Described herein is an impact device that may be slidably coupled to a wire rope barrier terminal end and, in the event of an impact on or about the terminal end by a vehicle, the impact device is configured to slide or advance along the terminal end wire rope(s) towards a wire rope barrier end and away from a terminal end anchor position. In a further embodiment, a method is described of retrofitting existing wire-rope barrier terminal ends with the device. The impact device may simultaneously (at least to some extent) absorb kinetic energy from the impact as well as redirect the direction of impact along the terminal end wire rope(s) towards, and optionally along, the wire rope barrier itself depending on the extent of impact. The sliding action also knocks over any posts in the direction of errant vehicle travel in an impact.

A barrier cable coupler for coupling two lengths of barrier cable comprises a coupler body including a threaded inner surface, a first end, and a second end; a fixed retaining collar having an outer surface and being retained to the first end of the coupler body, the fixed retaining collar including a tapered inner surface; one or more fixed end wedges positioned within the tapered inner surface of the fixed retaining collar; a tensioning retaining collar having an outer surface, the tensioning retaining collar positioned at least partially within the second end of the coupler body and including a tapered inner surface; one or more tensioning end wedges positioned within the tapered inner surface of the tensioning retaining collar; and a tensioning nut including a threaded outer surface engaging the threaded inner surface of the second end of the coupler body and retaining the tensioning retaining collar therein.

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.

A method for releasing at least one anchor cable from a terminal post in a cable barrier, after an inline impact, including deforming the terminal post from a straight upright configuration to a bent inclined configuration where the deformation creates a suitably sized aperture in the post which enables release of the anchor cable.

A crash barrier is provided. The crash barrier includes a plurality of supports, a guard rail, and connection parts which are inclined so as to mutually connect the supports and the guard rail at certain intervals, such that an impact energy-absorbing capacity can be improved by preventing impact energy from being directly applied to the supports in a direction orthogonal to the guard rail.
