Two cranes on site today. One small one that i saw the other day, and one big one, almost the full height of KA. It looked to be about as high as zumanjaro appears it will be. Didn't notice any activity or parts moving while i was there. I did attempt to take some photos but it was on my iPhone so bare with the quality, I'm uploading them now and will try to edit them somehow to point out the cranes.
Edit- here are the photos
