These mast combinations meet the EN 14439 and ASME B30.3-2012 specifications for "out of service” wind conditions, provided the illustrated wind speed matches required design wind for the location of the tower crane. The "out of service” design wind speed was determined in accordance with ASCE 7-10, Figure 26.5-A. The wind velocity, used for this configuration was 98 mph (158 kph), which represents a nominal design 3-second wind gust at 33 ft (10 m) above ground for Exposure B category A. Factor of 0.85 was applied to the 50-year ultimate design wind speed of 115 mph (185 kph), per ASCE...
