Abstract
A device and a method for moving an object in a vertical direction are disclosed. The device includes a plurality of piezo-actuators expanding in directions upon activation and in doing so generating pressure forces on an active side, and a hydraulic transmission device that converts the pressure forces of the piezo-actuators into a vertical pressure force for moving the object opposite the direction of gravity and transmits the pressure force with a transmission ratio. The object is lifted after the vertical pressure force has exceeded an oppositely acting spring force of a spring system.
