Ma cranes a Marine jibnthawi zambiri amagwiritsidwa ntchito m'mabwalo a zombo ndi madoko osodza kuti asamutse zombo kuchokera kumadzi kupita kumtunda, komanso amagwiritsidwa ntchito m'malo opangira zombo kupanga zombo. M'madzijibcrane imaphatikizapo magawo otsatirawa: khola, cantilever, makina okweza, makina opha, makina owongolera magetsi, ndi mtundu wotseguka wamanja. Ikhoza kusamutsa chombocho kupita ku gombe,galimoto kapena ngolo kuti mupitirize kuyenda.
Malinga ndi zofunika zosiyanasiyana, ngalawajib cranesamatha kunyamula zombo kapena ma yachts olemera osiyanasiyana kuchokera ku gombe, angagwiritsidwe ntchito kukonzanso mabwalo, komanso angagwiritsidwe ntchito kuyika zombo zatsopano m'nyanja. Imagwiritsa ntchito zingwe zofewa kukweza bwato kuti isawonongeke pamtunda.
Pillar slawing jib crane yokwezera ngalawandiwothandiza kwambiri.Amagwiritsidwa ntchito pokweza ma yacht ndipo mizati yake imakhazikika pamphepete mwa mtsinje. Pamwamba pa mzerewu pali mawonekedwe ozungulira, ndipo makina ozungulira amayendetsedwa ndi injini yokhazikika pamwamba pa ndimeyo. Pamwamba pa makina ozungulira amakhala ndi boom. Pali matabwa awiri opingasa pa boom, ndipo pali mbale yotsika ya flange kumapeto kwa mtanda. Chokwera chamagetsi chimayikidwa pamiyala yamtanda kumanzere ndi kumanja kwa boom. Pali nsanja yokonza pamakina ozungulira pamwamba pa ndime, ndi makwerero okwera mbali imodzi ya chipilalacho. Mapangidwewa ali ndi ubwino wa dongosolo loyenera, ntchito yabwino komanso ntchito yokhazikika.
Tisanapange ndikupereka mayankho athu kwa kasitomala aliyense, gulu lathu limafunikira kuwunika kwaukadaulo pamalo omwe kasitomala amagwirira ntchito, malo ochitirako misonkhano ndi malo opanga kuti adziwe zomwe zikuchitika.. Kupereka mwayi wopititsa patsogolo komanso kupititsa patsogolo mafakitale, gulu lathu la uinjiniya nthawi zonse limakhala lodzipereka pantchito zapatsambandintchito zaukadaulo,kupanga njira zoyenera komanso zachuma zokweza makasitomala.
