Conveyor Belt Alignment: Tri-Return Training Idler

Self-adjusting 3-idler design centers conveyor belt automatically, preventing belt damage and spillage due to misalignment.

tri-returnTri-Return Training Idler Misaligned conveyor belts can wear the edge of your belting and damage your conveyor structure. Misalignment is also a major cause of material spillage, which decreases the life of your idlers, increases overhead due to cleanup cost, and is a serious safety issue.

The Tri-Return Training Idler uses a patented concave arrangement of three idler rolls on a center pivot to keep your belt in line. The center roll is horizontal and the two outer rolls are mounted at a descending angle. This roll arrangement allows the trainer to fit the full cup of the belt.

Patented Concave

Idler Design

The Tri-Return’s idler rolls are mounted on a steel frame with a central pivot point and guidlers on either side, enabling the Tri-Return to conform to the natural cup of the belt — contacting the entire width of the belt.

Outperforms Any Other Training Idler

The Tri-Return is unique because it uses 3 idler rolls instead of the usual single roll, allowing the Tri-Return to automatically center your belt. The Tri-Return literally beats other idlers coming and going because it works on reversing belts; most other idlers don’t.
And, where the Tri-Return Training Idler prevents misalignment automatically, other idlers may just complicate your alignment problem:

Manually adjusted trainers just create more work for you. The trainer isn’t doing the job — you are.
Overly complex designs, such as fulcrum and lever action-type trainers, aren’t simple to install and maintain.
“Set and Forget” style trainers can cause problems in the future, because a one-time setting doesn’t allow for changes in your conveyor as it ages (due to belt replacement, idler and pulley failures, and so on).
