- Durable galvanised steel construction.
- Horizontal, curved, inclined and flow & return conveyors available. Inclined and curved conveyor options up to 45° as standard, 90° as an option.
- Dimple style joints for high mechanical strength and good alignment of of sections.
- 3 piece trough construction allows base to be thicker than the sides providing a longer life.
- Deep flights mean most conveyors are suitable for inclined applications.
- These conveyors are supplied as standard in modular lengths with loose inlets and outlets to allow for faster delivery.

Chain & flight conveyors, in their simplest form, operate by dragging a product along the base of an enclosed trough with a flighted chain, which revolves around a free running tail sprocket and a driven sprocket.
Product enters the conveyor through an inlet usually at the tail and usually exits through an adaptor at the drive end.
There are many variations to the basic machine, some conveyors are designed to be able to run in reverse pushing the product as well as dragging it, some convey along a high tray instead of the base of the trough and some have no base at all, to evenly fill grain stores. Others work on a flow and return principle where product enters the top of the conveyor at any point along its length, is moved by the chain along a high tray until it goes around the tail end shaft and is carried along the base. This method is particularly useful when feeding a line of silos or driers from a single feed.
