ABSTRACT:
An electric swinging gate assembly comprises a gate section hingably mounted onto a vertical post of the fence. An electric motor having a horizontal drive shaft is mounted onto the gate section, wherein a first pulley member is mounted on the free end of the horizontal drive shaft. A second pulley member and a large wheel are mounted on a horizontal axle rod, wherein the ends of the rod are rotatably contained in bearing assembly mounted on the bottom ends of vertical bars of the gate section. The large wheel engages the ground such that the electric motor causes the wheel to rotate, wherein the gate section can be swung open or closed. Alternatively, an end vertical rod of the gate section can be rotatably mounted in bearing assemblies communicating with the vertical end post of the fence. An electrical motor having a vertical drive shaft is mounted on the fence. A first pulley is contained on the vertical drive shaft and a second pulley is contained on the upper end of the end vertical rod, wherein a pulley belt communicates between the first and second pulley.
