Frequently Asked Questions

Carton Flow

How quickly can I get a carton flow solution installed?
All UNEX products are engineered-to-order and lead time depends on the size and complexity of your order. However, lead times for our SpanTrack solution typically range from 5 to 12 weeks on average.

How is UNEX carton flow better or different than the competition or what we already have?
There are several key differentiators that make SpanTrack the leading carton flow solution. Here are the top 5 reasons why SpanTrack is better than other carton flow solutions:

  1. SpanTrack carton flow solutions provide the most surface contact so weight is distributed evenly to optimize product flow and eliminate hang-ups on the track.
  2. Shelf Track carton flow systems provide up to 300% more product contact compared to plastic wheel rails.
  3. UNEX carton flow solutions increase throughput up to 150% compared to picking from pallets.
  4. SpanTrack and Shelf Track’s patented design easily drops into existing structures with very little effort.
  5. UNEX carton flow solutions are backed by an industry-leading 7-year warranty.

When should I use carton flow rollers and when should I use wheel beds?
If your SKU locations vary in size and tend to change often, wheel beds (SpanTrack Wheel Bed) are recommended for maximum flexibility left-to-right for re-slotting. Dedicated lanes (SpanTrack Lane) are recommended for fixed or predictable SKU locations.

Why should I use steel carton flow rollers as opposed to aluminum? What is the cost difference?
Steel rollers are more durable than aluminum rollers and have a low slope needed for long runs. Steel rollers are more expensive but they are built to withstand difficult workflows and are backed by a 7-year warranty.

Can SpanTrack be relocated after installation?
Yes, SpanTrack easily drops into existing pallet racks and can easily be relocated to other areas or facilities as needed.

High-Density Storage

How much does a SpeedCell high-density storage system cost?
To give you an idea, SpeedCell costs the same or less per SKU stored compared to static shelving, for example. Pricing varies depending on your space and requirements for your specific application. The best and fastest way to obtain pricing is to use our SpeedCell product configurator. We will send your design straight to your inbox and one of our Space Optimization Specialists can work with you to refine the solution to meet your unique needs.

What is the most commonly used cell size?
Product size can be variable and operations need to accommodate SKUs of all sizes, but that’s hard to do with a one-size-fits-all approach! Thus, after analyzing millions of SKUs, we’ve discovered that 12” x 12” is the most common size for most industries.

Can I use Pick-to-Light, RFID, or scanners with SpeedCell?
Yes, pick-to-light, RFID, and scanners are all compatible with UNEX SpeedCell.

Do I have to buy special racks for SpeedCell?
Nope! Special racks are not required for UNEX SpeedCell. If you have existing pallet rack, you are ready to install SpeedCell. SpeedCell can be suspended within selective rack or wide-span rack systems and fits any type of beam; box, structural, or step, as well as pick modules and mezzanines.

How do I access the back row on a SpeedCell unit?
Each row of SpeedCell has one less column, easily allowing pickers to access the back rows.

Where is SpeedCell made?
SpeedCell is manufactured and assembled in North America.

Flow Racks

How does FlowCell compare in price to other flow racks like pipe and joint or aluminum extrusions?
Due to its extreme flexibility and modularity, there are thousands of FlowCell combinations that can be engineered to create the ideal solution for your specific needs. This makes it very difficult to provide specific pricing! The average price of our FlowCell flow racks is around $1,000, but to get the most accurate pricing, we recommend designing your solution using our FlowCell configurator. We will send your design straight to your inbox and one of our Space Optimization Specialists can work with you to refine the solution to meet your unique needs.

What is the capacity of a FlowCell unit?
All FlowCell posts are rated at 10,000 pounds. Mobile FlowCell units are rated at 3,000 pounds maximum (750 lbs. per caster). We recommend taking into account the weight of the tracks and structure when calculating total loads.

Why should I use FlowCell over pipe and joint or aluminum extrusions, or installing carton flow into my existing pallet rack?
While it may make sense for you to install carton flow into your existing pallet rack for certain applications, FlowCell may make more sense if you’re looking for a modular solution that offers more flexibility and allows for frequent process changes. Here are our top 4 reasons to choose FlowCell over pipe and joint or aluminum extrusions:

  1. FlowCell is much faster to install (30 to 60 minutes per unit).
  2. Pipe and joint systems are not as durable. With FlowCell, you don’t have to worry about constantly replacing broken joints.
  3. UNEX offers best-in-class flow with SpanTrack, The Original Carton Flow Track.
  4. FlowCell is a total solution that is tailor-made to meet your specific requirements.Other solutions are sold as more of an “off-the-shelf” kit and because of this, customers end up purchasing parts they don’t really need. Another downside to this approach is that customers don’t necessarily get the support they need to create solutions that are engineered specifically for their unique applications. Our team of experts will work with you to ensure you are designing a FlowCell solution that will not only meet your immediate needs, but will also allow for maximum flexibility to adapt to process changes over time.

