Abstract: A grate plate arrangement for stepped reciprocating grates includes a grate plate with a front plate fastened to a front wall in the direction of conveyance. The grate plate includes an adjustment plate being clamped between the front plate and the front wall of the grate plate for adjusting a motion gap between the front end of the grate plate and the following grate plate in the direction of conveyance which forms the next grate step. The adjustment plate is calibrated with the front plate still only loosely assembled, in its vertical position that forms the motion gap, and is held in this position by clamping the front plate.

Abstract: A grate plate arrangement for stepped reciprocating grates includes a box-like grate plate with a front plate fastened to a front wall in the direction of conveyance. Means for adjusting a motion gap between the front end of the grate plate and the following grate plate in the direction of conveyance which forms the next grate step includes a separate adjustment plate, which is non-positively clamped between the front plate and the front wall of the grate plate. The adjustment plate is calibrated with the front plate still only loosely assembled, in its vertical position that forms the motion gap, and is held in this position by clamping the front plate. A clamping bolt for clamping the grate plate on a grate carrier can be arranged such that the clamping bolt aligns with a fixing bolt for the front plate so that the clamping bolt can be actuated though access openings for this fixing bolt.
