ABSTRACT:
A conveyor for use in a travelator for transporting passengers in a transport direction. The conveyor comprises a frame; a plurality of shafts mounted on the frame substantially transversely to the transport direction, each of the plurality of shafts being substantially parallel to one another and spaced apart from one another. A belt pulley pack is mounted on each of the shafts, each belt pulley pack comprising a plurality of belt pulleys mounted adjacent to one another. Each belt pulley comprises a mold-cast object comprising: a first side having a first aligning and coupling element formed therein; a second side opposite to the first side, the second side having a second aligning and coupling element fitted to match the first aligning and coupling element, so that the first and second aligning and coupling elements of adjacent belt pulleys align and couple the adjacent belt pulleys together in a shape-locking manner. A moving transport surface comprises a plurality of mutually parallel endless belt loops, each of the belt loops passing over two belt pulleys located on different shafts.
