I-Rubber Tire Gantry Crane/RTG (i-crane), noma ngezinye izikhathi i-transtainer, iyi-crane ehambayo, enamasondo, esebenza phansi noma enqwabelanisa iziqukathi ze-intermodal. Ngenxa yokuhamba kwe-gantry crane enerabha enamathayela erabha, i-gantry crane ingathuthelwa ezindaweni ezikude futhi isetshenziselwe ukulayisha noma ukulayisha iziqukathi ze-intermodal ezikebheni. Ngokungafani nama-gantry cranes abekwe ujantshi anezingoma ezingaguquki, i-gantry crane ethayiwe yerabha iwuhlobo lwe-gantry crane ehambayo esebenzisa i-chassis yenjoloba ukuhamba, okwenza ukubamba izinto kube lula, kusebenze kahle, futhi kuvikeleke.
Kungaba i-gantry crane yesitsha esifakwe amathayi erabha esetshenziswa esikhumulweni semikhumbi yakho, ilifti yesikebhe ehambayo esetshenziswa emsebenzini wakho wokuphakamisa umkhumbi noma i-gantry crane ethwala kanzima yamaphrojekthi akho wokwakha. Ama-gantry cranes afakwe amathayi enjoloba azinzile, asebenza kahle, futhi agcinwa kalula, anemiyalelo eyanele yokuphepha kanye namadivayisi okuvikela ukugcwala ngokweqile aqinisekisa ukuphepha kwabaqhubi nezinto zokusebenza ngokusemandleni azo. Ama-cranes ahlukahlukene e-RTG ayakwazi ukusebenza ezindaweni ezibanzi ngokuguquguquka, anezici ezifana nezinga eliphezulu lokusetshenziswa kwendawo, ukusebenza okuphezulu, namayadi ezimoto agcwele.
Ama-cranes e-RTG angakhuphula izinga lokusetshenziswa kwendawo yokugcina impahla, amboze indawo enkulu yokuphakamisa, indawo ehambayo. Hhayi nje ukuhamba endaweni yokulayisha, ama-cranes e-RTG angafinyelela ekuphathweni okuguquguqukayo kwemishini. Okhreni be-RTG bafanele ukuhlanganisa iziqukathi ezinhlanu-eziyisishagalombili kanye nokuphakamisa ubude ukusuka kwezingu-3 ukuya kwezingu-1 kuya kwezingu-6. Ngokukhula okusheshayo ekuthuthweni kweziqukathi zomhlaba wonke, imijikelezo emifushane yokulethwa, okhreyini be-Rubber-tyred gantry cranes (RTG cranes) kanye nama-gantry cranes agibela umzila (RMG cranes) asetshenziswa kakhulu emayadini eziqukathi, okhreni bekhwalithi ephezulu be-RTG kanye nokhreyini be-RMG bafunwa okwengeziwe. ngabasebenzisi.
Ngenxa yokuhamba kwe-gantry crane enamathayi erabha, i-gantry crane ethayiwe yerabha ingathuthelwa ezindaweni ezikude futhi isetshenziselwe ukulayisha noma ukulayisha iziqukathi ezisuka emikhunjini enezinto eziningi. Ama-cranes e-RTG ashintshashintshashintshashintshayo ayakwazi ukusebenza ezindaweni ezikude, anamazinga aphezulu okusetshenziswa, ukusebenza okuphezulu, namayadi agcwele ezinjini. Ukhreyini we-RTG usetshenziswa eziphaleni phakathi kweziqukathi ezinhlanu kuya kweziyisishiyagalombili ububanzi, kanye nokuphakamisa ukuphakama phakathi kweziqukathi ezingaphezu kuka-3 kuya kweziyisi-6 ubude. Ngomklamo onjalo weselula, lolu hlobo lwe-gantry crane lungasetshenziswa emayadini amaningi okuqukatha eduze komunye nomunye, ngaphandle kokutshala imali emishinini evamile ye-Gantry yegceke ngalinye.
Ama-Smart RTGs, anezakhiwo zensimbi ezihlakaniphile namadokodo omqhubi, akwenza kube lula kubaqhubi bakho be-crane ukuthi basebenzise i-crane ngendlela enethezekile, ekhiqizayo. Indlela yokusebenzisa i-crane ngokuyisisekelo yakhiwe imishini yokushayela, isethi yamasondo, ifreyimu ye-crane, kanye nezinsiza zokuphepha.
