The overhead gantry crane at Newport News, largest in North America, has a 900-ton capacity. Carriers are constructed as modules weighing less than that and lifted into place in the building dock.

Here's the video of the island lift for CVN-78, Gerald Ford, earlier this year:

As you may notice, the island is a completely new design from the Nimitz-class ships and sits farther aft.