Can I design my own FlowCell unit?
Yes! You can configure FlowCell units using our UNEX FlowCell Configurator. The configurator tool allows you to design your own solution that will meet your specific requirements. You can start from scratch or choose from popular configurations. We will send a 3D drawing of your design straight to your inbox and a Space Optimization Specialist will reach out to provide you with a quote.

What type of tracks work with FlowCell?
Virtually any type of track is compatible with FlowCell. We recommend using our SpanTrack carton flow rollers or SpanTrack wheel beds. UNEX Cell Track (S5) is specifically designed for use with FlowCell. The track features an integrated hanger/impact/label holder on the charge end, and stop/label holder on the discharge end. UNEX Cell Track for trays (S6) is also available. High Profile, Deck, Knuckle and gravity may also be used.

Are there any general building requirements for FlowCell units?
UNEX prefers that most FlowCell units contain a minimum of two (2) beams between each connection, regardless of number of levels. When including high profile tracks, we recommend the depth of the structure be at least twice the length of the high profile overhang, to prevent tipping.

What gauge steel are FlowCell structures made of?
FlowCell beams 60″ and longer are constructed from 12 gauge steel tubing. FlowCell beams under 60″ are constructed from 14 gauge steel tubing. All FlowCell posts are manufactured from 12 gauge steel tubing.

How can I change sizes without scrapping my entire FlowCell unit?
There is no need to scrap your entire FlowCell unit to make size changes! You can purchase additional posts and beams to easily accommodate any size changes.

What are the benefits of Roller Rack?
Pre-engineered gravity flow racks are proven to speed pick rates, increase space utilization, and ensure FIFO rotation. SKU storage is up to 7 times more dense per bay than pallet position storage, which means up to 80% less travel time for pickers. Roller Rack is ideal for fulfillment, manufacturing, and retail operations where carton flow is required and there is no need to store pallets above the rack.

Can I buy individual components to build my own flow racks?
Yes, you can buy individual components to build your own flow racks. However, we recommend using our FlowCell product configurator so you can ensure you are designing units that will be effective for your unique application. Our team will engineer your FlowCell to order. This way, you’re getting exactly what you need without overpaying for parts you won’t use. All of the engineering that goes into creating your tailor-made solution is free, so we encourage customers to take advantage of this!

Where is FlowCell made?
FlowCell is manufactured and assembled in North America.

What is your standard warranty on Gravity Conveyor?
UNEX warranty on Gravity Conveyors is 2 years.

When should I use a skatewheel conveyor?
Skatewheel Gravity Conveyor is ideally suited to convey lightweight packages and where operations require portable or temporary conveyor lines such as warehousing or shipping areas. Here are the top 3 reasons why you may want to choose skatewheel conveyor for your application:

  1. Skatewheel conveyors require less pitch or angle to transport product.
  2. Empty boxes and very light loads travel better because the force required to start several wheels in motion is less than a full-width roller.
  3. Product tracking is better on skatewheel conveyors, especially on curves, as the differential action of the individual wheels allows the product to maintain its original position on the conveyor.

Are there items that cannot be conveyed on a skatewheel conveyor?
Yes, containers with ring-banded bottoms, drums with chimes, most bagged items, and cartons with flimsy or soft bottoms cannot be handled on a skatewheel conveyor.

What are some examples of roller conveyor uses?
Gravity roller is an almost universal answer when it comes to handling products with a smooth, flat bottom. Gravity rollers can be used in flat (level) lines with the product being pushed manually or set at a decline, allowing the load to move forward by gravity. Gravity rollers are also well-suited for order picking applications – both for dynamic storage and the pick conveyor used along the front of the rack.

Can you provide a portable conveyor?
Yes, UNEX makes both skatewheel and 1 ⅜” diameter roller in an aluminum construction. Both the frames and wheels or rollers are aluminum which is lightweight, making them easy to set up and takedown. Portable tripod supports are used to allow for quick setup – the conveyor cross members nest into the top of the support and height adjustments require no tools. This makes them ideal for setting up temporary lines for loading dock applications.

Where is UNEX Gravity Conveyor made?
UNEX Gravity Conveyor solutions are made to order in our Lakewood, NJ facility.
