CDLR Conveyor Questions.
CDLR means chain-driven live roller. Each driven roller is powered through chain and sprocket engagement, providing positive drive for heavier unit loads.
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.
Yes. Automated Conveyor Systems, Inc. manufactures CDLR conveyors in West Memphis, Arkansas for standard catalog applications and custom engineered conveyor systems.
Yes. ACSI offers heavy-duty pallet accumulating conveyor models that use chain-driven live roller construction with mechanical or air-operated zone control.
