Note: These mast combinations meet the EN 14439 and ASME B30.3-2012
specifications for“out of service” wind conditions, provided the illus-
trated 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 37-02, with the assumption that this crane
is considered a temporary structure used during a construction period of
2 years or less.
