ABSTRACT:
A leveler assembly is provided for use within a pit formed in the platform surface of a loading dock. The pit is of conventional construction and includes a recessed horizontal base surface, upright side and rear walls and an open front. The assembly includes a stationary frame mounted within the pit and having an upright section disposed adjacent the pit rear wall and a forwardly extending section mounted on the pit base surface; the latter section effects segregation of the base surface into large contiguous areas, on which debris accumulates, each area being defined in part by the pit open front. A deck member is provided having a rear edge portion thereof hingedly connected to the upright frame section. The deck member, when not in use, normally assumes a neutral position whereby the exposed surface thereof is coplanar with the dock platform surface so as to allow cross-traffic to safely pass thereover. When the deck member assumes a predetermined raised position, the pit base surface areas are accessible and the accumulated debris removable therefrom through the pit open front.
