Pushback Rack
Loads are supported on an incline to enable gravity-based movement of the loads within the rack via roller conveyor. Used to provide highly accessible pallet storage.
Provides LIFO storage in each lane: Loaded and unloaded at the lower end and closed at the higher end.
Adv: Can be used to enable deep-reach storage without the need for extended reach mechanisms for loading/unloading
Disadv: Rack investment costs are greater than for double-deep racks
Maximum depth is 5 loads
