Example of an overhead transport system:

What is the translation of "overhead transport system" in French?

• Google Translate says: "GPU discret".

• linguee.com returns no interesting results.

• Google Translate says: "système de transport aérien", which sounds ambiguous to me, as aérien may refer to planes (e.g., compagnie aérienne).

• linguee.com returns "système de transport suspendu au plafond". I wonder if "suspendu au plafond" can be shortened.
