ABSTRACT:
A gate spanning a roadway presents an effective barrier to cattle and other livestock but tilts open in either direction of the roadway from closed, upright position to a horizontal position supported on the roadway surface under the force exerted by a motor vehicle nudged against the gate and driven over the gate in its horizontal position.
Counterweights connected to the gate by tension lines exert a restoring force urging the gate into upright position. The counterweights operate at an elevation well out of the way of people and vehicles and are provided with backup safety tether lines to prevent any harm in the unlikely event of failure of the tension lines.
