Ikhreyini ye-gantry yesikhongozeli, nekwaziwa njengekhreyini yokusuka enqanaweni ukuya elunxwemeni okanye ikhreyini yokuphatha ikhonteyina, yikhreyini enkulu esetyenziselwa ukulayisha, ukothula, kunye nokupakisha izikhongozeli zokuthumela ngenqanawa kumazibuko nakwizikhululo zeecontainer. Iquka amacandelo amaninzi asebenzisanayo ukwenza imisebenzi yawo. Nanga amacandelo aphambili kunye nomgaqo osebenzayo we-gantry crane yesikhongozeli:
Isakhiwo seGantry: Isakhiwo se-gantry yinkqubo ephambili ye-crane, equlethwe yimilenze ethe nkqo kunye ne-horizontal gantry beam. Imilenze iqiniswe ngokuqinileyo phantsi okanye ifakwe kwiireyile, ivumela i-crane ukuba ihambe ecaleni kwe-dock. I-gantry beam idibanisa phakathi kwemilenze kwaye ixhasa inkqubo yetroli.
Inkqubo yetroli: Inkqubo yetroli ihamba ecaleni kwe-gantry beam kwaye iqulethe isakhelo setroli, i-spreader, kunye ne-hoisting mechanism. I-spreader sisixhobo esincamathela kwizikhongozeli kwaye siziphakamise. Inokuba yi-telescopic okanye i-spreader-length-length spreader, kuxhomekeke kuhlobo lwezikhongozeli eziphathwayo.
I-Hosting Mechanism: Indlela yokuphakamisa inoxanduva lokuphakamisa nokuthoba isisasazo kunye nezikhongozeli. Ngokwesiqhelo siquka iintambo zocingo okanye amatyathanga, igubu, kunye nenjini yokunyusela. I-motor ijikeleza igubhu ukuze ivuthe okanye ikhulule iintambo, ngaloo ndlela iphakamisa okanye ihlise i-spreader.
UmGaqo wokuSebenza:
Indawo: I-gantry crane ibekwe kufutshane nenqanawa okanye isitaki sesikhongozeli. Iyakwazi ukuhamba ecaleni kwedokhi kwiireyili okanye amavili ukuze ihambelane nezikhongozeli.
I-Spredier Attachment: I-spreader ithotywa kwisitya kwaye iqhotyoshelwe ngokukhuselekileyo kusetyenziswa iindlela zokutshixa okanye i-twist locks.
Ukuphakamisa: Indlela yokuphakamisa iphakamisa isisasazelo kunye nesikhongozeli ukusuka enqanaweni okanye emhlabeni. I-spreader sinokuba neengalo ze-telescopic ezinokuthi zilungelelanise ububanzi besikhongozeli.
Intshukumo ethe tyaba: I-boom yandisa okanye ihlehla ngokuthe tye, ivumela isisasazo ukuba sihambise isikhongozeli phakathi kwenqanawa kunye nesitaki. Inkqubo yetroli ihamba ecaleni kwe-gantry beam, eyenza ukuba i-spreader ibeke indawo yesikhongozeli ngokuchanekileyo.
Ukupakishwa: Sakuba isikhongozeli sikwindawo oyifunayo, indlela yokusiphakamisa iyasihlisela emhlabeni okanye kwesinye isikhongozeli esikwimfumba. Izikhongozeli zinokupakishwa ngokwemigangatho emininzi phezulu.
Ukothula kunye nokuLayisha: I-container gantry crane iphinda ukunyuswa, ukunyakaza okuthe tye, kunye nenkqubo yokupakisha ukukhulula izikhongozeli ezisuka enqanaweni okanye izikhongozeli zokulayisha enqanaweni.
Ukusebenza kweZibuko: Iikhreyini ze-gantry zesikhongozeli zibalulekile kwimisebenzi yezibuko, apho zijongana nokuhanjiswa kwee-container ukuya nokubuya kwiindlela ezahlukeneyo zothutho, ezinjengeenqanawa, iilori, kunye noololiwe. Baqinisekisa ukubekwa ngokukhawuleza nangokuchanekileyo kwezikhongozeli zokuya phambili.
