High-capacity solutions engineered for seamless warehouse storage logistics, retail distribution hubs, and commercial spaces worldwide.
Dynamic push-back racking combines the density of drive-in systems with the versatility of selective setups. By consolidating multi-pallet layouts on inclined tracks, it increases cubic storage footprint utilization by up to 75% compared to conventional layouts.
Designed around Last-In, First-Out (LIFO) material dynamics, push-back storage systems utilize nesting cart assemblies on sloped rails. This structural logic guarantees that retrieval faces are continuously replenished by gravity as pallets are extracted.
Unlike standard drive-in configurations, forklift trucks never enter the racking system. Operating strictly within the main access aisle, operators avoid collisions with upright structures, significantly reducing equipment repair downtime and upkeep costs.
Industrial warehousing is undergoing a profound structural evolution. Rising warehouse land costs, the growth of global cold-chain distribution, and the demand for fast SKU buffering have prompted operators to seek storage methods that yield high density without compromising SKU pick rates. Standard static selective racks require multiple access aisles, occupying valuable warehouse volume. Dynamic push-back racking systems resolve this challenge by converting multiple aisles into deep, high-density storage lanes, accommodating from 2 to 6 pallets deep.
By leveraging custom-manufactured heavy-duty carrier carts, our push-back storage designs allow individual product lanes to maintain separate SKU groupings. This structure optimizes load-holding capacities while granting quick access to individual items. Forklifts do not need to navigate inside rack structures, resulting in cycle times up to 40% faster than those of drive-in systems.
We design, manufacture, and test our push-back systems to withstand heavy loads and maintain peak structural integrity under seismic conditions.
Our dynamic push-back carriages are constructed from high-grade structural steel and equipped with CNC-machined steel wheels. Heavy-duty bearings are shielded against dust and debris, ensuring smooth operation on 3.5% incline rails. This angle is calculated to balance pallet forward flow with push-back force requirements.
Built with robust roll-formed or structural steel column frames, our upright units use tear-drop or keyhole hook configurations. Heavy-duty box beams feature a 4-hook connector connection to resist torsional loading during intensive pallet movement cycles.
Safety is critical in high-density storage operations. Our systems feature physical cart travel stops, anti-lift locks to prevent accidental carriage derailment, and front bumper plates. These design features protect both warehouse workers and cargo from dynamic impact forces.

Technical answers regarding structural integrity, safety tolerances, and layout design.
Push-back systems use nested, rolling carts on an incline to store pallets using LIFO (Last-In, First-Out) inventory logic, loading and unloading from a single aisle. Gravity-flow systems rely on rollers and FIFO (First-In, First-Out) logic, requiring separate aisles for loading and picking. Push-back racking systems are typically more space-efficient for operations with moderate SKU diversity and high pallet volume.
The incline angle is generally engineered between 3% and 4% (about 5/8 of an inch per foot). This slope provides enough gravity to flow the remaining pallets forward to the aisle face when the front pallet is retrieved, while keeping the physical force required for forklift loading within safe limits.
Yes. Because our push-back design places pallets on custom-welded steel carriages, the bottom of the pallet does not contact the rails directly. This helps prevent pallet damage and allows for a variety of wooden, plastic, or metal pallet designs to be used safely, provided they fit the cart's dimensions and load ratings.
We design and manufacture our racking systems to align with international engineering standards, including RMI ANSI MH16.1, FEM 10.2.02, and EN 15512. For installations in seismic zones, we perform finite element analysis (FEA) to determine requirements for thickened base plates, heavy-duty floor anchor bolts, and specialized diagonal cross-bracing.
We offer comprehensive OEM/ODM customization. This includes custom lane depths (ranging from 2-deep to 6-deep), hot-dip galvanized finishes for high-moisture or cold environments, tailored beam and column dimensions, and custom baseplates to meet specific concrete slab requirements.
