The invention relates to a crane, in particular for offshore applications. The crane comprises a bearing device (7) for assembly between a base (5) and a load-bearing frame (6). The bearing arrangement (7) is distributed over the height of the support structure (3) and comprises an upper bearing arrangement (71) comprising a radial contact rolling bearing (71) comprising rolling elements (711) and a smooth cylindrical raceway (712) coaxial to the axis of rotation (6 '). A radial contact rolling bearing (71) allows a degree of freedom of longitudinal translation of the rolling element (711) over the height of the cylindrical raceway (712).

    本发明涉及一种特别是用于海上应用的起重机。该起重机包括用于组装在基座(5)与承载框架(6)之间的轴承装置(7)。该轴承装置(7)分布在所述支承结构(3)的高度上并且包括上轴承装置(71),该上轴承装置包括径向接触滚动轴承(71),该径向接触滚动轴承(71)包括滚动元件(711)和与旋转轴线(6')同轴的光滑的圆柱形滚道(712)。径向接触滚动轴承(71)允许所述滚动元件(711)在所述圆柱形滚道(712)的高度上的纵向平移自由度。
