The invention relates to an actuator 1 for a lift system, which actuator can adopt an activated state and a released state, and has a restoring element 15. The actuator is brought from the released state into the activated state by means of said restoring element. The restoring element is made of a shape memory alloy. At a first temperature, the restoring element adopts a first length, and a second length at a second temperature. After the actuator has been released, the restoring element is designed to change from the first length into the second length, and back into the first length. In this way, the restoring element returns the actuator to the activated state. |
