PUSH BACK RACK SYSTEMS
Push Back rack systems are available in structural or roll-formed frames. Push Back rack systems work by placing pallet loads on a series of nesting carts fed forward by gravity on rigid structural steel rails.
As a pallet is loaded from the front, it pushes the pallet behind it back one position. The front pallet is removed when unloading and the rear pallets automatically come forward to the front picking position. This allows for easily accessible Last-In-First-Out (LIFO) inventory management. Operators can store product from 2-5 pallets deep, with front-only loading from a single aisle.
Push Back Rack offers more versatile storage than Drive-In rack because each lane flows independently and vertical storage operates separately from lanes below. Multiple pick facings for a variety of SKUs can be stored and retrieved without disturbing other product above or below in a single-lane or double-lane format.
Flow is achieved by gravity moving the push back rack carts along the inclined rails which are adjustable vertically to control pitch. Welded structural steel carts make installation easy and four fully-sealed and lubricated wheels per cart provide years of durable flow. Each cart can be designed to hold up to 3,000 lbs.
Lift truck drivers never enter the rack. The first pallet rests on the top cart and the second pallet pushes that pallet back to rest on the second cart.
Additional pallets will rest on the nested carts below and the final pallet rests on the sturdy structural steel rails. As pallets are removed, each position behind flows forward gently until all product is finally brought to rest by rubber bumpers at the front of the system.
UNARCO can help design carts for special non-standard pallet support or products with typically weak pallets. For more photos of Push Back Rack view UNARCO Push Back Rack Photo Gallery.
