I-gantry crane (i-RTG crane) iyisisetshenziswa esisebenza ngezindlela eziningi nesisebenza kahle esisetshenziswa kakhulu emachwebeni, ezikhumulweni zamabhokisi, kumayadi kaloliwe, nasezikhungweni ezinkulu zezokuthutha. Yakhelwe ngokukhethekile ukusebenza kokuphatha iziqukathi, enikeza ukuguquguquka, ukuhamba, nokuthembeka ekupakisheni nasekudluliseleni iziqukathi. Ngokungafani nama-gantry cranes agibeliswe ujantshi, i-gantry crane enerabha edonsa ngamathayi enjoloba ahlala isikhathi eside, eyivumela ukuthi ihambe ngokukhululeka ezindaweni ezihlukene njengokhonkolo, itiyela, noma ngisho nomhlabathi ohlangene ngaphandle kokuvalelwa kumathrekhi angashintshi. Lokhu kuhamba kwenza i-RTG crane ibe yisixazululo esikahle sezinsiza ezidinga ukuphathwa kweziqukathi eziguquguqukayo kuzo zonke izindawo ezibanzi.
Isakhiwo se-gantry crane enamathayi erabha ngokuvamile siwuhlaka lwensimbi olumise u-U olunetroli kanye nendlela yokuphakamisa egijima eduze kwe-gantry beam. Ingakwazi ukuphakamisa iziqukathi ezinosayizi abajwayelekile—20ft, 40ft, noma 45ft—isebenzisa izisakazi ezikhethekile, futhi ibeke kahle imigqa ibe ngu-6 noma engu-7 ukuphakama. I-crane ifakwe izinhlelo zokushayela ezithuthukisiwe, ezivame ukunikwa amandla amajeneretha edizili noma amandla kagesi ngokusebenzisa izixazululo eziyingxube. I-RTG yesimanjeama-craneszivame ukufakwa ama-frequency converters, ubuchwepheshe bokubuyisela amandla, kanye nezinhlelo zokulawula ezihlakaniphile ukuze kuqinisekiswe ukusebenza kahle, ukonga amandla, kanye nokunciphisa ukukhishwa kwekhabhoni, okuhambisana nesidingo sokuthuthukiswa kwechweba eliluhlaza.
Inzuzo eyinhloko yama-gantry cranes anamathayi erabha ilele ekulawuleni okuthuthukisiwe nezici ezizenzakalelayo. Ngobuchwepheshe bokulwa ne-sway, amasistimu wokumisa anembile, kanye nokusebenza kokuzikhethela kokulawula kude, i-RTGama-cranesngcono kakhulu ukuphepha nokusebenza kahle kokuphatha. Amamodeli azenzakalelayo angenza ukupakisha okunganamuntu kanye nokuhlela indlela, ehlise umfutho wabasebenzi kanye nezingozi zokusebenza.
Mayelana nezicelo, i-RTGama-craneszibalulekile kumatheminali amakhonteyina nasemayadini aphakathi nendawo, lapho zisingatha khona ukudluliswa okuvundlile kanye nokupakishwa okuqondile kweziqukathi, okuqinisekisa izikhathi zokushintsha ngokushesha imikhumbi, amaloli, nezitimela. Ukuzivumelanisa nezimo, umthamo oqinile womthwalo, kanye nokusebenza okuhlakaniphile kwenza ama-gantry cranes afakwe amathayi enjoloba abe yisixazululo esingabizi kakhulu nesilungele ikusasa embonini yezokuthutha yesimanje.
♦Ukuguquguquka Okuhle Kakhulu: I-gantry crane enerabha enamathayela erabha ifakwe amasondo enjoloba ahlala isikhathi eside kanye nezinhlelo zokuqondisa ezithuthukisiwe, eziyivumela ukuthi ihambe ngendlela eguquguqukayo ezindleleni eziningi. Ingasebenza kalula emayadini esitsha esiqinile, amachweba, kanye nezindawo zokugcina impahla, iyenze ibe nezinto ezihlukahlukene kakhulu zokupakisha nokudlulisa iziqukathi.
♦Ikhono Lomthwalo Ophakeme: I-gantry crane enerabha ethayiwe iklanyelwe ukuphatha imisebenzi esindayo, enamamodeli amaningi akwazi ukuphakamisa iziqukathi ezinesisindo esingamathani angama-50. Lokhu kuyenza ilungele ukuphathwa kwezimpahla ezinkulu phakathi kwemikhumbi, amaloli, nezindawo zokugcina.
