Scope

This document specifies the general calculation method for crane wind loads given in GB/T 22437.1-2018. The calculation of crane wind loads can be used for crane capacity verification, such as the capacity verification of crane metal structures specified in GB/T 30024.
This document provides simplified calculation methods for the following assumptions:
a) Any horizontal wind direction;
b) Constant wind speed;
c) A static reaction force will be generated on the crane structure by the applied wind loads.
This document includes built-in tolerances for gust effects (wind speed fluctuations) and dynamic responses.
This document provides guidelines for anchoring cranes in non-working states.
This document is applicable to the calculation of wind loads for cranes in both working and non-working states.
