Inxalenye enkulu yobomi benkonzo yetyathanga ngenxa yonyango lobushushu, ke, inkampani iyaqhubeka yazisa ngezixhobo zonyango olushushu kwaye iphuhlise inkqubo yonyango entsha; owona mthwalo wokugqibela wekhonkco ikakhulu uxhomekeke kwinkqubo yonyango lobushushu lwetyathanga; ixesha lokuqina elide kunye nokunxiba ukuxhathisa (ubomi benkonzo) yetyathanga ikakhulu kuxhomekeke kwinkqubo yonyango lobushushu lomkhono kunye ne-pin shaft; ngokwethiyori yomgqomo, umgangatho wentambo yonke egqityiweyo ixhomekeke kwinxalenye kunye nomgangatho osezantsi ke ngoko, sililawula ngokungqongqo inani leenxalenye, ukucima okanye ukucima kunye nexesha lokufaka umoya ukuqinisekisa ukufana komgangatho wenxalenye nganye, ukuze Ukuqina komphezulu kunye nokuqina kwangaphakathi kwenxalenye nganye kunokufikelela kwixabiso elifanelekileyo, ukuze kufezekiswe uzinzo lomgangatho wekhonkco lemveliso egqityiweyo.
