The linear actuator comprises upper and lower frame portions vertically movable relative to one another along a central axis, and first and second bands that intertwine to form an extractable and retractable column. The second band forms the wall of the vertical column, and it is the second band that is supported by a rotor that is rotatably carried by the lower frame portion, to reduce the mechanical stress on the first band.
