Push Back Racking – Gravity Cart High Density Storage Solution

Tired of limited warehouse space and slow pallet handling? Push back racking features inclined rails and nested gravity trolleys as shown in the 3D drawing. It’s a mechanical LIFO storage system with all loading/unloading done from the front aisle. No electric power is required, striking a great balance between storage density, picking efficiency and safety, widely used in cold storage, manufacturing, auto parts and 3PL logistics.

1. Push Back Racking Structure

The full system includes blue main rack frames and orange gravity trolley assemblies.

The upright frames have adjustable punched holes and diagonal bracing for stability, with optional front column guards to avoid forklift damage.

The core highlight is the layered nested trolleys installed on sloped steel rails, holding 2–6 pallets deep per lane. Made of thick welded steel with wear-resistant rollers, each lane has an independent trolley group for separate SKU storage, with zero electronic parts for easy maintenance.

2. How the Trolley System Works

When loading, the forklift stays in the outer aisle and pushes trolleys backward as more pallets are stacked.

When unloading, gravity slides all remaining pallets forward automatically after the front pallet is removed. It follows strict Last-In, First-Out stock rotation for batch goods.

3. Core Advantages

Larger storage capacity: It creates 50%–80% more pallet positions than standard selective racking by cutting redundant aisles, while picking far faster than drive-in racking.

Less damage & safer operation: Forklifts never drive inside the rack frame, drastically lowering frame collision risks. Built-in pallet stoppers prevent load shifting and cut long-term repair costs.

Wide environmental adaptability: The all-steel trolley structure works reliably from -30℃ freezers to regular factory warehouses. Galvanized finishes are available for humid or coastal environments.

Flexible for multiple SKUs: Independent trolleys per lane support separate product batches, much more versatile than drive-in rack which only fits single bulk goods per lane.

Low maintenance: Only occasional roller lubrication is needed, with a service life over 15 years under regular use.

4. Suitable Industries

Cold chain & freezer warehouses: Fewer aisles reduce cold air loss, and trolleys perform well in sub-zero temperatures.

Food & beverage distribution: Fast front picking speeds up mass dispatch of canned and bottled products.

Auto parts factories: Batch component storage with minimal rack and goods damage.

Wholesale & 3PL providers: Balances high storage volume and multi-product classification.

General manufacturing: Ideal for batch-produced finished goods with steady turnover.

5. Global Compliance Standards

Kingmore push back racking meets international industrial standards for export: EN 15512 & FEM for Europe, ANSI MH16.1 / RMI for North America, and NBR safety specs plus metric drawings for Brazil and Latin America. We provide customized layout design, load calculation reports and anti-rust test certificates for project bidding.

6. Who Should Choose Push Back Trolley Racking

This gravity cart system fits you perfectly if you lack warehouse floor space, store batch LIFO goods, run cold storage, want to reduce collision losses, or manage multiple medium-volume product lines.

Conclusion

Push back trolley racking fixes the drawbacks of selective rack’s low density and drive-in rack’s safety risks. Its purely mechanical gravity design brings stable long-term returns for warehouse operators across the globe.
