Abstract: The present invention relates to posts, carriages, methods of manufacturing the components and their assembly into a barrier. The invention also includes a Z post attachment includes an attachment tab 8.016 and end engagement flange 8.024, 8.026 adapted to engage the end of the post. The arrangement can include a delineator 8.030 which is skew in relation to the tab 8.016, so as to provide reflector faces 8.032 which face oncoming traffic.

Abstract: A roadway barrier or guard rail system includes a post (12) that passes through the carriage (20) with the carriage (20) being free to move up along the post (12) to dissipate energy during a collision. The carriage (20) is prevented from moving down the post (12) by a stop or restraint (12.60,12.50,12.40,12.30), which is separate from and underneath the carriage (20) and which the carriage (20) abuts, with the stop or restraint (12.60,12.50,12.40,12.30) being located on the post (12).

Abstract: A post assembly for absorbing impact from a vehicle including a footing, an upright post and a hinge region to allow the post to plastically deform relative to the footing. The post is preferably fixed to a lever arm that is connected to the footing via the hinge region, the lever arm and post pivoting away from the footing under load, The lever arm, footing and hinge region are preferably formed from a common base plate. The invention also relates to barrier system that includes multiple post assemblies, and a barrier supported between respective posts of the assemblies.

Abstract: The present invention provides a roadway barrier or guard rail system which has a post (12) which passes through the carriage (20) with the carriage (20) being free to move up along the post (12). The carriage (20) is prevented from moving down the post (12) by means of a stop or restraint (12.60,12.50,12.40,12.30) which is separate from and underneath the carriage (20) and which the carriage (20) abuts, with the stop or restraint (12.60,12.50,12.40,12.30) being located on the post (12). The carriage (20) is not otherwise restrained from moving up the post except by the curved channels through the carriage (20) which engage the extremities of the post, and the friction this may produce.
