1. A crane control system for actuating positioners of a crane, wherein the crane control system is configured to perform the following functions:
receiving target position data which describes a predefined target position of at least one positioner;
receiving clearance data which describes a user input for clearing a movement of the at least one positioner into the predefined target position;
outputting control data which describes control signals to be output to the at least one positioner in order to move the at least one positioner into the predefined target position, and
converting a control command input by a user activating an operating device into an actuation signal to actuate at least one additional positioner, such that the at least one additional positioner is controlled by the user via the operating device,
wherein the crane control system outputs the control data for as long as the user activates the operating device, such that the at least one positioner is automatically actuated by the crane control system to move according to the control signals in order to automatically move into the predefined target position, in parallel with the user controlling the at least one additional positioner by activating the operating device,
wherein the at least one a positioner is a telescopic cylinder, luffing cylinder or lifting mechanism, and the at least one additional positioner is another of the telescopic cylinder, luffing cylinder and lifting mechanism.
