Just like you’re expected to be the material handling knowledge expert for your customers, we want to help fill that role for you.

As a result, we’ve created this toolkit of resources for you to use.  Remember that along with the handy guides, tools and learning resources below, valuable information shows up on our blog very frequently, so check back often

Most of the resources available here are in PDF format and available for download. Of course, we’re always happy to offer additional help if you have a question or a problem.

Interlake-Mecalux Beam Changes

Beginning  on December 1st, 2014, Interlake-Mecalux is manufacturing their beams with a new punch-press formed connection in place of the riveted style they used in the past.

Material Handling Institute Knowledge Resources

MHI Logo

The Material Handling Institute and the Rack Manufacturers Institute both have significant resources available for learning more about rack and other material handling systems and much of it is available online.

Check them out:

RMI Frequently Asked Questions
This link provides excellent information from the manufacturers themselves.  Be sure to scroll to the bottom and check out the links in the gray bar for expanded details.

MHI Fundamentals
Another excellent resource, even though it’s a bit basic.  I’ve started you out on the rack fundamentals page but be sure to explore the other areas as well.  You can learn about everything from AS/RS to Industrial Robots.  Be sure and check out the Glossary too.  It’s a great resource if you run into something you’re not familiar with.

Designing Selective Rack Based on Pallet Sizes

Bay Dimensions ExampleThis chart will help you quickly and easily identify the beam lengths and upright depths you need based on your customer’s pallet sizes.  I included the 10 most common pallet sizes in the U.S.

3D Pallet Rack Identification Guide

3D Rack

There are a lot of different rack manufacturers out there and they all have their own idea of how a beam should connect to a frame. If you’re having trouble identifying a customer’s rack system, these videos should help.

Preliminary Design Help

Let’s face it, every so often everyone occasionally needs help with requests that you haven’t handled before or that you’ve done, but not often enough for it to stick in your brain.  Having a cheat sheet for situations like this can make the job both faster and easier.  To help you get there with requests for systems like cantilever, drive-in rack or pallet flow, you’ll find preliminary design request worksheets that you can download and use for a variety of material handling systems.  Just click on the image to download our PDF “cheat sheet” for that system.  Of course, I’m always happy to help with any questions or problems.

Understanding the Height-to-Depth Ratio for Single Rows

Height to Depth RatioAs you know, there’s a surprising amount of math involved in something that seems as simple as pallet racking.  While everyone in the industry understands that frame capacity is based on vertical beam spacing, the limits on frame height are less well known.

The Rack Manufacturer’s Institute standard  is based upon a six-to-one ratio of height to depth for a single row of pallet rack.  This requirement is in place as a safety measure to prevent the row from tipping over, even when anchored.

The height measurement is from the floor to the highest loaded beam level, not the frame height.  For example, if you have 240″H x 42″D frames with a beam level at the top of the row, 240/42 gives us a ratio of 5.7 to 1, which is within the specification.  However, if you have 288″H x 42″D frames, the highest beam level allowed in a single row is at 252″:  252/42 equals 6 to 1. Placing a beam level above that point may require with uprights oversize base plates, or tying off the single row to the wall, roof structure or cross-aisle to other rack. Each of these solutions add rack stability.

Note that this requirement isn’t tied to the frame or beam capacity at all and only applies to low-seismic areas.  As always, rack that is subject to additional seismic forces require a detailed analysis by a qualified engineer.

 Ridg-U-Rak and Interlake Frame Capacity Charts


As you know, frame capacity varies depending upon the unsupported vertical distance between the beam levels.  Here in one handy place are the capacity charts for the Interlake and Ridg-U-Rak frames we stock.

DAK Knowledge News: Counting Requirements for Warehouse Racking

AbacusFiguring out how much of each piece of equipment you need can be overwhelming when you’re staring at empty space in a warehouse. While it may look daunting, there are some simple rules for getting accurate counts on basic selective rack projects. We took these rules and put them together into a single document for your use.

DAK Knowledge News: The Art of Uprights

DKN Uprights

When aiming to optimize storage and get material off the floor of the warehouse or distribution center, we all know that our material handling solution starts with the upright frame.

Uprights seem like a simple part of the plan—they provide the framework for the beam levels of our storage solution. However, understanding frames and how they help support our material is more complicated than simply being a place to hang our beams.

DAK Knowledge News: How to Select Pallet Rack Uprights

framesChoosing the right upright frames can seem like the easiest decision to make in designing a pallet storage solution. Simply make sure that the depth of the uprights works with the depth of your pallets and that you have enough height to store all the levels you want and you’re done, right?

Well, it’s not quite that simple.

DAK Knowledge News: All About Wire Decking

standard deckingWe all know and use wire decking in our material handling solutions to provide storage for cartons, drums, multiple pallet sizes or in situations where pallet supports just won’t work. In many cases, local fire marshals are beginning to crack down on the use of wooden planking which also leads to the use of wire decking. Improved visibility is also a plus.
