The Belt Tray Sorter consists of a series of conveyor belts, arranged orthogonally to the direction of the running of the sorter. This enables items to be fed onto the belt tray at a speed adapted to the sorter speed and the angle of induction, permitting items to be fed or discharged optionally to the left or to the right. For the discharging process, the belt moves towards the discharge and the item is guided gently into the destination.
Compared to other cross belt sorters, the BEUMER Belt Tray Sorter incorporates 50 % fewer components, while the distance between the conveyor belts has been reduced to a minimum. The use of belt trays makes it possible to arrange smaller, closely stacked destinations, thus reducing reducing the square footage occupied by the sorter.

Each belt tray is driven by a maintenance-free DC motor. Energy is transmitted to the Belt Tray Sorter without direct contact. This as well as the contactless working linear drive of the whole system contribute to reduction in wear and maintenance. "The contactless energy supply keeps the operating costs low and the modular structure allows for an adaptation of the system to any building situation - and that without any loss in performance" sums up Olivier Prato, President of Beumer SARL in Saint-Ouen l'Aumône.
