The high load vibration arrestor of the present invention comprises: a vibration body support part having first bearing parts; rotating shafts rotationally provided to the bearing parts, having eccentric parts which are eccentric with respect to the rotation centers of the rotating shafts, and spaced from each other at predetermined intervals; second brackets having second bearing parts for rotationally supporting the eccentric parts; an attachment main body; elastic members provided between the first and second brackets or between the vibration body support part and the second bearing parts so as to elastically bias the second brackets with respect to the vibration body support part in the upward direction; and rotation synchronization units provided to the rotating shafts so as to synchronize the rotation directions of the rotating shafts according to the vibration. The high load vibration arrestor, according to the present invention, can be applied to various construction equipment, excavators, and the like and can prevent the vibration generated from various attachments and the like from being transmitted to the excavator or the boom of the construction equipment or the vehicle body.

Cette invention concerne un dispositif d'arrêt de vibrations sous charge élevée, comprenant : une partie de support de corps de vibration présentant de premières parties de palier ; des arbres de rotation montés rotatifs sur les parties de palier, comprenant des parties excentriques qui sont excentriques par rapport aux centres de rotation des arbres rotatifs, et espacés les uns des autres à des intervalles prédéterminés ; de seconds supports comprenant de secondes parties de palier destinées à supporter en rotation les éléments excentriques ; un corps principal de fixation ; des éléments élastiques disposés entre les premiers et seconds supports ou entre la partie de support de corps de vibration et les seconds éléments de palier de façon à solliciter de manière élastique les seconds supports par rapport à la partie de support de corps de vibration dans le sens ascendant ; et des unités de synchronisation de rotation montées sur les arbres de rotation de manière à synchroniser les sens de rotation des arbres rotatifs en fonction de la vibration. Ledit dispositif d'arrêt de vibrations sous charge élevée, peut être appliqué à divers engins de chantier tels que des excavatrices et similaires et il peut empêcher la transmission des vibrations générées par divers accessoires et analogues vers l'excavatrice ou la flèche de l'engin de chantier ou de la carrosserie de véhicule.
