Edge of Dock Levelers (EOD’s) are used as a cheaper alternative to pit-style levelers, while still providing access from a loading dock to the back of a trailer. Although they are more expensive than a dockboard, they are fixed to the wall & require only a metal bar or hook to activate the lip & provide access to the trailer.
EODs are the solution for any of the following loading dock conditions:
- When the dock area is relatively congested and space in the dock area is limited, because the EOD is mounted to the outside of the dock and is away from traffic during operation and when stored.
- When the trailer heights are within 5 inches above or 5 inches below the dock. Captive fleets (all one size trailer) are ideal for an EOD application.
- When a fixed dock leveler is desired, with a minimum of capital budget.
- When an existing truck dock can be reconstructed to accommodate a fixed leveler.
The installation of an EOD is relatively simple: a weld along the dock edge & expansion bolts on the dock face. It is a NWHS policy that if we are doing an installation, a minimum steel embed of 8” C-Channel is required. If there is not 8” (most docks only have 3” or 4”) a transition plate is required. A transition plate lays flat along the floor of the dock right up against the edge of the loading dock. It is typically 12” safety tread construction & is as wide as the EOD. It is bolted to the floor directly. There are two styles- a flat plate with a beveled leading edge (TP.BEVEL), or a groove is scored into the floor & the leading edge is buried into the floor to prevent pallets from catching on the plate (TP.BEND). See diagrams below.
Customers will be happier in the long run with the bent transition plate scored into their floor. Bevel plates commonly get pallets snagged on the leading edge & over time debris will build up under the plate & cause separation from the floor. The installation of the bent transition plate is more expensive, however.
The most popular widths of an EOD is either 66” wide or 72” wide.
