PURPOSE: A beam launcher with an anchorage system for constructing a bridge is provided to prevent the beam launcher from slipping when the beam launcher is moved and stopped depending on the longitudinal slope of a bridge. CONSTITUTION: A beam launcher with an anchorage system for constructing a bridge comprises girder trusses(110), a main winch(120), an auxiliary winch, a support, a horizontal rail(150), under rollers(160), a hydraulic cylinder, and anchorage systems(300). The girder trusses are arranged on the top of a pier and are moved along the horizontal rail. The main and auxiliary winches are loaded on the tops of the girder trusses. The support is installed on a coping portion of the pier. The horizontal rail is supported by the support. The under rollers are arranged on the bottoms of the girder trusses and allow the girder trusses to be slid along the horizontal rail. The anchorage systems are installed between the girder trusses and the under rollers and prevent the girder trusses from slipping. |
