Roach Accumulation and Powered Roller Conveyors
Accumulation conveyors hold products in a line without letting them push against each other, so a stopped downstream station does not crush or jam the products behind it. LaRos supplies Roach zero pressure accumulation conveyor and motorized powered roller conveyor, and can add LaRos controls built for the application.

How zero pressure accumulation works
The conveyor is divided into zones, each with a sensor. When a product stops at the end of the line, the zone behind it stops as soon as the next product arrives, and each zone upstream does the same. Products queue with gaps between them instead of pushing against each other, then release zone by zone when the line restarts.
Powered roller conveyor with 24V motorized rollers drives each zone with its own motor, which keeps the conveyor quiet and runs zones only when product is present.
Choosing a drive
- Motorized roller (PRA): quiet, zone-by-zone power, for packages and totes
- Line shaft (LSZ): a wide range of package sizes on one line
- Chain driven (CDA): heavier unit loads and pallets. For transport without accumulation, see Roach CDLR.
Send us the products, their sizes and weights, and the rate, and we will recommend the model. Also see Roach gravity roller conveyors and belt conveyors. More about Roach conveyors from LaRos
