo ezixhunyiwe, okubangelwa ukunyuka kwemveliso kunye neendleko zokusebenza eziphantsi. Ukongeza, uyilo lwayo olulula ukuyifaka kunye nolondolozo-simahla longa ixesha kunye nomzamo, kukuvumela ukuba ugxile kwimisebenzi yeshishini engundoqo. Isishwankathelo, i-120A ephezulu-yangoku i-receptacle ene-hexagonal interface kunye nokudityaniswa kwe-stud ngumdlalo wokutshintsha kwezicelo eziphezulu zangoku. Iimpawu zayo ezigqwesileyo, kubandakanywa umthamo ophezulu wangoku, ukuguquguquka, ukulinganisa ukhuseleko kunye nokusebenza kakuhle, kwenza kube yinto efanelekileyo kuluhlu olubanzi lwamashishini. Phucula uqhagamshelo lwakho lwamandla namhlanje ngale ndawo intsha kwaye ufumane umahluko onokuthi uwenze ekusebenzeni kwakho.
