A telescopic jib includes a main box, at least one inner box and at least one swing-out mast. The mast is arranged on the inner box such that the inner box is able to be pushed into the main box together with the mast in a swung-in or folded-in position to thereby provide a telescopic jib that more easily provides an increased load-bearing capacity. In a particular configuration such a telescopic jib is disposed on a vehicle crane having wheels, axles, a lower carriage and a superstructure, with the telescopic jib mounted to the superstructure.
