A crane control system for actuating positioners of a crane is configured to receive target position data which describe a predefined target position of at least one positioner, in particular at least one crane superstructure positioner; receive clearance data which describe a user input for clearing a movement of the at least one positioner into the predefined target position; and output control data which describe 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.

A telescopic jib bracing unit for a mobile crane includes a holding frame which is embodied for fastening to the telescopic jib of the mobile crane and exhibits an open cross-section, the cross-sectional opening of which enables the jib to be retracted into the holding frame, and two bracing supports which are connected by the holding frame to form a structural unit. Two frame parts which form the open cross-section of the holding frame are coupled to each other via a coupling point such that they can be moved with respect to each other. A bracing unit transport system, a mobile crane and a fitting method are also provided.
