Emikhakheni yokuphathwa kwezinto kanye nokuphathwa kweziqukathi, ukusetshenziswa kwama-crane akhethekile kubalulekile ekusebenzeni okuphumelelayo nokuphephile. Kulesi simo, izinhlobo ezimbili zama-crane ezivame ukusetshenziswa yilezi:I-Gantry Crane Egibele Esitimeleni (RMG)futhiI-Gantry Crane Yethayi Lerabha (RTG)Nakuba zombili zisetshenziselwa ukuphakamisa nokuhambisa izitsha, kunemehluko ocacile phakathi kwazo ezenza zifanelekele izinhlelo ezithile.
I-RMG crane:
I-RMG crane, eyaziwa nangokuthi i-double-girder gantry crane efakwe esitimeleni, uhlobo lwe-crane oluvame ukusetshenziswa emisebenzini ye-intermodal efana ne-container terminals kanye ne-rail yards. Njengoba igama lisikisela, ama-RMG crane afakwa ezitimeleni, okuwavumela ukuthi ahambe ngezindlela eziqondile ukuze aphathe kahle izitsha. Lesi sici senza kube kuhle kakhulu emisebenzini edinga ukuthi izitsha zibekwe ngendlela eqondile nehlelekile.
Enye yezinzuzo eziyinhloko zama-RMG cranes yikhono lokusingatha imithwalo esindayo ngokunemba okuphezulu. Umklamo we-double-girder unikeza ukuzinza okuthuthukisiwe kanye nomthamo wokuphakamisa, okwenza i-RMG crane ifanelekele ukuphakamisa izitsha ezijwayelekile nezinzima. Ngaphezu kwalokho, ukucushwa okufakwe kuthrekhi kuvumela ukunyakaza okungenamthungo ethrekhini, kunciphisa ingozi yezingozi futhi kwandise ukusebenza kahle okuphelele.
I-RTG crane:
Ngakolunye uhlangothi, i-RTG crane, eyaziwa nangokuthi i-tray-type mobile container crane noma i-tray-type port gantry crane, iwuhlobo lwe-crane olusetshenziswa kakhulu ezindaweni zokubeka izimbobo kanye nasezindaweni zokubeka izimbobo. Ngokungafani nama-RMG crane, ama-RTG crane afakwe amathayi enjoloba, okuwavumela ukuthi ahambe futhi asebenze ngendlela eguquguqukayo ngaphakathi kwendawo yokubeka izimbobo. Lokhu kuhamba kwenza ama-RTG crane akwazi ukufinyelela ezitsheni ezindaweni ezahlukene zokugcina, okuhlinzeka ngokuguquguquka ekusebenzeni kokuphatha izitsha.
Izinzuzo eziyinhloko zama-RTG cranes ukuthi ayakwazi ukujika kanye nokuguquguquka. Njengoba ekwazi ukuhamba ngamathayi enjoloba, ama-RTG cranes angahamba emagcekeni e-terminal, athathe futhi abeke izitsha njengoba kudingeka. Lesi sici siwusizo kakhulu kuma-terminals anezinhlelo zokugcina eziguquguqukayo, lapho izitsha zivame ukuhanjiswa futhi zibekwe kabusha ngokusekelwe ezidingweni zokusebenza.
Umehluko phakathi kwamakhrayini e-RMG kanye ne-RTG:
Nakuba ama-crane e-RMG kanye ne-RTG enzelwe ukuphathwa kwezitsha, kukhona umehluko omkhulu phakathi kwalezi zinhlobo ezimbili zama-crane. Umehluko ophawuleka kakhulu uhlanganisa:
1. Ukuhamba: Ama-RMG cranes aqiniswe ezitimeleni futhi ahamba ngendlela enqunyiwe, kuyilapho ama-RTG cranes ehambayo futhi angahamba ngokukhululeka egcekeni lesiphelo.
2. Indawo yokusebenza: Ama-RMG cranes avame ukusetshenziswa ezindaweni zokuhamba eziphakathi nendawo kanye nasezindaweni zezitimela, kuyilapho ama-RTG cranes evame ukusetshenziswa ezikhumulweni zemikhumbi kanye nasezindaweni zeziqukathi.
3. Amandla Okuphatha: Ama-RMG cranes alungele ukuphatha imithwalo esindayo kanye nokufaka izitsha ngokunembile, kuyilapho ama-RTG cranes enikeza ukuguquguquka kokufinyelela izitsha ezindaweni zokugcina eziguquguqukayo.
4. Izidingo Zengqalasizinda: Ama-RMG cranes adinga ingqalasizinda yesitimela ezinikele ukuze asebenze, kuyilapho ama-RTG cranes esebenza ezindaweni ezigandayiwe ngaphakathi kwendawo yedokodo.
Ngamafuphi, yize ama-crane e-RMG kanye ne-RTG esetshenziselwa ukuphatha izitsha, ukwakheka kwawo kanye nezici zokusebenza kuwenza afanelekele izindawo ezahlukene kanye nezinhlelo zokusebenza. Ukuqonda umehluko phakathi kwama-crane e-RMG kanye ne-RTG kubalulekile ekukhetheni imishini efaneleke kakhulu ngokusekelwe ezidingweni ezithile zesikhungo se-container noma isikhungo se-intermodal. Ngokusebenzisa izinzuzo ezihlukile zohlobo ngalunye lwe-crane, abaqhubi bangenza ngcono ukusebenza kokuphatha izitsha futhi bandise ukusebenza kahle kweketanga lezokuthutha.
