ABSTRACT:
A swinging gate is operated in one direction between open and closed positions by a winch and cable system driven by an electric motor which may be controlled remotely by radio, the winch and motor being carried on a support arm extending from a gatepost on one side of the gate. The gate is operated in the other direction by a falling weight connected to the gate by a cable extending around a pulley on a second support arm extending from the gatepost. The weight is raised when the gate is moved in the one direction by the winch and cable system and is held in raised position by the winch and cable while the gate remains in one of the open and closed positions. When the gate is to be moved in the other direction, the winch is released and the weight is allowed to fall. In a modification of the invention, the winch and cable system and weight are replaced by a reversible electrically operated linear actuator connected between the gate and a support arm extending from the gatepost.
