Umshini wokwenza amathrekhi kaloliwe ucezu lwezimboni olusetshenziswa ukwenza insimbi ibe amathrekhi amade, aqhubekayo ngenqubo yokugingqika.Umshini usebenza ngokudlulisa umucu wensimbi oqhubekayo kumasethi amaningi amarola abumba kancane kancane insimbi ibe iphrofayili oyifunayo.Imishini yokwakha amaroli wesitimela ivamise ukusetshenziselwa ukwakha amathrekhi kaloliwe, ama- guardrails, nezinye izinhlobo zezakhiwo zensimbi.Lolu lwazi lusekelwe emqondweni wami ojwayelekile.
Yonga isikhathi, imali nomzamo ngemishini yethu yesimanjemanje yokwakha i-orbital roll.Imishini yethu eqinile, ethembekile yakhelwe ukuphatha imisebenzi enzima kalula, ukuze ukwazi ukugxila ekukhuliseni ibhizinisi lakho kanye nokweqa okulindelwe ngamakhasimende.
