Construct method of the suspension bridge girder and construction equipment of the suspension bridge girder

摘要

The present invention relates to a method of constructing a suspension bridge girder and a construction equipment of a suspension bridge girder, comprising the steps of: laying a tramway loop and a catwalk rope on pillar towers spaced apart from each other; Laying a pair of main cables using the tramway loop and the catwalk rope; Laying a plurality of hanger ropes spaced apart from each other on the pair of main cables; Laying a pair of conveying guide ropes for moving the bridge girder between the pagodas; Installing guide rope support saddles coupled to the bridge girders at the tip of each hanger rope; And transporting the bridge girder to a position where the bridge girder is to be installed along with the conveying guide rope, thereby assembling the guide girder with the guide rope supporting saddle.
