Special channels with wheeled conveyors or rollers sloping at approx 4degrees are integrated into one sub-frame of the P90 racking system. This system is sometimes known as dynamic pallet racking.
One after the other, up to ten pallets can be pushed into these channels and once a pallet is picked from the pick face, the rest roll forward automatically under a controlled speed. Individual pallets further back in the rack cannot be accessed directly.
Speedlock P90 Push Back racking can also be used to provide additional storage space in otherwise unusable areas such as above cross-aisles or around dock-levelers. When fully utilised, very high occupancy rates can be achieved, compared to drive-in racking or block-stacking.
Dexion Push Back - Rollers
Available in depths of up to 10 pallets and suitable for heights of up to 12m, the great strengths of Push Back conveyor racking are;
Pallets are stored on the wheeled/roller conveyors and each new pallet pushes the previously stored pallet back into the channel. Loading and unloading only takes place at the racking front so that forklift truck movements and cycle times are minimised.
Due to the sloping wheel/roler conveyors the rear pallets always arrive at the racking front after the unloading of the foremost pallet.
