Xa kufikwa ekuphakamiseni izinto ezinzima kwindawo yemizi-mveliso,iikhreyini ze-gantrykwayeiikhreyini zejibZimbini iindlela ezidumileyo zokukhetha. Zombini ezi ntlobo zeekhreyini zibalulekile ekuhambiseni izinto ngokufanelekileyo kwimizi-mveliso, kwiindawo zokugcina impahla nakwiindawo zokwakha. Ukuqonda umahluko phakathi kweekhreyini ze-gantry kunye neekhreyini ze-jib kunokunceda amashishini ukuba enze izigqibo ezinolwazi malunga nokuba loluphi uhlobo lwekhreyini olufanele iimfuno zawo.
Iikhreyini zeGantryzizixhobo zokuphakamisa ezinemisebenzi emininzi ezisetyenziswa kakhulu kwiindawo zoshishino. Ezi cranes zixhotyiswe ngemiqadi ethe tye exhaswa yimilenze emibini, evumela ukuba zihambe ngendlela yomzila okanye inkqubo yomzila. Iicranes ze-gantry zilungele ukuphakamisa nokuthutha izinto ezinzima kwiindawo ezinkulu, nto leyo ezenza zilungele ukusetyenziswa njengokulayisha nokukhupha iimpahla kwiindawo zokugcina impahla kunye nokuhambisa izinto kwiindawo zokwenza imveliso.
Ai-jib craneyi-crane yemizi-mveliso ene-jib okanye i-boom ethe tye efakwe kwi-mast okanye eludongeni oluthe nkqo. Ezi crane zenzelwe ukubonelela ngobuchule obuphezulu bokuhamba kunye nokuchaneka, okwenza zifaneleke kwimisebenzi efuna ukuphakamisa nokubeka imithwalo kwiindawo ezithile. Ii-crane ze-Jib zisetyenziswa rhoqo kwiindawo zokusebenzela, imigca yokuhlanganisa kunye neendawo zokulungisa ukuphakamisa oomatshini abanzima kunye nezixhobo ngokulula.
Umahluko ophambili phakathi kwee-gantry cranes kunye nee-jib cranes luyilo kunye nokusebenza kwazo. Ii-gantry cranes zaziwa ngokukwazi kwazo ukugubungela iindawo ezinkulu zokusebenza kunye nokusingatha imithwalo enzima, ngelixa ii-jib cranes zixatyiswa ngokuguquguquka kwazo kunye nokukwazi ukufikelela kwiindawo ezincinci okanye ezithintelweyo. Zombini ezi ntlobo zee-cranes zibonelela ngeenzuzo ezikhethekileyo, kwaye ukhetho phakathi kwazo ekugqibeleni luxhomekeke kwiimfuno ezithile zesicelo.
