Gravity vs. Powered Conveyor: Which One Should You Choose?
A practical, side-by-side comparison of gravity and powered roller conveyors — cost, throughput, control and the situations where each one wins.
It's the most common question we hear from operators planning a new line: gravity or powered? Both move loads on rollers, but they solve very different problems.
Gravity roller conveyor — when simple wins
Gravity rollers use a slight downward slope (usually 2–4°) to let cartons or totes roll on their own. No motors, no controls, no maintenance contract — just rollers, frame and bearings.
- Lowest capital cost
- Easy to install and reconfigure
- Ideal for loading docks, returns and short manual lines
Powered roller conveyor — when control matters
Powered rollers use motors and drives (24V MDR, line shaft or belt-driven) to move loads at a controlled speed and to support accumulation zones.
- Consistent, predictable throughput
- Zero-pressure accumulation
- Full WMS/WCS integration
- Suitable for long runs, merges and automated sorting
Side by side
| Gravity | Powered | |
|---|---|---|
| Capital cost | € | €€€ |
| Throughput | Variable | Predictable |
| Energy | None | Low (24V) – Medium |
| WMS integration | No | Yes |
| Maintenance | Minimal | Scheduled |
The hybrid reality
Most real operations use both: gravity at the docks and returns, powered through the core automated flow. The right partner designs the handoff so loads transfer smoothly without manual lifting.

Frequently asked questions
Is a gravity conveyor cheaper than a powered conveyor?+
Yes. Gravity conveyors have no motors, drives or controls, so capital cost is typically 50–70% lower than an equivalent powered conveyor. However, throughput, accumulation and integration are limited.
When should I use a powered conveyor instead of gravity?+
Choose powered when you need predictable throughput, zero-pressure accumulation, WMS/WCS integration, controlled merges, or transport over long horizontal distances without manual intervention.
