What Customers Are Saying
"In 2018 our company was in a really weird position. We had purchased 2 large expensive conveyors over the last 5 years from 2 different manufacturers (Yes our application is rugged, heavy and has lots of baling wire). Both systems caused non-stop maintenance issues that were becoming very expensive for our company. We were referred to Fluent Conveyors by a local distributor/dealer in our area and from the start, I knew we found the correct manufacturer. Their pre-sales team visited our facility, took the time to listen to our core issues, and allowed our team to become part of the entire design process. I found their team slowing us down to re-validate key dimensions etc to ensure this new system would not only meet our expectations, but help position our capital layout to actually work for us for more than a couple of years. It has been almost 2 years and I can say the Fluent Conveyors team delivered exactly what we expected. No issues, 100% functioning and were are currently exploring adding a brand new system at one of our other facilities in 2020. Thank you for being professional and experts at your craft.

- What makes this roller chain belt heavy duty?
Fluent Conveyors designs these machines specifically for the toughest and most abusive environments. We understand that the real world isn’t clean and it’s not always practical to load heavy materials with little impact. Fluent Conveyors builds the Roller Chain series conveyors and belts out of thick-walled structural steel and formed steel plates. Our engineering department reviews all critical loads and impact zones for each application to ensure the direct forces to the loading zones and belt chain pull have a factor of safety of 1.3 above the application requirements.
We leverage 25-pound rail, ¼" and 3/16” thick formed steel plate throughout the core design with strategically placed gussets, cross members and impact rails to withstand vibrations and impact forces.
- Can this conveyor model be configured with different belt options?
The roller chain conveyor series is a made to order conveyor. We can leverage existing projects to help reduce lead times for your application, but if you have space constraints or an existing pit, we can customize the design to seamlessly match your facility.
On the pre-sales side we get as much data and information on each application to correctly size chain, sprockets, bushing, pins, rollers, belt pans (rubber, hinged steel, apron pan or z pan) etc. as well as to make sure the surface of the roller chain belt has the correct strength and load capacity to exceed your application requirements.
- What type of motor / drive unit is used for this model?
Fluent specs parallel shaft gear reducers and IP55 integral (direct mount) motors. These are standard with 230/460V at 60Hz. Fluent can change this to match your specific requirements whether it be helical bevel gears, a certain manufacturer for continuity or a different power input.
- What is a roller conveyor system?
Roller conveyor systems can be powered by a motor and drive system or through gravity. These conveyors consist of a series of rollers that are closely spaced to each other to distribute the load.
Gravity roller conveyors can be level or declined. The level gravity roller conveyors are used for accumulation and the product can be pushed by hand. The declined conveyors use gravity to move the conveyed product down the slope. These can be very cost-effective solutions for moving boxes and pallets throughout a distribution facility.
Powered roller conveyors use either a series of bands or belts, or gears and chains to turn some or all the rollers. These are called the live rollers. These conveyors can have different segments that are powered separately from each other allowing for accumulation and powered flow. This type of conveyor is extremely flexible in its design and capabilities. Powered roller conveyors are commonly found in locations where there are complex needs for the movement of the conveyed materials.
- When do you replace a drive chain in a conveyor belt?
Similarly to your car, conveyor drive systems need regular maintenance and upkeep to run smoothly for a long time.
One of the main indicators of a worn chain is the wear elongation. If the chain has elongated more than 3% from its original pitch length, then it is necessary to replace the chain. This length can be determined by measuring from one chain pin to the next in a taut part of the chain (a slack segment of chain will not give accurate measurements). Using multiple pitches will increase the accuracy of your measurement. Look up the ANSI standard pitch for your chain (it may be stamped on the side bars) and compare. Chain wear scales are extremely helpful for this measurement.
A tell-tale sign that a chain is worn and elongated is that the chain will be riding high (or up near the tip of the sprocket teeth) on your largest sprockets in the system. If you see this, replace your chain immediately.
If your chain is visibly damaged, bent or rusty it is recommended that you replace it immediately.
