END TREATMENTS AND TRANSITIONS FOR WATER-BALLASTED PROTECTION BARRIER ARRAYS
20180127933 · 2018-05-10 ·

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

Guard cable for road

A guard cable for a road, includes a plurality of wire ropes extending in a horizontal direction with respect to a plurality of supports provided on the side of the road at intervals. The wire ropes are shifted to a predetermined width from the supports to the roadway by a wire rope protrusion installation unit. The plurality of wire ropes provided between the supports are maintained at constant intervals by an interval maintenance plate.

Safety Trailer

The present invention is directed to differing embodiments of safety trailers, which have first and second platforms and a safety wall positioned therebetween. The platforms and safety wall define an area protected from vehicular incursions.

Vehicle catch systems and methods

Vehicle restraints and fence systems that offer better protection to the driver and vehicle in the event of an accident where the car becomes airborne and leaves the road or track, and catch fences for halting the overrun of a car leaving a racetrack. The catch fences may have pivotable poles and a cable extending between the poles. Net or fencing is installed between the poles, supported by the cable. The poles may be angled or curved, with a plurality of cables extending therebetween or with a net extending from the poles and attached to a Steel and Foam Energy Reduction barrier.

20170081815 · 2017-03-23 ·

A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

Shape Recoverable And Reusable Energy Absorbing Structures, Systems And Methods For Manufacture Thereof

An energy absorbing cell has a first structural element, a second structural element disposed parallel to and spaced apart from a first structural element, a first intermediate member, and a second intermediate member. Each intermediate member is disposed at an angle between the structural elements. A first end and a second end of each intermediate member are respectively attached to the structural elements. The intermediate members are formed from an elastic material. The angles of the intermediate members are selected such that application of a compressive force to displace the structural elements toward one another triggers a snap-through instability in both intermediate members. The energy absorbing cell is used, singly or in combination with one or more other energy absorbing cells, to form energy absorbing structures, such as vehicle bumpers or highway barriers, adapted to control the deceleration of an object impacting the energy absorbing structure.
