Upper carrying troughing | Highcon

Overview

Upper carrying troughing belt conveyor idlers are crucial for supporting the sections of the belt where material is loaded and transported. These idlers come in two basic configurations: a flat design with a single horizontal roller supported by fixed brackets, and a troughed structure with two or three rollers supported within a frame. The troughed design is especially effective in bulk handling applications, as it allows for greater material capacity at the same belt width and speed. Three-roller upper carrying troughing idlers are typically used for unidirectional belts, with side rollers slightly inclined for self-centering belt tracking. For reversible belts, the R version without this inclination is recommended. Selecting the appropriate rollers is essential during the design phase to ensure compatibility with belt width, speed, material characteristics, and environmental conditions. Additionally, transoms and pitch must be carefully calculated to provide adequate support for the material being handled.
