Abstract: A pallet stop generally comprises a support frame, an internal enclosure, a rotating actuator, a pivoting stop, and a counterweight assembly. The rotating actuator has an upper arm portion that extends just above the surface of the enclosure. The enclosure is received in and supported by the support frame. As a pallet load moves across the enclosure, its leading edge will contact the upper arm portion of the rotating actuator, which causes it to rotate clockwise. A lower portion of the rotating actuator is positioned below the pivoting stop. As the rotating actuator rotates clockwise, the lower portion of the rotating actuator moves downwardly, thus allowing a counterclockwise rotation of the pivoting stop. Once the pallet load travels over the rotating actuator, the counterweight assembly causes the rotating actuator to return to the upright position to ensure a proper positioning of the pallet load.
