PL PLThe subject of the invention is a type of grillage mounting that allows the production of very thin grillages by giving the cross girders the shape of boxes consisting of, for example, two sections of C-type iron or the like, in such a way that the said sections are turned sideways towards each other, and between the edges of the sides of the C-sections there is a gap, as a result of which the side projections of the grillage bars, shaped like a dovetail, can be inserted between the C-sections, thanks to which a loose fastening of the grillages in the cross girders is created. The subject of the invention is shown in the drawing, showing a longitudinal cross-section of the movable part of it. -grate. In the side articulated chains a, transverse girders 6 are fastened, consisting of two channels. The height of the channels is selected in accordance with the width of the grate. Between the girders b, grate c are mounted by means of projections d with such considerable clearance that the grate bars of one row are placed with their free ends e during the movement in the furnace proper on the ridges f of the next row of grate bars c, while during the idle movement under the furnace, they rest with their projections g on the sides of the channels so that they hang loosely and can swing without falling out, which would cause excessive lowering (downwards) of the grate bar ends e during the movement in the furnace proper and during Changes in the direction of movement are prevented by contact between the projections k and the sides of the C-sections 6.
