HiEx CONA Saddles

HiEx CONA Saddles

BBR HiEx is a saddle system for both suspended and extradosed bridges. The system completely eliminates the problems associated with standard friction saddles and, at the same time, allows for a compact and slender pylon. From a technical standpoint the HiEx Saddle is a fusion between the BBR CONA CMI internal post-tensioning system and the BBR HiAm CONA strand stay cable system.
