<p>The invention relates to an improved compacting device for compacting a granular, loosely coherent mass, such as soil-moist cement, for producing end products such as tiles, kerbstones and the like. The compacting device comprises a vibrating table (1) and a hydraulic exciter device (63) for driving the vibrating table (1). The hydraulic exciter device (63) comprises a plurality of hydraulic exciters (3) and is configured to drive the hydraulic exciters with excitation displacements of mutually substantially the same amplitude and frequency and in phase with one another. The invention furthermore relates to an improved hydraulic exciter for use in the improved compacting device. The invention furthermore relates to the improved compacting device with a single improved exciter of this type.</p> |
