A vehicle crane system includes a vehicle crane with an attachment part, in particular a bracing device, which can be mounted on and removed from the telescopic jib of the vehicle crane, and to an attachment part transporting unit for transporting an attachment part of a telescopic jib of the vehicle crane. A mobile transporting device is provided for transporting the attachment part and has at least one loading arm, the free supporting end of which can be coupled to the attachment part carried or to be carried on the transporting device. The loading arm is arranged movably on the transporting device such that the attachment part can be moved between the transporting device and the telescopic jib. Furthermore, the transporting device has a tilting device which is designed for raising and lowering one side of the attachment part carried or to be carried on the transporting device.

A vehicle crane system includes a vehicle crane having a detachable attachment part, in particular a main jib, and an attachment part transporting unit which is designed to receive the attachment part when the latter is detached from the vehicle crane and comprises a mobile transporting device for transporting the attachment part. To remove and mount the attachment part of the vehicle crane and to transport it, the transporting device is equipped with at least one loading arm, the free supporting end of which is provided for at least indirect temporary coupling to an attachment part which is to be received or is already received. The loading arm is mounted pivotably on the transporting device such that an attachment part to be loaded or unloaded can be moved down onto the transporting device or from the transporting device.

A method of operating a mobile crane with a boom includes the steps of determining maximum permissible loads for a plurality of positions in a predetermined position range of the boom, determining a load limit and/or one or more load ranges based on a suspended load and on the maximum permissible loads for the plurality of positions of the predetermined position range of the boom, and operating the mobile crane dependent upon the load limit and/or the one or more load ranges. The load limit can be a local load limit and the one or more load ranges can be one or more local load ranges.
