The importance of the slide beam for incremental launching construction is self-evident, and the slide beam needs to be hoisted to the bottom of the steel truss beam.
[0003] Usually, floating cranes are used for hoisting construction on the river surface. However, how to drop the anchor and walk the anchor during floating crane construction is greatly affected by the surrounding construction environment, especially difficult for operations in the navigable area. Secondly, the installation of the slide beam is generally symmetrically installed on the upstream side and the downstream side. When any one of the upstream and downstream sides is restricted by the hoisting height and the hoisting radius, it is difficult for large-scale hoisting machinery to operate, and problems such as too short boom when standing on the upstream side to hoist the downstream side and inability to hoist often occur, thus increasing the hoisting construction difficulty of the slide beam.
