- Technology for spans between piers of up to 200 m: riverbeds, road junctions, railroad crossings, etc.
- Advisable for pier heights exceeding 50 m.
- Construction works at bridge decks in small areas. Global safety.
- Variable distances between spans possible.
- Variable deck depths possible.
- Hydraulic drive. Repeated movements.
- Radii of curvature greater than 750-1000 m.
- The bridge must be designed to withstand the loads arising from the construction.
