Abstract: A mechanical arrangement for moving workpieces and/or processing remnants from processing of a workpiece comprises a load carrier and a load carrier drive. Part of the load carrier drive is formed by a rigid chain which is acted upon by a chain driving wheel supported on the load carrier. Owing to that action, the chain driving wheel takes the load carrier with it to a target position. In the process, the chain driving wheel moves together with the load carrier relative to a chain abutment against which the rigid chain is braced. Systems for processing workpieces are provided, which make use of a mechanical arrangement of the above-mentioned kind.
