The present invention provides a vibration damping device for an excavator, which comprises: a connection body connected and installed in a boom or an arm of an excavator and having a pipe shape of which both ends are opened; and a pair of movement absorbing bodies of which one end is coupled and installed to each longitudinal end part of the connection body and the other end is extended to be inserted into the connection body to convert and absorb vibration and impact force transmitted from an attachment into bending movement.
본 발명은, 굴삭기의 붐 또는 암에 연결 설치하며, 양단이 개방된 관 형태를 가지는 연결 몸체, 일단이 연결 몸체의 길이방향 각 단부에 결합 설치하며, 타단은 연결 몸체의 내측으로 삽입되도록 연장 형성되어 어태치먼트로부터 전달되는 진동 및 충격력을 휨 운동으로 변환 흡수하는 한 쌍의 운동 흡수체를 포함하는 굴삭기용 진동감쇠장치를 제공한다.
