PCT No. PCT/FR92/00398 Sec. 371 Date Jan. 4, 1993 Sec. 102(e) Date Jan. 4, 1993 PCT Filed Apr. 30, 1992 PCT Pub. No. WO92/19419 PCT Pub. Date Nov. 12, 1992.An installation for circulating workpiece-carrying pallets. The installation includes a supporting surface and at least one pallet comprising a plurality of self-orientable rolling members supporting the at least one pallet and rolling on the supporting surface. A plurality of sets of substantially horizontally arranged wheels are mounted on the at least one pallet. The wheels include driven wheels and freely rotating guidance wheels. A plurality of rail members are mounted on the supporting surface. The rail members define a plurality of travel paths for the at least one pallet. The rail members interact with the sets of substantially horizontally arranged wheels to guide the pallet on a desired path. Each of the paths is defined at least partially by a section of parallel rail members. These sets of substantially horizontally arranged wheels are compressibly lodgeable between the parallel rail members. The travel paths are connected by a plurality of interconnections. A plurality of actuable rail members are mounted on the supporting surface at interconnections between the travel paths. The position of the actuable rail members may be altered to alter the travel path of the at least one pallet.
