Abstract (en)
[origin: CH689868A5] The device is based around a vibrating electric motor (3) which is attached to its chassis in such a way as to transmit vibrations to it. One or more handles (4a) are attached at one end of the chassis to allow it to be maneuvered, and a reversible extended handle may be attached to allow movement from a distance. The motor is fitted with a control device which allows the frequency of its vibrations to be varied selectively. The electrical supply to the motor is controlled by a switch, and is in the range between 200 and 400V. The motor is reversible in its direction of operation.
