The H & B Mining DDR conveyor idlers are designed to facilitate & simplify the removal/replacement of worn or damaged idler rollers whilst the units remain in an “insitu” location under skirted or difficult access areas on conveyor systems.

The H & B Drop Down Retractable Conveyor Idler is designed for use on a conventional mining conveyor system arrangement of a single row of rollers and incorporates a retractable capability which improves access to the central idler roller, enabling easy maintenance of the conveyor. They are manufactured to facilitate site standard impact or carry idler rollers or any other nominated rollers used by the Australian mining industry.

The Drop Down Retractable Conveyor Idler allows for replacement of the wing rollers alone (Procedure A) or the central roller and one or both of the Wing rollers (Procedure B). Idler rollers are replaced by using standard ¾ tonne lever/chain blocks or similar to raise, lower & retract the frame components as required.
