There's a construction project going on next to my office. They recently
used a big yellow moveable crane to construct a fixed tower crane, picture

What's the advantage of the fixed tower crane over the moveable one?

Better power to weight ratio seems the chief benefit, and might mean
lower operating costs as well.
