I-Double Girder Overhead Craneiyi-crane yebhuloho elungele ukusebenza kwangaphakathi noma ngaphandle kwe-span fixed, futhi isetshenziswa kabanzi ekuphatheni nasekuthuthweni kwezinto ezisindayo ezahlukahlukene. Idizayini yayo eqinile kanye nesakhiwo esizinzile kufaneleka ikakhulukazi ezindaweni zokusebenza ezidinga ukuma okunembayo nokuhlanganisa okusindayo.
Uma kuqhathaniswa ne-single-beamibhulohoama-cranes,ama-cranes ama-double girder overheadzinesakhiwo esiqinile, umthamo oqinile wokuthwala umthwalo, futhi ziphephe kakhudlwana ukuzisebenzisa. Ngakho-ke, uhla lwamandla okuphakamisa lubanzi, futhi lungathwala izinto ezisindayo ukusuka kumathani ama-3 kuye kwangama-50. Ubude baso singalungiswa ngokuya ngezidingo ezithile, kusuka kumamitha ayi-10.5 kuya kumamitha angama-31.5, futhi ukuphakama kwayo kokuphakanyiswa kusuka kumamitha ayi-6 kuye kwangamamitha angama-30, okungahlangabezana nezidingo ezahlukahlukene zokusebenza. Intengo ye-double girder overhead crane ithonywa izici ezifana nomthamo womthwalo, ubude besikhathi, nezici zangokwezifiso, okwenza kube semqoka ukuthola isilinganiso esinembile.
Imodi yokusebenza ye-crane ingakhethwa ngokuvumelana nezimo ezithile zesayithi, kuhlanganise nokusebenza komhlabathi, ukusebenza okukude, nokusebenza kwekhebhu. Njengoba ama-cranes ama-double girder overhead ngokuvamile anezipani ezinkulu, amandla amakhulu okuphakamisa, kanye nokuphakama okuphezulu, ukusebenza kwekhebhu kuvame ukuncanyelwa ukuze kuqinisekiswe ukuzinza nokuphepha komsebenzi.
Ii-double girder eot craneilungele ikakhulukazi izindawo zokusebenza ezidinga ukuma okunembe kanye nokuhlanganisa izingxenye ezinkulu. Umthamo wayo oqinile wokuthwala imithwalo kanye nohlu olubanzi lwezinhlelo zokusebenza kuyenza ibe umshini obalulekile nobalulekile ezimbonini ezihlukahlukene. Kungakhathaliseki ukuthi izinkundla zokusebenzela zokukhiqiza imishini esindayo, izitshalo ze-metallurgical, noma ama-workshops okukhiqiza ama-electronic adinga ukusebenza okunembayo okuphezulu, inganikeza ukusebenza okuhle kakhulu nokuthembeka.
Ngokukhetha i-double girder eot crane, abasebenzisi bangathuthukisa kakhulu ukusebenza kahle kokuphatha impahla ngenkathi beqinisekisa ukuphepha kokusebenza. Izindlela zayo zokusebenza eziningi, umthamo oqinile wokuthwala umthwalo kanye nomklamo wesakhiwo oguquguqukayo kuwenza ube umshini wokuphakamisa okhethwayo ezimbonini eziningi. Ukuxoxisana ngeI-double girder overhead crane intengokungaholela ekongeni okukhulu, ikakhulukazi uma uthenga ngobuningi noma kumaphrojekthi amakhulu.
