  • Patent number: 8985891
    Abstract: A road safety barrier having a plurality of ropes supported by posts rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and supported in a notch or groove in a side of the posts. The ropes are released from a post and the post is not pulled from the ground when a vertical force is exerted on the rope. The ropes when weaved are tensioned against the posts and this gives use to a combined frictional resistance to displacement of the ropes relative to each post along the length of the safety barrier. The structure of at least some of the posts and/or their mounting with respect to the ground defines a minimum bending yield strength in a direction along the length of the barrier. This minimum bending yield strength is greater than the bending moment resulting from the combined frictional resistance forces acting on the post.

  • Publication number: 20140110652
    Abstract: A frangible post captures and holds a cable anchor to a guardrail. The post breaks when struck by a vehicle, releasing the cable. The frangible post may include hinge members, which bias the post so that weakened sections are put in tension when the post is struck, thereby ensuring that the post breaks cleanly and the cable is released when the post is struck. A method of releasing a cable anchor includes impacting the post, biasing the weakened sections so that they are in tension, breaking the post, and releasing the cable anchor. The post may be configured with a notch to engage the cable anchor, which is then released from the notch as the post is broken.

  • Patent number: 8678701
    Abstract: The system for remote control of retractable, ground-based vehicle barriers increases control of the emergency lane of the road by mounting ground signboards in the emergency lane to prevent any vehicle to pass through this lane and so the police vehicle or the ambulance can easily and quickly approach the site of accident through the emergency lane. The signboards include a U-shaped frame permanently mounted in the emergency lane and a panel pivotally attached to the frame. Servo motors are provided to rotate the panels between a vertical position providing a barrier to traffic and a horizontal position permitting an emergency response vehicle to travel through the emergency lane. The emergency response vehicle is provided with a remote control unit having a short-range transmitter that transmits a trigger signal that is received by a unit at the barrier sign to activate a motor controller to lower the sign.

  • Patent number: 8596617
    Abstract: A guardrail includes a cable routing device providing a tortuous path for at least one tensioned cable, the cable routing device includes a bar having a rotational axis and including a cable entry port having a circumference slightly larger than the cable which passes directly therethrough when the bar is in a first non-cable gripping orientation in which the diameter of the port (diametric width) is substantially orthogonal to the longitudinal axis of the cable, and wherein rotation of the bar about the axis effectively decreases the width of the port relative to the width of the cable to create a second cable-gripping orientation which provides the tortuous path, wherein the tortuous path through the bar is due to the relative decrease in the effective diametric width of the port and this provides sufficient frictional resistance to movement in relation to the cable during impact to facilitate impact energy dissipation.
