(54) SWING DAMPER OF A HANGING ROTARY JOINT


(57) The present invention relates to a swing dampener 1 for a hanging rotary joint for dampening swing movement between a jib and a work device hanged from the jib by said rotary joint. The swing dampener 1 is mounted at the end of the joint pin 2 and comprises two pressure discs 3 and 4 coaxial with the joint pin 2, wherein the rotation of said pressure discs 3 and 4 around the longitudinal axis of the joint pin 2 is fixed in relation to one half of the rotary joint. Between said pressure discs 3 and 4 there is a friction disc 5 coaxial with the joint pin 2, where the rotation of said friction disc 5 around the longitudinal axis of the joint pin 2 is fixed in relation to another half of the rotary joint. The friction disc 5 comprises at least one through opening 8, comprising a friction element 6, having two opposite planar parallel contact surfaces, which are pressed by the pressure device 7 into contact with the pressure discs 3 and 4 at the opposite sides of the friction disc 5.
