A road safety barrier installation system that uses a workstation and product support able to be guided by a truck along a road. The product supporter is adapted to receive a store of product such as ground penetrating anchors, posts and barrier strap. The workstation comprises at least one placement robot able robot able to receive and hold a said product, and position the so received and held product in location as part of the array.

Disclosed is a shock absorber for buffering the barrier wall of a road. According to the present invention, a horizontal inner pipe bumper is inserted into a pedestal attached to a boundary of a barrier wall and joined to the support pillar. The buffer rail transversely connected to the protruding portion of the buffer pad on the front surface of the pedestal constitutes the buffer portion of the collision portion barrier wall, and when the buffer pad adhered to the inner pipe bumper is displaced upright, tension of the elastic rail connecting the buffer pad and the elastic rail block is generated, and the guard rail of the pillar is coupled to the barrier bridging body by a connecting member.

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.

A barrier system is provided including a plurality of barrier members arranged in an end to end manner to form an elongate barrier structure. A first end barrier member is located at a first end of the elongate barrier structure and a second end barrier member is located at a second end of the elongate barrier structure. Each of the first and second end barrier members have base anchor means provided or associated with at least an outermost end thereof to anchor a base of the first and second end barrier members to a surface on which the barrier system is to be located in use. A pair of barrier members consisting of two adjacent barrier members, which are not the first and second end barrier members but which are adjacent to each of the same, are provided with channel means located on, at or adjacent at a top thereof.

This invention relates to a plastic guardrail, extruded into a structure having multiple layers and ribs between the layers using a thermoplastic resin, and configured such that an outer layer using a material having high strength to increase impact resistance, and an inner layer and the ribs using a material having lower strength than that of at least the outer layer to increase an internal cushioning effect are integrated with each other through a double extrusion process. The guardrail of the invention can exhibit both impact resistance and a cushioning function.

A system and method for installing or altering a guardrail section on site is provided, as is a method for installing or altering guardrail sections on site. The system comprises a punch press comprising a throat for receiving a guardrail section therein comprising a punch suitable for punching a hole through the guardrail section and a die capable of receiving the punch after passage through the guardrail section. An articulating arm is attached to the punch press and a mobile device is attached to the articulating arm wherein the mobile device is capable of manipulating the articulating arm to place the punch press in engaging relationship with the guardrail section.
