Collapsible Bridge

Over the water courses or irrigation canals, different bridges may be built. These constructions can be fixed or folding. Fixed bridges have the disadvantages of hindering the movement of boats which are higher than the bridge level on the watercourses. In order to eliminate this disadvantage, the folding or collapsible bridges can be created, which allow the opening of navigation paths whenever necessary. The bridge is made up of two portions, of which one part is movable and the other one is fixed.
