Ehdotuksen tiedot

This International Standard specifies the assessment of wind loads on cranes. It establishes general methods for calculating wind loads (for in-service and out-of-service conditions), which are included in the load combinations stated in ISO 8686 series and used for proofs of competence such as those given in ISO 20332 for the structural components of cranes. It provides a simplified method of calculation and assumes that — the wind may blow horizontally from any direction, — the wind blows at a constant speed, — there is a static reaction to the wind load applied to the crane structure. It includes built-in allowances for the effects of gusting (fluctuation in wind speed) and for dynamic response. It gives guidance on when to secure the crane for out-of-service conditions.
