Abstract

The invention concerns an arrangement related to a crane, in particular a crane intended for forestry machines and similar, whereby the crane (3) comprises a first crane arm (10) and a second crane arm (11) that are attached to each other in a manner that allows swinging through a swing joint (X2). A further swing joint (Yl) is arranged in a transitional region between the first crane arm (10) and the second crane arm (11), whereby the swing axes (X2,Y1) of the rotational joints are essentially perpendicular to each other. The additional swing joint (Yl) is constituted by a joint arrangement (30) that comprises a first joint part (40) and a second joint part (60), whereby the first joint part (40) is connected to the swing joint (X2) of the first crane arm (10), that the second joint part (60) is connected to the rear end part (1 laa) of the second crane arm. The arrangement according to the invention makes possible a good access and a large working area.
