Iikhreyini ze-gantry ezinyuswe kuloliwe (RMGs) ziikhreyini ezikhethekileyo ezisetyenziswa kwiitheminali zeekhonteyina kunye neeyadi ze-intermodal ukusingatha kunye nokupakisha izitya zokuthumela ngenqanawa. Ziyilelwe ukuba zisebenze kwiintsimbi kunye nokubonelela ngezakhono zokuphatha iikhonteyina ezifanelekileyo. Nazi ezinye zeempawu eziphambili ze-gantry cranes ezixhonywe kuloliwe:
I-Rail-Mounted Design: Ii-RMG zifakwe kwiindlela zikaloliwe okanye ii-gantry rails, ezivumela ukuba zihambe ngendlela emiselweyo kwi-terminal okanye eyadini. Uyilo olunyuswe kuloliwe lunika uzinzo kunye nokuhamba okuchanekileyo kwimisebenzi yokuphatha iikhonteyina.
I-Span kunye nesakhono sokuPhakamisa: Ii-RMG zihlala zinesithuba esikhulu sokugquma imiqolo yesikhongozeli ezininzi kwaye zinokuphatha uluhlu olubanzi lweesayizi zesikhongozeli. Zifumaneka ngeendlela ezahlukeneyo zokuphakamisa, ukusuka kwishumi ukuya kumakhulu eetoni, kuxhomekeke kwiimfuno ezithile ze-terminal.
Ukupakisha Ukuphakama: Ii-RMGs ziyakwazi ukupakisha izitya ngokuthe nkqo ukunyusa ukusetyenziswa kwendawo ekhoyo kwi-terminal. Bayakwazi ukuphakamisa izikhongozeli ukuya kumphakamo obalulekileyo, ngokwesiqhelo ukuya kuthi ga kwizikhongozeli ezintlanu ukuya kwezintandathu ukuphakama, ngokuxhomekeke kubume bekhreyini kunye nomthamo wokuphakamisa.
I-Trolley kunye ne-Spreader: Ii-RMG zixhotyiswe ngenkqubo yetroli ehamba ecaleni kwe-beam engundoqo ye-crane. I-trolley ithwala i-spreader, esetyenziselwa ukuphakamisa kunye nokunciphisa izitya. I-spreader sinokuhlengahlengiswa ukuze silingane ubungakanani besikhongozeli ezahlukeneyo kunye neentlobo.
Izitishi zoMgqomo: Ii-RMG zisetyenziswa kakhulu kwiitheminali zeekhonteyina zokuphatha kunye nokupakisha izitya zokuthumela ngenqanawa. Badlala indima ebalulekileyo ekulayisheni nasekothuleni izikhongozelo ezinqanaweni, kwakunye nokudlulisa izikhongozeli phakathi kweendawo ezahlukeneyo zetheminali, ezinje ngeeyadi zokugcina, iindawo zokulayisha iilori, kunye neendawo ezisecaleni zikaloliwe.
Iiyadi ze-Intermodal: Ii-RMGs ziqeshwe kwiiyadi ze-intermodal yadi apho ii-container zikhutshelwa phakathi kweendlela ezahlukeneyo zothutho, ezifana neenqanawa, iilori kunye noololiwe. Bavumela ukuphathwa kakuhle kunye nokucwangciswa kwesikhongozelo, ukuqinisekisa ukuhanjiswa okugudileyo kunye nokwandisa ukuhamba kwempahla.
Izikhululo zoThutho lukaloliwe: Iikhreyini ze-gantry ezixhonywe kuloliwe zisetyenziswa kwiitheminali zokuthutha iimpahla zikaloliwe ukuze zilawule iikhonteyina kunye neminye imithwalo enzima yokulayisha nokuthulula uloliwe. Baququzelela ukuhanjiswa ngokufanelekileyo kwempahla phakathi koololiwe kunye neelori okanye iindawo zokugcina.
Amaziko oShishino: Ii-RMG zifumana izicelo kumaziko ahlukeneyo emizi-mveliso apho imithwalo enzima ifuna ukushenxiswa kwaye ipakishwe. Zisetyenziswa kwizityalo zokuvelisa, iindawo zokugcina, kunye namaziko okuhambisa izinto zokuphatha, amacandelo, kunye neemveliso ezigqityiweyo.
Ukwandiswa kweZibuko kunye noPhuculo: Xa kwandiswa okanye kuphuculwa amazibuko asele ekhona, iikhreyini ze-gantry ezixhonywe kumzila kaloliwe zihlala zifakelwa ukwandisa umthamo wokuphatha isikhongozeli kunye nokuphucula ukusebenza kakuhle. Bavumela ukusetyenziswa ngokufanelekileyo kwendawo ekhoyo kwaye baphucule imveliso iyonke yezibuko.
Uyilo kunye nobuNjineli: Inkqubo iqala ngesigaba soyilo kunye nobunjineli, apho iimfuno ezithile ze-gantry crane zichongiwe. Oku kubandakanya izinto ezinje ngokuphakamisa umthamo, ubude bexesha, ubude bokupakisha, izinto ezizenzekelayo, kunye nokuqwalaselwa kokhuseleko. Iinjineli zisebenzisa isoftware yoyilo oluncediswa yikhompyuter (CAD) ukuphuhlisa iimodeli ezineenkcukacha ze-3D zecrane, kubandakanya nesakhiwo esiphambili, inkqubo yetroli, isisasazo, iinkqubo zombane, kunye neendlela zokulawula.
Ukulungiswa kwezinto kunye nokuFakwa: Emva kokuba uyilo lugqityiwe, inkqubo yokuvelisa iqala ngokulungiswa kwezinto. Amacandelo aphezulu ensimbi kunye namacwecwe athengwa ngokweenkcukacha. Izinto zentsimbi ziyasikwa, zibunjwe, ze zenziwe zibe ngamacandelo ahlukeneyo, njengemiqadi, iintsika, imilenze, kunye nezibindi, kusetyenziswa iinkqubo ezifana nokusika, ukuwelda kunye nomatshini. Ukuqulunqwa kwenziwa ngokuhambelana nemigangatho yoshishino kunye nemilinganiselo yokulawula umgangatho.
INdibano: Kwinqanaba lendibano, amacandelo aqulunqiweyo ahlanganiswe ukuze enze isakhiwo esiphambili se-gantry crane. Oku kubandakanya umqadi ophambili, imilenze, kunye nezakhiwo ezixhasayo. Inkqubo yetroli, ebandakanya umatshini wokunyusa, isakhelo setroli, kunye ne-spreader, ihlanganiswe kwaye idibaniswe nesakhiwo esiphambili. Iinkqubo zombane, ezifana neentambo zombane, iipaneli zokulawula, ii-motor, i-sensors, kunye nezixhobo zokukhusela, zifakwe kwaye zixhunywe ukuqinisekisa ukusebenza kakuhle kunye nokulawulwa kwe-crane.
