II-crane ye-double girder overheadsisixhobo esinzima sokuphakamisa izixhobo ezisetyenziswa kakhulu kwimveliso yemizi-mveliso, eyenzelwe ukuqina, iindawo zokusebenza ezisetyenziswa rhoqo. Ixhaswa yimiqadi emibini ephambili kwaye inokuthwala ubunzima obukhulu.
II-crane ye-double girder overheadinomthamo oqinileyo wokuthwala umthwalo kwaye idla ngokuphatha imathiriyeli ukusuka kwiitoni ezili-10 ukuya kwiitoni ezingama-500 nangaphezulu. Oku kwenza kube lukhetho olufanelekileyo lwezixhobo ezinzima kunye nokuphathwa kwezinto ezinkulu kwimveliso yoshishino. Xa kuthelekiswa ne-cranes enye yegirder overhead, i-double-girder cranes inokuxhasa iindawo ezinkulu kunye nokuphakama okuphezulu, ukuziqhelanisa neendawo ezahlukeneyo zokusebenza ezinzima.
Isibini umbhinqoewe Isakhiwo se-crane se-double-beam sinika uzinzo oluphezulu, ngakumbi xa uphakamisa ukugqithisa okanye izinto ezibunjwa ngokungaqhelekanga. Ngelo xesha, ixhotywe ngenkqubo yokulawula echanekileyo enokuthi ifezekise ukusebenza ngokuchanekileyo kwe-crane ukuqinisekisa ukuphathwa kakuhle kunye nokukhuselekileyo kwezinto eziphathekayo.
Uyilo lweumbhinqo kabiniewe ikhreyiniingenziwa ngokwezifiso ngokweemfuno ezithile zesicelo, kubandakanya ukuphakama kokuphakama, ubude, umthamo womthwalo kunye nomkhondo wokuhamba. Abasebenzisi banokukhetha olona lungelelwaniso lwezixhobo ezifanelekileyo ngokwemeko yokwenyani yendawo yabo yomsebenzi, ukuze kwandiswe ukusebenza kakuhle kwemveliso.
Double girder ibhulorho cranengokuqhelekileyo ixhotyiswe ngeempawu ezahlukeneyo zokhuseleko, ezifana nokukhuselwa komthwalo ogqithisileyo, inkqubo yokuthintela ukungqubana kunye nesixhobo sokumisa unxunguphalo. Ezi zixhobo zokhuseleko zinokunciphisa ngempumelelo iingozi zokusebenza kwaye ziqinisekise ukhuseleko lwabasebenzi kunye nezixhobo. I-crane ye-double girder bridge crane ifakwe phezulu kwi-workshop okanye isakhiwo sefektri, esingahlali kwindawo ephantsi, iphucula kakhulu izinga lokusetyenziswa kwendawo yokusebenza yeworkshop. Olu luyilo lwenza ukuba lufaneleke ngokukodwa kwiindawo zokusebenza ezifuna indawo enkulu yomhlaba.
I-crane ephezu kwentloko ephindwe kabiniinokuhlangabezana neemfuno zeendawo zokusebenza ezahlukeneyo kwaye ibonelele ngamashishini ngezisombululo ezisebenzayo nezikhuselekileyo zokuphatha izinto ngoyilo olulungelelanisiweyo. Ngokukhula okuqhubekayo kwemfuno yemizi-mveliso, iikhreyini zeebhulorho eziphindwe kabini ziya kuqhubeka ukudlala indima ephambili kwixesha elizayo ukukhuthaza ukuphuculwa kwemveliso kumashishini ahlukeneyo.
