You have to keep turning the handle while keeping the ball in the center area for what seems like forever. Just keep turning. Then you will hear a sound like metal moving or something being pushed. Nancy will say something like "What's that sound...I wonder if it has to do with the walkway"
Now you can get to the communications room from the catwalk.
Hope this helps.
