I-Crane Wire Rock Drum iyingxenye esemqoka yendlela yokuphakamisa, esetshenziselwa ikakhulukazi ukudluliswa okuhlelekile okuhlelekile kanye nokuthathwa kwamandla kwentambo yocingo ukuze uqaphele ukuphakanyiswa nokwehliswa kwezinto ezisindayo. Njengengxenye esemqoka yohlelo oluthwala umthwalo, ukusebenza kwalo kuthinta ngqo umthamo womthwalo, ukuqina kokuqina nokuphepha kwe-crane. Ngokwezimo ezihlukile zohlelo lokusebenza, zingahlukaniswa ngezinhlobo ezimbili: umoya ongqimba olulodwa kanye nokwethayipha okuhlukahlukene, okusetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zebhuloho, i-gantry, umbhoshongo kanye nama-cranes.
Njenge-Hub ebalulekile exhuma uhlelo lweDrayivu nemishini yokukhohlisa, ukusebenza kwesigubhu sentambo ye-crane kunquma ukuqina komthwalo, ukuqina kokuqina kanye nokuphepha kokusebenza kwe-crane. Ngokwezici ezihlelekile, zingahlukaniswa ngezinhlobo ezintathu: umoya ongelona ongqimba, uxhaso oluhlukahlukene kanye nokuxabana.
Ezimweni zokusebenza ezinzima njenge-metallurgy nolwandle, kuyadingeka ukusebenzisa izigubhu ezinezinto ezikhethekile nemiklamo yokuvikela, futhi kunciphise umjikelezo wesondlo ku-50% wemishini ejwayelekile.
