DYWIDAG’s DYNA Grip Stay Cable System is suitable for heavy road and rail bridges.
The DYNA Grip Stressing Anchorage consists of an anchor block in which the strands are anchored by high fatigue 3 part-wedges. A ring nut is threaded onto the anchor block to transmit the cable force into the structure via the bearing plate. A steel pipe that incorporates bending and sealing provisions for the strands is part of the anchor block. A non-adjustable anchorage with the same provisions for bending and sealing of the strands can be placed at the dead-end side.
Redaelli Engineering Division, as Tensoteci, started its activity to introduce tensostructuresIn Italy from 1972, with the scope to perform all the activities from design to manufacture.
Redaelli Engineering Division is now a leader in this market and offers complete technical solutions, including cable installation and maintenance services for all types of Tensostructures.
Redaelli systems are suitable for structures such as pedestrian bridges, stadia, roofing systems and observation wheels.
Redaelli offer both open spiral strands or full locked coil strands.
Open Spiral Strands
These are made with hot dip galvanised high strength steel wires.The strand is made up of several layers of round wires helically wound around the coil. The typical main properties of the wires
conform to the EN 12358-10.
Fully Locked Coil Strands
These are made with hot dip galvanised high strength steel wires.The strand is built with an inner core made of round wires and by one or more external layers of Z shaped wires. The wires are shaped equalling them to the self-locking and also to achieve a compact section.The principal characteristics of resistance and corrosion protection of the wires conform with EN 12385-10.
