Abstract
The invention relates to a mobile crane comprising a telescopic jib (1) that can be telescopically extended by means of a drive located on the inside, has a basic box section (6) that is connected via a rotary joint (2) to the superstructure (7) of the mobile crane (10) and has one or more sections (inner box sections 3, 4, 5) that can be extended and retracted telescopically and, by means of a tilting cylinder (8), can be erected from a substantially horizontal position for the transport into a working position, the telescopic jig (1), when retracted telescopically, being longer than the length of the chassis L.sub.F and at least substantial telescopic parts of the telescopic jib (1), when retracted telescopically, being displaceable rearward in the substantially horizontal position with respect to the superstructure (7). The invention achieves the object, while maintaining the greatest possible length that can be extended telescopically from the telescopic jib, and without the necessary to release the rotary bearing on the base box frame of not permitting the overhang of the telescopic jib with respect to the chassis of the mobile crane to exceed the permissible dimension in the transport position and keeping the expenditure on construction for this purpose as low as possible.