♦ Ukuvikelwa Kwaphansi: Ngenxa yamathayi enjoloba, i-crane isebenza kahle ezindaweni ezihlukene ngaphandle kokudala umonakalo. Lesi sici siqinisekisa ukusebenza okuphephile kuma-flooring akhethekile, amatheminali agandayiwe, namayadi esitsha, kuyilapho kunciphisa izindleko zokulungisa zesikhathi eside.
♦ Izici Zokuphepha Ezithuthukisiwe: Ukuphepha kuyinzuzo enkulu ye-gantry crane enethayi erabha. Ifakwe ama-alamu, izinzwa, nezinsimbi ezidonsa amanzi ukuze kuqinisekiswe ukukhushulwa okuphephile nokunciphisa ubungozi bezingozi. Lezi zindlela zokuphepha zikwenza kuthembeke ekusebenzeni kwechweba elimatasa kanye netheminali.
♦ Ukusebenza kahle Ekusebenzeni: I-gantry crane enethayi erabha ingasebenza ngemodi yezandla noma ezenzakalelayo, inciphisa isikhathi sokuphatha kanye nezidingo zomsebenzi. Iphinde ihambisane nezisabalalisi zeziqukathi nokunye okunamathiselwe okukhethekile, okuthuthukisa ukusebenza kahle ngesikhathi sokulayisha nokuthulula.
♦ Ukusebenza Kwezindleko: Ngokuqeda isidingo semishini yokubamba eyengeziwe, i-gantry crane enethayi lerabha inikeza isisombululo esingabizi kakhulu sokunyakaza nokugcinwa kweziqukathi. Ukuthembeka kwayo kanye nokuguquguquka kwayo kuyenza ibe yinketho ekhethwayo yezinkampani zempahla nemikhumbi emhlabeni jikelele.
I-gantry crane (i-RTG crane) iwumshini oguquguqukayo futhi ohambahambayo osetshenziswa kakhulu emachwebeni, emayadini eziqukathi, kanye namatheminali ekuphatheni impahla ngendlela efanele. Ngokungafani nama-crane agibele kajantshi, i-RTG crane incike kumathayi enjoloba ahlala isikhathi eside esikhundleni samathrekhi angashintshi, iwunikeza ukuguquguquka okukhulu, ukuphumelela kwezindleko, kanye nokuthuthela kalula ezindaweni ezahlukene zokusebenza. Yakhelwe ngohlaka oluqinile lwe-gantry oluhlala i-hoist eyinhloko kanye nendlela yokuphakamisa, ikhreyini ye-RTG yakhelwe ukuphatha iziqukathi ezisindayo namayunithi e-intermodal ngokunemba.
Uma umkhumbi noma iloli lifika esikhumulweni sezindiza, i-RTG crane ingahamba iqonde ngqo endaweni yempahla. Amasondo ayo enjoloba esindayo ayivumela ukuthi ihambe kahle ezindaweni ezihlukene, okuhlanganisa indawo egandaywe yidokhu, amayadi kakhonkolo, ngisho nakumzila wesitimela. Lokhu kuguqulwa okuphezulu kuqinisekisa ukuthi i-crane ye-RTG ingakwazi ukuzivumelanisa ngokushesha nezimo zomsebenzi ezishintshayo, ukunciphisa isikhathi sokuphumula kanye nokwenza ngcono ukusebenza kahle.
Inzuzo ebalulekile yokusebenza kwe-raber tyred gantry crane amandla ayo okuqondisa athuthukile. I-crane ingaphenduka, iqondaniswe nezitaki zesitsha, futhi izule ezindaweni eziqinile ngokuzinza. Ifakwe amasistimu okuqondisa namabhuleki athembekile, i-RTG crane iqinisekisa ukukhushulwa okuphephile nokunyakaza kweziqukathi ngisho nasezikhumulweni ezimatasa.
Inqubo yokuphakamisa inikwa amandla amasistimu kagesi noma amanzi, ashayela i-hoist ukuphakamisa, ukwehlisa, nokuthutha imithwalo esindayo. Enezici ezifana nokuphakamisa okubushelelezi, ukulawulwa kwe-anti-sway, kanye nokuma okunembile, i-crane ye-RTG iqinisekisa ukupakishwa kweziqukathi okusebenzayo nokusebenza kokubuyisa.
Sengiphetha, i-gantry crane ethayiwe yerabha ibalulekile ekuhanjisweni kwesimanjemanje kanye nokuthunyelwa kwemikhumbi. Inhlanganisela yayo yokuhamba, ukuguquguquka, kanye nokusebenza kahle kokuphakamisa kwenza i-RTG crane ibe yimpahla ebalulekile yamachweba namatheminali, iqinisekisa ukuphathwa kwempahla okusheshayo, okuphephile, futhi okungabizi kakhulu kuwo wonke uchungechunge lokuhlinzekwa kwempahla emhlabeni wonke.
