ABSTRACT:
A lift gate has its bearing structure mounted on a post for rotation about a vertical axis to provide lifting and an alternative swing action. Mechanical latches normally keep the gate from swinging. An electrical motor normally lifts the gate and power is maintained by a solar electric panel. The motor can be mechanically disconnected from the gate to provide for manual lifting of the gate when there is a malfunction. A clock mechanism energizes the motor to close the gate after it has been opened for a predetermined time period.
