Ama-Cranes-to-ogwini aqukethe ama-cranes, abizwa nangokuthi ama-cranes ama-quay noma amabhuloho e-crane, aqashiwe ukulayisha okukhethekile nokulayisha imishini ekhethekile ezindaweni ezisetshenziswayo zezitsha futhi ngokuvamile atholakala kwi-quayside of terminals ethekwini. Umsebenzi wabo oyinhloko ukulayisha nokulayisha umthwalo wezimpahla ezivela emikhunjini yezitsha ezifakwe ezifakwe ezifakwe, uqinisekise ukunyakaza okuphephile nokusebenzayo kwemithwalo engenayo nangaphandle kwetheku.
Okuhlukile kuma-cranes ama-quay, ama-cranes egcekile, eyaziwa nangokuthi ama-stanes e-gantry e-amporer, aklanyelwe ukulayisha ngokulayisha nokulayisha egcekeni lesitsha. Uhlobo oluvame kakhulu lwegceke lwe-gantry Crane (RMG), umshini okhethekile osetshenziswe emayadini athile. Ama-RMGs asebenzisa amasondo okugijima ngojantshi ukuze aphakamise kanye neziqukathi zezitaki futhi afakwe ama-spreads abuyiselwe ama-20- kanye namamitha aphansi ukuze akwazi ukuhlalisa iziqukathi zosayizi ahlukahlukene.
Uma kuqhathaniswa nama-ruble gantry cranes (RTGS), ama-RMG anikela ngezinzuzo eziningana. Okokuqala, basebenzisa ugesi kagesi njengomthombo wamandla, ukuqeda ukungcoliswa kwamafutha nokuba nobungane ngokwemvelo. Okwesibili, bangakhulisa ukuphakamisa amandla kanye nesivinini, ukwenza ngcono ukulayisha nokulayisha ukusebenza kahle. Ngaphezu kwalokho, i-Trolley ye-RMG iyakwazi ukuhamba ngokushesha ngenkathi iphakamisa imithwalo, iqhubekela phambili ngejubane elisebenzayo kanye nokuvumelana nezimo.
Ngamafuphi, ama-cranes ama-quay kanye nama-cranes egcekeni adlala indima ebalulekile ezipheqululini naseyadini. Abagcini nje ngokuthuthuka kokulayisha nokuthumela ukusebenza kahle kepha futhi baqinisekisa ukuphepha kanye nomnotho wokusebenza.
