Device for removing materials carried in a water current (1) with a grid with parallel rods that can be placed crosswise in the water current, extending above the water surface and behind which means (6) are located for catching material that has been removed from the water current, and with at least one beam (4) that has a row of teeth (3) which can be made to move over the total height of the grid round a closed circuit about this grid. According to the invention, there is at least one section (8) of the grid behind the circuit (5) of the said beam (4) in such a fashion that the grid can be supported at the rear, in particular by cross beams.<IMAGE> |
