Claim 9:
10. A vertical pivoting gate operator for positioning a gate between an open position and a closed position, the gate operator comprising:
a gate arm shaft for positioning a gate between open and closed positions;
a gate arm secured to the gate arm shaft, the gate arm configured to support the gate thereon and position the gate between the open and closed positions;
a motor having an output;
a linkage assembly comprising a first segment mechanically coupled to an output shaft and a second segment mechanically coupled to the gate arm such that in response to actuation of the motor, the first segment and the second segment transmit an opening force from the output shaft to the gate arm for positioning the gate toward the open position, and transmit a closing force from the output shaft to the gate arm for positioning the gate toward the closed position;
a biasing member, the biasing member operable to exert a force on the gate arm shaft, wherein when the gate is in the closed position, the biasing member urges the gate arm shaft to rotate the gate toward the open position; and
a speed reduction assembly coupled to the output of the motor, the speed reduction assembly comprising a chain and sprocket or belt and pulley assembly.
