Under Pressure

It’s important to understand that the principal concern related to the forces that wind exerts on a tower crane’s load is not the speed of the wind, but its pressure.

Tower cranes, by design, are able to withstand wind speeds up to 140 miles per hour, depending on the manufacturer; however, they must be allowed to “weather vane” to avoid wind pressure on the boom (side loading). The same applies to mobile cranes with long booms, especially if they are lifting and moving loads in very windy conditions.
