The present invention concerns a security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid. The invention further comprises a method of manufacturing such security barrier and a method of preparing the security barrier for providing protection in a public space.

A variety of systems, methods, and compositions are disclosed, including in one method, a security arm barrier system, the system comprising: a drive stanchion mounted to a first substructure; an arm barrier coupled to the drive stanchion, wherein the arm barrier further comprises: a first member, wherein a proximal end of the first member is coupled to the drive stanchion; a second member, wherein a proximal end of the second member coupled to a distal end of the first member; and an articulating joint that couples the first member and the second member, and an energy absorbing material disposed within the first member and the second member; and a receiver stanchion mounted to a second substructure capable of receiving a distal end of the second member.

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.

A force-absorbing barrier 10 includes a plurality of concentric chambers 21, 23, 25 and 27 at least partially filled with fluid 42. The walls 22, 24, 26 and 28 defining the chambers are flexible. Fluid passages 30 in the interior walls 24, 26 and 28 between chambers allow fluid flow between the chambers. The fluid flow from chamber to chamber will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.

A protective construction, such as a fence for a race track, may include a device for energy dissipation, e.g., in line with a guy wire. In some examples, the energy dissipation device may have a braking profile and a cutting unit having at least one blade that can be pulled through the braking profile along its longitudinal axis.

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.
