Used mainly in the automotive sector but also in other areas, the buffer chains are adopted in continuous conveyors where there are points in which the product, whether it is placed on a skid, a pallet or a frame, or contained inside a crate or a box, can accumulate and form a buffer, while the underlying chains continue to flow.

The common element to all these solutions is the presence of the free upper roller that supports the load and at the same time allows it to remain stationary in the accumulation points, waiting to continue its journey.

The existing single or double chains, with internal or external accumulator rollers, in multiple configurations and sizes, offer a wide choice to designers and users, without precluding the development of new innovations.
