Abstract (en)
The jib has a cable (4) guided over a device located on the base body (G) and adjustable in its angular position after the fashion of a tensioning frame. The jib, via the cable, can telescope in or be tensioned, and upon demand the tensioning device can be pivoted from a neutral position to a working position. The cable is guided externally along the jib. The tensioning device comprises a pivoting rod (2) with a roller (3) over which the cable passes, and a piston and cylinder unit (6) by which the rod is movable into its desired angular position.
