The present invention relates to a form traveler. Specifically, the form traveler comprises: an upper traveler installed in the upper part of a girder segment which is constructed; an upper rail installed on the girder segment; a launching unit connecting the upper traveler and the upper rail and moving the upper traveler, the upper rail, or both of the upper traveler and the upper rail; a lower traveler connected to the upper traveler and installed in the lower part of the segment, wherein a mold is installed in the lower traveler; and a driven unit connected to the girder segment and the lower traveler and moving the lower traveler when the upper traveler is moved by the launching unit. The multipurpose form traveler is used for a concrete cable-stayed bridge as an upper road type form traveler and a lower road type form traveler are integrated so that the form traveler can be used regardless of the shape of a cross section of an outer wall of a girder used for the concrete cable-stayed bridge. |
