Iikhreyini zeGantryziindidi zoomatshini bokuphakamisa abasetyenziselwa imisebenzi yangaphandle kwiiyadi zomthwalo, iistokhwe, ukuphatha imithwalo eninzi, kunye nemisebenzi efanayo. Ulwakhiwo lwabo lwesinyithi lufana nesakhelo esime ngocango, esinokuhamba ngeendlela zomhlaba, kunye nomqadi oyintloko oxhotyiswe ngokukhethekileyo ngee-cantilevers kuzo zombini iziphelo ukwandisa uluhlu lokusebenza. Ngombulelo kwisakhiwo sabo esizinzileyo kunye nokuguquguquka okunamandla, ii-gantry cranes zisetyenziswa ngokubanzi kumazibuko, oololiwe, iifektri kunye neendawo zokwakha.
Iicranes zeGantry zinokuhlelwa ngeendlela ezahlukeneyo:
Ngokwesakhiwo:igila enye okanye i-double girder
Ngobumbeko lwe-cantilever:I-cantilever enye okanye i-cantilever ephindwe kabini
Ngohlobo lwenkxaso:umzila kaloliwe okanye irabha-idiniwe
Ngokuphakamisa isixhobo:hook, i-emele yokubamba, okanye i-electromagnetic
Double main beam hook hook gantry cranesisixhobo sokuphakamisa izinto esinzima, esisetyenziswa ikakhulu ukulayisha kunye nokothula kumazibuko, iiyadi zempahla kunye nezinye iindawo. Ulwakhiwo lwalo luqulathe imiqadi ephambili emibini ehambelanayo, ii-outriggers kunye neegwegwe ukwenza isakhelo se-portal. Idizayini ye-double girder iphakamisa umthamo wokuthwala umthwalo kunye nokuzinza, kwaye ifanelekile kwiindawo ezinkulu zokusebenza, imithwalo enzima yokusebenza. Ihuku inokunyuswa kwaye ithotywe ngokuthe nkqo kwaye ihambise ngokulula izinto ezinzima. I-crane ineempawu zokusebenza okuphezulu, ukhuseleko kunye nokuguquguquka okunamandla, kwaye isetyenziswa kakhulu kwishishini, kwi-logistics kunye nezinye iinkalo.
Indawo eqhelekileyo yokusetyenziswa kwe-double main beam hook hook gantry crane kufuneka ibe phakathi koluhlu lwe -25ºC ~ + 40ºC, kwaye iqondo lobushushu eliphakathi kwiiyure ezingama-24 aliyi kudlula i-35ºC. Akulula ukusebenza kwimidiya evuthayo kunye neziqhushumbisi okanye iindawo ezinomswakama ophezulu kunye neegesi ezitshabalalisayo. Inoluhlu olubanzi lwezicelo kumsebenzi wentsimi, izinto zokubamba, ukusebenza kwefektri kunye nokuthutha.
Xa usebenza kwintsimi, inokusebenza phantsi kweemeko zemihlaba enzima kunye nokuphakama kwayo okunamandla kunye nesakhiwo esizinzile. Umzekelo, kwimigodi emikhulu evulekileyo, inokuphakamisa ngokulula izinto ezinzima ezifana nentsimbi.
Ngokubhekiselele kwizinto zokubamba, nokuba zizinto zetsimbi, iinkuni okanye izinto ezenziwe ngaphambili,iikhreyini zegantryinokubamba ngokuchanekileyo kwaye inokulungelelaniswa kwizixhobo ezahlukeneyo zokuphakamisa ukuhlangabezana neemfuno ezahlukeneyo zokuphakamisa.
Ngaphakathi kumzi-mveliso, sisixhobo esiphambili sokuphatha izinto eziphathekayo. Ukususela ekuphakanyisweni kwezinto eziluhlaza ukuya kwindawo yokucubungula ukuhanjiswa kweemveliso ezigqityiweyo kwindawo yokugcina impahla, i-double main beam hook gantry crane ithatha inxaxheba kuyo yonke inkqubo yokuqinisekisa inkqubo yokuvelisa egudileyo.
Kwikhonkco lezothutho, kumachweba, kwiipaki zezothutho kunye nezinye iindawo, i-gantry cranes inokulayisha ngokukhawuleza kwaye ikhuphe iimpahla kwizithuthi zokuthutha okanye iinqanawa ukukhawulezisa ukuguqulwa kwempahla.
