<p>To prolonge the life duration of grate bars presenting at one of their ends attachments for grate-bar fixing members, at the other end a supporting part for a support which is preferably inclined on another bar, there is provided at both end portions of the bar a hollow-shaped attachment (17) and a support part (15). The bar may thus be turned in case of wear (21) of the bar end used as a supporting part and be placed by means of its attachment to said worn end. </p> |
