ABSTRACT:
A dock leveler has a barrier actuated by movement of the lip. The barrier is mounted for pivotable movement to be flush with the deck when the lip is extended. As the lip is lowered an arm contacts a guide plate mounted on said carrier to rotate said barrier upward. As said lip raises the guide plate lowers by gravity.
