Pallet Handling Conveyor Systems for Medium and Heavy Loads.
Compare accumulating and non-accumulating pallet conveyors for medium-weight and heavy-duty applications, including CDLR, drag-chain, slat, transfer, and turntable configurations.
Choose the Right Pallet Conveyor.
The correct pallet conveyor depends on unit-load weight, pallet construction, bottom condition, runner orientation, accumulation requirements, transfer points, and operating environment. ACSI manufactures the conveyor equipment; integration and installation are provided through ACSI distributors.
Model 22ACDE provides photo-eye controlled, air-operated accumulation for documented medium-weight pallet, drum-filling, large-carton, and slip-sheet applications. Its standard maximum unit load is 1,000 lbs., subject to the published load-capacity chart and application review.
ACSI heavy-duty families cover CDLR transport, pallet accumulation, drag-chain conveying, slat conveying, curves, direction changes, staging, and loads up to 4,000 lbs. on designated models.

Use this starting comparison to match pallet weight, load support, accumulation, positive drive, and transfer requirements to an ACSI conveyor family. Final selection requires application review.
| Model / Family | Best Fit | Search-Friendly Description | Typical Decision Point |
|---|---|---|---|
| 22ACDE | Compatible medium-weight pallets and slip sheets | Medium-duty photo-eye controlled chain-driven accumulation conveyor with a published 1,000 lb maximum unit load. | Choose when the verified pallet bottom, orientation, load, and accumulation requirements fit the 22ACDE specifications. |
| 251CRR / 267CRR | Pallets, drums, oily conditions | Heavy-duty CDLR chain-driven live roller pallet conveyor for positive-drive handling. | Choose when roller conveyor is preferred and load support is spread across rollers. |
| 350CRR | Heavy pallets and drums | Heavy-duty CDLR conveyor with 3-1/2 inch rollers for rugged pallet handling. | Choose for heavier duty cycles, larger rollers, and demanding plant-floor applications. |
| 251ACDA / 251ACDE | Pallet accumulation | Pallet accumulation conveyor using air-operated chain-driven live roller zones. | Choose when pallets must queue without damaging upstream loads. |
| DC / DCE | Drag-chain pallet transfer | Low-profile drag-chain conveyor and photo-eye accumulating drag-chain conveyor. | Choose when chain contact, pallet orientation, or transfer geometry fits the application better than rollers. |
| SL | Rugged positive drive | Slat conveyor for heavy industrial unit loads and pallet handling applications. | Choose when a continuous carrying surface is required. |
Both are CDLR pallet conveyors. The 251CRR / 267CRR family fits many positive-drive pallet and drum applications, while the 350CRR uses larger rollers and heavier construction for more demanding heavy-load conveyor systems.
The DC is a drag-chain conveyor for heavy pallet handling. The DCE adds photo-eye controlled air-operated accumulation for applications where pallets or skids need controlled queuing.
Pallet Handling Conveyor Questions.
Pallet conveyor selection commonly depends on load weight, pallet construction, bottom condition, orientation, accumulation needs, and transfer geometry. ACSI options include chain-driven live roller, drag-chain, slat, and accumulating pallet conveyors.
Yes, when the pallet and application fall within the verified capacity and support requirements of the selected model. Model 22ACDE is documented for medium-weight pallets and photo-eye controlled accumulation.
Drag-chain conveyors are often selected when pallet orientation, low profile, chain contact, transfer requirements, or load geometry make roller support less ideal.
ACSI manufactures the conveyor equipment. System integration and installation are provided through ACSI distributors, who coordinate the complete application around the project requirements.
