Abstract
A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.
