摘要

The present invention relates to a downward form traveler. The downward form traveler includes a reverse c-shaped transverse upper support frame which is installed to move along an upper rail forward and backward in the throttle direction and includes an upper end support frame and both side support frames formed on side ends; a main frame which is in the shape of a triangular truss having a center weight line matching the center weight line of the transverse upper support frame and is connected to both side support frames of the transverse upper support frame to move with the side support frames; a rear support balance installed to prevent the main frame from falling into the front; and an upper inner guide rail which is installed on the guide rail to extend from the inner and lower surface of an upper flange of a girder in the throttle direction.
