Abstract: A post is provided which includes apertures on alternate sides of the post which, in use, receive and retain at least one cable therein, the same number of apertures are on each side of the post wherein each aperture: has a side opening in the form of a mouth, wherein the mouth is at a distal region thereof configured to have a top surface with an angle greater than the angle at a proximate region of the mouth so as to reduce the travel path of, and/or; any frictional contact with; the cable, during ejection from aperture following a collision.

Abstract: A method of absorbing energy from a moving object upon impact, where the method includes utilizing at least two types of energy absorbing elements to absorb at least some of the energy of the impact in an energy absorbing apparatus. A first type of energy absorbing element absorbs the majority of the energy absorbed by the apparatus and subsequent types of energy absorbing elements continue to absorb energy after the first type of energy absorbing element has ceased operation and can no longer absorb energy.

Abstract: A cable-barrier system that includes an anchor-body and terminal post which receive and retain one or more anchor-cables and are anchored to a footing to counter balance the force applied to the anchor body by one or more barrier-cables. The system also allows for the release of the anchor-cables during a collision by a vehicle.

Abstract: An energy absorbing apparatus is provided and includes an outer shell having opposed ends, left and right side walls and a hollow core. The shell further includes a plurality of longitudinally spaced apart fold points positioned on the left and right side walls at a height which substantially corresponds to a center of gravity of a road vehicle where the fold points facilitate a controlled folding of the side walls and at least part of the shell, at or around, the fold points, during an end on impact.

Abstract: 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.

Abstract: A slider assembly including a front section, and a back section, where the front section is adapted to conform to the cross sectional profile of rails forming the terminal end of a guardrail, or other barrier, to which the slider assembly will be fitted in use. The front section in combination with the back section create an internal space therebetween capable of substantially surrounding both an associated first rail and an associated second rail of the terminal end, and at least two further rails located downstream of the first and second rail. The slider assembly includes first and second opposed portions configured to move with respect to each other so the slider assembly can, in use, apply an increasing compressive force to telescoping rails as a consequence of the slider assembly travelling along one or more subsequent rail(s) during telescoping.

Abstract: A terminal post for a cable barrier which is of a unitary post construction. The integrally formed post has a cable barrier portion for retaining barrier cable(s) and an anchor-cable portion for retaining anchor cable(s). The cable barrier includes at least one cable-barrier portion which, in use, receives and retains one or more barrier-cables used in the cable barrier and at least one anchor-cable portion in the form of a central groove, which, in use, receives and retains one or more anchor-cables which are anchored so as to counter balance the force applied to the terminal post by the barrier-cable(s). The cable-barrier portion(s) and the anchor-barrier portion(s) within the post body are configured so that, in use, at least one of the anchor-cable(s) and barrier-cable(s) are releasable from the body during a collision with a vehicle where the anchor-cables act as a ramp and/or snag during the collision.

Abstract: A terminal post for a barrier includes an upright portion having an aperture positioned, so that in use: the aperture is located in a region of the upright portion above a ground engaging portion of the upright portion; and wherein located on one side of the aperture is a transverse reinforcing member which includes a slot for receiving a cable. At least one groove, or pair of notches is provided located beneath the aperture, and form(s) a predetermined fail line, along which the post will deform, upon receiving a substantially inline impact, which causes the transverse member to move to release the cable, and wherein the aperture is dimensioned to allow the terminal end of the cable formally retained by the slot to pass therethrough.

Abstract: A guardrail or other energy absorbing apparatus includes a plurality of terminal end rails extending longitudinally extend between a plurality of support posts, wherein a first four of said plurality of rails (labelled 1-4 below) situated at a terminal end of a guardrail, or impact end of an energy absorbing apparatus; are connected to one another at respective downstream and upstream ends via: an impact slider assembly joined to a downstream portion of terminal rail 1, and surrounding a downstream portion of terminal rail 1 and an upstream portion of an adjacent rail 2; a first set of frangible bolts which are the sole bolts connecting rail 2 and adjacent rail 3 together; and a second set of frangible bolts which connect rail 3 and adjacent rail 4 together, wherein at least one standard post bolt connects the rails 3 and 4 to a post at this joint.

Abstract: A method of producing a frangible post includes the step of forming a region of weakness by compressing a portion of at least one surface and/or edge of the post.

Abstract: A barrier is provided, including opposed longitudinal side members separated by a gap, supports which hold the side members above the ground; and at least one U-shaped member when viewed in transverse cross section which is/are connected to the opposed members to span between the gap and wherein the at least one U-shaped member does not contact the supports.

Abstract: A cable-barrier system that includes an anchor-body and terminal post which receive and retain one or more anchor-cables and are anchored to counter balance the force applied to the anchor body by one or more barrier-cables. The system also allows for the release of the anchor-cables during a collision with a vehicle.

Abstract: A temporary plastic barrier section includes a plastic shell having first and second plastic connection portions integrally formed on opposite ends thereof; and a rigid straight elongate member, wherein the rigid straight elongate member lies substantially adjacent to at least a portion of each of the first and second connection portions, and wherein the rigid straight elongate member includes connection points at the distal ends thereof which are configured to align substantially with the first and second connection portions.

Abstract: A barrier section which includes at least one connecting assembly at one or both ends of the barrier section, the connecting assembly having: at least one connecting-region which is positioned to be capable of engaging, or being engaged, with at least one connecting-region on an adjacent barrier section, in use; and the at least one connecting-region is configured to selectively engage with at least one connecting-region on an adjacent barrier section via at least one connecting device so the barrier sections have a fixed or pivotable relationship, with one another.
