Zusammenfassung:An actuation system includes: two hydraulic actuators, each being coupled to a load-bearing structural component and to an elevator, and displaceable relative to the load-bearing structural component for the operation of the elevator; a first control valve device to control the first actuator; a second control valve device to control the second actuator; a control and monitoring unit that determines and transmits appropriate command signals to the control valve devices to execute appropriate control movements for the operation of the actuators; a locking device coupled to the first actuator to secure the first actuator a locked state, which is hydraulically connected with the first hydraulic system and the second hydraulic system via an hydraulic OR-circuit, where in normal operation the locking mechanism is in its unlocked state, and in the event of a failure of both hydraulic systems the locking mechanism secures the first actuator.
