双跨桥吊重大件码头装卸工艺与装备

在对国内外桥式起重机重大件码头装卸工艺研究的基础上，提出一种基于悬臂钢结构基础的双跨桥吊重大件码头装卸工艺。该工艺方案采用双跨重型桥吊和轻型桥吊穿越运行和大起重量悬臂钢结构基础等关键技术，已成功应用于宜宾港1 000 t重大件码头泊位建设工程中。其成功应用对长江上游地区的重大件货物的港口中转物流产生重大影响，进一步促进该地区运输业和重型工业的发展。

Heavy lift terminal handling technology based on double-span bridge crane

On the basis of the research on the handling technology of the heavy lift terminal of the bridge crane at domestic and abroad,this paper puts forward a heavy lift terminal handling technology based on the double-span bridge crane and cantilever steel structure.The key technology is to adopt the over-crossing double-span heavy bridge crane and light bridge crane and the large crane cantilever steel structure foundation.The technology has been successfully applied to the heavy lift terminal of Yibin port.The successful application brings a great impact on the port transshipment logistics of heavy lifts on the upstream Yangtze River,and further promotes the development of the regional transport and heavy industry.
