According to particular embodiments, a door operating system comprises: a rotating handle removably coupled to a first gear; the first gear coupled to a second gear; the second gear removably coupled to a worm gear; and the worm gear coupled to a rotating plate. Rotation of the handle rotates the first gear which rotates the second gear which rotates the worm gear which rotates the rotating plate to cause the door to open or close. The first gear is swappable with the second gear to modify a gear ratio of the door operating system.
