POWER TRANSFER DEVICE FOR A ROLLING DOOR OPERATOR
A power transfer device for a fire door operator having a pair of drive gears includes a bridge gear box having a drive shaft suitable for being coupled to an external drive. An idle spur gear is fixed to the drive shaft. A pair of spur gears are coupled to the idle spur gear to rotate in response to rotations of the idle spur gear. Spur gear shafts are coupled to the spur gears and arranged to be coupled to the drive gears of the operator so that rotation of the drive shaft by an external drive is translated to simultaneous rotations of the drive gears of the operator.
