ABSTRACT:
A soil compactor comprises a non-circular tamping roller the axis of which performs a translatory oscillating motion during operation, mounted through a pneumatic suspension system to a draw frame. The springing characteristics of the suspension system are selected so that, in combination with the mass of the frame and the frequency of oscillation of the roller axis, the frame is substantially isolated from the vertical component of the oscillatory motion at a chosen speed.
