Heavy Duty Chain Driven Pallet Accumulating Live Roller Conveyor

ACSI Model 251CDA is a heavy-duty chain-driven live roller conveyor for mechanically controlled, zero-pressure accumulation of compatible pallets and unit loads. Individual zones stage loads without pressure building between adjacent pallets, using product-actuated sensing and positive roller drive. With heavy channel construction, enclosed chains, and a published maximum unit load of 4,000 pounds, the model supports pallet buffering and controlled release where a mechanical zone-control arrangement fits the application.
