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.

Abstract: A recycling control system for a dock leveler including a pivotally mounted deck. There is a powered lifting mechanism for raising the deck and a lip pivotally mounted to the deck for movement between pendant and extended positions. The control assembly includes a lip-position member couplable to the lip for movement therewith such that the position of the lip-position member is indicative of lip position. There is a switch couplable to the lifter and operable to a first condition wherein power is provided to the lifter and operable to a second condition wherein power is not provided to the lifter. There is an actuator disposed on the lip-position member for movement relative thereto between at least a first position where the actuator operates the switch to the first condition, and a second position where the switch can be operated to the second condition. The actuator is disposed to move between the first and second positions as the lip moves toward the pendant position.
