Abstract
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 includes a vibrating table and a hydraulic exciter device for driving the vibrating table. The hydraulic exciter device includes a plurality of hydraulic exciters 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. An improved hydraulic exciter for use in the improved compacting device, and the improved compacting device with a single improved exciter of this type are also described.
