Abstract (en)
[origin: DE19811345A1] A vibrating plate usually consists of an upper mass (1) with a drive unit (2) and a lower mass (8) with a ground contact plate (9) and a vibration exciter (10). The upper mass (1) and lower mass (8) are coupled with each other at several points with spring-and-damper units (7). 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 by means of a steering device (6). This makes it possible to steer the vibrating plate without expending any force and without an expensive hydraulic system.
