Patent ID: 7743910

Claim:
A mechanical arrangement for moving workpieces and/or processing remnants from processing of a workpiece, the mechanical arrangement comprising: a load carrier that can be loaded with a workpiece, with a processing remnant, or with both a workpiece and a processing remnant, and a load carrier drive that moves the load carrier into a target position, the load carrier drive including a drive motor, a rigid drive chain, and a chain driving wheel, supported on the load carrier and drivingly connected with the drive motor, which, when driven by the drive motor, acts on the rigid drive chain on a site of action of the chain driving wheel, the rigid drive chain being configured to convert a driving movement of the chain driving wheel into a movement of the load carrier into the target position, wherein the rigid driving chain is braced against a chain abutment, relative to which the chain driving wheel moves together with the load carrier.
