Frequently Asked Questions

We’ve compiled a list of our more commonly asked questions below for quick reference. Of course, if you don’t find an answer here, just contact us and we’ll be happy to chat.

Oh, and you should see the list of the less common questions we get. The quick answers are:

  1. While it’s possible to get Grandma’s chair upstairs with our systems, builds are already in place that are designed for such a purpose that won’t get us sued.
  2. That is correct; we do have the second-largest Popeye memorabilia collection in Chester, IL.
  3. No, you can’t ride that.

It is a fairly common thought that you always need a conveyor that is wider than your product; but that actually isn’t always the case. You may be able to move your parts, boxes, cartons, and cases on conveyors that are significantly narrower than your product and it can actually have some benefits!

Let’s not dance around it: The main benefit is usually cost. A thinner conveyor is generally a more cost effective solution. And we love to think thin!

End-to-end transfers can be much smoother when the conveyor is thinner than your product. Mounting rails or slide plates to the side of your drive or idler can prevent your product from dipping into the gap between radiuses. This avoids products being stuck or defaced by hesitation in the transfer between the two conveyors. A smoother process means a cleaner product.

Also, if you add some automatic, adjustable guiderail, you can haul multiple sizes of product on a narrow conveyor, just like you can with a wider model.

Don’t assume that you need a wider conveying surface without considering a thinner possibility!

It seems like every trade show that we do someone asks us about elevating solutions. There are so many great ways of inclining and declining products out there that it can get a little confusing, not to mention overwhelming, trying to figure out what the best solution is (especially when you don’t live and breathe material handling day-in and day-out).

We in the conveyor industry tend to embrace our jargon with a passion which only makes things worse. It can be awfully confusing to try and translate what exactly someone means when they say “Alpine” or “Blanket Conveyor.” We’ve tried to use layman’s terms, but where’s the fun in that?

So, without further ado and with a little insight into their names, here are seven elevating options from Flex-Line Automation!

Incline/decline conveyors are the most basic elevation changing option. They usually use friction chain, friction belt, cleated chain, cleated belt, roller cleats or small elevation changes over a long run in order to get a product moving up or down in a controlled manner. They are great when you have a lot of room or don’t need drastic height changes. The roller cleat style can even feed product in between the cleats with no additional automation!

Alpine conveyors are what immediately springs to my mind when I think of FlexLink conveyor choices. I’m not even going to pretend that they aren’t my personal favorite. We strapped a camera to a pallet moving through one of these once. It was awesome. You can check it out here.

These conveyors are named after their shape, which is reminiscent of a switchback trail up and down a mountain slope. They are especially fantastic for accumulation applications where you have a limited amount of floor space available. They are a great way to utilize your vertical space.

Spiral conveyors are another great choice for elevation changes. Again, the name says it all. These conveyors spiral product up or down with a small footprint. You don’t get as much accumulation as you can with an Alpine, but a thirty foot tall spiral can carry a bunch of boxes up to a mezzanine quickly and efficiently!

Wedge conveyors, also known as side grip conveyors, are another classic choice. While they don’t provide much by way of accumulation, their ability to pick up individual products from a horizontal belt and transfer them vertically at angles up to 90 degrees is incredibly useful and a great space saver. You can even run them at different speeds than your main line as a built-in singulation station. They are also wonderful for vision check and base coding applications.

Blanket conveyors are actually a dual conveyor system. The lower incline belt usually is plain chain, and the top belt usually has friction links or cleats, which lay down over products as they move up the incline, blanketing the product and holding it securely in place as it moves through its elevation change. This is a great option for moving products, especially bagged goods.

This style of conveyor was showcased at Pack Expo in 2014 with what everyone affectionately called the “Drawbridge” conveyor. That particular blanket conveyor uses a section of chain beam to add more weight to the chain and helps to singulate product. Another option under the Blanket umbrella is actually to sandwich products between two running conveyors, which is a great way to move heavier items.

Hold down rails are often used with incline conveyors in order to provide a little bit of down pressure on products to keep them in line as they move. Hold downs can be fixed, adjustable, or even made of rollers, depending on your exact needs. The use of a hold down rail and cleated chain is a very economical way of elevating within a small footprint.

Elevators/lift stations work when none of the other options are a good fit. They can be electric or pneumatic, and provide rapid ascent and descent in very tight quarters. They are especially useful with moving pallets, trays, or larger, unwieldy products.

I hope that this has helped you to see some of the wide variety of options we have for elevating/lowerating your products! Would you like more information on any of these options? Feel free to give us a ring and take advantage of our experienced engineering department!

Or you can call just to talk to me about how cool Alpines are. That works, too.

Replacing or repairing chain is usually done at the drive where catenary sag is present. It can also be done in adaptable sections if you are using guided drives, but you can also take the side plates off of the idler if the drive is guarded or guided and replace the chain there.

It is easiest to check for wear on wear strips in vertical bends. Look for dusting on the outer radius. If the anodizing begins to shine, it is time to replace your wear strip. You can also look for dust accumulating on the outside of your beam. The wear strip is very important to prolong the life of your conveyor. The chain can actually eat through the aluminum chain beam otherwise.
