| 65 | Moveable bumper for a dock leveler | US09850430 | 2001-05-07 | US06634049B2 | 2003-10-21 | Norbert Hahn; Michael A. Swessel; Edward A. Raleigh |
| A dock leveler system includes a pivotal deck whose movement provides the impetus for moving a bumper between an operative position and a retracted position. The bumper is movable relative to the deck, so that after a truck bumps up against the bumper, the bumper can move below the deck to avoid creating an obstacle to a forklift or the like traveling on the deck. The moveable bumper can be disposed within the width of a dock leveler deck that encompasses the full-width of a truck bed. Of the various embodiments, some bumpers pivot underneath the deck, and others move straight up and down. In the operative position, some bumpers are flush with the top of the deck, and others protrude above the deck. | ||||||

| A bumper assembly for a loading dock includes a bumper that is moveable between an operative position and a stored position. In the operative position, the bumper extends well above the dock platform to prevent excessively high trucks, trailer beds, and cargo containers from being parked over the top of the dock platform. In the stored position, the bumper is positioned so as not to obstruct loading and unloading of cargo. In some cases, the bumper is biased to the operative position to encourage operators to normally leave the bumper in that position. In some embodiments, the bumper is selectively moveable away from the vehicle or container that the bumper is blocking to facilitate subsequently moving the bumper to its stored position. | ||||||
