I-Harbour Rtg Container Crane Yeziqukathi ezingama-20′ 40′ 45′

Ama-gantry cranes esitsha serabha, ngokuvamile abizwa ngokuthi ama-RTGs ngamafuphi, asetshenziselwa ukupakishwa kweziqukathi emayadini esitsha.Ebizwa nangokuthi isidluliseli sesitsha, ingafushaniswa ngokuthi i-RTG crane, esebenzisa amathayi enjoloba ukuhamba emagcekeni ezimpahla, i-gantry crane ehambayo evame ukusetshenziselwa ukupakisha iziqukathi, amadokhi, nakwezinye izindawo.I-RTG crane iyi-gantry crane ethayiwe eyirabha ephathwayo, evamise ukunikwa amandla uhlelo lokuphehla udizili noma enye insiza yokuphakela ugesi, futhi iyisixazululo esikahle sokuphatha iziqukathi ezinosayizi omaphakathi.
Isitsha se-rtg sinikeza ukusebenza okuhle kakhulu nokuthembeka ezitsheni zokupakisha.Hhayi nje ukuhambahamba endaweni yokulayisha, isiqukathi se-rtg siphinde sivumele ukubekwa kabusha kwemishini nokusebenza ngendlela eguquguqukayo.I-Crane ye-RTG yohlobo lwe-Universal iyisisetshenziswa esibalulekile sembobo yeziqukathi.

Isitsha se-rtg sifanele ukuhlanganisa iziqukathi ezinhlanu-eziyisishiyagalombili kanye nokuphakamisa ukuphakama kusuka kweziqukathi ezi-3 kuye kwezingu-1-ngaphezulu kwezi-6.Okhreni besitsha esine-Rubber-tyreged (RTG) bangahlinzekwa ngosayizi abahlukene bamaphiko kusukela kweziqukathi ezinhlanu kuya kweziyisishiyagalombili ububanzi (kanye nobubanzi bamathrekhi wamaloli), futhi ezinobude bokuphakamisa obusuka ku-1 phezu kwezingu-3 ukuya kwezingu-1 phezu kweziqukathi eziyisi-6.Esithombeni esingenhla, ama-Rubber Tired Overhead Cranes (RTGs) amabili ahlinzeka isitaki.

Inhloso ye-gantry crane egibele phezu kwesiqukathi ukubeka iziqukathi emugqeni wokupakisha.I-Automated Rail-mounted Gantry Cranes (ARMGs) ibilokhu idumile kusukela yasungulwa kumatheminali okwakhiwa okusha, lapho amayunithi okwakha amakhonteyina ancikene nedokodo kuyazuzisa, futhi izindawo zokushintshisana zitholakala ekugcineni kwamayunithi.Idizayini edumile yokushintshisana isebenzisa okhreni ababili be-ARMG abafanayo kubhulokhi yesiqukathi ngasinye, egijima ngethrekhi eyodwa enendawo evamile yokusebenza (bona umfanekiso 1).Ubuchwepheshe bokuphatha iziqukathi obuzenzakalelayo buthuthuke ngokushesha, okugxilwe kukho amakhreni alawula ukugcinwa okumaphakathi kweziqukathi ngaphakathi kwegceke.