Izibonelelo ze-Intermodal: Iikhreyini ze-container gantry ziqeshwe kwiindawo ze-intermodal, apho izikhongozeli kufuneka zidluliselwe phakathi kweendlela ezahlukeneyo zothutho. Benza ukuba udluliselo olungenamthungo phakathi kweenqanawa, oololiwe, kunye neelori, ukuqinisekisa ulungiselelo olusebenzayo kunye nokusebenza kwekhonkco lokubonelela.
Iiyadi zeesikhongozelo kunye neendawo zokugcina izitya: Iikhreyini zokugalela iikhonteyina zisetyenziswa kwiiyadi zeekhonteyina nakwiindawo zokugcina ukuze kupakishwe kwaye kuqokelelwe izikhongozeli. Baququzelela ukulungelelaniswa nokugcinwa kwezikhongozeli kwiimfumba ezinemigangatho emininzi ephezulu, ukwandisa ukusetyenziswa kwendawo ekhoyo.
Izikhululo zokuThutha kwiKhonteyina: Iikhreyini ze-container gantry zisetyenziswa kwizikhululo zothutho kwiikhonteyina ukulayishwa kunye nokothula imigqomo kwiilori. Baququzelela ukuhamba kakuhle kwezikhongozelo ukungena nokuphuma kwisikhululo sempahla, kuhlengahlengiswa inkqubo yokuphatha imithwalo.
Inkqubo yokwenziwa kwe-container gantry crane ibandakanya amanqanaba amaninzi, kubandakanywa ukuyila, ukuyila, ukuyihlanganisa, uvavanyo kunye nofakelo. Nantsi isishwankathelo senkqubo yemveliso ye-gantry crane yesikhongozeli:
Uyilo: Inkqubo iqala ngesigaba soyilo, apho iinjineli kunye nabayili baphuhlisa iinkcukacha kunye noyilo lwe-gantry crane. Oku kubandakanya ukumisela umthamo wokuphakamisa, ukufikelela, ukuphakama, ubude, kunye nezinye iimpawu ezifunekayo ngokusekelwe kwiimfuno ezithile ze-port okanye i-container terminal.
Ukuyilwa kwaMalungu: Nje ukuba uyilo lugqityiwe, ukwenziwa kwamacandelo ahlukeneyo kuyaqala. Oku kubandakanya ukusika, ukubumba, kunye nokuwelda intsimbi okanye iipleyiti zetsimbi ukwenza ezona nxalenye zesakhiwo, ezifana nesakhiwo se-gantry, i-boom, imilenze, kunye nemiqadi yokusabalalisa. Amalungu afana nezixhobo zokuxhoma, iitroli, iiphaneli zombane, kunye neenkqubo zokulawula nazo zenziwe ngeli xesha.
Unyango loMphezulu: Emva kokwenziwa, amacandelo angena kwiinkqubo zonyango lomphezulu wokomeleza ukuqina kwawo kunye nokukhuselwa kumhlwa. Oku kunokubandakanya iinkqubo ezifana nokuqhushumba, ukupeyinta, nokupeyinta.
INdibano: Kwinqanaba lendibano, izinto ezenziweyo ziyadityaniswa kwaye zidityaniswe ukuze zenze i-gantry crane. Isakhiwo se-gantry sakhiwe, kwaye i-boom, imilenze, kunye nemiqadi yokusabalalisa ixhunyiwe. Iindlela zokuxhoma, iitroli, iisistim zombane, iipaneli zolawulo, kunye nezixhobo zokhuseleko zifakelwe kwaye ziqhagamshelwe. Inkqubo yokuhlanganisa ingabandakanya i-welding, i-bolting, kunye nokulungelelaniswa kwamacandelo ukuqinisekisa ukufaneleka kunye nokusebenza ngokufanelekileyo.
