Abstract

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.
