ABSTRACT:
A dock leveling system adapted to be disposed in a pit is disclosed. A hinge member with a hinge pin receiving area and a hinge pin disposed in the hinge member defines a center of rotation. A deck that is rotatable about the hinge pin includes a curved portion with a constant radius and a center of curvature substantially similar to the center of the hinge pin. The curved portion defines an elevation that remains constant as the deck rotates about the hinge pin.
