Abstract
A two hand safety control mechanism for a consumer actuated by pressure medium includes a safety valve blocking the supply of pressure medium during a faulty switching and venting the consumer. For maintaining a working position of the consumer, a plurality of control valves are provided which are dynamically self-regulating. By actuating a further control valve, the automatic retention can be cancelled in order to allow the consumer to return in its idle position.
