A vehicle frame and a mobile crane having such a vehicle frame includes a first frame part and a second frame part which can be detachably connected to each other via a common interface. The interface includes multiple points at which it is bolted to bolting elements assigned to the respective frame parts. The interface also includes at least one profile along which it engages with engaging elements assigned to the respective frame parts which, when the bolting elements are aligned with each other, are in a mutually positive-fit engagement across their extent.

A crane jib system having a main jib, an auxiliary jib, and a telescoping cylinder. The main jib is comprised of main telescoping portions and the auxiliary jib is attached to the main jib and comprises auxiliary telescoping portions. The telescoping cylinder has a first telescopic part locking unit disposed on a base portion of the telescoping cylinder. The first telescopic locking unit is adapted to selectively engage the main telescoping portions. A second telescopic part locking unit is disposed on the telescoping cylinder above the first telescopic part locking unit. The second telescopic part locking unit is adapted to selectively engage the auxiliary telescoping portions.
