A suspension apparatus is provided for interposition between a support structure, such as a crane, and a vibratory device, such as a vibratory ram. The apparatus includes a sling element having two first ends spaced apart in the direction of pull, with one of the first ends suspended from the support structure and the other first end holding the vibratory device. The sling element also has two second ends, which second ends are spaced apart in a direction transverse of the pulling direction. A resiliently distortable damping element is interposed between the two second ends, and serves to dampen oscillations produced when the suspension apparatus is subjected to vibratory loading of the first ends.

A suspension arrangement for suspending a vibratory ram and the like vibratory devices or bodies, comprising a sling element having two first upper and lower ends spaced from one another in a vehicle first direction and two second lateral ends spaced from one another in a second transverse direction

A suspension arrangement for suspending a vibratory ram and the like vibratory devices or bodies, comprising a sling element having two first upper and lower ends spaced from one another in a vehicle first direction and two second lateral ends spaced from one another in a second transverse direction which is transverse to said first vertical direction; carrying plates mounted at the respective first ends; first and second suspending means each connected to one of said carrying plates so that, when said sling element is suspended from one of said suspending means and a vibrating element is suspended from the other of said suspending means, said sling element varies its shape whereby the respective distances between said first ends and between said second ends are varied; and a dampening element located between said second ends of said sling element and movable in said transverse direction so that when said sling element is loaded by the vibrating element suspended on said one first end and the distance between said second ends is varied, a compressing force acts upon said damping element in said transverse direction.
