The present invention relates to a foldable crane capable of container shipping. A girder is composed of a first girder on a left side, a second girder on a right side, and a third girder on the center. The first girder and the second girder are installed to be detachable to each other as flange-coupled to both ends of the third girder, and components installed in the first girder, the second girder, and the third girder are foldable to closely be contacted to the first girder, the second girder, and the third girder. Therefore, the girder, which is a heavyweight oversized equipment, is separated into the first girder, the second girder, and the third girder. The volume of assembly for the first girder, the second girder, and the third girder is minimized as components such as a saddle, an inspection deck, a walkway handrail, or the like installed in the separated first girder, second girder, and third girder folded and closely contacted to the girder, and can be packaged per unit inside a standardized container space accordingly. Consequently, general container shipping is available without the need for special transportation on land as well as sea as the heavyweight oversized long crane can be separated and packaged per unit in a container, and shipping costs and shipping time are accordingly greatly reduced. |
