The vibrating part is provided with two eccentric axles (4, 5) each driven by its own hydraulic motor (7, 8). The axles are located on either side of the centre of gravity for the vibrating part and rotate independently from each other. The flow of hydraulic fluid to the motor is regulated by a valve. As the plate is moved backwards and forwards, energy from the previously driven axle is used to acceleration rotation of the hydraulic motor being used to provide the drive force for moving the plate. |
