Wire rope safety barrier systems, also known as cable barriers rely upon the tensile strength and deflection of wire cables to contain and redirect errant vehicles. Wire rope safety barriers are configured with four (4) cables supported by steel posts spaced every 2m to 3m. The posts are positioned within a plastic sleeve that is concreted into the ground facilitating removal of the damaged post following design impacts.
At each end of the wire rope safety barrier system the wire cables are tapered to ground level and secured to an anchor bracket that is concreted into the ground.
The deflection of wire rope safety barriers provide stable vehicle containment and low ride-down decelerations for vehicle occupants. Wire rope safety barriers are widely recognised for preventing dangerous head-on collisions on major highways and freeways.
