摘要： 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.

摘要： The invention relates to a mobile crane having a main jib (1), which is mounted tiltably thereon and can be erected by means of a tilting cylinder (3), and having a main jib extension (4) which is connected releasably to a main jib head (1a) of the main jib (1) by means of upper bolts (7) and lower bolts, wherein, starting from a normal position, after release of the upper bolts (7), the main jib extension (4) can be angled about a tilting axis (W) relative to the main jib (1) by means of an angling drive, and the angling drive engages on a foot (4d) of the main jib extension (4), wherein a drive of the mobile crane, which is provided for another purpose, supplies the kinetic energy for the angling drive. In order to simplify bending of the main jib extension, according to the invention, the angling drive comprises a lever element (5) having two lever arms (5a, 5b), wherein the lever element (5) is mounted pivotably on the upper chord (4a) of the main jib extension (4), the first lever arm (5a) is connected to a lifting cable (11) of the lifting gear (14) for the operation of the angling drive and engages on the main jib head (1a) by means of the second lever arm (5b).

摘要： The invention relates to a mobile crane, comprising a main boom (1), which is supported on the mobile crane in such a way that the main boom can be rocked and which can be put upright by means of an elevating cylinder (3), and a main boom extension (4), which is releasably connected to a main boom head (1a) of the main boom (1) by means of upper pins (6) and lower pins (7), wherein main boom extension (4), proceeding from a home position, can be angled in relation to the main boom (1) about a rocking axis (W) by means of an angle drive after the upper pins (6) have been released, which angle drive acts on a base (4d) of the main boom extension (4), wherein a drive of the mobile crane provided for a different task provides the kinetic energy for the angle drive. In order to simplify angling of the main boom extension, the angle drive according to the invention is designed in such a way that a telescoping cylinder of the main boom (1) provides the kinetic energy for the angle drive. The invention further relates to a method for angling a main boom extension therefor.
