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
