ABSTRACT:
A device is shown that is adapted to be used with heavy portable dockboards or dockplates to raise a corner or edge thereof so that the forks of a forktruck can be pushed under the dockboard structure that is to be lifted and transported to another location. A leverage system is permanently mounted on one or more corners of the dockboard or the like, the system being operative to easily raise at least one corner of the board high enough to permit the forks of the forktruck to be slid under the board.
