What Are The Different Types of Pallet System Conveyors?

Motor-Driven Roller Conveying Systems

A Motor-Driven Roller (MDR) is a conveyor system where the rollers have an integrated motor inside their tube. The motor is typically a low-voltage and brushless DC (24V DC) motor. It is directly connected to a gear system, which drives power efficiently and with minimal noise as the roller rotates. The entire system is self-contained, meaning no external motor or chain drive is needed.

Energy Efficiency – Since MDRs run-on-demand and activate only when product is present, they consume significantly less power than continuous-drive systems.

Quiet Operation – Lacking chains or belts, MDRs generate minimal noise, making them ideal for indoor environments.

Low Maintenance – With fewer moving parts and an enclosed motor, there’s less wear and tear compared to traditional conveyor systems.

Modular & Scalable – MDR conveyors can be easily reconfigured, expanded, or integrated into automated systems.

Zero-pressure Accumulation – The conveyor rollers have sensors that detect and hold products in specific zones, ensuring no contact between items and reducing accidental damages.

 

Chain-Driven Live Roller Conveying Systems

These conveying systems, known as CDLR conveyors, use a system of sprockets welded to the rollers and a long looped chain that runs along the length of the conveyor. A motor at one end of the conveyor drives the chain which engages the sockets, giving power to the rollers, which have the capability to smoothly move heavy loads like pallets, drums, totes and other unit loads. Most CDLR conveyors are built to withstand harsh conditions and tough treatment, that's why the majority of the systems are welded with thick steel.

Positive Drive – The chain-driven prevents slippage or loss of power, providing a reliable and consistent drive.

High Throughput – CDLR conveyors are designed for high-volume use for even heavy or demanding loads.

Customizable – These conveyors can be customized for varying lengths, frame dimensions, roller capacities and support legs depending on the application. They can also be equipped with Accumulation Control features.

Low Maintenance – CDLR conveyors are relatively easy to maintain, with minimal downtime requested for repairs or adjustments due to their rugged and durable nature

MDR conveyors operate on lower voltage (DC) are best for lighter loads, energy efficiency, and quieter operation, while CDLR conveyors require higher voltage (AC) and excel in handling heavier loads, rugged environments and continuous operation.
