ABSTRACT:
A drive mechanism for an industrial door. A rotatable drive member is operably connected to the door and rotation of the drive member in one direction through operation of a motor will move the door to the closed position while rotation of the member in the opposite direction will move the door to the open position. A clutch mechanism interconnects the motor and the drive member and is movable between an engaged and disengaged position. The clutch mechanism is biased to the engaged position, and by manually pivoting an actuating member that is connected to the clutch mechanism, the clutch mechanism can be moved to the disengaged position, and is retained in the disengaged position until manually released. A switch is operably connected to the motor, and when the actuating member is pivoted to a position to disengage the clutch, the switch will be actuated to shut off power to the motor.
