ABSTRACT:
For the detachable fastening of the grate bars (4) of a grate for refuse incineration plants, the edge bars of the fixed bar rows (3), which are composed of grate bars arranged side by side and coupled in pairs in each case by a bolt (12) fastened on one grate bar (4) and at the neighboring grate bar projecting through a longitudinal slot (14), are in the form of fastened grate bars (4') and are fastened relative to the side wall by a swivelling prevention fastening, which with a bolt (12') corresponds to the coupling between neighboring grate bars and at the same time can be in the form of a longitudinal fastening and has clamping means which are releasable from the region situated outside a side cheek (2) and which subject the bolt (12') to a pull directed towards the side wall, or else by a correspondingly releasable swivelling prevention and longitudinal fastening. In the case of a fastening serving solely for swivelling prevention, an additional longitudinal fastening is provided, which is releasable from the region situated outside the side wall and is, for example, in the form of a retractable locking means projecting into a bore in the fixed grate bar (4') and anchored to a side cheek (2), and after the release of which the fastened grate bar (4') can be pushed forward and disconnected from the swivelling prevention fastening.
