What does CDLR mean?
CDLR means chain-driven live roller. Each driven roller is powered through chain and sprocket engagement, providing positive drive for heavier unit loads.

Buyer Questions
CDLR Conveyor FAQs.
Answers to common questions about positive drive, heavy loads, pallet accumulation, and ACSI CDLR construction.
When is CDLR better than belt conveyor?
CDLR is usually preferred for pallets, drums, containers, and heavy loads where positive roller drive, rugged construction, and industrial durability are more important than a continuous belt surface.
Does ACSI manufacture CDLR conveyors?
Yes. Automated Conveyor Systems, Inc. manufactures CDLR conveyors in West Memphis, Arkansas for standard catalog applications and custom engineered conveyor systems.
Can CDLR conveyors accumulate pallets?
Yes. ACSI offers heavy-duty pallet accumulating conveyor models that use chain-driven live roller construction with mechanical or air-operated zone control.
