Carton Flow Racking

Carton flow racking is gravity-fed case picking: load from the rear aisle, pick from the front, FIFO by design. SJF says incorporates gravity rollers right into the rack shelf itself. MH-USA says Pick rates increase 2–3× compared to static shelving. Interlake Mecalux says Carton Flow Racks separate picking and stocking tasks into different aisles.

How carton flow works

SJF says incorporates gravity rollers right into the rack shelf itself and The rack shelves are set with a decline pitch to allow gravity to flow from the in feed side (rear) to the pick side (front). MH-USA lists Load from the back, pick from the front and None — 100% gravity powered. Interlake Mecalux says Inclined wheel and roller platforms and Carton Flow Racks separate picking and stocking tasks into different aisles. CSSYES says cartons are fed from one side, and retrieved from the other.

Depth, weight, incline, and published pick rates

MH-USA lists 4 to 8+ cartons per lane typical, 5 to 75+ lbs per carton, and 3° to 5° typical incline. MH-USA says Pick rates increase 2–3× compared to static shelving with comparison cells 60–100 lines/hr versus 150–300+ lines/hr. Interlake Mecalux says save up to 75 percent of labor costs compared to a static storage solution. UNEX says UNEX carton flow solutions increase throughput by up to 150% compared to picking from pallets. MH-USA says Skatewheel lanes are most economical ($50–$150/lane).

Frequently Asked Questions

What is carton flow racking?

SJF says incorporates gravity rollers right into the rack shelf itself and Carton flow provides FIFO (First In, First Out) inventory control and is used in for a wide range of products. MH-USA lists Tilted roller or wheel-bed lanes installed inside pallet rack bays that use gravity to move cartons, cases, and totes from the loading side to the picking face. IMH says Carton Flow Racking is a dynamic, gravity-fed storage system designed to improve efficiency in order picking and inventory rotation.

How deep and wide are carton flow lanes?

MH-USA lists 4 to 8+ cartons per lane typical and Typically 4 to 8 cartons deep per lane and Each lane holds 3–8 cartons of the same SKU. MH-USA lists 5 to 75+ lbs per carton and Handles light to medium cartons (5–50 lbs). Dexion says The width of the tracks can be adjusted in steps of 11.5mm.

Does carton flow require power?

MH-USA lists None — 100% gravity powered and 3° to 5° typical. UNEX says Gravity! The most powerful (and free) force in the universe. CSSYES says Utilizes gravity to bring product to the face of the picking aisle. Dexion lists gravity-fed roller beds or wheels.

Can carton flow drop into existing pallet rack?

MH-USA says carton flow tracks are designed to drop into standard pallet rack bays. Dexion says Carton Flow beds can be retrofitted into existing pallet racking systems. IMH says Yes carton flow beds can often be retrofitted into standard pallet racking frames. UNEX says SpanTrack and Shelf Track’s patented design easily drops into existing.
