The present disclosure relates to a method for determining the admissible load capacity of a crane, in which the load capacity is determined in dependence on at least one first and one second parameter and which comprises a first step, in which the load capacity for the value of the first parameter with different values of the second parameter is determined by calculation or by interpolation or extrapolation on the basis of known values of the load capacity with specific values of the first parameter, and which comprises a second step, in which the determination of the load capacity for the second parameter is performed on the basis of the values of the load capacity determined in the first step for different values of the second parameter by calculation or by interpolation or extrapolation.
