A dock leveler includes a pivotally extendable lip coupled to a pivotal deck by way of a front hinge, wherein the structure in the area of the front hinge optimizes the torsional flexibility of the deck; provides a well supported, durable crown (apex angle between an extended lip and the deck); and reduces the part count of the dock leveler. The front hinge includes a deck-hinge member that extends approximately the full width of the deck and is preferably formed from a single sheet of material. A particularly narrow front header or flange disposed along the front edge of the deck reinforces the relatively thin deck plate so that the plate's rigidity more closely matches that of the thicker lip, yet the flange is sufficiently small to allow the deck to twist so that the deck can place the tip of the lip squarely upon a sideways inclined truck bed.

A shaft assembly includes first and second shafts that are easily separable. The first shaft has a longitudinal axis, and includes an output end having an axially opening cavity. The second shaft has an end received in the axially opening cavity. A passageway is formed through one of the first and second shafts and is in fluid communication with the cavity for pumping a fluid through the passageway into the cavity between the first and second shafts to axially urge the second shaft out of the cavity.

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.

To permit below-dock level end-loading operations and to limit accidental freefalling of a dock leveler's deck, a dock leveler includes a unique support mechanism that employs one or more safety legs with an integral or operatively connected lip deflector. The support mechanism can be selectively moved to a deck-supporting position for freefall protection or moved to a lip-deflecting position for below dock level end-loading operations. In the deck-supporting position, the safety leg prevents the deck from falling an unsafe distance. In the lip-deflecting position, the lip deflector guides the descending motion of the dock leveler's lip extension plate so that the lip, while hanging pendant, can bypass and descend below a set of lip keepers.
