Abstract (en)
[origin: WO2017081019A1] The invention relates to a mobile crane having a main jib (2) that is mounted thereupon for luffing and that can be oriented by means of a luffing cylinder (7), and a main jib extension (1) which is detachably connected to a main jib head (2a) of said main jib (2) by means of upper and lower bolts (4c), it being possible to angle said main jib extension (1) about a luffing axis (w) relative to the main jib (1) proceeding from a base position following release of the upper or lower bolts (4c) and using an angle drive (6j), said angle drive engaging with a foot (1c) of the main jib extension (1), a maximum angling angle (b) being delimited by an adjustable angling plate (5), and said angling plate (5) engaging with the foot (1c) of the main jib extension (1) and the main jib head (2a). In order to obtain a mobile crane which simplifies angling of the main jib extension, it is suggested that the angle drive (6j) is a component of an angling plate (5) in the form of a combi-angling plate (6). The invention also relates to a method for angling this main jib extension.
