Abstract: An anti-ram vehicle barrier system adapted to arrest an impacting vehicle of substantial mass within a selected distance of the barrier. The distance is approximately 36 inches for a vehicle having a mass of at least about 15,000 pounds and traveling at least about 30 mph upon impact with the barrier. The barrier system includes a fence portion and/or a gate for selectively allowing passage through an entry port. The fence portion includes a pair of terminal posts positioned in and secured to the ground in a spaced apart relationship and cables connected between the terminal posts. The gate includes a cable extending across a panel that is connected on opposing ends to opposing posts positioned on opposite sides of the entry point. For passage the panel is moved relative to the posts. The panel is moved vertically relative to the ground in some embodiments and laterally in other embodiments.

Abstract: An assembly for releasing tension in a cable includes a mounting plate holding the cable in tension, the mounting plate oriented substantially parallel to the cable when it is in tension; and a leveraging member having a base positioned between the mounting plate and the cable and a leg extending upward from the base relative to the ground surface, wherein the leveraging member leverages the cable from holding connection with the mounting plate when it is impacted with a sufficient force.

Abstract: A bollard, which is positioned in a structure having a grade level, includes an outer member having a first section extending above the grade level; an inner member having a filler material; and a connector operationally connecting the inner member and the outer member, wherein the inner member straddles the grade level and is rotatable relative to the outer member.

Abstract: An example of a vehicle barrier system for arresting an impacting vehicle of substantial mass within a selected distance of the fence includes a pair of terminal posts positioned in and secured to the ground in a spaced apart relationship; at least three cables, each cable having opposing terminal ends hingedly connected respectively to each of the terminal posts, the at least three cables held in tension a distance above a grade of the ground and vertically spaced apart from one another in relation to the grade; and a line post secured in the ground and positioned between the pair of terminal posts, the line post holding a portion of each of the cables.

Abstract: An assembly for releasing tension in a cable includes a mounting plate holding the cable in tension, the mounting plate oriented substantially parallel to the cable when it is in tension; and a leveraging member having a base positioned between the mounting plate and the cable and a leg extending upward from the base relative to the ground surface, wherein the leveraging member leverages the cable from holding connection with the mounting plate when it is impacted with a sufficient force.

Abstract: A fence having at least two posts positioned in a spaced apart relationship to one another; a rail connected across the at least two posts, the rail having an interior defined by a periphery, the periphery having a pair of ends defining an opening into the interior, the ends being rolled into the interior; a panel having an edge portion, the edge portion positioned through the opening into the interior; and a lock member having a base and an opposing top side, a front end and a tail end, the top side forming a recess and having a tapered section sloping downward, relative to the base, from the recess to the front end, wherein the lock member is positioned in the opening with one of the ends disposed in the recess and the base positioned against the panel.

Abstract: A bollard, which is positioned in a structure having a grade level, includes an outer member having a first section extending above the grade level; an inner member having a filler material; and a connector operationally connecting the inner member and the outer member, wherein the inner member straddles the grade level and is rotatable relative to the outer member.

Abstract: A cable-release anchor assembly including a cable mounting plate adapted for removably holding a cable proximate its terminal end and a leveraging member positioned to release the cable from the terminal end when the leveraging member is impacted. The cable may be connected to a safety system such as, but not limited to, a cable barrier system, W-beam guardrail, and/or an energy absorption system.

Abstract: A releasable post-cable connection includes a post having a top end extending above a ground level. The post having an internal cavity and a slot formed through a post face wall extending downward from the top end of the post in communication with the cavity and a hairpin connector carrying at least one cable and releasably mounted to the post. The hairpin cable connector includes an elongated section forming at least one loop adapted for disposing a cable, and a top section extending at an angle from the elongated member. The elongated section is substantially disposed within the cavity and the loop extends exterior of the cavity, and the top section hung on the top end of the post. When the post is impacted and urged toward the ground level the cable is released from the post.

Abstract: An example of the cable barrier system includes a cable-release anchor assembly; a length of need section having a plurality of line post spaced from each other, each of the line posts having an internal cavity and a slot formed along a sidewall extending downward from a top end of the post; a cable having a terminal end that is releasably held in tension by the cable-release anchor assembly; and the cable releasably connected to each line post by a post-cable connector, the post-cable connector having an elongated portion forming a loop, the elongated portion disposed substantially within the cavity and the loop extending through the slot exterior of the cavity, the cable slidingly disposed in the loop, wherein when an object impacts and deforms one of the posts toward ground level the cable is released from the deformed post in a manner such that the cable tends to stay in contact with the impacting object.

Abstract: A method of releasably connecting a cable to a post in a manner such that the cable will release from the post when the post is deformed toward ground level, the method includes the steps of providing a post having an interior cavity and a slot formed through a post face wall extending from the top end of the post; disposing a cable within a loop formed in an elongated section of a connector; hanging the connector from the top end of the post, the elongated section positioned substantially within the cavity and the loop and the disposed cable positioned exterior of the cavity; and tensioning the cable.

Abstract: A cable barrier system including a cable-release anchor assembly, a terminal end section having at least one terminal post, the terminal post disposed adjacent to and spaced from the cable-release anchor assembly, and a length of need section having a plurality of line posts spaced from each other, each line post having an internal cavity and a slot formed along a sidewall extending downward from its top end. At least one cable having a terminal end is connected intention between the cable-release anchor assembly and the posts, the cable connected to the cable-release anchor proximate its terminal end. The cable is releasably connected to the terminal post and the line posts. The cable is releasably connected to the line posts by post-cable connectors. The post-cable connector includes an elongated section forming loops, the elongated portion is disposed substantially within the cavity and the loops extend through the slot to the exterior of the cavity. The cable is slidably disposed in the loop.
