The invention relates to the technical field of building machinery, aims to solve the problem that a portal crane is difficult to assemble in a construction area with a narrow space, and provides a portal crane system and a reshipment and installation method thereof. A working extension section extending in the same direction as the working track is arranged at the butt joint position of the working track and the transfer track, a transfer extension section extending in the same direction as the transfer track is arranged at the butt joint position of the transfer track and the working track, and the first supporting arm and the second supporting arm are installed at the two ends of the main beam respectively. A rolling device and a hydraulic lifting component are installed at the bottom of the first supporting arm and the bottom of the second supporting arm respectively, the rolling device can roll in the transfer track, the transfer extension section, the working track and the working extension section, and the assembling work of the portal crane can be flexibly completed in a construction area with narrow space and poor site conditions. Manpower and material resources for assembling the portal crane are saved, and the application range of the portal crane is expanded.
