Izimo zokusebenza kwama-excavators, ama-bulldozer, ama-crawler cranes nezinye izinto zokusebenza emishinini yokwakha zinzima, ikakhulukaziabakhasayoohlelweni lokuhamba emsebenzini udinga ukumelana nokushuba okukhulu nomthelela. Ukuze kuhlangatshezwane nezakhiwo zemishini yesiseshi, kuyadingeka ukwenza ukucubungula okushisayo okuhlanganisa nokwelashwa kokushisa, ukufoja, ukusakaza nezinye izinqubo ezingxenyeni eziningi ezakha isiseshi. Izinqubo ezishiwo ngenhla zokucubungula okushisayo yizo zonke izindlela zokucubungula amandla. Ngakho-ke, ukusetshenziswa kwamandla amasha, ubuchwepheshe obusha, nobuchwepheshe obuthuthukisiwe sekuyindlela ebalulekile yokuthuthukisa ngokuqhubekayo ukusebenza komkhiqizo nokunciphisa izindleko zokukhiqiza, kuyilapho kuthuthukiswa ngokuqhubekayo impilo yesevisi yomkhiqizo. Iba yindlela ephumelelayo yokonga amandla.
