The accumulation roller conveyor is used as a zero-pressure conveyor for transport units. Rollers are stopped specifically to avoid collision when one transport unit comes to a standstill.

Accumulation roller conveyors are ideally used in areas where there is risk of jams and in buffer zones. Accumulation roller conveyors may be driven by a powered belt or by motor rollers SMR.

The accumulation roller conveyor is used as a zero-pressure conveyor for transport units. According to its functional principle, single conveyor segments are disconnected if the next segment is occupied by a transport unit.

Each segment is controlled by light sensors mounted between the rollers.
