Pazinthu zogwirira ntchito ndi zotengera zotengera, kugwiritsa ntchito ma cranes apadera ndikofunikira kuti pakhale magwiridwe antchito abwino komanso otetezeka.M'nkhaniyi, mitundu iwiri ya crane yomwe imagwiritsidwa ntchito kwambiri ndiSitima Yokwera Gantry Crane (RMG)ndiCrane ya Rubber Tyre Gantry Crane (RTG).Ngakhale onsewa amagwiritsidwa ntchito kukweza ndi kusuntha zotengera, pali kusiyana kosiyana pakati pa ziwirizi zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zina.
Chingwe cha RMG:
Crane ya RMG, yomwe imadziwikanso kuti njanji yokwera njanji iwiri, ndi mtundu wa crane womwe umagwiritsidwa ntchito kwambiri popanga ma intermodal monga ma terminals ndi mayadi a njanji.Monga momwe dzinalo likusonyezera, ma cranes a RMG amayikidwa pa njanji, kuwalola kuyenda m'njira zosasunthika kuti azigwira bwino zotengera.Izi zimapangitsa kuti zikhale zoyenera kuti ma kontena asungidwe moyenera komanso mwadongosolo.
Ubwino umodzi waukulu wa ma cranes a RMG ndikutha kunyamula katundu wolemera kwambiri mwatsatanetsatane.Mapangidwe awiri-girder amapereka kukhazikika komanso kukweza mphamvu, kupangitsa kuti crane ya RMG ikhale yoyenera kunyamula zotengera zolemetsa komanso zolemetsa.Kuphatikiza apo, kasinthidwe kokhazikitsidwa ndi njanji kumathandizira kusuntha kosasunthika panjira, kuchepetsa chiopsezo cha ngozi ndikuwonjezera magwiridwe antchito.
RTG Crane:
Kumbali inayi, RTG crane, yomwe imadziwikanso kuti tyre-type mobile container crane kapena matayala amtundu wa port gantry crane, ndi mtundu womwe umagwiritsidwa ntchito kwambiri m'madoko ndi mayadi otengera.Mosiyana ndi ma cranes a RMG, ma cranes a RTG amakhala ndi matayala a rabara, kuwalola kuti aziyenda ndikugwira ntchito mosinthika kwambiri mkati mwa doko.Kusuntha kumeneku kumathandizira ma cranes a RTG kuti azitha kupeza zotengera m'malo osiyanasiyana osungira, zomwe zimapangitsa kuti pakhale kusinthasintha kwamachitidwe onyamula chidebe.
Ubwino waukulu wa ma cranes a RTG ndikuwongolera kwawo komanso kusinthasintha.Kutha kuyenda pa matayala a rabara, ma cranes a RTG amatha kuyenda pamayadi omaliza, kubweza ndikusunga zotengera momwe zingafunikire.Izi ndizopindulitsa makamaka pamaterminal omwe ali ndi njira zosungirako zosunthika, pomwe zotengera zimasunthidwa pafupipafupi ndikuziyikanso potengera momwe amagwirira ntchito.
Kusiyana pakati pa ma cranes a RMG ndi RTG:
Ngakhale ma cranes onse a RMG ndi RTG adapangidwa kuti azigwira zotengera, pali kusiyana kwakukulu pakati pa mitundu iwiriyi ya cranes.Zosiyanasiyana zodziwika bwino ndi izi:
1. Kuyenda: Ma cranes a RMG amakhazikika pa njanji ndipo amayenda m'njira yokonzedweratu, pomwe makina a RTG ndi oyenda ndipo amatha kuyenda momasuka pabwalo la terminal.
2. Malo ogwirira ntchito: Makoni a RMG amagwiritsidwa ntchito kwambiri m'malo oyendera ma intermodal ndi mayadi a njanji, pomwe ma RTG amagwiritsiridwa ntchito kwambiri m'madoko ndi mayadi otengera.
3. Kutha Kugwira Ntchito: Ma cranes a RMG ndi abwino kunyamula katundu wolemetsa ndikusunga bwino zotengera, pomwe ma crane a RTG amapereka kusinthasintha kofikira zotengera muzosungirako zosunthika.
4. Zofunikira pa Zomangamanga: Makorani a RMG amafunikira zida za njanji zodzipereka kuti zigwire ntchito, pomwe makina a RTG amagwira ntchito pamalo oyala mkati mwa doko.
Mwachidule, pamene makina onse a RMG ndi RTG amagwiritsidwa ntchito ponyamula ziwiya, mapangidwe awo ndi machitidwe awo amawapangitsa kukhala oyenera madera osiyanasiyana ndi ntchito.Kumvetsetsa kusiyana pakati pa ma cranes a RMG ndi RTG ndikofunikira pakusankha zida zoyenera kwambiri potengera zofunikira za chotengera chotengera kapena malo opangira ma intermodal.Pogwiritsa ntchito maubwino apadera amtundu uliwonse wa crane, ogwiritsira ntchito amatha kukhathamiritsa magwiridwe antchito a chidebe ndikuwonjezera magwiridwe antchito amtundu uliwonse.
