Abstract:Based on the 55m movable formwork of cast in place box beam construction practice of Da Yue expressway in Hunan Province , structure and technical characteristics of dual rail mounted gantry crane, steel banding hoisting mould and inner formwork assembling mould were introduced. Construction method of dual track gantry crane in 55m movable formwork of castin place box beam expounded emphatically, which could provide technical reference for the construction.
