Abstract: A device for handling bulk material, especially in marine transportation, comprises a pressure vessel having at least two members for mechanically enclosing a volume of the bulk material to be conveyed. The pressure vessel is equipped with pressure fluid activated push rods for moving the two members between an open and closed position to thereby grab a volume of the bulk material. The two members are preferably two essentially identical halves. A supply conduit is connected to the pressure vessel for supplying a pressurized gas thereto. A discharge conduit is connected to the pressure vessel for conveying the volume of bulk material out of the pressure vessel with the aid of the pressurized gas.
