Carton gravity lanes
Inclined roller or wheel lanes move cartons from replenishment side to pick face, supporting FIFO movement for case and each-pick operations.
Flow Racking
Carton Flow Rack
Gravity carton lanes with separate replenishment and picking faces for FIFO case, box and each-pick operations.
Quick Answer
What is Carton Flow Rack?
Carton Flow Rack uses inclined wheel or roller lanes to move cartons from a replenishment side to a front pick face. It suits active case-pick SKUs where FIFO presentation and aisle separation are useful. Real carton samples must be tested for base condition, lane angle, stopping, skew and crush risk.
Typical applications
Where This System Fits
- Active case-pick modules with known load units.
- Projects where carton base, lane angle and replenishment face can be checked before layout approval.
- Teams needing a clearer alternative to generic storage for cartons, cases and boxes.
- Operations that can maintain labels, replenishment rules and housekeeping.
Operating logic
How This Product Works
Review the operating principle, load movement and main configuration checkpoints before comparing a system for the application.
Carton sample validation
Carton stiffness, base condition, loaded weight and label position affect movement, so the actual carton sample should be checked before confirming lanes.
Separate pick faces
Replenishment happens behind the rack while operators pick from the front, reducing aisle conflict and keeping fast-moving cartons presented in sequence.
Carton flow inputs
Confirm carton dimensions, weight, lane depth, stop type, divider arrangement, pick height, replenishment method and any workstation or conveyor connection.
Technical notes
- Carton Flow Rack is designed around carton behaviour in a gravity lane. Corrugated base quality, tape seams, case weight, lane guides, front stops and rear loading discipline decide whether cartons advance cleanly to the pick face.
- The handled unit is cartons, cases and boxes. That unit should be reviewed with photos or samples because footprint, base shape, edge condition, packaging strength and loaded weight change the rack selection more than a generic product name.
- Access is specific to the application: the operating face, replenishment side, aisle width, reach height and handling equipment have to match the real workflow. Carton Flow Rack should therefore be quoted from a site and load brief, not from an unsupported capacity claim.
- Rotation is process-led unless the selected mechanism physically advances the load. Labels, batch rules, min-max triggers, kanban cards or job paperwork must be aligned with the rack so operators know what to pick and what to refill.
- Case seams, brake clips, lane guides, fifo pick face are useful terms for internal selection because they describe the practical interface. They should not be turned into unsupported performance claims, published capacities or promises about availability.
- Sample carton testing for flow and stopping is the main condition to check. Ignoring this point leaves the drawing apparently correct but fails to address awkward picking, replenishment, load protection and safe daily handling.
- Carton Flow Rack should be compared with bin flow rack and longspan shelving because buyers often group these systems together. The difference is the load unit, access face and confirmation input, not only the visible steelwork.
- For quotation, Runda Rack should receive load photos, sample dimensions, access constraints, expected stock rotation, environmental conditions and future change expectations. Those details allow a product-specific configuration without adding unsupported dimensions or engineering statements.
- Carton-flow design begins with the box base. Corrugated flute direction, tape ridges, crushed corners, shrink wrap, bulging contents and humidity can all change how a carton rolls, so a test bay with real stock is more reliable than a catalogue lane sketch.
- The pick face should be engineered around hand motion: front stop height, label strip, lane separator, carton overhang and the first-pick grip decide whether operators can remove the case cleanly without dragging the next case forward.
- Replenishment discipline is as important as hardware. Case lanes should avoid mixed batches unless the process deliberately controls them, and reserve cartons should be loaded from the rear in the same sequence expected at the front face.
- Carton lane trials should record first-carton release force, last-carton availability, side-guide rub marks, carton skew, crushed lead edges and whether the stop lets the picker grip the case cleanly. These carton behaviours are not tote behaviours.
- Configure full-width rollers for soft boxes, wheel tracks for firmer cartons, lane dividers for SKU separation and brake clips on deeper beds according to the sample-box trial.
- Carton flow should describe case faces, front stops, rear loading, expiry batches and carton quality. It should not drift into workstation takt language unless the rack is actually serving a production cell.
- Carton-flow examples include beverage cases, sealed retail cartons, health-and-beauty cases, expiry-date cartons and broken-case replenishment. The trial should measure skew, hang-up, case crushing, front-stop grip and rear-load behaviour.
- Case-lane options include skate wheels, full-width rollers, lane guides, entry guides, brake clips, rear loading shelves, pick lips, label beams and permitted carton overhang.
System strengths
Advantages
- Matches the storage interface to cartons, cases and boxes rather than forcing a generic bay.
- Makes access method, replenishment side and operator contact points explicit.
- Creates concrete confirmation points for quotation and layout review.
- Helps separate this product from similar storage systems during selection.
Conditions to check
Limitations and Trade-Offs
- Sample carton testing for flow and stopping must be resolved before final configuration.
- Unsuitable when the load unit varies beyond the selected support or lane arrangement.
- Stock rotation and traceability still need operating procedures and labels.
- Project-specific safety, floor, fire and handling constraints require confirmation.

Compare Common Alternatives
- Bin Flow Rack
- Carton Flow Rack is selected for cartons, cases and boxes; bin flow rack should be reviewed when its load unit or access method is a closer match.
- Longspan Shelving
- Compare longspan shelving when sample carton testing for flow and stopping cannot be resolved within the Carton Flow Rack arrangement.
Configuration inputs
What to Confirm Before Selection
- Carton base, lane angle and replenishment face.
- Actual samples or photos of cartons, cases and boxes.
- Operating face, replenishment route, aisle width and reach height.
- Label, batch, FIFO, kanban or job-control rule.
- Handling equipment, trolley, crane, lift truck or manual process.
- Floor, anchoring, fire, inspection and environmental constraints.
Product questions
Frequently Asked Questions
- When should Carton Flow Rack be considered?
- Consider it for active case-pick modules when the load unit is cartons, cases and boxes and the access method can be confirmed before quotation.
- What is the main limitation of Carton Flow Rack?
- The main limitation is sample carton testing for flow and stopping. This should be checked with samples, site details and the intended handling process.
- What information is needed before configuration?
- Provide carton base, lane angle and replenishment face, sample dimensions, access route, handling equipment, rotation rule, environment and any safety or inspection constraints.
