<p>A turntable for a conveyor system has a main frame, a plurality of load-carrying rollers supported by the main frame for rotation about transverse axes to transport a load between upstream and downstream ends of the conveyor system, a lift frame supported by the main frame, a load-supporting table carried on the main frame, and glide rollers for allowing rotation of the table relative to the lift frame. Air jacks move the lift frame between a first position where the table is slightly below the load-carrying rollers to allow the load to be transported over the load-carrying rollers and a second position where the table is above the load-carrying rollers to lift the load off the load-carrying rollers. A lift-leveling mechanism provides level movement of the lift frame relative to the main frame and includes a plurality of guide plates mounted on the main frame. Each guide plate includes at least one slot, a guide bar coupled to the lift frame, a guide post engaging the slot, and linkage rods interconnecting the guide bars.</p> |
