The Double Girder Overhead Crane ndi makina odabwitsa omwe asintha mafakitale.Chopangidwa kuti chinyamule katundu wolemetsa mosavuta komanso molondola, crane iyi imapereka magwiridwe antchito osayerekezeka komanso chitetezo pakugwiritsa ntchito zinthu.Ndi zomangamanga zawo zolimba komanso zotsogola, ma cranes oyenda pamwamba apawiri amawonekera m'kalasi mwawo ndipo ndi chisankho choyamba m'mafakitale ambiri.
Umodzi mwaubwino wa ma cranes oyenda pamwamba pa ma girder okwera pamwamba ndi kuthekera kwawo kwapadera.Zingwe ziwiri za crane zili m'mphepete mwa mlathowo, zomwe zimapangitsa kuti pakhale bata komanso mphamvu.Imatha kunyamula katundu wolemera kuchokera ku matani angapo mpaka matani mazana angapo, ndikupangitsa kuti ikhale yabwino kwa mafakitale omwe amagwira ntchito zazikulu komanso zazikulu.Kaya mukupanga, kumanga kapena mayendedwe, crane iyi ili ndi mphamvu ndikutha kuthana ndi zofunikira zogwirira ntchito.
Kuwonjezera pa katundu wochititsa chidwi, ma cranes oyendayenda a double girder overhead amaperekanso kusinthasintha kwapadera.Wokhala ndi njira zosiyanasiyana zokwezera komanso njira zowongolera, crane imapereka njira zonyamulira komanso zoyendetsera bwino.Ndi mawonekedwe ake apamwamba odzipangira okha, ogwiritsa ntchito amatha kuwongolera ndikuwunika kayendedwe ka crane, ndikuwonetsetsa kuti zinthu zikuyenda bwino.Kuphatikiza apo, ma cranes oyenda pamwamba pa girder amatha kupititsa patsogolo magwiridwe antchito awo ndikuphatikiza zida zothandizira monga ma grabs, maginito kapena zonyamulira kuti zigwirizane ndi zofunikira zamakampani.
Chitetezo ndi nkhani yofunika kwambiri m'mafakitale aliwonse ndi ma cranes apawiri okwera pamwamba pankhaniyi.Zimapangidwa ndi zida zotetezedwa zomwe zimaphatikizidwa ndi chitetezo chochulukirachulukira, batani loyimitsa mwadzidzidzi ndi mabuleki olephera kuonetsetsa kuti ogwira ntchito ndi ogwira ntchito ali ndi moyo wabwino.Kumanga kolimba kwa crane ndi zida zapamwamba zimatsimikizira kugwira ntchito kwanthawi yayitali ndikuchepetsa mtengo wokonza ndi kukonza pakapita nthawi.Kuphatikiza apo, ma cranes oyenda pamwamba pa girder amatha kukhala ndi njira zowunikira komanso zowunikira kuti azindikire zovuta zilizonse zomwe zingachitike, zomwe zimalola kukonza mwachangu ndikuchepetsa nthawi yopuma.
