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.
