Carton Flow Specification: How to configure Low Profile Span Track

• Browse sizes, prices, configurations - secure online catalog

Low Profile Span Track is designed to fit between your existing pallet rack beams using a series of hangers designed for the exact beam style you have. Since it's designed to retrofit into virtually any pallet rack configuration, Low Profile can be cut to the inch and fit into single or double deep racking for a perfect fit.

How deep (long) should your Span Track be?

To answer this question, you must measure your rack (if you already have it) or find out the critical dimensions if you are ordering rack as well as Span Track. If you're ordering rack from Cisco-Eagle, we'll help you configure the correct sizes in advance.

Unsupported spans of up to 10' are possible, depending on product weights. Low profiled requires precise measurement of rack depth - also known as the Between Beam Dimension:

The Between Beam Dimension represents the level, horizontal distance between the front and rear beams. You should measure the level distance between the innermost part of each beam. You will need to set the discharge elevation later, based on the weight of your cartons.

Setting the Flow Rack Pitch

Pitch requirements vary based on the weight and quality of the load cartons.

Set your front pallet rack beam to the desired discharge elevation. Then, set the rear beam at higher elevation per the table above to achieve good flow. We suggest that you set the first level, check the pitch to be sure it's working, then move on to installing subsequent levels. The best way is to install a shelf at the proper pitch and let it sit 24 hours. Then, remove cartons at the pick face to check resulting flow.

Width - how many tracks can fit on a beam?

Low Profile Span Track comes in 4 widths: 6", 9", 12", and 15". (We offer only 9"and 12"in our online catalog, but 6"and 15"models are just as readily available). These widths are nominal. The actual width is 3/4"wider. So when calculating the number of tracks that can fit onto your beam, take the 3/4" expansion per track into account. Most applications won't require the total left-to-right density of flow tracks, since you can specify track widths to carry cartons wider than the track itself.

Track Width - How wide?

Span-Track provides excellent product tracking. Guide rails are not required. It is an acceptable practice for firm flat carton bottoms to be of greater width than actual track section.

Roller Centers

Cartons with firm flat bottoms will flow properly if supported by a minimum of three rollers. Cartons with poor bottoms or heavier weights may require closer centers to provide proper flow. If you are using cartons of various quality, choose the roller center designed for the lowest quality carton you intend to convey.

Number of Shelves

Typically, the number of shelves is decided by needs. If you're trying to maximize the number of pick positions in a particular area, you'll need to factor in the height of your cartons as well as the necessary room for beam positions at the proper pitch for your product to flow. You'll be limited by overhead storage (the height of the first static rack beam), and by the floor or by the level of the lowest pick face you want to have.
