Constant radius dock leveler hinge

摘要

A dock leveling system (100) adapted to be disposed in a pit (110) is disclosed. A hinge member (116) with a hinge pin receiving area (118) and a hinge pin (120) disposed in the hinge member defines a center of rotation. A deck (108) that is rotatable about the hinge pin includes a curved portion (144) with a constant radius and a center of curvature substantially similar to the center of the hinge pin. The curved portion defines an elevation (150) that remains constant as the deck rotates about the hinge pin. <IMAGE>
