본 발명에 따른 케이블의 진동을 감쇠시키기 위한 장치(22)는 피봇(26) 주위로 진동하는 암(25); 암의 진동 중 적어도 일부를 감쇠시키기 위한 제 1 댐퍼(30); 케이블(16)에 부착된 커플러(27); 상단부는 커플러에 연결되고 하단부는 암에 연결된 선형행정을 갖는 제 2 댐퍼(31); 및 제 2 댐퍼의 행정에 횡방향으로 케이블의 움직임이 제 2 댐퍼에 무관하게 암에 보내지도록 제 2 댐퍼의 행정에 평행한 암에 대해 커플러가 슬라이드하게 하는 가이드(28)를 구비한다. A device (22) for damping vibrations in a cable (16) comprises an arm (25) oscillating about a pivot (26), a first damper (30) for damping the oscillations of the arm, a coupler (27) attached to the cable, a second, linear-travel damper (31) having an upper end connected to the coupler and a lower end connected to the arm, and a guide (28) for sliding the coupler with respect to the arm parallel to the travel of the second damper such that the movements of the cable that are transverse to the travel of the second damper are transmitted to the arm independently of the second damper.
