Ivili elikhokelayo lenzelwe ukusetyenziswa kwii-caterpillar excavators kunye noomatshini abakhethekileyo abanobunzima obuziitoni ezi-3 ukuya kwezingama-50. Le nkqubo ibandakanya uluhlu lweengcali, kubandakanya ukubumba, ukuwelda kunye nokuvelisa. Itekhnoloji yonyango lobushushu ephucukileyo iphucula ukuqina, kunye namandla okumelana nemithwalo enzima ngelixa inciphisa umngcipheko wokwaphuka.
