Workpiece carrier system

A work piece carrier system, comprising:

• a fixed base element;
• a drivable traction element revolving at the base element;
• a work piece carrier;
• and
• at least one guide rail, arranged at the base element, and configured to guide rollers of the work piece carrier,
• wherein the work piece carrier includes a coupling device, configured to couple the work piece carrier with the traction device by friction locking,
• wherein the work piece carrier includes a plurality of the rollers that are supported at the guide rail so that the work piece carrier is supported by the rollers to roll on the base element,
• wherein the coupling device is configured to exclusively engage a top side of the traction device oriented away from the base element when coupling with the traction device through friction locking,
• wherein the guide rail includes a stop for the rollers, wherein the stop is oriented away from the base element so that a lifting of the work piece carrier from the base element during coupling engagement of the coupling device at a top side of the traction device is limited by the stop.
