Abstract

PURPOSE:To improve the effect of damping the oscillation of ropes by locating the locus of the junction of a connecting member pivotally supported and provided with a braking resistance and flexible rope outside of a sphere of a diameter 80 times as large as the diameter of the rope. CONSTITUTION:A swing lever 11 which swings with the oscillation of a weight compensation rope 7 is rotatable perpendicularly to the paper under a friction between a universal joint 12 and the swing lever 11 and laterally under a friction between the joint 12 and a hanger 13. The rotation of the swing lever 11 is damped by the said frictions. When the length of the swing lever 11 is long enough to provide a locus of a junction 10 in the space outside of a sphere 14 of a diameter 80 times the diameter of the rope 7, the swing lever 11 is rotated following the movement of the rope 7 if the rope 7 is oscillated in a wide amplitude by a weak force effectively damping the oscillation of the rope 7.
