An installation comprises part-carrying pallets (10) of general rectangular shape which are displaced in elementary modules (46) under the frictional action of at least one drive run (50), displacement of the pallets being effected by way of rollers (32) provided on the pallet and rolling on the respective bottoms of the modules. The pallet (10) comprises a body (12) below which are mounted idler wheels (26) disposed horizontally to provide for guiding and/or driving of the pallet, each module (46) comprises at least one guide rail (62) defining a circulation path of selected shape and made of an elastically deformable material, in such a way that during the displacement of the pallet on a module the guide rail (62) exercises an elastic return force against at least one idler wheel (26) of the pallet in such a way as to urge at least one drive portion (18) of the pallet into elastic contact against the drive run of the module.
