Kwimiba yokuphathwa kwezinto kunye nokuhanjiswa kweekhonteyina, ukusetyenziswa kweekhreyini ezikhethekileyo kubalulekile ekusebenzeni kakuhle nangokukhuselekileyo. Kule meko, iintlobo ezimbini zeekhreyini ezisetyenziswa rhoqo zeziI-Gantry Crane ekhweliswe kwiSitimela (RMG)kwayeI-Rabber Tyre Gantry Crane (RTG)Nangona zombini zisetyenziselwa ukuphakamisa nokuhambisa izikhongozeli, kukho umahluko omkhulu phakathi kwezi zimbini ozenza zilungele ukusetyenziswa okuthile.
Ikreni yeRMG:
I-RMG crane, ekwaziwa ngokuba yi-rail-mounted double-girder gantry crane, luhlobo lwe-crane olusetyenziswa kakhulu kwimisebenzi ephakathi kwe-modal efana nee-container terminals kunye nee-rail yards. Njengoko igama lisitsho, ii-RMG crane zifakelwa kwii-rails, nto leyo evumela ukuba zihambe ngeendlela ezizinzileyo ukuze ziphathwe kakuhle kwii-container. Olu phawu lwenza ukuba zilungele imisebenzi efuna ukuba izi-container zibekwe ngendlela echanekileyo nehlelekileyo.
Enye yezona nzuzo ziphambili zeekhreyini zeRMG kukukwazi ukusingatha imithwalo enzima ngokuchanekileyo. Uyilo lwe-double-girder lubonelela ngozinzo oluphuculweyo kunye nomthamo wokuphakamisa, okwenza ikhreyini yeRMG ifaneleke ukuphakamisa izikhongozeli eziqhelekileyo nezinzima. Ukongeza, ulungiselelo olufakwe kwithrekhi luvumela intshukumo engenamthungo ecaleni kwethrekhi, kunciphisa umngcipheko weengozi kwaye kwandisa ukusebenza kakuhle ngokubanzi.
Ikreni ye-RTG:
Kwelinye icala, i-RTG crane, eyaziwa ngokuba yi-tire-type mobile container crane okanye i-tire-type port gantry crane, luhlobo lwe-crane olusetyenziswa kakhulu kwiindawo zokubeka iinqanawa nakwiindawo zokubeka iinqanawa. Ngokungafaniyo nee-RMG crane, ii-RTG crane zixhotyiswe ngamatayara erabha, nto leyo evumela ukuba zihambe kwaye zisebenze ngendlela eguquguqukayo ngaphakathi kwindawo yokubeka iinqanawa. Oku kuhamba kwenza ii-RTG crane zifikelele kwiikhonteyina kwiindawo ezahlukeneyo zokugcina izinto, nto leyo ebonelela ngokuguquguquka kwimisebenzi yokuphatha iikhonteyina.
Iingenelo eziphambili zeekhreyini ze-RTG kukuba ziyakwazi ukuhamba kakuhle kwaye ziguquguquka. Njengoko zikwazi ukuhamba ngamatayara erabha, iikhreyini ze-RTG zinokuhamba kwiiyadi zesiphelo, zithathe kwaye zibeke izikhongozeli njengoko kufuneka. Olu phawu luluncedo ngakumbi kwiikhreyini ezinezicwangciso zokugcina eziguquguqukayo, apho izikhongozeli zihlala zifuduswa kwaye zibekwe ngokutsha ngokusekelwe kwiimfuno zokusebenza.
Umahluko phakathi kweekhreyini ze-RMG kunye ne-RTG:
Nangona zombini iikhreyini ze-RMG kunye ne-RTG zenzelwe ukuphatha iikhonteyina, kukho umahluko obalulekileyo phakathi kwezi ntlobo zimbini zeekhreyini. Umahluko ophawulekayo uquka:
1. Ukushukuma: Iikhreyini ze-RMG ziqiniswe kwiireyile kwaye zihamba ngendlela emiselweyo, ngelixa iikhreyini ze-RTG zihambahamba kwaye zinokuhamba ngokukhululekileyo kwindawo yokugcina izinto.
2. Indawo yokusebenza: Iikhreyini ze-RMG zihlala zisetyenziswa kwiindawo zothutho eziphakathi kunye neeyadi zikaloliwe, ngelixa iikhreyini ze-RTG zihlala zisetyenziswa kwiindawo zokubeka iinqanawa kunye neeyadi zeekhonteyina.
3. Umthamo wokuphatha: Iikhreyini ze-RMG zilungele ukuphatha imithwalo enzima kunye nokubeka izikhongozeli ngokuchanekileyo, ngelixa iikhreyini ze-RTG zibonelela ngokuguquguquka kokufikelela kwizikhongozeli kwiindawo zokugcina izinto eziguquguqukayo.
4. Iimfuno zeZiseko zoPhuhliso: Iikhreyini ze-RMG zifuna iziseko zophuhliso zikaloliwe ezizinikeleyo ukuze zisebenze, ngelixa iikhreyini ze-RTG zisebenza kwiindawo ezigangathiweyo ngaphakathi kwendawo yedokhi.
Ngamafutshane, nangona zombini iikhreyini ze-RMG kunye ne-RTG zisetyenziselwa ukuphatha izikhongozeli, uyilo lwazo kunye neempawu zokusebenza kwazo zenza zifaneleke kwiindawo ezahlukeneyo kunye nokusetyenziswa. Ukuqonda umahluko phakathi kweekhreyini ze-RMG kunye ne-RTG kubalulekile ekukhetheni izixhobo ezifanelekileyo ngokusekelwe kwiimfuno ezithile zesiphelo sesikhongozeli okanye isibonelelo se-intermodal. Ngokusebenzisa izibonelelo ezizodwa zohlobo ngalunye lwekhreyini, abaqhubi banokuphucula imisebenzi yokuphatha izikhongozeli kwaye bonyuse ukusebenza kakuhle kwekhonkco lezothutho.
