HOW PUSH BACK RACK WORKS
The Push Back rack system has many benefits because of the multiple carts and the highly engineered nesting manner in which those carts glide into position. Simple push back rack applications that are 2-3 pallets deep operate in the same manner as a 6-deep installation.
The system is a LIFO system in which forklift operators never enter the rack. Pallets rest on carts that are moved to the picking position on stainless steel wheels by gravity. Push back rack can be located against a wall for a single-sided system or in a center aisle for a double sided system.
The carts nest on top of each other and slide back one pallet position when a new pallet is added. Each pallet has its own cart and the last pallet will simply rest on rails running the depth of the bay. When the front pallet is removed, the next pallet slides forward to the picking position.
Carts use minimal vertical space within the bay because they nest together and flow forward. Even a 6-deep Push Back rack cart stack uses only 6-1/4″ vertical bay height. This low profile leaves plenty of storage area for pallets.
Special carts can be developed for unstable or damaged pallets and push back racking carts can be color coded so operators can how many pallets are in the bay when it is densely loaded.
It may only seem complex as Push Back Rack is a very versatile and automatically functioning system engineered before it arrives on your site.
