Heavy lifting cranes have always been interesting to me. It doesn't surprise me that there exists cranes that large but I always wonder what they are used for regularly; IOW, when a large jet doesn't need to be plucked out of a hole.
When I think of what a boom crane like that must cost, it would have to be used pretty regularly to even come close to amortizing for someone. As I was typing this, it occurred to me that it's probably borrowed from their nearest large port or harbor. I've never noticed a boom crane that large on a construction site.
