What is a Copperloy Dock Leveler?

An edge of dock leveler (EOD) is a great solution for a lower budget when bridging the gap between your dock and a truck bed. They mount directly to the dock face and provide a working range to extend above or below the dock. In contrast to a dock board, EODs are attached to the loading dock. A dock leveler is an ideal solution for trucks backing up to a dock. By simply pulling the levelers handle, it will lift over the top truck height for easy positioning.

The Copperloy edge of dock leveler is an economical solution for applications that do not support the installation of a pit mount lift table or loading docks that serve standard trailer heights. Edge-of-dock levelers are easy to operate and represent an ergonomic and safer alternative to dock plates.

What’s the Use?

Dock levelers allow our customers to safely and efficiently unload otherwise difficult freight handling tasks. Use these levelers to correct the height difference between trucks and loading platforms. This helpful tool compensates for 5″ above or below dock levels. To top it off, these heavy-duty products handle capacities of 15,000-30,000 lbs.


Dock Leveler | Top Benefits

Copperloy levelers are easy to operate. Whether you’re using the handle or the wall-mounted push button, the leveler will fully extend to the height of the trailer bed. This dock leveling tool allows for safe freight handling.

Dock levelers are ideal for limited dock space or when the working range of a full-size, pit-style edge of dock leveler is not necessary. Each leveler is available with hydraulic or mechanical activation (lift).


Made in the USA, our edge of dock leveler’s design is engineered using a three-dimensional engineering software package. Then, we use our unparalleled steel fabrication skills to provide customers with the highest level of performance.


Our exclusive lift mechanism and spring assembly set the board in place with one-quarter the effort needed to operate conventional edge of dock levelers.


All the benefits of the mechanical system are also available in our hydraulic material handling dock leveler models.


The Copperloy edge of dock leveler easily mounts to the face of almost any dock. Transition plates and approach ramps are also available.


Every Copperloy edge of dock leveler is equipped with a safety maintenance strut to secure the unit while performing routine maintenance.


Maintenance is reduced to simple lubrication of hinges which come equipped with grease fittings.

Dock Leveler Installation

For proper dock level installation, it is absolutely necessary to review the edge-of-dock manual. In turn, users are able to take essential precautions.

To get started, the installer needs to evaluate the health of the dock area and make any necessary repairs. All anchors in use must have a minimum strength in shear of 10,000 lbs force and a minimum of 6,000 lb pullout strength in solid concrete. Also, the dock leveler needs to be in compliance with all local codes.

For additional helpful tips of proper installation, consult with a member of our Copperloy team. Plus, check out the video below and the owners manual!
