Push back racking is one form of ‘live’ or dynamic storage.
This solution can be cart or Roller in design and based on last-in, first-out, (LIFO).
Where space is at a premium, but a high pallet count is vital, the push back racking solution can greatly increase the number of pallets stored.
The cart system can provide an economical solution for 2 to 4 pallets deep, where the roller system can go between 2-9 pallets deep.
Other benefits to using drive-in pallet racking are that you can use conventional forklift trucks, so reducing costs.
