Dock Plates vs Dock Boards vs Dock Levelers: Buyer's Guide
Dock plates, dock boards or dock levelers? Choose loading dock equipment by height difference, load type and traffic, and learn what to measure first.
Dock plates are light, portable bridges for small gaps and manual equipment like hand trucks and pallet jacks. Dock boards are heavier portable bridges built for larger height differences and, when rated for it, powered equipment such as forklifts. Dock levelers are permanent installations that adjust to each trailer and are the usual choice for docks with frequent forklift traffic.
The right choice depends on the height difference, what crosses it, how often, and whether the equipment has to move between doors. Below is each option, plus what to measure before you ask for a quote.
A note on names
Manufacturers do not all use these terms the same way, so do not buy by name. Buy by rated capacity, usable length and width, and the height difference it is designed to bridge, and confirm each with the manufacturer’s documentation.
Dock plates: small gaps, manual equipment
A dock plate is usually a lightweight aluminum or steel plate that spans the gap between the dock and the trailer bed when the two are close to level. Locking legs or pins drop into the gap at the dock edge to keep the plate from sliding.
Dock plates make sense when:
- The trailer bed sits close to dock height on most deliveries.
- The traffic is hand trucks, carts and manual pallet jacks.
- One person needs to place and remove the plate without a forklift.
They are not meant for forklifts unless the manufacturer rates that specific plate for it.
Dock boards: bigger gaps, heavier loads
A dock board is a heavier-duty bridge, typically with raised side curbs to help keep wheels on the board. It covers longer spans and larger height differences than a plate, and many are built for forklift traffic. Larger boards often have forklift loops or pockets so they can be moved without lifting by hand.
Dock boards make sense when:
- Trailer heights vary more from one delivery to the next.
- Forklifts or loaded electric pallet jacks need to cross.
- You need a portable solution and do not have, or cannot install, a built-in leveler.
When sizing a board for a forklift, count the forklift plus its heaviest load, not just the load, and confirm the rating with the manufacturer.
Dock levelers: built in for busy docks
A dock leveler is a permanent ramp installed at the dock door. It raises or lowers to meet each trailer, then extends a lip onto the trailer bed. On docks with steady forklift traffic, levelers remove the handling that portable plates and boards require.
Pit levelers
Pit levelers sit in a recessed pit in the dock floor. They come in mechanical, hydraulic and air-powered versions and handle the widest range of trailer heights in this guide. Adding one to an existing building usually means construction work, so they are most often specified for new docks or renovations.
Edge-of-dock levelers
Edge-of-dock levelers mount to the dock face with no pit. They handle a smaller height range than a pit leveler but cost less and install more easily, making them a common upgrade where portable plates are slowing things down.
Yard ramps, briefly
A yard ramp, or mobile loading ramp, lets a forklift drive from ground level into a trailer when you have no dock, or need a temporary extra door.
Side-by-side comparison
| Dock plate | Dock board | Edge-of-dock leveler | Pit leveler | |
|---|---|---|---|---|
| Height difference | Small | Small to moderate | Small | Widest range |
| Typical equipment | Hand trucks, carts, manual pallet jacks | Pallet jacks, forklifts (if rated) | Pallet jacks, forklifts (if rated) | Forklifts, high-volume traffic |
| Frequency | Occasional | Occasional to moderate | Moderate to frequent | Frequent |
| Portability | Carried by hand | Moved by hand or forklift | Fixed at one door | Fixed at one door |
| Installation | None | None | Mounted to dock face | Requires a pit |
How to choose: four questions
1. How big is the height difference?
Measure the trailers you actually receive. Small, consistent differences point to plates or edge-of-dock levelers; large or variable ones point to dock boards or pit levelers.
2. What crosses it?
A hand truck with a few cases is very different from a loaded forklift. The heaviest equipment that will cross, with its heaviest load, drives the rating you need.
3. How often?
Occasional deliveries can be handled with a portable plate or board. Many trailers a day at the same door usually justify a leveler.
4. Does it need to move?
If one plate or board needs to serve several doors, portability matters. If each door is busy on its own, built-in levelers keep each door ready.
For safety, check the manufacturer’s documentation and your safety requirements, including trailer restraint and wheel chocks where they apply. Our team can help you obtain manufacturer documentation.
Measure your dock before you ask for a quote
A tape measure and a few notes save a lot of back-and-forth:
- Dock height: from the ground where trailers park to the top of the dock floor, at each door you want to equip.
- Trailer bed heights: the lowest and highest you see, from box trucks and step vans to standard trailers, refrigerated units and containers on chassis. Trailers can settle as they are loaded, so note that too.
- Gap at the dock face: the distance from the dock edge to the trailer when it is backed against the bumpers.
- Door and trailer width: to size the usable width of a plate, board or leveler.
- Existing setup: whether there is a pit, an old leveler, bumpers, or nothing at all.

How to get the right quote
Send us:
- Dock height vs the trailer bed range you see: your dock height plus the lowest and highest trailer beds.
- Trailer types: box trucks, step vans, standard trailers, refrigerated units, containers or flatbeds.
- Equipment crossing: hand truck, pallet jack or forklift, with the heaviest combined weight of equipment and load.
- Frequency: roughly how many trailers per day or week, and how many doors.
- Photos: of the dock face, the door and any existing equipment.
FAQ
What is the difference between a dock plate and a dock board?
In most catalogs, a dock plate is lighter and meant for small gaps and manual equipment, while a dock board is heavier, often has side curbs, and handles larger gaps and, when rated, forklifts. Names vary, so compare by rated capacity and dimensions.
Can a forklift drive over a dock plate?
Only if the manufacturer rates that specific plate for forklift traffic and the combined weight of the forklift and its load. Many lightweight plates are meant for hand trucks and pallet jacks only.
Do I need a dock leveler, or will a dock board work?
A dock board works well for occasional or moderate traffic and when one bridge serves several doors. If forklifts cross the same door many times a day, a leveler usually makes more sense.
What is an edge-of-dock leveler?
It is a leveler mounted to the face of the dock with no pit. It covers a smaller height range than a pit leveler and is a common upgrade from portable plates.
