Abstract
The present disclosure relates to a method of operating a crane whose safe working load depends on one or more changeable parameters, with the change of at least one of the parameters being made such that the speed of the parameter change is reduced continuously or step-wise before a parameter value is reached at which the safe working load corresponds to the actual working load.
