Abstract

A hydraulically operated pivotal joint for damping a swing motion of a swing damping device, the hydraulically operated pivotal joint comprising a non-pivoting pin, a first inner channel arrangement comprising a first pressure inlet for providing an inlet for a pressure medium, a first braking arrangement arranged to create a braking force for damping the swing motion. Wherein the braking force is provided by the first braking arrangement by means of pressure provided by the pressure medium conducted to the first braking arrangement via the first inner channel arrangement. The first inner channel arrangement comprises a first pressure outlet, wherein the pressure medium is conducted from the first pressure inlet through the non-pivoting pin and through the first braking arrangement to enable conducting of the pressure medium for a second hydraulically operated moving apparatus of the swing damping device.
