Gives a simplified method of calculation and assumes that the wind blows horizontal from any direction, that the wind blows at a constant velocity and that there is a static reaction to the loadings applying to the crane structure. Includes built-in allowances for the effects of gusting (rapid changes in wind velocity) and for dynamic response.
