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 i-gantry crane ehamba ngerabha ethayiwe, ngokuvamile enikwa 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 ohlukahlukene wamaphiko ukusuka 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 (ama-RTG) amabili ahlinzeka isitaki.

Inhloso ye-gantry crane egxunyekwe ngaphezulu kwesitsha 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 ezizenzakalelayo buthuthuke ngokushesha, okugxilwe kukho amakhreni alawula ukugcinwa okumaphakathi kweziqukathi ngaphakathi kwegceke.
