Abstract: Provided is a vibration damper for a high load, including: a vibration body support portion having first shaft support portions; rotation shafts that are rotatably installed at the first shaft support portions, have eccentric portions eccentric with respect to rotation centers of the rotation shafts and are spaced a predetermined gap from each other; a support portion having second shaft support portions on which the eccentric portions are rotatably supported; an elastic member that is installed between the vibration body support portion and the support portion or between the vibration body support portion and the second shaft support portions and that elastically supports the support portion with respect to the vibration body support portion in an upward direction; and a rotation synchronization unit that is installed at the rotation shafts so as to synchronize rotation directions of the rotation shafts according to vibration.

Abstract: A vibrating ripper, according to the present invention, has: a main body portion; a vibrating body which is coupled to the main body portion and a vibrating body support unit and vibrates; and a vibration generating unit which is provided on the vibrating body, wherein the vibrating body support unit has a rotating member rotatably provided on the vibrating body or the main body portion for supporting the vibrating body, has first and second connecting members of which both end portions are rotatably connected to the upper and lower sides of the rotating member, with respect to the rotating center of same, and to the main body portion or the vibrating body, respectively such that the vibrating body can be supported in accordance with the main body portion, has a ripper blade provided on the vibrating body, thereby, when the vibrating body vibrates in accordance with the main body portion, offsetting, by means of the rotating of the rotating member, the change in coupling positions of the first and second conn

Abstract: Provided is a vibration-type nipper. The vibration-type nipper comprises a body including a vibration space and a coupling unit for coupling with a boom positioned at an upper portion or a fixing bracket of heavy equipment, a housing positioned in the vibration space and including a vibrator, a plurality of supporting member to opposite sides of the housing and the body corresponding to the housing and supporting the housing allowing the housing to vibrate, a nipper blade installed on the housing and extending downwards, and vibration-dampening member mounted on the body at an upper portion of the vibration space and distributing vibration generated when the housing collides with the body due to elevation of the housing.
