Example embodiments of the invention generally relate to a dampening and impact absorption device including a first component, a second component, and at least one elastomeric element operatively coupled between the first component and the second component. Other example embodiments of the invention generally relate to a dampening and impact absorption system including one or more such dampening and impact absorption devices. In example applications, the dampening and impact absorption device is utilized to dampen and reduce impacts, forces and noise between the platform and anchor pilings of a floating dock system, for example resulting from wave action or other dynamic effects.

The impact compactor includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.

The present document shows a spring suspension device for an agricultural implement, including a casing, a beam extending through the casing, and four spring elements disposed in a space between the casing and the beam. The casing and the beam are resiliently rotatable relative to each other about a rotational axis extending along a longitudinal direction of the beam. The spring elements differ substantially from each other with respect to shape or material properties, and first and second side faces of the beam, which interact with the respective spring elements, differ substantially from each other with respect to the radius of curvature, viewed in a plane perpendicular to the longitudinal direction.
