ABSTRACT:
A loading dock includes a dock leveler movable between raised and lowered positions. The dock leveler includes a dock board and a lip assembly that can be horizontally extended and retracted relative to the forward edge of the dock board. The ability of the lip to extend and retract horizontally means that the dock board does not have to be raised as far to extend the lip as in prior dock levelers having a pivotally mounted lip. This eliminates or reduces the need for toe protection structure at the sides of the dock board and enhances manufacturing economy without compromising safety.
