HYDRAULIC EXTERNAL VIBRATORS

Application

Series NGH L hydraulic external vibrators are particularly suitable for emptying containers and bulk material hoppers containing adherent bulk materials, for preventing bridging and tubing and for compacting various materials.
A special characteristic is its use for unloading transport vehicles, e.g. trucks, silo buses and ships.
The Vibratos are driven via the hydraulic system belonging to the carrier vehicle, and are therefore independent of any external energy supply.

Design and functioning principle

The rotary vibration is created by an unbalance. High rotational speeds result in large centrifugal forces.
The rotational speed, and hence the centrifugal force, can be regulated continuously via the volume flow rate.
NHG 500 L, NHG 900 L and NHG 3000 L have fixed working moments. The working moment of the NHG 600 RL can be adjusted is steps, from the outside.
Series NHG L hydraulic external vibrators are also available without an overflow oil line connection.
The pressure in the return line must not exceed 2 bar.
