Izimo zokusebenza zemishini yokumba, ama-bulldozer, ama-crawler cranes kanye neminye imishini emishini yokwakha zinzima, ikakhulukaziizikrweqeohlelweni lokuhamba emsebenzini kudingeka limelane nokucindezelwa okukhulu kanye nomthelela. Ukuze kuhlangatshezwane nezakhiwo zemishini ze-crawler, kuyadingeka ukwenza ukucubungula ukushisa okuhlanganisa ukwelashwa kokushisa, ukwakheka, ukusakaza kanye nezinye izinqubo ezingxenyeni eziningi ezakha i-crawler. Izinqubo zokucubungula ukushisa ezishiwo ngenhla zonke ziyizindlela zokucubungula ezisebenzisa amandla amaningi. Ngakho-ke, ukusetshenziswa kwamandla amasha, ubuchwepheshe obusha, kanye nobuchwepheshe obuthuthukisiwe sekuyindlela ebalulekile yokuthuthukisa ukusebenza komkhiqizo njalo nokunciphisa izindleko zokukhiqiza, ngenkathi kuthuthukiswa impilo yesevisi yomkhiqizo njalo. Yiba yindlela ephumelelayo yokonga amandla.
