Ii-double girder overhead craneiyimishini yokuphakamisa umsebenzi osindayo esetshenziswa kabanzi ekukhiqizeni izimboni, eyenzelwe ukuqina, izindawo zokusebenza ezisetshenziswa njalo. Isekelwa yimishayo emibili eyinhloko futhi ingathwala isisindo esikhulu.
Ii-double girder overhead craneinomthamo oqinile wokuthwala futhi ngokuvamile ingaphatha izinto ezisukela kumathani ayi-10 kuya kumathani angama-500 nangaphezulu. Lokhu kwenza kube ukukhetha okuhle kwemishini esindayo kanye nokuphathwa kwezinto ezinkulu ekukhiqizeni izimboni. Uma kuqhathaniswa nama-cranes angaphezulu kwegirder eyodwa, ama-cranes ane-double girder angakwazi ukusekela izikhala ezinkulu kanye nokuphakama okuphakeme kokuphakamisa, ukuzivumelanisa nezimo ezihlukahlukene zokusebenza eziyinkimbinkimbi.
Okukabili ibhandeethi uhlaka lwe-crane olunemishayo emibili lunikeza ukuzinza okuphezulu, ikakhulukazi uma uphakamisa isisindo esiningi noma izinto ezimise ngendlela engavamile. Ngesikhathi esifanayo, ifakwe uhlelo lokulawula ukunemba okuphezulu olungafinyelela ukusebenza okunembile kwe-crane ukuze kuqinisekiswe ukuphatha okubushelelezi nokuphephile.
Umklamo weibhande eliphindwe kabiliethi i-cranekungenziwa ngokwezifiso ngokuya ngezidingo ezithile zohlelo lokusebenza, okuhlanganisa ukuphakama kokuphakamisa, ubude besikhathi, umthamo womthwalo kanye nethrekhi yokuhamba. Abasebenzisi bangakhetha ukucushwa kwemishini efaneleke kakhulu ngokwesimo sangempela sesizinda somsebenzi wabo, ukuze kukhuliswe ukusebenza kahle kokukhiqiza.
I-double girder bridge cranengokuvamile ifakwe izici ezihlukahlukene zokuphepha, njengokuvikela ukulayisha ngokweqile, isistimu yokunqanda ukushayisana kanye nedivayisi yokumisa izimo eziphuthumayo. Lawa madivaysi okuphepha anganciphisa ngempumelelo ubungozi bokusebenza futhi aqinisekise ukuphepha kwabasebenzi namathuluzi. I-double girder bridge crane ifakwe phezulu kwendawo yokusebenzela noma yefekthri, engahlali phansi, okwenza ngcono kakhulu izinga lokusetshenziswa kwendawo yokusebenza yeshabhu. Lo mklamo uwenza ulungele ikakhulukazi izindawo zokusebenza ezidinga indawo enkulu yomhlabathi.
I-double girder overhead craneingahlangabezana nezidingo zezindawo zokusebenza ezahlukahlukene futhi inikeze amabhizinisi izixazululo ezisebenzayo neziphephile zokuphatha izinto ngokuklama okwenziwe ngokwezifiso. Ngokukhula okuqhubekayo kwesidingo sezimboni, ama-double girder bridge cranes azoqhubeka nokudlala indima ebalulekile esikhathini esizayo ukukhuthaza ukuthuthukiswa kokukhiqiza ezimbonini ezihlukahlukene.
