DYWIDAG Stay Cable Systems





History and Milestones



DYWIDAG Post-Tensioning Systems and Stay Cable Systems are world renowned for reliability and performance; they are perfectly suitable for all applications in post-tensioned construction. They embrace the whole spectrum from bridge construction and buildings to civil applications – both above and below ground. The first ever structure built with a prototype DYWIDAG Post-Tensioning System using Bars was the arch bridge Alsleben (Germany) in 1927. From that time on, DYWIDAG has continuously improved its systems to keep up with the growing demand of modern construction technology. In addition to traditional post-tensioning systems with bars, DSI offers a complete product line in strand posttensioning (bonded, unbonded and external) as well as stay-cable systems to fulfill the changing requirements in the industry today and tomorrow.

Our stay cable systems have always combined the highest safety and reliability standards with excellent economical efficiency in their research and development. Dependable corrosion protection methods, damper design, fire protection, vibration measurements and the recently developed DYNA® Force monitoring system significantly contribute to the longevity of modern construction.



DYNA GRIP STAY CABLE SYSTEMS



- Compressible sealing plates ensure water and

even vacuum tightness.

- The correct function can be checked and even

adjusted during inspection.

- A cap including filler material for the protection

of individual strands is placed in front.



DYNA LINK ANCHOR BOX SYSTEMS



- No friction problems; horizontal forces are

transferred by the anchor box.

- Cable anchorages located outside permit slender

pylon shapes.




DYNA BOND ANCHORAGE



- During the construction period - prior to

grouting the bond socket - all the applied loads

are supported directly by the wedges.

- Easy fixation of external dampers directly on

the ground stay pipe.
