A mobile telescopic crane has a telescopic jib with at least three part-jibs. Each of the part-jibs is constructed from at least two part-jib portions so as to be telescopic in a longitudinal direction. Part-jib portions arranged at a spacing from one another transverse to the longitudinal direction each form a jib portion with at least one flexurally rigid connecting element. Respective adjacent jib portions are mechanically lockable with respect to one another in the longitudinal direction. A construction of this type of the jib means that an increase in the bearing load is easily achieved by increasing the area moment of inertia of the jib.
