Ama-cranes e-Gantryziyizinhlobo zemishini yokuphakamisa esetshenziselwa imisebenzi yangaphandle emagcekeni ezimpahla, ezitokisini, ukuphatha imithwalo eyinqwaba, kanye nemisebenzi efanayo. Isakhiwo sazo sensimbi sifana nohlaka olumise okomnyango, olukwazi ukuhamba ngamathrekhi angaphansi, ngothango oluyinhloko olufakwe ngokuzithandela ngama-cantilever kuzo zombili iziphetho ukuze kwandiswe ububanzi bokusebenza. Ngenxa yesakhiwo sabo esizinzile nokuvumelana nezimo okuqinile, ama-gantry cranes asetshenziswa kabanzi emachwebeni, ezitimeleni, ezimbonini nasezindaweni zokwakha.
Ama-cranes e-Gantry angahlukaniswa ngezindlela ezihlukahlukene:
Ngesakhiwo:ibhande elilodwa noma ibhande eliphindwe kabili
Ngokucushwa kwe-cantilever:i-cantilever eyodwa noma i-double cantilever
Ngohlobo losekelo:umzila wesitimela noma ukhathele ngerabha
Ngokuphakamisa idivayisi:ihuku, ibhakede lokubamba, noma i-electromagnetic
I-double main beam hook gantry craneiyisisetshenziswa esithwala kanzima, esisetshenziselwa ukulayisha nokuthulula impahla emachwebeni, emayadini ezimpahla nakwezinye izindawo. Isakhiwo sawo siqukethe imishayo emibili eyinhloko ehambisanayo, ama-outrigger namahhuku ukuze kwakhe uhlaka lwephothali. Idizayini ye-double girder ithuthukisa umthamo wokuthwala umthwalo nokuzinza, futhi ifanele indawo enkulu yokusebenza, imithwalo esindayo. Ihhuku ingaphakanyiswa futhi yehliswe iqonde futhi ihambise kalula izinto ezisindayo. I-crane inezici zokusebenza kahle kakhulu, ukuphepha kanye nokuvumelana nezimo okuqinile, futhi isetshenziswa kabanzi embonini, kwezokuthutha kanye neminye imikhakha.
Indawo evamile yokusetshenziswa kwe-double main beam hook gantry crane kufanele ibe phakathi kwebanga elingu -25ºC ~ + 40ºC, futhi izinga lokushisa elijwayelekile phakathi kwamahora angama-24 akumele lidlule ku-35ºC. Akulula ukusebenza emithonjeni yabezindaba evuthayo neziqhumayo noma ezindaweni ezinomswakama ophezulu namagesi abolayo. Inezinhlobonhlobo zezicelo emsebenzini wasensimini, izinto zokubamba, ukusebenza kwefekthri nezokuthutha.
Lapho isebenza ensimini, ingasebenza ngaphansi kwezimo zezwe eziyinkimbinkimbi namandla ayo okuphakamisa aqinile kanye nesakhiwo esizinzile. Isibonelo, ezimayini ezinkulu ezivulekile, ikwazi ukuphakamisa kalula izinto ezisindayo njengensimbi.
Mayelana nezinto zokubamba, kungakhathaliseki ukuthi yizinto zensimbi, ukhuni noma izinto ezenziwe ngaphambili,ama-gantry cranesingakwazi ukubamba ngokunembile futhi ingashintshwa ukuze ihambisane nemishini yokuphakamisa ehlukahlukene ukuze ihlangabezane nezidingo ezihlukile zokuphakamisa.
Ngaphakathi efektri, iwumshini oyinhloko wokuphatha izinto ezibonakalayo. Kusukela ekuphakanyisweni kwezinto zokusetshenziswa kuya endaweni yokucubungula kuya ekudlulisweni kwemikhiqizo eqediwe endaweni yokugcina impahla, i-double main beam hook gantry crane ibamba iqhaza kuyo yonke inqubo yokuqinisekisa inqubo yokukhiqiza ebushelelezi.
Kusixhumanisi sezokuthutha, ezikhumulweni zemikhumbi, amapaki okuthutha nezinye izindawo, ama-gantry cranes angalayisha ngokushesha futhi ehlise izimpahla ezimotweni zokuthutha noma emikhunjini ukuze kusheshiswe ukushintshwa kwempahla.
