Abstract

The invention relates to an arrangement and to a method related to a swing damper, particularly to a swing damper (1) for supporting a tool (5) that hangs from a crane arm (2) or some similar structure. The swing damper (1) includes an upper part (11), which is connected to the crane arm (2), and a lower part (12) that carries a work tool (5) or some similar device either directly or via a rotator (4) for instance. The upper part (11) and the lower part (12) are pivotally interconnected via a pivot joint (13), wherewith the swing damper (1) includes a brake arrangement (50) in the form of a male-female-cone arrangement. Either the upper part (11) or the lower part (12) carries two mutually opposing female cones (52, 53). The part that lacks the female cones carries two mutually opposing male cone parts (60, 61). The conical surfaces of the male cone parts and the female cones are in mutual contact in effecting a braking operation, and the conical surfaces of the male cone parts and the female cones also function as bearing surfaces between the upper part (11) and the lower part (12). An outer portion (64, 65) of the male cone parts (60, 61) functions to transfer load to that part which lacks said female cones (52, 53).
