Kinematic study of folding bridge

Abstract

Over the water courses or irrigation canals different bridges may be built. These constructions can be fixed or movable (folding). Fixed bridges have the great disadvantage of hindering the movement of boats, which are higher than the bridge level, on the watercourses. In order to eliminate this disadvantage, the folding bridges can be created, which allow the opening of the navigation paths when necessary. The bridge is made up of eight segments, one of which is fixed to the base, and the other seven segments fold, so that an octagon is made.
