How does an engineer figure out what the safe maximum wind speed is for a construction crane?

Recently a large Crane fell in Tampa and caused a lot of damage. I heard people say it was “rated” for wind speeds that were less than the wind speeds of the recent hurricane. How can it be measured down to certain winds speed, as in, 100 MPH is safe, but 130 MPH is not safe?
