<p>A dock leveler system (14) includes a pivotal deck (16) whose movement provides the impetus for moving a bumper (34) between an operative position and a retracted position. The bumper (34) is movable relative to the deck (16), so that after a truck (12) bumps up against the bumper (34), the bumper (34) can move below the deck (16) to avoid creating an obstacle to a forklift or the like travelling on the deck (16). The moveable bumper (34) can be disposed within the width of a dock leveler deck (16) that encompasses the full-width of a truck bed (16). Of the various embodiments, some bumpers (34) pivot underneath the deck (16), and others move straight up and down. In the operative position, some bumpers (34) are flush with the top of the deck (16), and others protrude above the deck (16).</p> |
