ABSTRACT:
A gate opening apparatus which utilizes a horizontably swingable arm assembly which is to be operated electrically to effect movement of a gate between a closed position and an open position. The arm assembly is mounted through a latching mechanism to the motor mechanism of the gate opening apparatus. This latching mechanism can be manually released which will permit the arm assembly to pivot through a vertical plane so as to provide for manual movement of the gate between the open and closed position during instances when electrical power is not available to operate the gate opening apparatus.
