Ezweni lemishini esindayo, ukubaluleka kwezingxenye ezithembekile nezihlala isikhathi eside akunakugcizelelwa. Phakathi kwalezi,amathrekhi okukhasa enjoloba, eyaziwa nangokuthi amathrekhi okumba irabha, idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kwemishini eyahlukahlukene yokwakha neyokulima. Njengoba izimboni ziqhubeka nokuthuthuka, isidingo semizila yokukhasa irabha esezingeni eliphezulu siye sanda, okwenza kwadingeka izinqubo zokulayisha nezokuthumela ezisebenza kahle ukuze kuhlangatshezwane nezidingo zemakethe.

Imizila yokumba irabha yenzelwe ukunikeza ukubamba okuphezulu nokuzinza ezindaweni ezahlukene, okwenza ibe yindawo ekahle kakhulu yokumba, ama-bulldozer, kanye neminye imishini esindayo. Ukwakheka kwayo kwerabha akugcini nje ngokunciphisa umonakalo womhlabathi kodwa futhi kunciphisa umsindo nokudlidliza, okwenza kube ukukhetha okuthandwayo kumaphrojekthi okwakha amadolobha. Kodwa-ke, izinzuzo zale mizila zedlula ukusebenza kwazo; ukuthuthwa kwemizila yokukhasa irabha yokulayisha nokuthumela kubaluleke ngokulinganayo ukuqinisekisa ukuthi ifika lapho iya khona isesimweni esihle.

Uma kukhulunywa ngokulayishaamathrekhi okumba irabha, ukunemba kubalulekile. Amasu okuphatha afanele kumele asetshenziswe ukuvimbela noma yimuphi umonakalo ngesikhathi senqubo yokulayisha. Lokhu kuhlanganisa ukusebenzisa imishini ekhethekile ukuphakamisa nokubeka imizila ngokuphephile ezimotweni zokuthutha. Ngaphezu kwalokho, ukuqinisekisa ukuthi imizila ivikelekile ngokwanele ngesikhathi sokuhamba kubalulekile ukuvimbela ukuguquka, okungaholela ekugugeni nasekudabukeni.

Imizila yokukhasa yerabha yokuthumela idinga ukuhlela ngokucophelela kanye nokusebenza. Izinkampani kumele zicabangele izici ezifana nesisindo, ubukhulu, kanye nendawo eziya kuyo ukuze zikhethe indlela yokuthumela esebenza kahle kakhulu. Kungakhathaliseki ukuthi ngomhlaba, olwandle, noma emoyeni, umgomo ukuletha lezi zinto ezibalulekile ngokushesha nangokuphephile ezindaweni zokwakha noma kubathengisi bemishini.

Ekuphetheni, ukulayishwa nokuthunyelwa kwemizila yokukhasa yerabha kuyizingxenye ezibalulekile zochungechunge lokuhlinzeka embonini yemishini esindayo. Ngokubeka phambili ukusebenza kahle nokunakekela kulezi zinqubo, amabhizinisi angaqinisekisa ukuthiamathrekhi okumba irabhabafika sebelungele ukusebenza, ekugcineni befaka isandla empumelelweni yemiklamo yokwakha neyezolimo emhlabeni wonke.
