Abstract

A device for the hydraulic positioning of structural component parts, in particular rollers of strand guide segments of a continuous casting installation, with hydraulic cylinders, each of which is divided into a cylinder space and an annular cylinder space by a piston having a piston rod. The cylinder spaces can be connected to a pressure source by of control members. Hydraulic connection lines are reduced or components used are reduced. Either the annular cylinder space is acted upon by a pressure which is adjustable but which then remains constant, while the pressure applied to the piston in the cylinder space is position-controlled or pressure-controlled, or the cylinder space is acted upon by a pressure which is adjustable but which then remains constant, while the pressure applied to the piston in the annular cylinder space is position-controlled or pressure-controlled.
