摘要： A crane, particularly a railway crane, with a superstructure which is arranged on an undercarriage so as to be swivelable around a vertical axis, a jib and at least one counterweight which is movable as a function of the swiveling movement of the superstructure. The counterweight being arranged on the superstructure. The at least one counterweight is connected with the superstructure via an articulation which has a swivel axis aligned parallel to the vertical axis of the superstructure.

摘要： Cranes having multisection booms have an apparatus for interconnecting boom sections mounted at the ends of the boom sections. The apparatus for interconnecting the boom sections has: on a first boom section, an upper hook member with its concave portion being concave inwardly towards a central longitudinal axis of the boom section; on a second boom section, an upper fork member, having a pair of extending flange portions supporting a bolt member for being received within the upper hook member during interconnection; upper abutment surfaces, which are planar and are perpendicular to the central longitudinal axis of the boom sections, and which are located on the end of the upper hook member and between the pair of flanges of the upper fork member; and a lower strap member on a first boom section for being disposed within a lower fork member on a second boom section during interconnection.

摘要： A crane, particularly a large mobile crane, including an undercarriage (1); a revolving joint (3) on the undercarriage (1); and a superstructure on the revolving joint (3). The superstructure includes a central part (5) rotatably mounted on the revolving part (3), a boom connected to the central part (5), a swing part (6), and a horizontal swing bearing (9) pivotally mounting the swing part in upwardly swingable manner on the central part (5). The crane further includes at least one winch mounted on the swing part (6) and a retraction mechanism at the end of the swing part (6) opposite the swing bearing (9). The retraction mechanism includes a pulley head (16) and a bracing (25) for the boom.
