A pallet magazine for transporting workpieces from a loading station to an unloading station, and possibly past a working station, has two parallel, endless conveyor chain loops supported on and driven by spaced pairs of sprocket wheels having horizontal axes. A plurality of pallets for carrying the workpieces are adapted to rest slidably on the upper sections of the chains and to hang freely from the lower sections of the chains. A further sprocket wheel is provided between the sprocket wheels of each said pair thereof, and a rack adapted to engage the further sprocket wheels is provided on the underside of each pallet. Each pallet has lateral guide rollers with horizontal axes which engage semicircular guide members provided adjacent the sprocket wheels. A guide rail extends between the further sprocket wheels and is received between spaced guide projections provided on the pallet racks.
