JP75 Precast Segmental Launching Gantry
Project name: Babahoyo River Bridge, Guayaquil City, Ecuador
Project introduction: Babahoyo River Bridge project is located in Guayas Province, Ecuador, it is the cross-river bridge between Duran City and Guayaquil City with total length of 2,185m, and there are 26 main bridge piers, it needs to set up 26-span beam segments. The whole bridge section includes 2.35% uphill section and 3.4% downhill section. The main bridge is a prefabricated suspending 75m span continuous box girder, and the bridge approach at both sides is pre stress T beam with 30m span.
Span combination: 3x30m+50m+25x75m+50m+4x30m=2,185m. This bridge main girder single arrangement is pre stress concrete continuous box girder, the main girder section is single box single room inclined web box type section, box girder roof is 20.8 meters wide and box girder bottom is 8.0-9.115m wide and 4.25-3m high, thickness of web is 45cm, there is 2% cross slope on the box top. This bridge erecting machine is applied to the installation of 572 pieces of beam section of this project.
