A gate assembly including a support structure, a gate carried by the support structure and movable with respect thereto, a gate control and a gate activator associated with the gate, the support structure including a plurality of frame members, the gate having one end thereof disposed adjacent to the support structure and extending outwardly therefrom, a pivot connecting a lower part of the gate to an adjacent lower portion of the support structure, the pivot including a rotatable shaft and shaft carrier, the gate control including a biasing mechanism associated with the gate, the gate activator including a power source mounted on the support structure, drive mechanism operatively connected to the power source, the drive mechanism including translating mechanism activatable by the power source, the translating mechanism being disposed for movement in a substantially horizontal plane, an arm member having one end pivotally connected to the translating mechanism, the arm member having its opposite end pivotally connected to the gate, the connection between the arm member and the gate being at a point on the gate adjacent the support structure and centrally located between the upper and lower edges of the gate, whereby the gate is movable about the pivot in a vertical plane by the gate activator.
