Abstract (en)
Telescopically extendable sections (2) of a telescopic jib of a mobile crane are guided on at least one sliding member (3), positioned on at least one extendable section so that it can be moved relatively to arrest the section in a fixed position with respect to a section (1) surrounding it. Preferably, two, three or four sliding members are provided, each shiftable longitudinally and/or axially relative to the jib. The thickness of the sliding member preferably increases downwards of the jib to form an inclined surface area. Guides (9) inclined at a predetermined angle may be provided for the sliding member on the section (2), configured so that the angle of inclination corresponds to the side of the sliding member facing it.
