[0002] High-pier, low-curvature cast-in-place box girders are used in mountainous and hilly areas with extremely complex and varied terrain. These girders exhibit significant elevation changes, necessitating the installation of scaffolding on them for construction. Therefore, construction scaffolding devices for high-pier, low-curvature cast-in-place box girders are crucial construction equipment. However, existing construction scaffolding systems for high-pier, low-curvature cast-in-place box girders are currently limited by the height of the scaffolding erected on the high piers, thus affecting the construction efficiency.