Izici Nokuphakamisa Ukusebenza Kwezinhlobo Ezihlukene Ze-Gantry Cranes:
♦ I-Single Girder Gantry Crane:I-Single girder gantry cranesbabe nesakhiwo esilula, isisindo esincane, kanye nezindleko eziphansi zemishini kanye nokugcinwa. Zilungele iziza ezincane kanye nokusebenza okungamathani aphansi, njengamafekthri, izindawo zokugcina izimpahla, noma amadokodo amancane, anamandla okuphakamisa ngokuvamile asukela kumathani angu-5 kuya kwangu-20. Ngenxa yesakhiwo sazo esingasindi, ukufakwa nokuthutha kulula, futhi ukusebenza kuyavumelana nezimo, okubenza bafanelekele ukuphatha imithwalo elula njalo. Kodwa-ke, umthamo wabo wokuthwala umthwalo unomkhawulo, okubenza bangakufanelekeli ukusebenza okuqinile noma okuqhubekayo kwe-high-tonnage.
♦ I-Double Girder Gantry Crane:I-double girder gantry cranesihlanganisa isakhiwo esiyinkimbinkimbi, isisindo esiphezulu esiphezulu, kanye nezindleko eziphezulu zemishini kanye nokugcinwa, kodwa inikeza umthamo oqinile wokuthwala umthwalo. Zifanele iziza ezinkulu kanye nokusebenza kwe-high-tonnage, njengezigayo zensimbi, izitshalo zikasimende, namayadi amalahle, anamandla okuphakamisa ngokuvamile asukela kumathani angama-20 kuye kwangama-500. Isakhiwo se-double girder sinikeza ukuzinza okukhulu nokuphepha, ukusekela amadivaysi amakhulu okuphakamisa kanye nemisebenzi eyinkimbinkimbi, elungele ukuphathwa okude kwezinto ezisindayo. Ngenxa yesakhiwo sabo esikhulu, ukufakwa kuthatha isikhathi eside futhi izidingo zesayithi ziphakeme.
♦ I-Rail-Mounted Gantry Crane:Ama-gantry cranes afakwe ujantshizisekelwa kumathrekhi, zinikeza ukuzinza okuhle kakhulu kokuhamba nokuzivumelanisa nezimo. Asetshenziswa kakhulu kumayadi wempahla angaphandle, amasitoko, kanye nokuphathwa kwempahla eyinqwaba emachwebeni, ezimbonini zikagesi, noma ezikhumulweni zesitimela, ezinekhono lokuphakamisa ngokuvamile lisuka kumathani angu-5 kuye kwangama-200. Idizayini efakwe ujantshi iqinisekisa ukusebenza okushelelayo kumabanga amade, ifanele ukuphathwa kwempahla yevolumu ephezulu kanye nevolumu enkulu. Kudinga ukufakwa kwethrekhi engaguquki, okudinga ukulungiswa kwesizinda esithile, kodwa phakathi kwebanga likaloliwe, ukusebenza kahle nokuphepha kuphezulu.
♦ I-Rubber-Tired Gantry Crane:Ama-gantry cranes akhathele yirabhathembela emathayini ukuze uthole ukwesekwa, enikeza ukuhamba okuvumelana nezimo nokuzimela kumathrekhi angashintshi. Angasebenza ezindaweni ezingalingani noma zesikhashana, njengezindawo zokwakha, amaphrojekthi wamabhuloho, noma amayadi ezinto zesikhashana, anamandla okuphakamisa ngokuvamile aphakathi kwamathani ayi-10 nama-50. Idizayini ekhathele yenjoloba ivumela ukuthutha nokulungiswa kalula, kulungele amasayithi anezindawo zokusebenza ezishintsha njalo. Kodwa-ke, isivinini sokunyakaza sihamba kancane futhi ukuzinza kuphansi kancane kunokhrayini abagibele kajantshi, okudinga ukusebenza ngokucophelela. Zilungele ukusebenza kwesikhashana noma izindawo eziningi futhi zinciphisa isidingo sengqalasizinda ehlala njalo.
Uhlobo ngalunye lwe-gantry crane lunezici ezihlukile kanye nezinhlelo zokusebenza. Ukukhetha i-gantry crane efanele kudinga ukucatshangelwa amandla okuphakamisa, izimo zesayithi, imvamisa yokusingatha, kanye nesabelomali. Ukukhetha okufanele nokusetshenziswa kwama-gantry cranes akukwazi nje ukuthuthukisa ukusebenza kahle kodwa futhi kuqinisekise ukuphepha kanye nokuphila isikhathi eside kwemishini, ukuletha izinzuzo zesikhathi eside zamabhizinisi.
