ABSTRACT:
The present invention relates to a gate closing device which operates either in an automatic mode or a manual mode. The device includes a first track which is adapted to be secured to a gate, and a second track to which a driving motor is interconnected. A linkage is slidably interconnected to both of these tracks. Activation of the motor results in the movement of the linkage, and thus the opening or closing of the gate. A damping device is employed at the first end of the linkage. The damping device enables the gate to be opened a slight distance without activating the motor.
