Wind Loads on Crane Support Structure

Wind Loads on Crane Support Structure

Wind Loads on Crane Support Structure

(OP)
Dear Forum Members,

I need clarity on the recommendations of Eurocode EN 1991-3 (2006) regarding wind loads on cranes outside and inside buildings.

Point 6 of Annex A recommends a wind speed of 20 m/s for crane operation compatibility. I assume that the crane operation will shut down when the speed exceeds 20 m/s. I also assume that this wind speed restriction is for cranes outside the building.

The code does not mention any wind speed restriction for cranes inside buildings (Point 7 of Annex A). Does it mean that the crane opearation is not affected, when a building is subjected to a much higher wind speed (say 40 m/s), irrespective of increased lateral deflection of the frames of the buildings that support the crane?

Or is it the crane manufacturers responsibility to include wind speed restrictions in operation manual for cranes inside buildings?

Best Regards,

StructuralNomad
