How Push-Back Works
Each lane has inclined rails with nested carts. The forklift pushes each new pallet against the last; pick the front and the stack rolls forward. One aisle, last in, first out.
Sizes and Capacities
| Item | Typical |
|---|---|
| Lane depth (front to back) | 8' 6" to 9' (two 48" pallets plus the cart and stops) |
| Rail slope | 3/8" to 1/2" per foot |
| Pallets per lane per level | 2 |
| Cart capacity | 2,500 to 3,500 lb |
| Levels | 3 to 5 |
| Beam length | 96" commonly holds two lanes of 40"-wide pallets; check the maker's lane formula |
Where 2-Deep Fits
- Two pallets per SKU, many SKUs.
- No deep-reach truck, which double-deep needs.
Three or more per SKU: see 3-deep and 4-deep.
Common questions
What is the difference between 2-deep push-back and double-deep rack?
Both hold two pallets per level. Double-deep needs a deep-reach truck; push-back rolls the back pallet forward for any truck.
How many pallets fit in a 2-deep push-back lane?
Two per lane per level, so 8 in a lane 4 levels high. A 96-inch bay usually holds two lanes of 40-inch-wide pallets.
Can I convert selective rack to 2-deep push-back?
Often yes. We check frame depth, beam capacity and floor slope first.
