K-10000 tower crane
THE SHORT STORY:
THE LONG STORY:
Tower cranes, in the capacity range normally encountered, and at maximum
free standing height, develop their maximum Design Base Moment not in
service due to Hook Load, but rather out of service due to Design Wind
Load, typically 100 M.P.H.
In the K-10000 tower crane, the Moment due to Hook Load is all dominating, while the Moment due to Wind is insignificant. Consequently, the moment in the tower is virtually the same from Top to Base.
a tower crane rotates at the top, as almost all do, and when the Jibs are diagonal to the
Tower, there is only one Mast Corner Leg to carry the Compressive
Load due to Moments.
