<p>An overhead conveyor or transport system (10) is disclosed where at least one carriage (28) is supported on a plurality of rollers (24) rotatably mounted in fixed overhead locations spaced along a path of travel. At least one motor (26) is provided for driving a portion of the plurality of rollers in rotation along at least one segment of the path of travel. Each carriage has at least one elongate support member (30) operably engagable with the rollers for movement along the path of travel in response to rotation of the rollers. The elongate support member is continuously engagable with at least two rollers simultaneously while the corresponding carriage is moved along the path of travel. Each carriage or carrier hangs downwardly below the rotational axis of the overhead rollers. <IMAGE></p> |
