A lifting apparatus for magnetic tape cartridges in a tape transport system or tape autoloader has a lifting platform supported by threaded lead screws. The threaded lead screws extend through threaded nuts held in the platform by floating mountings. A preferred embodiment has three lead screws and three types of floating mountings. The first restricts lateral and rotational motion, the second restricts rotational motion and lateral motion in one direction while permitting motion in a transverse direction, and the third floating mounting permits rotational and lateral motion, to a limited extent. A toothed belt over cog wheels drives the threaded lead screws to move the platform vertically.
