Abstract

The invention relates to an actuating device for the activation of a hydraulic load (10), such as a working cylinder, by means of a fluid supply flow. As a result of the fluid supply flow for the load (10) being activated by means of an activating unit (48) in such a way as to obtain a damped actuation with a soft starting behaviour, soft accelerations fundamentally occur for a hydraulic load, which soft accelerations are perceived by an operator to be comfortable with regard to the continuous speed behaviour.
