umkhumbi wokukhombisa amadoboni
Ukumbiwa kwemayini ngama-bulldozer kuyindlela eyisisekelo ekusebenzeni kwemayini engaphezulu, ehlanganisa amandla, ukusebenza kahle, nokusebenziseka kalula ekusetshenzisweni kokuhamba komhlaba. Le mishini eqinile yakhelwe ngokukhethekile ukusebenza ezimayini ezinkulu, inezakhiwo eziqinisiwe, izinjini ezinamandla, nezinto ezikhethekile ezenzelwe imisebenzi ehlukahlukene yezimayini. Umsebenzi oyinhloko wama-bulldozer ezimayini ukuqeda umthwalo osindayo, ukudala imigwaqo yokufinyelela, ukugcina imigwaqo yokuthutha isesimweni esihle nokusiza ekusebenzeni kwezinto ezibonakalayo. Le mishini ifakwe izinhlelo eziphambili ze-hydraulic, ukulawula ama-blade okuqondiswa i-GPS, namakamelo omshayeli we-ergonomic ukuze kusetshenziswe izinto ezihamba kahle futhi kukhiqizwe kahle. Ama-bulldozer anamuhla asebenza ngezinto zobuchwepheshe obuyinkimbinkimbi, kuhlanganise nezinhlelo zokuqapha isikhathi sangempela, ukulawula izinga lokushisa okuzenzakalelayo, nezinjini ezonga uphethiloli ezihambisana nemithetho engokwemvelo. Izicelo zazo zisakazeka ezindaweni ezihlukahlukene zezimayini, kusukela ekukhishweni kwamalahle namaminerali kuya ekulungiseleleni indawo yokwakha nasemiklamweni yokuvuselela umhlaba. Le mishini inezinhlelo ezenziwe ngcono zokuphakamisa imishini ezenzelwe ukuba ihlale isikhathi eside ezimweni ezinzima ezimayini, ezinye izinhlobo zikwazi ukusebenza emithambekeni efinyelela kuma-degree angu-45. Ngaphezu kwalokho, zinemishini yokuphepha esezingeni eliphakeme, kuhlanganise nezinhlelo zokuvikela ukuguqulwa, izindlela zokuvala eziphuthumayo, kanye nezinkomba eziphelele zokuqapha ezinikeza opharetha imininingwane ebalulekile yokusebenza.
