A dock leveler (also known as dock lift plate) is a metal bridge that covers the gap between the dock floor and the transport vehicle, protecting your material and your staff during the loading/unloading.

1. What Are the Different Types of Dock Levelers? 

Dock levelers (also known as dock plates) come in a variety of types.  

1.  Pit Levelers: 

Pit-style dock levelers are found in a recessed concrete opening in a building’s
concrete at the dock door. The main sub-categories of pit levelers are:

1.1 Mechanical Dock Leveler (also known as Mechanical Pit Leveler) 
1.2 Hydraulic Dock Leveler (also known as Hydraulic Pit Leveler)
1.3 Air-Powered Dock Leveler (also known as Air Pit Leveler)

2.
Edge-of-Dock Levelers (EOD)

The EOD are an upgrade from portable dock boards, but still a less expensive option compared to a pit or vertical dock leveler.  These have a limited vertical operating range and is geared toward applications where the transport vehicle bed is
at, or very near, the floor level of the building (dock level).

3. Vertical Storing Hydraulic Dock Leveler

This dock leveler is stored in a vertical position, allowing you to store the leveler inside the building. Ideal for a building where environmental control is needed.

4. Rail Dock Leveler

These levelers involve a variation on the vertical leveler and are used to service rail cars. They are usually mounted on a sliding rail that allows them to move
horizontally along the rail track.

2. How to Choose a Dock Leveler/Dock Plate? 

There are many different dock levelers to choose from. We suggest keeping in mind the following considerations while you're making your decision:

- The volume of traffic: How frequently will you use the ramp?
- The total gross weight of your loads: What is the maximum load you expect the leveler to handle? Make sure you include both the weight of the lift truck and cargo when determining the load
- The difference in height between the trailer & the dock: What range of trailer deck heights do you need to accommodate? 

- What's the operating environment like? In refrigerated warehouse applications or facilities located in cold climates, insulation requirements will dictate the style of dock leveler that you'll need
- Anticipate future needs: Selecting a dock ramp to meet your future needs avoids the costs of having to replace an obsolete leveler in the future.

3. Manual vs Powered Dock Levelers

- Manual dock levelers (mechanical levelers) are well suited for most low-traffic docks. These require no electrical connection and the simple operating principles will provide years of trouble-free operation. It's important to mention that these mechanical units will have much higher maintenance costs in the long run.

- Powered dock levelers
(hydraulic levelers) are well suited for higher volume docks. The extra cost of a powered leveler is easily justified when you consider the benefits to dock productivity, worker safety, and the lower long-run maintenance costs.

4. What Are the Available Sizes and Capacities of the Dock Levelers?

Dock levelers are designed to work at various heights and accommodate various weights. For example, if you expect light ramp loads (less than 20,000 lbs.) and little variation in trailer heights (within a 3” range above or below dock height), a mechanical or a hydraulic edge-of-dock leveler (EOD) could be a good choice.

If you load/unload from a variety of trucks and/or trailers, or handle heavy cargo, you will appreciate the extra functionality of a pit-style dock leveler (also known as recessed style dock levelers). This is the most common type of dock leveler because it has a greater operating range, load range, and life expectancy. Pit levelers require concrete modification to the loading dock to accommodate the leveler, but the recessed pit and ramp leveling mechanism provide easy alignment with a range of trailer heights. 

Dock plates/dock levelers come in different sizes, from 6’ to 7’ wide and from 6’ to 12’ long). The most common dock leveler capacity requests are from 25K to 35K, but at Loading Dock, Inc., we have up to 100K available.


5. Accessories to Increase Safety in the Dock Area

At Loading Dock, Inc., we suggest to accompanied your leveler systems with truck restraints, and light communication systems to help prevent accidents caused by premature trailer departure.
