ABSTRACT:
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.
