SK3600 Pushback Rack

SK3600® Pushback Rack is a high density storage system that allows you to store pallets 2 to 5 deep while retaining easy access to a variety of different SKUs. Each level or lane is independently accessible and allows up to 90% more product storage than selective rack systems. To load, pallets are placed by forklift on nested carts riding on inclined rails. Each pallet is then pushed back by subsequent pallet loading, exposing the next cart. For unloading, the front pallet is removed, allowing the other carts to roll gently to the front. Unlike other rack systems such as drive-in, each level is independently accessible. With high density storage systems, fewer aisles and forklifts are needed.

System integration is achieved because Steel King manufactures both the cart system and racking, and heavy duty components provide capacities of up to 3,000 pounds per cart. These heavy duty components include:


SK3600® Pushback rack is designed with 55,000 psi high strength steel and can be custom designed for your specific pallet.

Bed Rails

The bed rail is a one-piece welded construction with easy drop-in installation.


Heavy, four-sided carts provide a large target area for loading and unloading. The interlocking cart configuration alleviates jamming and damage. The advantage of storing in carts is that they can accommodate non-standard pallet sizes. You can also color code them for ‘inventory at a glance’. Optional cart accessories include pallet supports for weak pallets or wire decks.


There are four chrome-plated hardened steel wheels per cart with dust and debris resistant bearings.


A highly durable, powder coat paint finish on the SK3600 Pushback Rack offers better gloss, hardness and adhesion than typical enamel paints for greater resistance to fork truck impact, solvents and corrosion, and it’s environmentally friendly.

The SK3600® Pushback racking system is ideal for Last In, First Out inventory.


Product Features

Top cart of any depth pushback comes with a center stop restricting the pallet from hanging over the rear of the cart. Acts as a holding stop not allowing pallets placed after the 1st pallet to push this 1st pallet off the cart.
A stop plate on the rear of the pushback lane stops carts from being pushed off the rear of the system. 
Interlocking tabs between carts. When pushing the top cart back it comes in contact with the lower cart, moving the cart indicating that the next pallet can be placed on the cart. When unloading the lower cart comes in contact pulling the top cart forward.
Hold down angle. Pallets at times can form onto the cart when placed for long periods of time. When unloading, the pallet may lift the cart up, this angle will not allow the cart to be lifted with the pallet.
Full width angles welded to the bottom of the lane to maintain spacing between rails. The angles rest on top and vertically against the beams to eliminate twisting and offer a tight fit.
Pushback rails are bolted to the front beam, through prepunched holes which are designed specifically to the system. Two extra holes in the center of the rail on the beam are supplied for optional add on weak pallet rail support or pallet stop. If a pallet changes and requires one or the other, a quick bolt in solution is in place in lieu of field drilling or new components for existing parts.
