The present invention provides a vibration damping device for an excavator, the vibration damping device comprising: a connecting body having a tubular shape with two open ends, wherein the two ends in the longitudinal direction are each connected and coupled to the excavator; and a motion absorber which is connected and installed on the connecting body, and which converts vibration and impact force generated during an attachment operation of the excavator into kinetic energy through a bending motion, and then absorbs the kinetic energy.
La présente invention concerne un dispositif d'amortissement de vibrations destiné à une excavatrice. Le dispositif d'amortissement de vibrations comprend : un corps de liaison, dont la forme tubulaire présente deux extrémités ouvertes, les deux extrémités étant chacune reliées et accouplées à l'excavatrice selon la direction longitudinale ; et un absorbeur de mouvements, relié et installé sur le corps de liaison et convertissant les vibrations et la force d'impact générées pendant une opération de fixation de l'excavatrice en énergie cinétique par un mouvement de flexion, puis absorbant l'énergie cinétique.
본 발명은, 양단이 개방된 관 형태를 가지며, 길이방향 양단은 각각 굴삭기에 연결 결합하는 연결 몸체, 연결 몸체에 연결 설치하며, 굴삭기의 어태치먼트 작동시 발생하는 진동 및 충격력을 휨 운동을 통한 운동에너지로 변환시킨 후, 운동에너지를 흡수하는 운동 흡수체를 포함하는 굴삭기용 진동감쇠장치를 제공한다.
