I-gantry crane yesondo lerabha uhlobo lwe-crane olusetshenziswa emayadini eziqukathi nezimbobo ngenjongo yokuphakamisa, ukuhambisa, kanye nokupakisha iziqukathi. Ukhrane ohambayo onamasondo axhunywe esisekelweni sawo, okuvumela ukuthi uhambe egcekeni noma echwebeni kalula. Ama-cranes e-Rubber tire gantry aziwa ngokuhlukahluka kwawo, isivinini, kanye nokusebenza kahle kwezindleko uma kuqhathaniswa nezinye izinhlobo zama-cranes.
Ezinye zezici ezibalulekile kanye nezinzuzo ze-raber tire gantry cranes zihlanganisa:
1. Ukusebenza kahle okuphezulu kanye nesivinini sokusebenza. Lawa ma-cranes ayakwazi ukuphatha iziqukathi ngokushesha nangempumelelo, okusiza ekwehliseni isikhathi sokushintshwa kwechweba noma igceke lesitsha.
2. Ukuhamba: Ama-cranes e-Rubber tire gantry angahanjiswa kalula egcekeni lesiqukathi noma echwebeni, okuwenza alungele ukuphatha iziqukathi ezindaweni ezahlukene.
3. Ukuphepha: Lawa ma-cranes afakwe izici zokuphepha ukuze kuqinisekiswe ukuthi izingozi ziyancishiswa ngesikhathi sokusebenza.
4. Ayinandaba nemvelo: Njengoba esebenza ngamathayi enjoloba, la ma-cranes akhiqiza umsindo omncane nokungcola uma kuqhathaniswa nezinye izinhlobo zama-cranes.
Ama-cranes e-Rubber Tire Gantry (RTG) asetshenziswa kakhulu kumayadi weziqukathi namachweba okuphatha kanye neziqukathi ezihambayo. Lawa ma-cranes abalulekile ekusebenzeni kahle nangempumelelo kulezi zikhungo. Ezinye zezinkambu zokufaka isicelo ze-Rubber Tire Gantry cranes yilezi:
1. Ukusebenza kwegceke lesiqukathi: Okhreyini be-RTG basetshenziselwa ukupakisha iziqukathi zokuthumela nokuyihambisa egcekeni lesitsha. Bangakwazi ukuphatha iziqukathi eziningi ngesikhathi esisodwa, okusheshisa imisebenzi yokuphatha iziqukathi.
2. Ukuthuthwa kwezimpahla ezishintshashintshayo: Okhreyini be-RTG basetshenziswa ezindaweni zokuthutha ezihlukene, njengamayadi kaloliwe namadepho amaloli, ukuze kulayishwe futhi kuthululwe iziqukathi ezitimeleni namaloli.
3. Imisebenzi yokugcinwa kwempahla: Okhreyini be-RTG bangasetshenziswa emisebenzini yokugcina izimpahla zokuthutha kanye neziqukathi.
Sekukonke, ama-cranes e-Rubber Tire Gantry adlala indima ebalulekile embonini yezokuthutha, evumela ukuphathwa kahle kweziqukathi nezokuthutha.
Inqubo yokukhiqiza i-gantry crane yamasondo erabha egcekeni leziqukathi kanye nechweba ibandakanya izigaba ezimbalwa. Okokuqala, ukwakheka kanye nokucaciswa kwe-crane kuyaqedwa. Uhlaka lube selwakhiwe kusetshenziswa imishayo yensimbi, efakwa emathayini enjoloba amane ukuze kube lula ukuhamba egcekeni noma echwebeni.
Okulandelayo, kufakwa izinhlelo ze-elekthronikhi kanye ne-hydraulic, kufaka phakathi ama-motor nama-control panel. I-boom ye-crane ibe isihlanganiswa kusetshenziswa amashubhu ensimbi futhi i-hoist ne-trolley ixhunywe kuwo. Ikhebhu ye-crane nayo ifakiwe, kanye nezilawuli ze-opharetha nezinhlelo zokuphepha.
Ngemva kokuqedwa, i-crane ihlolwa ngokuqinile ukuze kuqinisekiswe ukuthi ihlangabezana nekhwalithi nezindinganiso zokuphepha. Uma isiphumelele zonke izivivinyo, i-crane iyahlakazwa futhi ihanjiswe endaweni yayo yokugcina.
Esizeni, i-crane ihlanganiswa kabusha, futhi ukulungiswa kokugcina kwenziwa ukuze kuqinisekiswe ukuthi isebenza kahle. Khona-ke u-crane usulungele ukusetshenziswa emayadini eziqukathi nasemachwebeni ukuthutha impahla phakathi kwamaloli, izitimela, nemikhumbi.
