Abstract
A control unit of the crane controls drives that move an upper load suspension point and, together therewith, a load suspended via a cable system. As the upper load suspension point is moved, an inner safety zone around the load is repeatedly dynamically determined according to state variables of the crane. The state variables include at least a position and a speed of movement of the upper load suspension point, and an effective pendulum length of the load. The control unit checks, based on further known information whether an object different from the load has entered the inner safety zone, in which case the movement of the upper load suspension point is stopped or a message to stop the movement is outputted to an operator of the crane. Otherwise, the movement is maintained or no message to stop the movement is outputted to the operator.
