ABSTRACT:
A vibratory plate includes a ground plate, a vibration generator adjacent the front of the ground plate and a motor driving the vibration generator. The ground plate includes a sole plate, an upwardly inclined portion at the rear of the sole plate, two successive upwardly inclined portions at the front of the sole plate and an upwardly and rearwardly inclined portion from the front of the ground plate to the casing of the vibration generator. Extending downwardly from the casing of the vibration generator to the ground plate are supporting ribs positioned in the planes of the bearings of the vibration generator. A transverse rib extends upwardly from the ground plate at the rear of the supporting ribs. The ground plate, the ribs and the casing are an integral unit. In one embodiment that unit is cast aluminum with a steel facing on the bottom of the sole plate. In a second embodiment they are fiberglass reinforced plastic with a steel facing on the bottom of the sole plate.