Iimpawu kunye nokuPhakanyiswa kokuSebenza kweentlobo ezahlukeneyo zeGantry Cranes:
♦I-Single Girder Gantry Crane:I-gantry cranes yegirder enyebabe nesakhiwo esilula, ubunzima obulula, kunye nezixhobo eziphantsi kunye neendleko zokuzigcina. Zilungele iisayithi ezincinci kunye nemisebenzi ephantsi kweetoni, njengemizi-mveliso, iindawo zokugcina iimpahla, okanye iidokhi ezincinci, ezinomthamo wokuphakamisa ngokubanzi ukusuka kwiitoni ezi-5 ukuya kwezingama-20. Ngenxa yesakhiwo sabo esikhaphukhaphu, ukufakela kunye nokufuduka kulula, kwaye ukusebenza kuyaguquguquka, okubenza bafaneleke ukuphatha imithwalo elula rhoqo. Nangona kunjalo, umthamo wabo wokuthwala umthwalo ulinganiselwe, okwenza ukuba bangafaneleki kakhulu kwimisebenzi enzima okanye eqhubekayo ye-tonnage ephezulu.
♦I-Double Girder Gantry Crane:I-double girder gantry cranesbonisa isakhiwo esinzima ngakumbi, ubunzima obuphezulu, kunye nezixhobo eziphezulu kunye neendleko zokuzigcina, kodwa zibonelela ngomthamo oqinileyo wokuthwala umthwalo. Zifanelekile kwiindawo ezinkulu kunye nokusebenza kweetoni eziphezulu, ezifana nezixhobo zetsimbi, izityalo zesamente, kunye neeyadi zamalahle, kunye nomthamo wokuphakamisa ngokuqhelekileyo ukusuka kwi-20 ukuya kwiitoni ezingama-500. Isakhiwo se-double girder sinika ukuzinza okukhulu kunye nokukhuseleka, ukuxhasa izixhobo ezinkulu zokuphakamisa kunye nemisebenzi enzima, efanelekileyo yokuphatha umgama omde wezinto ezinzima. Ngenxa yesakhiwo sabo esikhulu, ukufakela kuthatha ixesha elide kwaye iimfuno zesayithi ziphezulu.
♦I-Rail-Mounted Gantry Crane:Iicranes zegantry ezixhonywe kuloliwezixhaswa kwiingoma, zibonelela ngokuzinza okugqwesileyo kohambo kunye nokulungelelanisa. Zisetyenziswa ngokubanzi kwiiyadi zomthwalo wangaphandle, iistokhwe, kunye nokuphathwa kwempahla eninzi kumazibuko, kwimizi-mveliso yombane, okanye kwiitheminali zikaloliwe, ezinamandla okuphakamisa ngokubanzi ukusuka kwiitoni ezi-5 ukuya kwezingama-200. Uyilo olufakwe kumzila wesitimela luqinisekisa ukusebenza kakuhle kwimigama emide, ifanelekile kwi-high-frequency kunye ne-volume-volume material handling. Ifuna ufakelo lwengoma esisigxina, efuna ukulungiswa kwesiza esithile, kodwa phakathi koluhlu lukaloliwe, ukusebenza kakuhle kunye nokhuseleko luphezulu.
♦I-Rubber-Tired Gantry Crane:I-gantry cranes ediniweyo yerabhaukuthembela kumatayara ngenkxaso, enikezela ukuhamba okuguquguqukayo kunye nokuzimela kumzila osisigxina. Banokusebenza kwiziza ezingalinganiyo okanye zexeshana, njengeendawo zokwakha, iiprojekthi zebhulorho, okanye iiyadi zolungiselelo lwexeshana, ezinesakhono sokuphakamisa ngokubanzi phakathi kwe-10 kunye ne-50 yeetoni. Uyilo oludityanisiweyo lwerabha luvumela ukufuduka lula kunye nohlengahlengiso, olufanelekileyo kwiindawo ezineendawo zokusebenza ezihlala zitshintsha. Nangona kunjalo, isantya sentshukumo siyacotha kwaye uzinzo lungaphantsi kancinane kuneekhreyini ezixhonywe kuloliwe, ezifuna ukusebenza ngononophelo. Zikulungele ukusebenza kwexesha elifutshane okanye iindawo ezininzi kunye nokunciphisa imfuno yeziseko ezisisigxina.
Uhlobo ngalunye lwe-gantry crane luneempawu ezizodwa kunye nezicelo. Ukukhetha i-gantry crane efanelekileyo kufuna ukuqwalaselwa kwamandla okuphakamisa, iimeko zesayithi, ukuphindaphinda kokuphatha, kunye nohlahlo lwabiwo-mali. Ukukhethwa ngokufanelekileyo kunye nokusetyenziswa kwe-gantry cranes ayikwazi nje ukuphucula ukusebenza kakuhle kodwa nokuqinisekisa ukhuseleko kunye nezixhobo zokusebenza ixesha elide, ukuhambisa izibonelelo zexesha elide kumashishini.
