Method for ascertaining the load capacity of a crane and crane

A method for ascertaining the load capacity of a functional element of a crane, the load capacity of a sub-assembly of a crane or the load capacity of a crane, wherein: a maximum bearing load is calculated for a specifically occurring configuration and/or specifically occurring state parameters and/or specifically occurring operating parameters on the basis of a predetermined formula; and the calculation is verified on the basis of stored bearing load values. 种用于确定起重机的功能元件的负载能力、起重机的子组件的负载能力，或者起重机的负载能力的方法，其中：对于特定发生的配置和/或特定发生的状态参数和/或特定发生的运行参数，基于预定公式计算最大承载负荷；以及基于存储的承载负荷值验证所述计算。
