Vibrating Plate with Individually Adjustable Vibration Generators

Abstract

A vibrating plate comprises an upper mass with a drive, a lower mass with a soil contact plate (12), and a vibration generator device, which belongs to the lower mass and which acts upon the soil contact plate (12). The vibration generator device comprises at least two individual exciters (13) each having an unbalanced shaft (2). The individual exciters (13) can be individually controlled with regard to the rotational speed and/or phase position of the respectively assigned unbalanced shaft (2). A mechanical coupling of the unbalanced shafts (2) is thus unnecessary. The unbalanced shaft (2) of an individual exciter (3) can be rotationally driven by a hydraulic motor (4). The position of the unbalanced shaft (2) is determined in at least one position by a position indicator (7).
