Cable Barrier Systems are high-tension steel wire rope barriers installed along highway medians and roadsides for vehicle containment. Unlike rigid barriers, they manage vehicle impact through the tension and deflection of flexible steel cables, helping catch and decelerate an errant vehicle.
The source also positions cable barriers as an option where motorcyclist protection and a lower barrier profile for maintaining road sight lines are important considerations.
Key Specifications:
- Three-strand or four-strand steel wire rope systems
- Configuration selected according to required containment level
- High-tension post and anchor installation
- Designed to maintain correct cable tension
- Terminal anchor assemblies at all barrier endpoints
- Wider post spacing than W-Beam Guard Rail, reflecting cable-barrier deflection characteristics
- Requires regular cable tension inspection
- Cable tension adjustment included as part of the maintenance programme
