Abrégé

Crash attenuator guardrail apparatus includes an impact head and a backstop having a cable and guardrails supported by guardrail supports located between the impact head and the backstop. Frictional forces are applied to the cable to control and resist movement of the impact head toward the backstop and provide lateral resistance. The guardrail supports include a base having break away structure and brace members having bends and which shorten or lengthen to absorb energy resulting from vehicle impact.

Abrégé

A trailer crash attenuation assembly includes a longitudinal hollow member adapted to act as a hydraulic cylinder at one end, hydraulic fluid disposed in the hydraulic cylinder and a tank connected to the hydraulic cylinder to receive and store said hydraulic fluid expressed from the hydraulic cylinder. A first longitudinal telescopic member is adapted to slide into and out of the longitudinal hollow member and is adapted to act a piston. Two other longitudinal hollow members are positioned substantially parallel to and on either side of the first longitudinal hollow member and are connected to the first longitudinal hollow member. Two telescopic members are adapted to slide into and out of the two other longitudinal hollow members respectively. A casing is connected at its proximal end to all three longitudinal hollow members, is adapted at its distal end to receive a crash cushion; and has a pair of wheels.

Abrégé

A system for repositioning an elongated traffic barrier utilizes a tow vehicle connected to one end of the elongated traffic barrier to exert a pulling force on the elongated traffic barrier and a drag connected at the other end of the elongated traffic barrier to exert a drag force opposed to the pulling force exerted by the tow vehicle to resist wandering of the elongated traffic barrier during repositioning thereof.
