There's two tower cranes installed for 1WTC but they can't lift 60-70 ton beams that's used on the base of this building. So that's why there's two mobile cranes helping out until the base section steel is installed.
In addition, there will be one more tower crane installed that will be attached to the side of the building once steel rises high enough and requires a need for it.
That's 5 cranes, biggest and the best out there. Quit being picky on how it's done.
