  • Vibration insulation system in compactors
    Patent number: 5104257
    Abstract: The present invention relates to a vibration insulation system for a self-propelled vibrating compactor providing a chassis supporting a roller and a chassis supporting both a cabin and elements for self-propulsion of the compactor. The chassis supporting the roller is connected to the chassis supporting both the cabin and the elements for self-propulsion by a series of shock absorbers connected to a cross bar, whereby vibrations of the roller are prevented from being transmitted to the chassis supporting the cabin and self-propulsion elements.
