Zusammenfassung: | An actuator comprises a first actuator arrangement operable to allow relative axial movement to occur between a first component (16, 44) and a second component (18, 46), a second actuator arrangement operable to allow relative axial movement to occur between a third component (28, 48) and a fourth component (26, 50), brake means (30, 52, 66) operable to prevent extension of the first and/or second actuator arrangement, and damping means (72) operable to control the rate of extension of at least one of the first and second actuator arrangements. |
