Abstract: 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.

Abstract: A jib system for a vehicle crane having a telescopic jib and a bracing apparatus that can be coupled to the jib by its base frame, where the jib has a roller head and a lifting cable that is deflected via the roller head. Only minor structural measures and preparations are required for automatically rigging and de-rigging the vehicle crane, including by providing at least one transfer rocker that can be integrated in an articulated manner between the jib and the bracing apparatus. By the pivotable support of the transfer rocker on the jib, the base frame configured for coupling to the lifting cable can be displaced by a change in the length of the lifting cable that is effected in the coupled state on a circular path around its roller head from a set-down position of the bracing apparatus to a set-up position of the bracing apparatus and back.

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.

Abstract: In conventional vehicle cranes it is usually necessary in consideration of current safety regulations to provide at least two separate steering circuits for all steered axles so that, in the event of a failure of one circuit, the vehicle crane can continue to be steered by way of the other. In order to avoid that in accordance with the invention at least one steered rear axle of a vehicle crane (1) is provided with a caster (a) so that at least one axle (11-16), in the event of a steering failure, remains steerable passively by utilizing the caster friction. That principle is applied in a similar manner to a module axle (2) which can be mounted to the vehicle crane (1) and which can be required for transporting additional equipment or an additional counterweight which is possibly required.
