BBR HiEx CONA strand saddle system
The BBR® HiEx CONA saddle system represents the newest and most modern saddle for stayed and extradosed bridges. The HiEx CONA® saddle system completely eliminates the problems associated with standard friction saddles and, at the same time, allows for a compact and slender pylon. The technical solution results from the combination of the CONA CMI internal PT system with the BBR HiAm CONA strand stay cable system.
