Abstract

The telescopic jib comprises a telescopic section extending from an articulated section, and two bracing supports (5) pivot-mounted on one of the sections. Each of the bracing supports is pivotable around only one single respective pivot point (4) inclined in such a way that the supports spread out in V-form during orientation into the operating position. The pivot axes lie in a diameter plane (9) of the articulated section and in relation to the longitudinal center plane of the jib include an angle comprising the spread angle of the supports to the vertical longitudinal plane in their operating position plus 90 degrees.
