Combined guardrail and cable safety systems
View Patent ↗A combined guardrail and cable safety system is disclosed. In one aspect, a safety barrier incorporating the teachings of the present disclosure may include a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables may be releasably engaged with and supported by the cable posts. The cable posts and the at least two cables may cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts may also spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A box beam guardrail beam may be attached to the plurality of guardrail posts. The at least two cables may operably extend from the cable posts to engage respective cable anchor brackets attached to the box beam guardrail beam.
1. A safety barrier comprising:
a plurality of cable posts spaced from each other and disposed adjacent to a roadway;
at least two cables releasably engaged with and supported by the cable posts;
the cable posts and the at least two cables cooperating with each other to prevent a vehicle from leaving the roadway;
a plurality of guardrail posts spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post;
a box beam guardrail beam attached to the plurality of guardrail posts, the box beam guardrail beam having at least two faces; and
the at least two cables operably extending from the cable posts to engage respective cable anchor brackets attached to the box beam guardrail beam, the respective cable anchor brackets attached to different faces of the box beam guardrail beam such that each of the at least two cables engages its respective cable anchor bracket adjacent to different faces of the box beam guardrail beam.
2. The safety barrier of claim 1 , further comprising:
at least one of the cable posts having a slot formed therein and extending from an upper end of the cable post;
the slot operable to slidably receive the at least two cables therein; and
at least one spacer disposed within the cable post to maintain the cables at a desired location within the slot.
3. The safety barrier of claim 2 , further comprising:
at least a first cable, second cable, and third cable disposed with each slot;
a respective first spacer disposed within each cable post between the first cable and the second cable; and
a respective second spacer disposed within each cable post between the second cable and the third cable.
4. The safety barrier of claim 1 , further comprising:
at least one retaining band secured to the exterior of the post to aid in releasably engaging the cables with the cable post; and
a respective cap releasably secured with an upper end of the post.
