The invention relates to a method for monitoring the operation of a crane, in which an overall center of gravity of the crane, possibly with a load attached thereto, is determined and monitored in terms of its position in relation to a tipping edge of the crane, wherein possible displacements of the overall center of gravity caused by possible changes in different operating and/or influencing variables, which comprise at least different crane movements, and resultant future overall centers of gravity are determined, wherein the most critical overall center of gravity in relation to the tipping edge is determined from the determined plurality of future overall centers of gravity and a possible restriction of crane movements is determined on the basis of the position of this most critical future overall center of gravity in relation to the tipping edge.
