Kwihlabathi lokuphathwa kwezinto kunye nokuhanjiswa kwezinto, ii-cranes zidlala indima ebalulekileyo ekuthuthweni kwemithwalo ngokukhuselekileyo. Kukho iintlobo ezimbini zee-cranes ezisetyenziswa rhoqo kwiindawo zokungenisa impahla nakwii-terminals zesikhongozeli: ii-cranes ze-gantry ezidinwe ngerabha (ii-RTG) kunye nee-cranes ze-gantry ezifakwe kwi-rail (ii-RMG). Nangona zombini zisebenza ngeenjongo ezifanayo, nganye ineempawu kunye nokusetyenziswa okwahlukileyo.
IiRTGzenzelwe ukuba zisebenze ngamatayara erabha, nto leyo evumela ukuba zihambe ngokukhululekileyo ebaleni. Olu hambo luvumela i-RTG crane ukuba ithuthe izikhongozeli kwiindawo ezahlukeneyo ngaphandle kokuvalelwa kumzila oqinileyo. Oku kulungile ngakumbi kwiindawo apho indawo incinci khona, njengoko inokuthintela imiqobo kwaye inokutshintshwa xa kufuneka. Ii-RTG crane zihlala zisetyenziswa kwiiterminals eziphakathi kunye neeports ezincinci apho ukuguquguquka kunye nokuguquguquka kubalulekile.
Kwelinye icala,I-RMGifakelwe kwiireyile kwaye isebenza ngendlela emiselweyo. Uyilo lubonelela ngokuguquguquka okukhulu nokucaca ekuphatheni izinto. Iikhrayini ze-RMG zihlala zisetyenziselwa izinto ezinkulu ezikwizikhongozeli ezifuna imisebenzi emininzi. Imilo yereyile ivumela ukuba isikhongozeli siphakanyiswe kwaye sihanjiswe kumgama omde, nto leyo eyenza ukuba sibe yindawo efanelekileyo yokugcina izinto kunye neyokugcina impahla.
Omnye umahluko obalulekileyo sisantya namandla. Ii-RMG zihlala zinomthamo omkhulu wokuphakamisa kwaye zinokusebenza ngesantya esiphezulu kunee-RTG. Oku kwenza ii-RMG cranes zilungele imisebenzi emikhulu apho indawo iphezulu.
Ngamafutshane, ii-RTG kunye nee-RMG zombini zibalulekile ekuphatheni izikhongozeli, kodwa umahluko wazo ekusebenzeni, kuyilo, nakwizakhono zokusebenza zenza zilungele iimeko kunye neemfuno ezahlukeneyo. Ukuqonda umahluko kunokunceda abaqhubi bee-crane ezihambayo bakhethe i-crane efanelekileyo kwiimfuno zabo, oko kwandisa imveliso kunye nokusebenza kakuhle kwezixhobo zabo zokuphatha izikhongozeli.
