A hydraulic drive for a press and in particular for a press for the simulation of the operating conditions of mechancial presses for large parts or the like is proposed. In order to also make such a hydraulic simulation press available for pilot lots or small lots with a considerable improvement in efficiency, a so-called hydraulic transformer, which consists of hydraulic devices adjustable in angular travel, is assigned to the drive.
