Abstract

Control for regulating the direction of the vibrational force in plate vibrators for compacting gravel, sand and similar materials and which are equipped with a vibrating element consisting of two or more contra-rotating eccentric weights. Particularly characteristic of the control is that it acts on the adjusting mechanism (4) of the vibrating element by means of a wire (4) and that its control (3) can be held in the set position by means of a spiral spring (7) interacting with a friction brake (11).
