Abstract
A dynamic damper device includes a damping rod traversing several parallel hoisting ropes for an elevator car adjacent to the car and projecting beyond the outermost ropes. All the ropes are fixed to the damping rod by means of two opposite push plates, and fastening bolts. The rod has one of the projecting end portions longer than the other of the projecting end portions and is provided at the extremity with an additional weight. Thus the device has the center of gravity offset from the mid-point between the outermost ropes.
