In a telescopic jib, for example for inclined hoists or the like, with a multiplicity of telescopic sections which are guided on one another and are displaceable relative to one another via a rope pulley system and the last telescopic section of which is subdivided in an articulated manner, where the angular position of the parts relative to one another and thus the inclination angle alpha can be fixed, the last telescopic section, which can be disposed at an angle, is to be fully retractable into the penultimate telescopic section, and any angular position is to be selectable from the operating platform. In order to achieve this, the penultimate telescopic section is provided at its outer end with a guide portion attached in an articulated manner, and the last telescopic section has a corresponding articulated portion at its inner end.
