A slag remover for discharging combustion residues of an incineration plant comprises a trough, which has a trough housing having two side walls, which define the trough width, and having a trough bottom, and which is intended to collect the combustion residues evacuated from a combustion chamber of the incineration plant. The trough further comprises at least two push rams for pushing the combustion residues out of the trough, and a shaft rotatably mounted in two shaft bearings and on which at least one drive lever cooperating with a cylinder-piston unit and at least two output levers connected to respectively one of the push rams are disposed in a rotationally secure manner. The cylinder-piston unit is here designed such that the push rams move back and forth between a retracted position and an extended position. The drive lever is disposed between two output levers.
