The "Jack-Up Rotating Erection Method" is a construction technique where steel girders are sequentially assembled alongside bridge piers using jacks, and after assembly is complete, the girders are rotated and erected using wire ropes. Using the jack-up equipment installed at the base of the bridge pier, the main girder is raised, and then the girder is inserted and joined, followed by vertical jack-up along the bridge pier. This series of operations is repeated to attach the girder to the rotation pin at the top of the bridge pier. Please feel free to contact us if you have any inquiries. 【Features】 ■ Suitable for superstructure erection with high bridge piers ■ Effective when planning adjacent areas of the bridge for launching yards is difficult ■ A method that minimizes high-altitude work ■ Suitable for the erection of small main girder bridges *For more details, please feel free to contact us.

The "Lift-Up Horizontal Rotation Construction Method" involves lifting up the pier and beam section, and then rotating it horizontally after connecting it to the columns. This method allows for the installation of piers under elevated bridges in construction conditions where there are strict limitations above, to the sides, and in front, such as those found in areas squeezed between roads. Please feel free to contact us if you have any inquiries. 【Features】 ■ Construction can be done with low noise ■ Significant reduction in traffic restrictions ■ Reduction of high-altitude work is possible ■ Shortening of construction period is possible *For more details, please download the PDF or feel free to contact us.
