I-double girder bridge crane yakhiwe ngemishayo emibili yebhuloho enamathiselwe kwithrekhi, futhi imvamisa ihlinzekwa ngamalifti etrolley kagesi ebamba phezu kwentambo, kodwa ingase futhi ihlinzekwe ngamakheji kagesi angaphezulu kwaphezulu kuye ngokuthi isisetshenziswa. I-SEVENCRANE Overhead Cranes kanye nama-Hoists anganikeza ama-cranes amabhuloho e-single girder ukuze asetshenziswe ngokujwayelekile, futhi anikeze ama-cranes amabhuloho amabhuloho akhiwe ngokwezifiso ezimboni ezihlukahlukene. I-double girder bridge crane iphinde isetshenziswe ngaphakathi noma ngaphandle, noma kumabhuloho noma ekucushweni kwe-gantry, futhi ivamise ukusetshenziswa ezimayini, ekwenziweni kwensimbi nensimbi, emagcekeni esitimela, nasezikhumulweni zasolwandle.
I-double girder bridge crane ivamise ukudinga imvume enkulu ngaphezu kokuphakama komzila we-crane njengoba amaloli e-lift enqamula phezulu kwe-cranes bridge girder. Okhreni begida elilodwa bahlinzeka ngama-engeli angcono wokusondela kukho kokubili indawo yokukhuphuka nohambo lwebhuloho kunama-double girder cranes. Nakuba kungavamile ukubonakala, ibhuloho elinamabhinca amabili elingaphansi kwe-crane lingase linikezwe ihuku le-trolley egijima phezulu. Ama-cranes amabhuloho amabhilidi amabili ahlanganisa imishayo emibili yebhuloho enamathiselwe kwithrekhi, futhi ngokuvamile ahlinzekwa ngezintambo ezihamba ngezintambo ezihamba ngogesi ezihamba ngogesi, kodwa angase ahlinzekwe ngamaketanga ahamba phambili ahamba ngogesi kuye ngokuthi isetshenziswa kanjani.
Ngokusebenzisa amasistimu amanje okubala, ama-SEVENCRANE Double Girder Overhead Cranes angakwazi ukulungisa isisindo sawo ukuze anciphise amandla abekwe esakhiweni ngemithwalo yawo, kuyilapho futhi ethuthukisa ukuqina kwedivayisi yokuphakamisa ngesikhathi sokulayisha umthamo omkhulu wempahla. Njengoba ububanzi be-crane yebhuloho namandla anda, amagida ane-flanged abanzi azokhuphula ukujula okudingekayo (ubude bebhande) nesisindo ngonyawo ngalunye. Isakhiwo esiyisisekelo se-crane yokuhamba phezulu egibele ibhuloho ukuthi amaloli agijima ngamasondo ehle ngobude besistimu yethrekhi, anebhande lekhebula lebhuloho elifakwe elolini elisekupheleni, futhi amaloli ama-boom amise ama-boom, ahamba ngapha nangapha. i-span. Ama-cranes angaphezulu nge-GH Cranes & Components atholakala ngezitayela ezimbili, i-box-girder kanye namaphrofayili ajwayelekile, futhi afakwe umshini wokuphakamisa owakhelwe ngaphakathi, ngokuvamile kungaba i-hoist noma i-hoist evulekile.
