Ke hoʻokuʻu nei i ka Girder Gantry Crane

Hoʻopili ka Bridge Girder Erecting Launcher Crane i nā alaloa nui, nā alahaka kaʻaahi i ke kahua kūkulu o ke alahaka, ʻo kāna hana nui ka haʻi ʻana i ka ʻāpana beam maikaʻi i hana mua ʻia a hāʻawi ʻia ma nā piers.it maikaʻi i hana mua ʻia a me ke ʻano laulā he nui nā koi palekana like ʻole o nā cranes.
ʻO ke Crane Hoʻāla Kūkulu Hoʻomaka Bridge Girder i hoʻokumu nui ʻia me ke kaola nui, ka cantilever, ke kaola alakaʻi ma lalo, nā wāwae mua a me hope, ka outrigger kōkua, ke crane kaola kau, ke crane cantilever a me ka ʻōnaehana uila-hydraulic. Pili i ʻekolu mau ʻāpana like ʻole o ke kūkulu ʻana i ke kaola hoʻokahi-span, me ka hana pono kiʻekiʻe.
Hoʻohana nui ʻia ka Bridge Girder Erecting Launcher Crane i ke kūkulu ʻana i nā alaloa a me ke kaʻaahi. Hoʻohana ʻia kēia mīkini no ke kūkulu ʻana i nā girders pahu sima no nā laina kaʻaahi wikiwiki (250km, 350km). He kūpono kēia mīkini no nā girders ākea like a i ʻole nā ​​girders ākea like ʻole hiki ke 20m, 24m a me 32m, 50m. Loaʻa i ka ʻaoʻao hope ʻelua kākoʻo. ʻO kekahi o nā kākoʻo he kolamu ʻano "C" me ka ʻenehana rotary a me ka pelu. Ua mālama ka ʻenehana kolamu ʻano "C" i ka hakahaka traverse i ka wā o ka huakaʻi a hiki ai ke hele ma waena o nā tunnels me ke kaʻa hoʻoili girder.
