Gravity Flow Lanes and Pick Faces

Building a carton flow lane from rail, wheels and roller bearings that keeps moving for years.

The problem

A flow lane has one job: deliver the next carton to the picker's hand at a speed a person can catch. Lanes fail by stalling (too little slope, too much roll resistance) or by running away (too much slope, nothing holding speed).

Step by step

How the specification is built

1

Define the load

Carton base size, weight and base material. The shortest carton sets the wheel pitch; the heaviest sets the wheel and rail choice.

2

Choose wheel material

Plastic wheels for cartons, quiet picking and no marking. Metal wheels for heavy, hot, sharp-based or abrasive loads.

3

Set wheel pitch

Close enough that at least three wheels are always under the shortest carton, so it never drops between wheels.

4

Set slope and length

Slope is set on site to give controlled flow, then checked at both full and empty lane conditions.

5

Fix the rail

Rail profile is matched to the rack beam fixing, cut to rack depth and levelled across the lane width.

6

Plan the spares

Hold wheels and end caps for the lanes you run; a stalled lane is usually one seized wheel.

Frequently Asked Questions

Two rails or three?

Two under the carton edges is standard. Add a third down the centre for wide or flexible bases that would sag between the rails.

What stops cartons accelerating in a long lane?

Reducing slope over a longer run, or fitting brake wheels in the last section before the pick face.
