Izinhlobo Zamakhreni Asetshenziswa Emachwebeni Ukuthuthwa kwempahla ngobuningi, noma izinto zomthamo owedlula iziqukathi, kudinga amakhreni akhethekile, anezinamathiselo kanye nendlela yokusebenzisa ifoni njengemodemu ukuze zinyakaze ngaphakathi kwendawo yokugcina izimpahla, ichweba, noma indawo yokusebenza. I-port gantry crane iyingqalasizinda eyisisekelo yokuphatha izimpahla nemikhumbi kuzo zonke izinhlobo zamachweba iwukhreyini osuselwe edokhuni wezimpahla kanye nokuthulula. Iqhaza lama-cranes, ikakhulukazi ama-cranes asindayo afana nama-port gantry cranes, aziswa kakhulu ezikhumulweni njengoba inani elikhulu lempahla lidinga ukuqoqwa, ukuhanjiswa, nokukhishwa esitsheni kuya kwesinye, okwenza okhreni abasindayo babaluleke kakhulu ekusebenzeni.
I-port gantry crane isetshenziswa kakhulu ukulayisha kanye nokuthulula iziqukathi ezivela emikhunjini, kanye nokuphatha impahla kanye neziqukathi zokupakisha kumatheminali. Ngokuthuthukiswa kwemikhumbi yeziqukathi, le gantry crane edokhini idinga ukusebenza kahle okuphezulu nekhono eliphezulu lokuphatha imikhumbi emikhulu yamabhokisi. I-port gantry crane ingase futhi isebenze njengedokhi yomkhumbi-to-shore gantry crane ukuze kulayishwe futhi kuthulwe iziqukathi ze-intermodal ezikebheni. I-container crane (futhi i-gantry crane ebamba isiqukathi noma i-ship-to-shore crane) iwuhlobo lwe-gantry crane enkulu kuma-pier etholakala kumatheminali esiqukathi ukuze kulayishwe futhi kuthululwe iziqukathi ze-intermodal ezisuka emikhunjini yeziqukathi.
Umsebenzi omkhulu womqhubi we-crane ethekwini ukulayisha kanye nokuthulula iziqukathi ukuze zithunyelwe zisuka emkhunjini noma emkhunjini. I-crane iphinde ithathe iziqukathi emakhrethini esikhumulweni semikhumbi ukuze zilayishe emkhunjini. Ngaphandle kosizo lwe-Port Cranes, iziqukathi azikwazi ukupakishwa esitokisini, noma zilayishwe emkhunjini.
Ngokusekelwe ekuzibophezeleni kwethu komkhiqizo, sihlinzeka ngesixazululo esiqondiswe kuwo wonke umjikelezo. Ukukusiza ukuthi ufinyelele umsebenzi wokuphakamisa ukonga, osebenzayo futhi ophumelelayo. Okwamanje, amakhasimende ethu asabalale emazweni angaphezu kuka-100. Sizoqhubeka nokuqhubekela phambili ngenhloso yethu yasekuqaleni.
