Abstract
A vibratory roller is disclosed having a frame comprised of pivotally interconnected front and rear subframes. A motor is mounted on the frame and a steering mechanism is provided to articulate the subframe relative to each other. A roller drum carrier is mounted by a longitudinal centerline suspension system to support each of the subframes. Ground engaging roller drums are rotatably mounted on the roller drum carrier for rotation about an axle axis. An exciter mechanism for generating a vibratory compacting force is mounted in the roller drum carrier below the axis. Hydraulic drive units for rotating the roller drums are mounted in the roller drive carrier above the axis.
