Abstract
A counter balance mechanism for a mechanically-operated, vertically-storing dock leveler that can upwardly bias the dock leveler at desired angles of rotation and downwardly bias the dock leveler at other angles of rotation, and neutrally bias the dock leveler at yet other angles of rotation. A method for assisting the operation of a mechanically-operated, vertically-storing dock leveler of desirable simplicity is also provided.
