An adjustment device for adjusting the position of at least one strand supporting element (,) relative to a supporting stand (,) carrying at least one further strand supporting element (,), of a strand guide in a continuous casting plant comprises at least one hydraulic adjustment cylinder (,) contacting a strand supporting element (,) directly or indirectly on the one side and the supporting stand (,) carrying a further strand supporting element (,) on the other side, the movement of the strand supporting element (,) being detectable via a position sensor (,) and controllable by means of an automatic controller (,). In order to safely attain the high precision in positioning the strand supporting elements (,) sought for a strand guide at yet a minimum expenditure and a minimum susceptibility to failure, at least one directional control valve (,A,,B) capable of being switched via a three-level controller (,) is provided for actuating the hydraulic adjustment cylinder (,) FIG.,.
