Technical specifications
| Specification | Value |
|---|---|
| Systems | Drive-in, push-back, gravity pallet flow and semi-automatic pallet shuttle |
| Access and rotation | Drive-in and push-back: LIFO in the illustrated configurations; pallet flow: opposite loading and picking sides for FIFO; validate shuttle mode from access arrangement |
| Depth | The catalogue shows push-back two to four pallets deep; size other systems around pallet, rails and handling equipment |
| Pallets and SKUs | Pallet format, weight, overhang, pallets per lane and SKU homogeneity must be surveyed; no universal load is published |
| Compatible equipment | Guide rails, roller beds, push-back carts, guards and shuttle by system; compatibility with the racking must be checked |
| Site and handling | Slab, anchors, clear height, aisle width, truck, impact protection and load signage must be checked on the layout |
| Maintenance and safety | Inspection of rails, rollers, carts, sensors and guards belongs in the system instructions and maintenance plan; no system is presented as maintenance-free |
| Cold rooms | Frequent use is documented for drive-in and shuttle; temperature, corrosion, hygiene and equipment must be validated for the room |
Storage catalogue, printed pages 10–17: drive-in, push-back, pallet flow and pallet shuttle. The pages describe principles but publish no loads, percentage space gain or complete anchoring and maintenance instructions.
Available products
| Drive-in racking | Storage lanes the forklift enters to place pallets on continuous rails; the illustrated single-access configuration follows LIFO. |
|---|---|
| Push-back racking | Two to four pallets deep on roller carts in the catalogue: each loaded pallet pushes the previous ones back and the last one remains available at the front (LIFO). |
| Pallet flow racking | Lanes of slightly inclined roller beds: pallets move by gravity towards the exit. Double access supports FIFO; a single-access layout must be confirmed. |
| Pallet shuttle | A semi-automatic remote-controlled shuttle carries the pallet along the rails and positions it accurately; sensors, pallet compatibility and LIFO/relative FIFO mode must be confirmed. |
Which high-density storage system to choose?
Four questions guide the choice of system:
- Stock rotation: strict FIFO (use-by dates, traceability) → pallet flow; LIFO acceptable → drive-in or push-back
- Pallets per SKU: most systems require homogeneous volumes by lane or level; the number of SKUs to mix must be studied
- Flow and trucks: inbound/outbound frequency, travel direction, aisle width and lift height guide the choice; no universal threshold is published
- Environment: in a cold room, check temperature, corrosion, hygiene, access and maintenance before selecting a compact system
Drive-in, push-back, pallet flow or shuttle: comparison
| System | Principle | Rotation | Typical use |
|---|---|---|---|
| Drive-in | The forklift enters the lane | LIFO / relative FIFO | Large homogeneous volumes, cold rooms |
| Push-back | Pallets pushed on roller carts, up to 5 deep | LIFO | Medium rotation, products available at the front |
| Pallet flow | Pallets moved by gravity on rollers | LIFO single-access or FIFO double-access | Date-sensitive products, planned rotation |
| Pallet shuttle | Remote-controlled semi-automatic shuttle | LIFO / relative FIFO | Large volumes; throughput and compatibility to study |
