A wire rope safety barrier comprising a plurality of line posts positioned along a roadway. A plurality of cables are attached to the line posts and extend between the line posts to define a safety barrier along the roadway. At least one of the plurality of cables is an external cable engaging an outer surface of the line posts. Each external cable is connected to the line posts by a cable holder inserted through the cable holder slot, and the cable holder has a body portion and a hook portion. Each cable holder has a locating notch at a bottom surface configured to engage with the lower edge of a corresponding cable holder slot.

A safety barrier comprises a plurality of posts spaced from each other and disposed adjacent to a roadway, each post having a cross section defined in part by a web and a pair of legs extending therefrom. Additionally, each post has one slot formed in the web of the post extending from an upper end of the post. A first cable and a second cable are releasably engaged with and supported by the posts and disposed within each slot between the respective legs of each post. A third cable and a fourth cable are each coupled to an exterior surface of the posts. The posts and the first, second, third and fourth cables cooperate to prevent a vehicle from leaving the roadway.

A road safety barrier has a plurality of panels flanking one another at respective vertical lateral edges thereof, made of a material deformable upon impact by a vehicle, and a plurality of vertical support elements supporting the panels. The vertical support elements include a first and a second vertical support member facing one another at the flanked vertical lateral edges of the panels, on opposite sides with respect to two major faces of the panels. The barrier has components for reciprocally blocking the first and the second vertical support member to the two opposite faces of the panels, and longitudinal stiffening elements coupled to the panels at respective upper longitudinal edges thereof.

Provided is a wire rope with resin wire, including a wire rope body in which a plurality of strands are twisted together, and at least one resin wire spirally wound around the wire rope body along a recess between the strands. Strand grooves into which the strands can fit and a resin wire groove into which the resin wire can fit are formed spirally along the twist of the wire rope with resin wire, in a winding hole of a resin wire winding die used for winding the resin wire around the wire rope body. As a result, the resin wire can be easily and reliably mounted on the wire rope body and a wire rope with resin wire can be thus produced.

Disclosed is a barrier, comprising: a plurality of posts; a first beam and a second beam arranged in an end-on relation to one another and extending between respective posts of the plurality of posts, wherein the first beam and second beam are longitudinally displaceable with respect to one another; and, an articulating link connecting the first beam and the second beam, wherein the articulating link translates a longitudinal movement of the first beam in a first direction to a longitudinal movement of the second beam in a second direction.

A protective barrier includes a first end piece configured to be anchored and secured to a surface, a second end piece configured to be anchored and secured to the surface, a rail extending between the first end piece and the second end piece, and a cable extending through the rail and having a first end attached to the end piece and a second end attached to the second end piece. The rail has a first end mechanically coupled to the first end piece and a second end mechanically coupled to the second end piece.

A cable barrier system is managed by a cable barrier management system including a management system controller having a management processor, a wireless data communications interface, and a plurality of turnbuckle subsystems configured to be joined to respective barrier cables to provide pretension. Each of the turnbuckle subsystems has a strain gauge mounting zone and is configured to enable communication of strain from a strain gauge circuit to the management processor. The management system controller includes a sensing circuit to receive the strain gauge output voltage from the strain gauge circuit and provide sensing circuit output to the management processor. The management system controller includes a cable barrier analysis module configured to determine excess strain events. The management processor generates strain event data, which is sent via the wireless data communications interface to a remote recipient computing device.
