<p>A carriage has a pivot frame which receives individual pallets. When full, a latch is released and the frame is pivoted on a base by springs into a position parallel to inclined roller tracks. An operator pushes the carriage along the tracks to an unload station, where a stack of pallets is engaged by ramps leading to elevated roller tracks. Forward movement discharges the stack to the elevated tracks, and the carriage is drawn back to the starting position, where a latch is released to allow the pivot frame to return to its original orientation against the resistance of an air cylinder. A foot latch retains the carriage within the unload station during loading.</p> |
