Abstract

A shield system for shielding the area underneath a dock leveler allows a gap to be created either above or below the shield when the deck rises, whereby a shield of a given height dimension can used on dock levelers of various lift heights. In some embodiments, the shield is a pliable curtain that a tensioner holds taut during some operations of the dock leveler, yet the curtain can collapse for below-dock operation. The shield system can be used on horizontally storing dock levelers or vertically storing ones. In some cases, the system includes a pliable web that extends between a front face of the deck and a lip extending from the deck. The web can help seal the area adjacent to a pair of dock bumpers.
