Kwimimandla yokuphathwa kwempahla kunye nokuhanjiswa kweekhonteyina, ukusetyenziswa kweekhreyini ezikhethekileyo kubalulekile ekusebenzeni ngokufanelekileyo nangokukhuselekileyo.Kulo mxholo, iindidi ezimbini zecrane ezisetyenziswa ngokuqhelekileyo ziUloliwe oMounted Gantry Crane (RMG)kwayeI-Rubber Tire Gantry Crane (RTG).Ngelixa zombini zisetyenziselwa ukuphakamisa kunye nokuhambisa izikhongozeli, kukho umahluko ocacileyo phakathi kwezi zibini ezizenza zilungele izicelo ezithile.
RMG crane:
Ikhreyini ye-RMG, ekwaziwa ngokuba yi-double-girder gantry crane, luhlobo lwekhreyini edla ngokusetyenziswa kwimisebenzi ye-intermodal efana neetheminali zeekhonteyina kunye neeyadi zikaloliwe.Njengoko igama libonisa, iikhreyini zeRMG zixhonywe koololiwe, zibavumela ukuba bahambe ngeendlela ezimiselweyo zokuphatha isikhongozeli esisebenzayo.Olu phawu luyenza ilungele imisebenzi efuna ukuba izikhongozeli zipakishwe ngendlela echanekileyo nelungelelanisiweyo.
Enye yeenzuzo eziphambili ze-RMG cranes kukukwazi ukuphatha imithwalo enzima ngokuchaneka okuphezulu.Uyilo lwe-double girder lunikeza ukuzinza okuphuculweyo kunye nokuphakamisa amandla, okwenza i-crane ye-RMG ilungele ukuphakamisa umgangatho kunye nezikhongozeli ezinzima.Ukongezelela, ukucwangciswa kwe-track-mounted configuration kuvumela ukuhamba ngokungenamthungo ecaleni kwendlela, ukunciphisa umngcipheko weengozi kunye nokwandisa ukusebenza kakuhle jikelele.
RTG crane:
Kwelinye icala, i-RTG crane, ekwabizwa ngokuba yi-tire-type-container crane okanye i-tire-type-port gantry crane, luhlobo lwecrane oluqhele ukusetyenziswa kwiitheminali zezibuko kunye neeyadi zesikhongozeli.Ngokungafaniyo neekhreyini ze-RMG, iikhreyini ze-RTG zixhotyiswe ngamatayara erabha, ezivumela ukuba ziqhube kwaye zisebenze ngendlela ebhetyebhetye ngakumbi kwindawo yedokhi.Oku kuhamba kwenza ukuba iikhreyini zeRTG zifikelele kwizikhongozeli kwiindawo ezahlukeneyo zokugcina, zibonelela ngezinto ezahlukeneyo kwimisebenzi yokuphatha isikhongozeli.
Iingenelo eziphambili ze-RTG cranes kubuchule bazo kunye nokuguquguquka.Ukwazi ukuhamba ngamatayara erabha, iikhreyini zeRTG zinokuhamba ngeeyadi zetheminali, zikhuphe kwaye zipakishe izikhongozeli njengoko kufuneka.Olu phawu luluncedo ngokukhethekileyo kwiitheminali ezinamalungiselelo okugcina okuguquguqukayo, apho izikhongozeli zihanjiswa rhoqo kwaye zibekwe ngokutsha ngokusekelwe kwiimfuno zokusebenza.
Umahluko phakathi kwe-RMG kunye ne-RTG cranes:
Ngelixa zombini iikhreyini ze-RMG kunye ne-RTG ziyilelwe ukuphatha isikhongozeli, kukho umahluko ophambili phakathi kwezi ntlobo zimbini zeekhreyini.Owona mahluko uphawuleka kakhulu uquka:
1. Ukuhamba: Iikrane ze-RMG zigxininiswe kwii-rails kwaye zihamba ngendlela echazwe kwangaphambili, ngelixa ii-RTG cranes zihamba kwaye zinokuhamba ngokukhululekile kwi-terminal yard.
2. Indawo yokusebenza: Iikhreyini ze-RMG ziqhele ukusetyenziswa kwiindawo zothutho lwe-intermodal kunye neeyadi zikaloliwe, ngelixa iikhreyini zeRTG ziqhele ukusetyenziswa kwiitheminali zezibuko nakwiiyadi zeekhonteyina.
3. Umthamo wokuPhatha: Iikhreyini ze-RMG zilungele ukuphatha imithwalo enzima kunye nokupakisha ngokuchanekileyo izikhongozeli, ngelixa ii-cranes ze-RTG zibonelela ngokuguquguquka kokufikelela kwizikhongozeli kwiindlela zokugcina eziguquguqukayo.
4. IiMfuno zeziseko zophuhliso: Iikhreyini ze-RMG zifuna iziseko zoncedo zikaloliwe ezizinikeleyo ukuze zisebenze, ngelixa iikhreyini zeRTG zisebenza kwindawo egangathiweyo ngaphakathi kwendawo yedokhi.
Isishwankathelo, ngelixa zombini i-RMG kunye ne-RTG cranes zisetyenziselwa ukuphatha i-container, ukuyila kwazo kunye neempawu zokusebenza zibenza bafaneleke kwiindawo ezahlukeneyo kunye nezicelo.Ukuqonda umahluko phakathi kwe-RMG kunye ne-RTG cranes kubalulekile ekukhetheni ezona zixhobo zifanelekileyo ngokusekelwe kwiimfuno ezithile ze-terminal ye-container okanye indawo ye-intermodal.Ngokusebenzisa izibonelelo ezizodwa zohlobo ngalunye lwekhreyini, abaqhubi banokunyusa ukusebenza kokuphatha izikhongozeli kwaye banyuse ukusebenza kakuhle kwekhonkco lolungiselelo.
