1. A device for swiveling, turning, and changing workpiece pallets, the device comprising:
two parallel, spaced swivel arms that are each fitted with a respective pallet carrier,
wherein each of the swivel arms can be swivelled via a respective swivel motor and a respective swivel gearing about a substantially horizontal, ground-parallel swivel axis,
wherein each of the pallet carriers can be rotated relative to the corresponding swivel arm via a respective turning motor and a respective turning gearing about a turning axis that is parallel to the swivel axis,
wherein each of the motors is a respective electric motor,
wherein each of the gearings is a respective combined bevel planetary gearing, and
wherein the swivel arms are coupled to each other, so as to be non-rotatable relative to one another, via a line shaft that bridges a distance between the swivel arms, wherein a longitudinal center axis of the line shaft is parallel to the swivel axis.
