Abstract
A vibrating plate consists of an upper mass with a drive unit and a lower mass with a ground contact plate and a vibration exciter. The upper mass and lower mass are coupled with each other at several points with spring-and-damper units. According to the invention, the spring properties and/or damping properties of the particular spring-and-damper unit in at least one of these points can be modified via a steering device which makes it possible to steer the vibrating plate.
