Worldwide Conveyors are manufacturers and suppliers of Idlers and Idler Frames.

There are two categories of Idlers, basically Carrying Idlers and Return Idlers . However within these two categories there are a number of different Idler Sets which suit various applications. They are specifically designed to suit those operations so as to minimize friction, increase material carry and alleviate unnecessary stress on the Conveyor Belt.

Troughing Idlers are found on the carrying-side of the Conveyor, and continue through the whole length of the Conveyor at designed center distances to each other. All Idler sets are the same and the distance from each other and the trough angle used are designed around friction factors, material conveyed and tonnage requirements.

Garland Idlers are used predominantly on Yard Conveyors, Underground Conveyors, Mobile Conveyors and Dump Conveyors etc. Where the alignment of the Conveyor Structure may not be completely correct due to the continuous shifting of the Conveyor, or the uneven ground onto which the Conveyor Structure is placed. The Garland Idler design is more adaptable to various conditions, due to its chain-like design which allows the Belt center line and Idler centers to move relative to the supporting frame.

These Idlers are manufactured to Absorb Impact and Protect the belt from the Impact of the Material loading onto the belt.

Where Return Idler Sets comprises of two rolls, a Support Frame is required which supports the Idler Pair and attaches the Idlers to the Conveyor Frame. This 2-roll design forms the Return Belt into a 'V' Trough and these Return Idler sets are referred to as 'V' Return Idlers. The Trough angle of the 'V' Return Idler is usually 10 degrees and this feature has been developed to assist with Belt training along the Return Strand. In addition to the fixed base frames for Return Idlers, Garland-Type Return Idlers are also available. Which like their equivalent Troughing Idlers are more tolerant of Conveyor Structure misalignment.

In spite of the correct alignment of a Conveyor Structure and Belt Splice, it is a common occurrence for a belt to want to misalign at times. Mainly as a result of incorrect material loading (off centre) or in cases where a Conveyor is mounted onto a Mobile Stacker or Reclaimer where the fall across the boom causes the belt to move to one side. In cases where the belt misaligns, severe damage can be done to the belt should the belt rub against a Fixed Structure, the Head Chute or Conveyor Stringers
